T18 Swap Episode 3 - Pry it Out, Shoehorn it In

{fade in while dollying up the driveway toward a Jeep up on 4 jackstands with a rebuilt T18 sitting behind the left rear wheel}


As with other episodes of this story I welcome comments, suggestions, and derision (along with laughter where you feel the need).

I guess episode 2 and 3 will proceed at the same time. I got stuck on the Dana 20 rebuild so I decided to remove the T15 and Dana 20 from the jeep while I had the weekend downtime.

A slight prequel: The Hi-Lift jack is man's greatest gift to Jeepers! Using my floor jack I run out of travel with the tires 1" off the ground. With the high lift I got 6" under all 4 wheels and could have gone higher, but wanted to leave clearance for the garage door to open. Jackstands on all 4 corners for safety, of course.

Front shaft off. OMG!! the U-Joints are TOAST [img]images/graemlins/thud.gif[/img] Oh well they are being replaced anyway.

Using Leve's (and others) suggestion I placed a ladder across the rollbar and windshield and looped some ratchet straps from the ladder under the transmission. Snugged up the straps to take the load off and proceeded to take off the frame cross member. There are rocks and sand from 28 years of the Jeep's life embedded in there, almost feels like I am disturbing an archeological site or something [img]images/graemlins/blush.gif[/img].

Bottle jack and a bunch of 2X4 blocks to support the rear of the engine and out with the transmission attach bolts. Off with the shift assembly from the top of the transmission. (I should have removed the Tcase shifter as well, but live and learn [img]images/graemlins/confused.gif[/img]) Started lowering away and sliding back with a dolly in place to catch the Tranny/Tcase combo and sure enough the shifter hangs up [img]images/graemlins/cussing.gif[/img] Finally found an angle that I could work it out of there by taking off the shift knob, but would have slipped out easy if the shifter was off. The 2" drop and loud thud once the handle cleared made me glad that I was off to the side. Important safety tip: NEVER be under something that is hanging from a strap or on a jack. Jackstands or ramps are the only thing that can be relied on.

Anyway, separated the Dana 20 and placed it on the bench with the other one. Then I parked the 3spd behind the Jeep.

Enough for one session, more on episode 3 as it proceeds...

Re: T18 Swap Episode 3 - Pry it Out, Shoehorn it In

Update 2-9-04:

Question for the experienced wrenchers out there: Is there some fancy articulated socket extension or do you drop the engine/raise the body when removing a bellhousing?

Todays accomplishments were remove starter, bellhousing, clutch assembly, and pilot bearing. Out of 4 hours spent putzing around with the beast 3:15 were involved in the 6 or so bolts of the bellhousing. I was in every position imaginable except hanging from my ankles (that would have been an improvement). The 2 top bolts were a grade-a 24K beotch to get out. I finally ended up sitting indian style between the dual exhausts with my head poking part way out of the transmission hole and working the bolts out with a u-jointed extension and a socket wrench [img]images/graemlins/tongue.gif[/img] Thank goodness nobody was around to take pictures [img]images/graemlins/smile.gif[/img].

Anyway any day that shows progress is a good day [img]images/graemlins/40BEER.gif[/img] The clutch disk is quite glazed (75k miles), so it is just as well that it is getting replaced. I can't believe that I was thinking of keeping the existing clutch [img]images/graemlins/spank.gif[/img]

Tomorrow I will be off to Fasson's (local 4X4 place) again for a '76 clutch kit (need the 1-1/16 10 spline since my T18 has a ford input shaft). Still got to get the flywheel off for resurfacing. Thanks to all who advised me on that. I SURE don't want to skip a step now that I am so far into this.

the saga continues. . .

Re: T18 Swap Episode 3 - Pry it Out, Shoehorn it In

I know those bolts well. I've pulled mine so many times I can hit those bolts blindfolded. I usually let almost all the weight of the tranny pull (tilt) the engine back away from the tub and hit the drivers side from underneath using a 12" extension and the passenger side from the hole in the tub for the transfer case shifter with a 6" extension. When pulling the tranny take those out first and when installing the tranny put them in last. Make sure you have and use the spline alignment tool when reinstalling. You may need to loosen your motor mounts but do that at your own risk, I don't know enough about it to tell you it's a good idea. I did it the first few times.
Also, a trick that a friend taught me - put some grade 8 studs in, in place of the bolts on the sides. It will greatly aid you in lining up the bellhousing. Do it the FIRST time you remove the tranny. Don't think "oh, I'll only do this once, it's not worth going to the store to get the studs" When I did my T-18 swap, I thought every time I reinstalled that damn thing it was the last time, all ten times.

Good Luck!

Re: T18 Swap Episode 3 - Pry it Out, Shoehorn it In

Thanks for the tip Aaron [img]images/graemlins/goodpost.gif[/img]

Well the flywheel is off and at the machine shop for resurface. There being nothing more to take off the Jeep, the next post will be the beginning of the reinstall phase.

Question: Should I wait until the Tcase is rebuilt and install the Transmission/Tcase together or is it ok to put the transmission in now and Tcase later?

Question 2: The T-176 bellhousing I have has 3/8 holes and the T18 was bolted on with 1/2" bolts to the FSJ housing. Should I drill out and tap for 1/2" bolts or use busings, or just put the 3/8 in and not worry about the extra room around the bolt shaft?

I am leaning towards drill and tap for 1/2".

Better make sure they don't have any slop, sleve it or tap it or something. Mine is through bolted w/ 5/8" fine thread bolts and who ever did that to it originaly (jeepgod) was a dumbass.
I've installed both ways and I think it is slightly easier to install them together as one unit.

Tomorrow I will be off to Fasson's (local 4X4 place) again

[/ QUOTE ]

Hey I know that place... out there on County Line road between Plant City and Lakeland. I'm originally from Plant City, grew up just off SR60. My Dad took me to Fasson's, said back when he was young and building Jeeps like I am now, Fasson's was tha only place around that you could get anything. we just happened by there and he was shocked to see them still open, so we swung in. I was in heaven looking at all the crap he has around there!

Brent: I actually went there based on your mention of the place in one of my other threads.

Hehe looking around Fasson's "showroom" (buncha parts laying around and randomly stocked on dusty shelves) there may be some of the same things in there that you were looking at back in the day [img]images/graemlins/grin.gif[/img]

But it is a great place to get parts!!! I walked in with an 80's bellhousing and asked for a clutch boot and the guy walked in the back and came out with one in his hand [img]images/graemlins/shocked.gif[/img]

The bonus is: you can get information/advice with your parts. I got many good tips on the T18 rebuild (they do them there) and the Dana 20 rebuild.
