The Jurassic Build 08-17-20

I had a little time to do some tear-down~

It's not too bad, amazed at the size of the engine! I had already overhauled the tilt steering column just so I could start it. Then the gas tank decided to start leaking, so that launched me into take apart mode! lol


I've actually had it down this far a week or so ago~ I'm having a time getting the shift knobs off to remove the ugly shift boots. . Still amazes me that an upgrade to the dash is to install a cj5 metal dash? Not going there as like the original.

 

Not sure if the knobs are similar to a TJ, remove the shift pattern from the center , should be a nut underneath.

 

THank you! I'll check that out soon!

 

Since the tropical storm is soon to be here, I had some time to work on the JJ (jurassic jeep). It developed a leak from the plastic gas tank, so I knew I wanted to get the tub off, that helped with the gas tank removal. The tub wasn't to difficult to get off.
I'll gut the rest of the tub gutted in a few weeks and then install on the rotisserie The body's not in to bad of shape and may just sand it well and address the areas of rust as needed, but I would like the frame blasted.


The high/low lever wasn't even connected; has some kind of weird way that it connects to its square actuator thing. Still undecided on whether or not to have the engine overhauled, but I'll put it on the engine stand soon enough~ have to pull the exhaust manifold due to the crack anyway. I'll get a cost of the overhaul anyways. It has some kind of vacuum switch to activate 4WD, I read that it causes some problems, but I'm not terribly concerned about having 4 wd, but want it would be nice to have it work.
The 4.0 is pretty nasty as the rest of the under carriage, but that's just labor to make it look nice! A new exhaust system really isn't too pricey so I will replace it all.
I did at least get to drive it back from the PO and it shifted well, so at least a new clutch will be in order.


It's a plastic gas tank with a metal protector/skid plate underneath. Someone had to have had the gas tank out in the past due to the installation of a home made trailer hitch. I'll be going back with "bumperettes"

 

I dropped the gas tank of my YJ in a church parking lot one time. Reason was the pavement was brand new and easy to work on. A member of the staff drove by, rolled down his window, asked if everything was ok and was blown away to see a gas tank sitting in the parking lot. They know me by name there now.

 

I think the tank may have been easier to remove if I had removed the exhaust hanger and been able to push the pipe away from the gas tank shield. then both support bands nuts were seized. There was an amazing amount of crap/dirt/rocks in the tank protector. lol A peculiar thing, there are two vents atop the tank and the rubber which holds those in the tank were 'melted', kind of gooey. I hope the new tank comes with those. I think there is a gas tank kit which has everything(straps, fuel pump, etc), but I'm a ways from thinking about that for now. I don't think the fuel filter has ever been changed!

Kids n grandkids are here until Thursday due to the tropical storm. So really not much will get done, but I would like to clean and organize again~ amazing how cluttered it gets!

 

I had some time today to put the tub on the rotisserie~ kids will be going home Friday so I should be able to get back playing again

 

it's what shifts the disconnect in front axle
there's a aftermarket push/pull cable you could buy

 

I like this Square headlamp project you have, even if the YJ is hated I loved mine. The transmission shift knob has a metal collar threaded underneath it. It has 2 flat spots, throw an adjustable wrench, or the right size wrench and loosen the Jamb spacer. Then thread your shift knob off. I had a 94 YJ for 8 years. I may be able to answer other questions too. I loved that Jeep. It's the classic "never shoulda sold it". story

If you peel your Shift pattern off there won't be a nut under there and you will have to glue your pattern back on I'm sure the other poster meant well, and he is right that the TJ is that way.

My 94-

 

You can replace the cad axle with a XJ(Cherokee) axle shaft and eliminate the vacuum/cable options. I've only installed this with selectable lockers/open diff's. Ron

 

Thank you and that is a nice looking jeep!!

 

Thank you, I'm not there yet, but you can help me when I come to that part

 

what ever I can do

 

Today I rolled the tub out on the rotisserie, got it down as far as I think I need to go as far as bolt on stuff is concerned. I pressure washed the entire thing. The bottom has an undercoating of sorts, not thick. I'm thinking to just go ahead and do body work, fix broken bolts, repair rusted through areas, etc. I guess what I'm saying is that I think I can get away from having it sandblasted, however, I do want the frame blasted and be squeaky clean.

