    I worked in the garage Saturday from 8pm till 2am. I should have just gone till 1:30.
    I started with assembling a 1967 Quadrajet made by Carter for Rochester.
    since my 4.3l engine had a computer controlled Carburetor at birth I had to put something else on it to stand alone when I first built the motor for the jeep. The seller of the engine knew a would need something else but hadn't gotten there with his project but he had an 80s quadrajet for a Pontiac that he threw in the deal.
    Now... Chevy and GMC quadrajets have an angled fuel inlet for the passenger side fuel pump and everything else had a straight inlet / filter housing. You can make it work but it put the fuel line against the thermostat housing. This carb I am working on today is manual choke which frees up a lot of clutter and mhas the better fuel inlet for my needs.

    Something I wasn't expecting was this unique substitute for the needle valve assembly.
    [​IMG]20190713_203416 by Joe with a jeep, on Flickr

    I just reused what it had since the kit parts don't work (this is a kit listed for this exact carb from summit based on the tag). Another odd thing When I placed the base gasket on the intake manifold.

    In other news I dropped the Transmission out of the jeep again. This time with the transfercase attached. I didn't think to bolt the T-90 to the D-18 before installing into the Jeep now i believe the omix-ada mainshaft is too long and everything is locking up when the transfercase is torqued down. I intend to make some shims between the Transmission and transfercase and move on. From what I can tell the extra material is in the sliding gear mating splines this is forcing 2nd gear into the synchro assembly and mainshaft making it want to be in 3rd and 2nd ratios on the mainshaft while in neutral. The shims will hopefully allow me to dial in on my 2nd gear clearance.

    The brakes are waiting on me getting the wheel bearing races seated and I need to order 2calipers 2flex hoses 4 banjo bolts 12 backing plate bolts and organic pads for all of the calipers. I plan to run the single master cylinder this winter to get a feel for the pedal force then adjust the master cylinder bore as needed.

    The steering looks like it needs to stay as it is for this season. The needle bearings on the bellcrank are destroyed. I will get some new bearings or have bushings made for the bellcrank but it looks like manual Saginaw is the way to go for me.

    the passenger rear wheel is on the jeep! With calipers, a rotor, and pads and everything clears.
    I put the driver side flange on without checking the number of backing plate bolts... 3 the flange doesn't want to come back off so I will see abouts renting a puller.
    The front still needs calipers and pads. (I need to take the driver side rear caliper in to get banjo bolts and then depending on thread get the front calipers to match. I also need to rent the big socket for the front bearing preload. Then I will mount the hoses and run new brake lines.
    The Transmission is on the bench to be pulled apart. It was weird today I had it on the bench bolted to the d-18 and it was bound up then it wasn't after I loosened the input cap so I put the t-case gear on with nut and spun it in all the gears it had a lot of drag in and seemed to have something out of line because when going back and forth on the wrench in gear it would have a bit of slack before dragging so I'm pretty sure it might be a needle bearing issue. Basically It's coming apart... again.
    I did get the bellcrank pulled apart and cleaned. Right now tapered bearings seems to be my best option on steering. That should get it down to 1/16 of a steering wheel turn of play.

    Serial #'s should be marked on your Qaudrajet. Model # should begin with ' 15..... ' Get a rebuild kit fort that one. Run you about $28 , but it's the only way for " Miles " . :schooled:. Float levels metering rods , linkages, ect. , all have measurements to adjust to.
    After that , I used to rebuild these in my younger days. They were built in my Hometown . Do this right & you'll have one of best off road carbs available , IMO.

    I started today with this at 8:40am...
    [​IMG]20190722_000300 by Joe with a jeep, on Flickr

    Pulled out some stuff that wasn't letting it turn right. (Only left, not the way the engine wants to turn it)

    [​IMG]20190727_125814 by Joe with a jeep, on Flickr

    Including a broken hard drive magnet, shift tower bolt, 1 too many countershaft needle bearing spacers.

    [​IMG]20190727_130419 by Joe with a jeep, on Flickr

    Then Bent the ear on the rear washer to lock into the case since that was causing weird feeling when turning the cluster gear when combined with the extra spacer.

    [​IMG]20190727_130912 by Joe with a jeep, on Flickr

    Fixed a reverse idler shaft that was too tight.

