lots of sm465 questions. please help!

The T-14 in my jeep is on its way out, it grinds almost every time upshifting into 2nd, and forget downshifting. Im having trouble finding master rebuild kits for the t-14. anyone know who has ones that have synchro assemblies bearings, seals, snap rings etc etc??

anyway there are a bunch of sm465's around me that i could get for a good price and i was wondering whats all involved in putting this in.

I have a 225 v6 in my jeep, and i have both style bellhousings, the early one, and the one that came on the 71's, which one would i need for the 465? will i have to order an adapter plate?

Im guessing my clutch will still work, but what clutch fork/throwout bearing must I use? new input bearing retainer??
will i still be able to retain the factory cable linkage?

the adapter to the d-18 is a given

which 4 speed is cheaper to get in an old cj5? a 465 or a t-18? the t-18 probably would be better becuse its smaller but then i would have to change the input shaft and make an adapter to my bellhousing.
I figured the 465 but what do i know ive never done the swap before. thanks guys!

 

You would use the earlier bell housing but it needs to be bored out then it is a direct bolt up. I would be happy to do it for you I have done several.
Then you need to decide if you want to use an adapter from Novak or Advance Adapters both of witch I believe require a full main shaft replacement orshould the Novak I know does but Avanced I am not sure.
Both adapters are over 400 dollars but well worth it.
Clutch and all should still work fine you will need to move the crossmember a bit as well.

 

Lots of info when you search the forum for sm465.

Hey *******, I'm doing the 465 swap, and have all the peices, just no time at present. If you want a run down here some time and look at what I got. give me a ring. T18 is smaller, I think cost and etc is going th be about the same on both. The T18 was a great swap, a little screwing around with finding the right clutch etc, but has worked great for 10? years now. I think if I where doing it again I'd stick with the T18, Just because its smaller and fit in so nice, but it's not really fare, because I havent compleated the sm465 swap yet. I have a lot of info on both if you wana look through it. If I where you I wouldn't waste any more time with that t14, save up and swap in a truck 4 speed. One of the best mods. I did.

 

Herm should have the kit you want for the T-14.

Fixing a T14 is throwing good money after bad, IMO. If a 232 I-6 can wear out a tranny it isn't worth fixing.

My Pop adapted a D20 to an SM465 and had to move his xfer case shifter outboard (simple fab work) to clear the tranny case. Can't comment on splicing to the engine because he used Chevy engine, bellhousing, and tranny and adapted the whole shebang onto the D20.

hey seth, do you have any extra sm465's laying around?i would love to some up somtime and check out everything i need to make it work. are you gunna use the cable linkage for the clutch

 

rebuildin gthe t14 is about a 3 hour job once the transmission is out of the jeep. The kit is available from Herm, or 4wd hardware. it will run about $100.


To adapt the sm465 you will need the earlier style bellhousing not the 71 style. You will need to enlarge the hole in the bellhousing as mentioned above to 5.000". Novak's adapter is a 1" thick plate and a new main shaft that requires complete disassembly and reassembly of the transmission . The advance adapters unit is a spud shaft and a 3.5" adapter. The novak kit is the better choice as it leaves the rear drive shaft longer. However you will need to order 3 new iron bushings for the Novak shaft. You will need a hydraulic press to put these on and to remove the olds one you will need the press and a bearing seperator. You will also need to do some grinding on the side of the case to fit the transfercase. You can use your stock clutch along with the stock cable to activate it.
Don't get me wrong here the sm465 is awesome but it will also cost about $600 total for the adapter and parts along with quite a bit of fab work plus the transmission. The crossmember will need to be moved and lowered along with the driveshafts altered, the sheet metal in the floor trimmed and altered also. It is a beast in size compared to all other 4 speeds and it is not a simple task to tear the transmision apart to put in the shaft especially if you have never torn a transmssion apart.
Here are a few pics to help:
The 1st pic shows the gear cluster minus a few gears, you can see 1 of the iron bushings that need to be removed on the left of the shaft. The 2nd picture is of the 1st gear showing its shear size, the 3rd is fully assembled with a dana 18 hanging off the back, this gives you a real idea about how big the transmission is.

Good Luck with what ever you decide!!

 

I didn't use a hydraulic press. I just heated the bushings in the oven and put the main shaft in the freezer. Then taped them on using the split old bushings as a driver.

 

I did it this way also but it will not work everytime, trust me. Production tolerances will have alot to do with this.

 

I did this conversion and it was well worth the money. I agree that it will change the characterisitcs of you vehicle. Keep in mind this is not a "cheap" conversion.
I used the BOP BH and had a friend machine it. Other things to consider, new clutch, new pilot bushing and new drive lines. I made my own cable for the clutch but ended up going the Advanced Adapters chain route...very happy so far! I also removed the drum parking brake assembly and made a disc set up.
I think all total it ran me around $1500 for the adapter, BH, new clutch, new mounts, disc set up and drive lines. I picked the tranny up for $50 but had to replace the front output shaft due to rust.
I used the oven method for the bushings.

 

sorry *******, no extra 465's but your welcome to come up and see my setup. Nope, no cable, I used the stock torque tube setup on my t18 and had no problems last time. I'm going to use the same setup on the cj6 with heim joints this time and see how that works.

 

I like that picture - it does give an idea of the size ... :lurk:

 

were you able to retain the front bearing retainer on the sm465? or did you need a custom one? will the throwout bearing from my t-14 work with it?

so what i need to do is,
bore out bellhousing.
take apart tranny and ad the adapter, mate the dana 18
drop/ move crosmember
cut out floorpan

did you guys mount the bracket for the cable clutch on the side of the sm465? how did you attach the bracket?

 

I use a hydraulic set up.

i picked up my sm465 today, this thing is a pig!! im going to order the adapter kit soon and bring it to a local transmission shop for them to install it and go over the tranny.

hey green71jeep, seth told me you can machine parts, do you think you would be able to do my bellhousing and front bearing retainer?

 

You bet ya be gald to help out I will PM ya my #.