I have the hood on a stand, and started playing with this~ I'm going to look for another hood and both front fenders are messed up too. But before looking for "used" parts, I'll play with the idea of cutting the damaged metal on the hood and weld in new metal. I did something similar on my Triumph TR6 hood. I tried peeling the metal back out, but that just doesn't work. There's a jeep guy in Houston which has parts and I'll ask him for a price for what I mentioned, that may make me try harder to fix what I have ! lol

 

Orrrrr..... since you're going for a Jurassic Park theme, make it look like a dinosaur bite???

 

I would second getting rid of the axle disconnect. Swap in a non CAD housing. I don't know if it's the salt, Pennsylvania people beating their stuff or what but axle disconnect woes seem pretty prevalent around here, especially once snow season hits. They even seem to bend at the disconnect area of the housing. I personally think it's the Jeep rejecting it like a human body rejects a bad organ.

 

Removal of the engine wasn't too bad, I've decided to have it overhauled~ too much work involved NOT to It actually doesn't look too nasty in the rocker arm assembly. I have a decent engine stand, but with that much weight, it's incredible it doesn't collapse! I did put a 2x4 under the balancer, but I'll be taking to the machine shop this week.




The engine is just plain filthy! I may disassemble the intake and let the machine shop boil it~ however it's aluminum; not sure if that's be a good idea or not. You guys know I like a clean n pretty engine

Well, the seller said it has a new clutch, I didn't believe him as the bolts just look like they've never been out of the transmission, but the pressure plate and clutch assembly was very clean, marks still on the clutch disc. I'll leave that alone. I guess I could have the flywheel machined, but when I drove it, it had a smooth action when shifting, so I may not, lol.


nasty


I'll be replacing this when I find out what to buy.



I'm thinkin to put the frame on the rotisserie with the axles included. Remove all the lines, brake drums/disc and calipers, remove the power steering and complete steering. I will be getting new springs and probably steering.





I was able to save the hood and fenders, wasn't as bad as I thought, since this pic I have welded the sheet metal into place and body filled it, still have a lot of work ahead, but it's pretty much smooth sailing so far




I'll be back!!

 

Hi guys! The weather has been incredible! cool mornings~ ahhhh

I've just have the frame down to its birthday suit The bolts on the rear; one nearest the middle do not want to budge! I cut the front ones out with a cutoff wheel and that worked very well!
I guess I'll go ahead and have the frame blasted~ why not do a jam up job! I have springs ordered, nothin special, but new.

To wrap up the day, I pressure washed the frame again, the transmission/transfer case, and the rear differential; then put tools away.

Tomorrow I really need to get back on the '68 , I tell ya, I've been having such a great time tearing down the '92! It was so neglected


The front wheels have these spacers, but not the rear? Why do they put these on?


This is probably the reason the wheels were locked up in the front~ when I pulled the rotor off it was packed with this dusty rocky mud


I took the long block to the engine builder yesterday. After I had striped the engine, there's this pin in the bolt which holds the timing gear in place; it kind of rides on the timing cover~ I'll put it back, but why?


A last question~ the front sway bar? is it absolutely necessary? It's a crazy heavy thing
dne'

 

There should be a reinforcement plate on the inside of the timing cover, It's used to keep the cam shaft from walking. I don't run a sway bar on my YJ, I didn't notice the body roll till the springs had some miles on them. Ron

 

Some of the reasons for spacers on only one axle: If one axle is narrower than the other.
If it had non stock wheels with incorrect backspacing maybe to provide clearance for the disk brakes.
Or if it had oversize tires to prevent rubbing when turning.

Yours doesn't appear to be either one of the first two, at least to my eyes. And the tires in the first picture don't look really large, although that would be my guess. In the picture early in this thread the front tires do appear to be sticking out further from the fender flares than the rear tires, but it's a little difficult to be sure with the side angle. I'm sure others may have some additional thoughts. Your project is looking good!