    [​IMG]20190727_130041 by Joe with a jeep, on Flickr

    Reassembled without losing any needle bearings.

    [​IMG]20190727_131837 by Joe with a jeep, on Flickr

    [​IMG]20190727_132233 by Joe with a jeep, on Flickr

    Checked everything worked. Mounted the transfercase and crossmember. Got them all back in the jeep (without a jack and it took darn near 3hrs) then I had the last gasket for the q-jet... so I had to make sure it worked and the Transmission too, so on went the grill and battery and a fuel line. It ran long enough to get to 190deg on the 5th or 6th go. I have some noisy lifters and The carburetor stripped out it's fuel filter housing threads. The weird float thing seems to be stuck but the Transmission and clutch work! Started cleaning up at 8:40pm

    Another thing I noticed is I think the oil and filter in this are as old as my kids And the two other cars we have in the driveway.

    Got a good amount done yesterday, and a little today. Brakes are assembled and tires are on but I could use some ideas for the rear brake hoses from calipers to frame. Fronts were easy peasy rears will need brackets and drilling. In another pay check I will order a $30 bellcrank repair kit. I hate the thing but time and money are getting scarce. In other news I had some material laying around and made some 3/4" crossmember spacers.

    I would have gotten more done today but it was a humid 87deg and I wasn't making much headway other than getting the clothes sweaty.

    Thursday my steering bellcrank rebuild kit arrived, and was immediately installed. I need to tighten the steering box end of the drag link but the steering play is down to about an inch at the parameter of the steering wheel. This was previously about a quarter turn of play. This was a crown kit Very happy with the time to money to improvement there.
    Hopefully it will last longer this time if I don't take it swimming.

    [​IMG]20190817_002322 by Joe with a jeep, on Flickr

    To follow up on the brakes. I made some brackets... out of 12ga steel that bring the hoses inboard and below the frame just in front of the rear bump stops. Then ran my line across the crossmember that would normally hang a f-134 muffler. Then Friday I found my master cylinder rebuild kit. I feel like I won the lotto there since it was bought around 2005. Put the master cyl together and filled it with fluid. Bled the brakes found one leak at a union on the frame rail to the rear.one wheel had an open bleeder and another had a jammed bleeder. Pumped the brakes and held... and held... then I got tired and put a handle on the pedal against the dash and let it hold.

    [​IMG]20190817_002352 by Joe with a jeep, on Flickr

    My drive shafts are in place. The rear is good. The front had a u-joint out on the axle end.
    I need to tighten the Transmission cross member and make sure the Transmission is bolted down.
    Then I think I can put this jeep back with its tires on the ground for the first time in 4years since the t-90 blew and a front wheel bearing failed taking out the brakes.
    I had to call state to ask what the deal was on my historic plates (3-6 week turnaround and it's been since June. Sounds like my application was lost so I will need to drive to the State Capitol and take care of that in person luckily that will be same day service.

    Sadly When the wife got home Thursday and found me in the garage, we got in an argument. She kept insisting that I need to get new tires on the Jeep I kept saying that's out of budget. She said I'm no good to her dead and I've spent too much time and money to loose it to some 12yr old bald tires. I asked if I could put the better 2 on the m416 since it's tires are not matching and likely 30years old she said I had to get 4 tires for the jeep.
    Anyone have some 7.50-16 tires that look appropriate for a snow plow and service jeep? I have trans trac lts I want to stick with 32" diameter but could use 4 or 6 ply these 8 plus are giant hockey pucks that work great in clay. I intend to enjoy this on road but still have some bite in the snow slush mud and clay. Thank you!

    Over the weekend I had an issue with the brakes being locked up.
    To recap I rebuilt my single reservoir and plan to order a split reservoir with the same bore or slightly smaller or larger based on feel. Well I didn't pull all of the residual pressure valve out I pulled the gasket and called it good. So since I have these awesome easy access floorboards I was able to swing the pedal arm clear pop the c-clip and let everything fly everywhere. Then clean and reassemble without the residual pressure valve which is in the base of the piston spring. Easy peasy, added the 2lb valve in line between the distribution block and the master cylinder. I don't think I have all the air out yet but dang it doesn't pull left OR right.
    Currently it takes one full pump to stop in low range.
    If I get all the air out and the pedal gets firmer great I will run a regular CJ5 split reservoir if it doesn't improve I will go with a slightly larger bore master cylinder.
    All 4 of my calipers are 2.9" diameter k10 calipers so this might play a part vs the smaller 2.5" bore calipers used with 7/8" thick rotors.

