Help With T18 Id

Good morning,

Hoping for some of your expertise on this one. I have a T18 with bell housing and D20 from a parted out 1977 CJ5. VIN was (J7F83AExxxxxxxx) which I think says 3-speed though?

Specs are:
Tag # on cover 5358092 and 13-01-187
Also marked with 13-01-097-9071 or 9077 as it's hard to read.
No adapter between the trans and bell housing but an approx 1" adapter between the trans and Dana 20. Shaft sticks out a little over 7 inches.

I've counted the splines and turned it by hand in 1st gear and it's definitely 6.32-1. This leads me to believe it's one of the more rare 1977-79 factory T18s but the VIN says otherwise. Obviously it's always possible that a previous owner swapped it in using factory parts.

I've read that this will bolt up to my 304 with a new clutch and pilot bushing? I know I'll have to move the crossmember and change driveshafts etc. Also, it's hard to find the front and rear seal numbers for replacements. Everything seems to focus on the Ford T18s.

I'll post some pics as soon as i can get them uploaded. Thanks for the help in advance.

5358092 is T18 from 1977/1978 CJ series.

 

This is what i have. Thanks

 

Very desirable transmission. Finding a bell might be tough, but you have one. Good deal!

 

So just to verify, will this bell housing not bolt up to a 304? I've searched a ton but there is so much conflicting info out there that it makes my head spin.

Thanks

 

PN on the bell? Yes it should. No difference between a 232, 258 and 304 bell for this app.

Less than certain it's actually conflicting data. This application changes from year to year in the '70s.

 

I'll look when i get home today on the bell. Thank you Sir.

 

That bell housing will bolt to 232/258, 304/360/401.

 

Great news on the bell. I’m about to grab a clutch for it. I’ll order the clutch based on the trans and then just need a different pilot bushing for the 304 V8 is my understanding? Also, anyone have a preference for the diaphragm vs other kind of clutch? Sorry for so many questions but all the info I find on the search is geared towards the Ford T18. Thanks for the help guys.

 

My opinion. Dont get a 3 finger borg and beck style clutch. Get any run of the mill parts store diaphragm clutch and try to find a usa made timken throwout bearing. Or a federal mogul throwout bearing. I like the duralast clutches autozone sells but I do not use their bearing.

 

Ok thanks for the info

 

The aftermarket sellers offer both the Borg&Beck style (3 fingers) and diaphragm style (lots of fingers). The diaphragm style is said to require less pedal pressure to release. The sixes and the 304 came with a 10.5" clutch, and the 360/401 came with an 11" clutch (always Borg&Beck that I've seen). The 11" clutch will fit a 304, but may need too much leg force to be comfortable.

All the throw-out bearing numbers should make sense. Match the bearing to the clutch type - they are different for B&B and diaphragm. The pilot bushing may be tougher; if you need to, go to the listings for a '71-72 J-truck with the 304 and T-18 and pick that pilot bushing.

 

Thank you very much for the info, much appreciated.

 

The pilot bushing should be the same as a ‘76-‘79 CJ with T-150 3 speed transmission as the pilot on the input shaft is the same diameter and the bell housing depth and input length is the same. You should be able to order it by the T-18 application however.

 

Great info, thank you very much
