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

Ya, last time was there he had a few trannies on the shelf, rebuilt and ready to roll. I was in the market for a replacement T-150 at the time, and I thought he was out of his mind when he wanted $500 plus a core [img]images/graemlins/shocked.gif[/img] for T-150!!!!????

I've been wanting go out back and look at his axles, look slike he keeps or kept a good supply in stock.

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

Progress 2-22-04:

Well, the bellhousing is drilled and tapped. The top 2 holes are 7/16 coarse. I drilled the bottom right and tapped for 7/16 coarse. The bottom left I drilled to 7/16 and shoved a bolt through from the clutch side of the bellhousing. (see pic). On the inside of the bellhousing there is a ridge right next to the hole that will hold the head of the bolt still while it is tightened. Fingers crossed that it will work that way.



The bellhousing fit right on, but the [img]images/graemlins/cussing.gif[/img] clutch fork rubs on the inframe header on the driver side. This was not a problem with the old bellhousing since it was longer and positioned the clutch fork further back. I actually went inside and looked up the prices for a driverside stock header and exhaust pipe [img]images/graemlins/mad.gif[/img]. Common sense prevailed and after taking another look I saw that a little grinder work would fix it. So Grind, Fit, Grind, Fit, Grind, Fit, aha! it fits! See pic also (same pic) for grinding on clutch fork (kind of edge on in the pic, the edge facing the camera has been ground).

I did some measurements and the mount holes on the transmission adaptor will be further back than with the T15. It just lines up between the next set of holes in the frame, so my next job is to move the crossmember hangers back. Oh boy! more 30 year old bolts to take out [img]images/graemlins/thud.gif[/img]

So, the bellhousing is back on and the tranny/tcase combo is ready to be installed. The twinsticks will be here Thursday so I should be done this weekend (yeah right! this is a Jeep project, so who knows?)

Progress 3-1-04:

The twin sticks arrived. Not much to look at, but they should do the job. A little additional fab needed to link to the FSJ D20. I will post pics of the twin stick as I get it set up.

I made a platform for my floor jack. Basically a piece of 1" crate wood that was laying around with a 7/16 bolt holding it onto the jack arm. Heave Ho the trans/tcase onto the board and block it up so it is basically level.

I had to jack the jeep real high to clear the shift tower (shifter is out) and then let it back down so that my jack can get the transmission high enough to mate to the bellhousing. It ended up with the wheels back on the ground for the first time in a month or so. Still gotta love the hi-lift [img]images/graemlins/smile.gif[/img]. One note of caution on Hi Lift usage: when the instructions say never have your head between the handle and the upright, believe it! I was letting a corner of the jeep down and the handle slipped out of my hand, bounced at the bottom of the travel and then was pushed up by the weight of the jeep [img]images/graemlins/shocked.gif[/img] It clipped me on the cheek enough to know I was lucky. If my head had been 2" closer I would have gotten a major smack.

Anyway, now that the transmission is between the rails, I find out that I don't have enough clearance without removing both mufflers and pipes. They will fit after the tranny is installed, just not room enough for it to be back 8" from its final spot and then slide forward. Oh well, if it was easy I would be done by now [img]images/graemlins/tongue.gif[/img]

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

I don't mean to laugh, but I am. I did the exact same thing when I swapped in my T18!! Only difference was, the sucker knock my butt out for a few minutes. Stagger back upstairs and sat on the kitchen floor with an ice pack. My room mate comes out and says, "Geez! Do you want me to take you to the hospital?" My response? Naw, just give me a minute. That biatch is going in today!

Keep at it man, your almost home!

[img]images/graemlins/confused.gif[/img] 1" BODY LIFT REQ'D TO SWAP IN T-18 to CJ??? [img]images/graemlins/confused.gif[/img]

I'm intending to swap a T-18 into my Scrambler in the near future - sandwiched between a 258 or Stroker and D300.

For some reason - cannot remember where I saw/read it - I've got the idea that swapping in a T-18 requires a 1" body lift. Is that right?

Just to apply some logical thinking: The T-18 was a stock transmission. There was no body lift stock.

Definitely not. My CJ7 was completely stock before the T18 went in. It fit perfectly and all I needed was the adapter from it to the Dana 300. Didn't even have to do anything to the drive shafts. The only "modification" you haave to do it the tunnel cover. You will need to cut a new hole in it as the shift lever is to the back where as the T5 I had was to the front.

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

Riffraff: It is ok to laugh, I deserve it [img]images/graemlins/smile.gif[/img]

UPdate:

The T18/D20 are attached at the bellhousing! Holding it up temporarily with a jackstand and a 2X4, but It is IN!

Next to finagle the crossmember and tranny mount. Any ideas? Will the stock mount go onto the adapter plate holes?

I have already moved back one set of holes on the frame, so hopefully everything will fit.

The rear shaft is too long, took it to local shop for adjustment. Needs to be 16.5 inches running length (center of u-joint to center of u-joint. I am hoping the front shaft can stretch a little and save me the headache and expense of front shaft lengthening.

I hate it for you, but mine had to be lenghtened.
My rear is 16.25 and my front is 34