    2nd issue of the day is it still overheats and runs on. I think I need to check my timing Mark for tdc. It definitely has an exhaust odor.
    With timing set I will see if I can adjust the idle to smell like roses. I do have 02 sensors in the exhaust so that might be handy if my DIY displays still work and are accurate.

    Now the biggest issue: I can't figure this out.
    With the jeep in reverse I can idle backwards without stress or strain on the engine. When I put my foot down and release the clutch, the jeep will coast about 2ft without any noise then stop abruptly. I nearly lost the hard top. I thought it was my breaks at first but it happens with and without brakes applied. I thought it happened in both high and low reverse. In the forward gears it will cost easily. In neutral I can push the jeep both forward and backward with ease. Brakes seem free of drag. Both axle sides have the shim packs. It might have taken a little more effort to start out in reverse on the first few tries but it is a weird cost then bind and bark tires or spring forward and roll.

    A recurring item The Ross box is too close to the exhaust causing it to get harder to turn when the engine is warm. This has always been an issue with the 1st 3.3l v6 and this 4.3 I topped off the steering box and I can only really add a heat shield

    Basically today had a lot of data capture. It is frustrating to have the issues but I am getting the time right now to address these. The fall reunion is only 3 weeks away.

    Thursday I took a few hours off of work to leave town and run to the state motor vehicle office. I had mailed my application soon after a tornado hit the facility.
    In this picture you can see the Capitol building under repair in the distance. The hotel in the foreground is the location of the fall 2013 reunion if I have my years right.
    Between them was my destination.

    [​IMG]20190822_140622 by Joe with a jeep, on Flickr

    I thought I would have to wait forever, show a bunch of documents, and I was guaranteed to forget something. I forgot the checkbook of course. I pulled ticket 36 and they were on 32 but they finished the first person and 3 people left with them and I was next... ok.
    I had my plate on hand I told the situation and I said "I really don't care if I end up paying twice" she said I would not have to pay twice but she had to look thru the files and I may want to take a seat.
    I didn't sit.
    3 min later she's back and said "they processed it Tuesday" she printed my receipt and said I was good to go.
    What luck.

    So... I drove to work today.

    It's only about a 1.5 miles each way but it's something. No school zones but had to cross a 4 lane road then a hill and 2 railroad tracks in a 300ft stretch.
    Well I put my foot in it not really knowing what to expect from the 4.3l.
    I want to say the tach only hit 5500rpm before I was thru the intersection. I hit the hill, bang! never really noticed the sidewalk crossing was a level spot on the side of the hill... (long pause) clash! Then the 1st railroad track. Boom! I broke something.
    Yep the motor wasn't this loud before and something is grinding on the ground.
    I got stopped nice and quick. Look around and the cars behind me turned into the entrance to the scrapyard... and there I am. Broken down at the gate to the scrapyard in my rusty old jeep.
    My side pipe was hanging on the ground, and it was very hot so I threw it in the back and off I went.

    Made it to work.

    Exhaust manifold is fixed...
    [​IMG]20190828_204240 by Joe with a jeep, on Flickr

    When putting the 3.3l Chevy in I cranked my little flux core welder to the max and had at it. I am a bit surprised it lasted this long. while it was out I had to shorten it since a chunk was missing, and I took the opportunity to angle the outlet flange about 10deg forward of vertical (similar to the 134 outlet orientation) it works much better now and my steering box is happier.
    Now I need to adjust the rest of it.
    [​IMG]20190828_204324 by Joe with a jeep, on Flickr

