Wrenching advice

Last weekend, I replaced my clutch. I hope that I won't have to do it again fir a while, but is there any advice you guys could give me to make this easier (specifically sliding the tranny and t-case back in place). I had 4 guys helping; one operating the floor jack (near the back of the T-Case), one ballancing the T-Case/Tranny near the rear output yolk, and two guys at the front of the Tranny to line it up and slide in place. The whole time, I was thinking that "there's got to be an easier way". Any advice would be appreciated.

LOL, I could be an a** and say "Yeah, get a lift and a tranny lift, and it'll be easy", but i won't do that.

I'm a backyard do-it-yourselfer also. I just did the clutch in my '77 CJ-7, and installed my old T-18A/Dana 20 combo with skidplate. Having done it on my old jeep 3 times previously in a stone driveway with a regular floor jack, I said "this is gonna suck"!

Here's the trick: borrow (if you can) or rent a Tranny Jack. It is a wide stance, low to the ground Floor Jack type Chassis, but it has a large adjustable support plate with tie-downs. The support plate also has knobs to tilt the entire assembly forward, backward, and side-to-side, once the assembly is all tied down.

I hoisted my assembly on my garage beam, then lowered it onto the tranny jack plate, and tied it real well with thin rope, before taking the weight off the beam. Then you can move it around one person very easily. I did the job with only one friend helping this time (as opposed to 4, like you, LOL). It was easy as hell this time, the toughest part is always getting the shaft splines to mesh and getting the tranny to go in the last inch.

This time, I wiggled it so I had 2 threads on one of the large studs, then pulled it in slowly with the nut until i could get all the other bolts in, then gradually worked around, tightening a little at a time until it was tight. Worked great, easiest Jeep Tranny Job ever, so far!

The key is the TRANNY JACK, worth it's weight in gold! <img border="0" title="" alt="[Wink]" src="wink.gif" />

When I did my T5 and Dana 300 a couple weeks ago I separated the tranny and transfer case. then I manually lifted the tranny into place and got the bolts caught then snugged the whole thing up. then I put the transfer case on a floor jack, lifted it up where it needed to be, caught the splines and released the jack. the case rotated until the holes lined up and that was in too. This method worked for me, with a T5. I wouldn't reccomend it for any of the other trannys.

LOL, West,

I'm glad you said that about not doing it with the other trannies, LOL <img border="0" title="" alt="[Wink]" src="wink.gif" />

Definitely wouldn't recommend that with any cast iron case, LOL, the Bellhousings are very weak in that direction of stress, LOL.

How did you get your skidplate in after? Have to have a floor jack under the front of the tranny to hold it up, then slap the crossmember up?

Yeah that's how I used to do Mustang T5s even in a tranny shop with car on a lift. somehow the jeep T5 felt heavier. Maybe I'm getting weak. Yes I used a floor jack under tranny and muscled the crossmember into place, a little awkward but it worked for me. Now if I can get it to shift right I'll be happy.

LOL, I know how you feel, I think sometimes I am getting weak, too, thinking back at some of the things I used to do without jacks, LOL! <img border="0" title="" alt="[Eek!]" src="eek.gif" />

You guys are gonna laugh at me but here is a trick that works really well. Pull the motor! We used to do this with early Broncos because the transfer case linkages were such a pain to work with. Knocks about an hour off the job, and you don't have to try to line anything up up side down on your back with dirt in your eyes.All you need is a come-a-long and a big Oak limb.

I can't see how pulling the motor would knock and hour off the job. There's so many additional things to disconnect and reconnect.

LOL, although pulling the motor is not a hard job, it will most certainly not knock time off the job, as long as you have a tranny jack on a flat surface, LOL.

TC-linkage on a Jeep is nothing, all I had to do was take one bolt out, and lay the TC shift lever flat, didn't even have to disconnect the linkage at all.

The T-18A is by far the worst tranny to re-install, due to it's sheer hulkiness, and it only took me about 20 minutes to drop start to finish (that's the easy part, tho ), and putting it in took me about 2 hours. The 2 hours included hoisting the tranny, securing it on the tranny jack well (I spent time on that, so the rest would be easy), sliding it in, and bolting everything back up. I don't think that's bad for backyard mechanics.

The key, and I really am serious, is having the tranny jack. I borrowed mine from the Town Garage, but I'm sure it is very cheap to rent one for a half-day (and well-worth it). You won't believe how much easier it is until you try it. Instead of fighting to balance the damn tranny side-to-side, while holding it on a floor jack, you simply use all your effort simply sliding it into place. The hardest part is just getting the last 1" in place, because the shafts are so tight-fitiing. Once you get some threads, and are sure it's lined up, you simply "pull" it in place with the bolts a little at a time.

I told you guys you would laugh at me. But you know what, LAUGH ON! I've done it both ways and I will never pull a tranny again.It takes about an hour to disconect everything(if the exhaust cooperates) and winch the motor out. You can drop the bellhousing and cluch/flywheel with the engine hanging. Of course the newer the Jeep the more complicated the engine bay becomes.I'm sure with AC and cruise and all the other bolt on goodies on the later model Jeeps this may not be the way.But if you have an earlier model with minimial junk you should try it. I think you'll be suprised.