    I was home for lunch today... actually I went right to the garage to tinker. Then I drove the jeep to work. I went much slower across that rough section and it went pretty well.
    After work I fueled up, then went to visit the local parts store since one of the guys had had to deal with this whole project even while I was sick.
    The brakes are a bit soft but stop well, I will bleed them again but I think a slightly larger bore for the master will be in the mix when I go to a dual reservoir. Reverse is getting better, it wasn't getting tight while coasting in reverse today. I adjusted timing and it seems better. It ran on a little today at one of the stops. I adjusted the idle mix back to 2 full turns off the seat the passenger bank was 2.5 and the driver side was more like 3 full turns off the seat for some reason. It was running better before adjusting the idle mix.
    I do need to install the choke control, I have a manual choke but it needs a cable bracket and i haven't seen a good diagram for the linkage but I'll look into that before running it much more.
    The steering is pretty intense
    One lockout hub isn't freewheeling well so I have both locked it also has a bad u-joint on the front pinion.
    so I need to pull it apart and sand the plastic bushing. I will do a tape measure alignment just to check that that is not the issue. The wife mentioned new tires before winter so I will get a proper alignment with the new shoes. It likely needs more caster but mostly I believe it is due to the wheel adapters needed to clear the calipers... and put the wheels out flush with the body. I feel like the Long term solution will be a Dana 30 with different lower profile calipers to keep the wheels out flush.

    Got home from camping... and well I guess I was looking for an excuse to drive the jeep around.
    Our family wagon sits a bit low and drags the hitch in the driveway once the cooler is in and trailer is hitched soo I had to use the jeep to move the trailer from in front of the house to the driveway.

    This is neither...

    [​IMG]20190902_140419 by Joe with a jeep, on Flickr

    I was testing the disk brakes while it was hooked up. It could definitely use a proportioning valve, but I am really happy with the pedal force and the face to windshield effect...
    Then I washed the jeep and trailer and backed the trailer in the jeeps spot in the garage.

    [​IMG]20190902_155523 by Joe with a jeep, on Flickr

    In other news I replaced the broken speedometer cable this time with 63", and it fits good! I changed the oil with only .5 miles on the oil, it seems like such a waste since the old oil flowed well and looked good.
    Oh well.
    Here are the old and new filters with install dates and mileage at install.

    Drove to work again, it is just far enough to get to temp and I have help if I need it.
    Adjusted the idle mixture and this is about 1200rpm
    21" hg vacuum
    Not much variation maybe 1/4" hg of vibration (seems good to me)

    It's been a little while...
    Friday before the fall reunion The jeep was running so well I decided to use the jeep to take the camper trailer to it's home about 10 miles north. 4 miles out it started starving for fuel. With the trailer attached I was pretty committed to press forward (and the rescue party would be coming from the destination). Luckily even though the engine wouldn't run over 2000rpm it would still lug up the hills. I got the trailer there and the engine was idling fine but the temp started climbing and it shut down. My father inlaw and I pulled the Carburetor apart and found a ruptured accelerator pump diaphragm and a clogged brass fuel filter.
    Borrowed the accelerator pump from the old ccc quadrajet and pulled the brass filter to run only a inline filter.
    Monday i was going to have the exhaust tucked up to the floorboard hat channels. Wound up the shop didn't get to it that day. Would up needing a new battery and the exhaust was finished noon Thursday of the reunion. I flat towed to the reunion and met up with Matt, John, Jeff, and the other Joe on the trails. Got to the first hill climb and half way up I started spinning wheels and noticed my extra temp gauge was reading 240f and the cluster was reading "HOT". After cooling I managed to bash the radiator against the front cross member and radiator fan due to a missing center grill mounting bolt. It developed a small leak but only under pressure. Saturday of the reunion Lee, Mturbo38, and I ran to the trails but once we got there my radiator was pissing on the ground. I had brought an lp torch plumbing flux and solder so we pulled the radiator plucked some fins and soldered the leak then time was up and we drove back to the museum. Once home from the reunion the radiator was still leaking so I parked it. Yesterday i was able to pull the radiator again and found the bellcrank mount did make a pin hole in the radiator so that area has been clearanced and soldered tight. With the radiator out I decided to look at the overheating issue. My cab heaters were blowing hot and were able to keep the engine from overheating. On a hunch I pulled the thermostat and tested it to a new 180deg unit. The new one more or less cycled from open to closed pretty rapidly and was lighter than what I had which opens at the same temp but doesn't close as rapidly. I kept the old but drilled a pair of 1/8 bleeder holes in the flange. With that I ran the motor with straight water and it settled at 200 to 210 deg at a high idle in the driveway. I'll have to drive it and see what happens but I believe I have a step in the right direction.
