2.9 and 2.8 flywheels and clutches?

Hmm, that makes a bit of a difference.... an FM145 is two inches too short and you're going to be doing quite a lot of work to cram that in there.

The transfer case should work fine. But the shift lever won't. It was meant for a case mounted two inches further forward, so it's going to hit your dashboard.

couldn't the clearance/function issues be overcome by using the t-case shifter and linkages (including the are from the tcase) that came with the tranny being installed. and perhaps opening up the hole in the floor.

I got the interference backwards... it may hit the seat, and the boot may not like it much.

Got my clutch/brake pedal assy today and now I have a heck of a kink in my neck from laying under the dash in mud and rain. Still need bellhousing bolts, clutch master and fluid line.

The M5R1 is the tranny that I'm going to use with the 1350 manual tcase to replace my A4LD and electric 1350 tcase. Unfortunately, I don't have the tcase shifter and mount for it. What floorplate and boots should I look for? I didn't find an M5R1 with manual tcase today.

nate you should use the flywheel,clutch and starter from a 4.0l to get a 10" clutch.you need the positive battery cable and jumper harness from the fenderwell relay down to the starter from the donor truck to make it easy.the shift linkage is very similar on the two tcases you can probably get it to fit the m5od.you will probably need the boot and floor plate from a m5od/manual shift truck. fm-146 stuff might work since the trannies are the same length but the shifters come out of the tranny at different spots.

Tryin to keep costs down, this is alrady costing me more than it was supposed to. I think I'll be fine with 2.9 clutch and 235/75R 15s.

Actually the T-case shifter will be in exactly the same place relative
to the driver, but the "arm" that works the T-case will be the wrong length.

There is no "linkage" with any of the RBV T-cases.

I have the manual tcase shifter from my fm145 tranny...will that work with my M5R1?

 

[rickcdewitt]

only if the mounting boss on the m5od is in the same spot as the fm-145.the one with the large pivot bolt and small shifter gate bolt

 

[Natedog]

Don't know yet, won't have the tranny untill next week hopefully.

Called auto parts store yesterday and the clutch master, fluid line, and slave cylinder are different for 1987 and 1991. The 1991 for 2.9 and 4.0 are supposedly the same clutch parts. I think I need to use the clutch, clutch master, QD fluid line and slave cylinder for the 1991, is this correct?

as far as i know theres only one part # for slave cylinder on rbvs.the clutch should be specific to the engine not year model also.the 88 i had is the same master as my 91,i don't know about 87 though.your stock clutch line should plug into the new(reccomended)hydralic throw out cylinder

FWIW worth Ive seen 2.9s with the pilot bearing in the crank and the flywheel.

You'd think so, but that's not what the local parts yo yos told me...lol. I have not stock clutch line because it was an automatic, so I have to buy a hose too. I'm lookin at the 1991 because it's 2.9, M5R1, and has the QD clutch line.

you are probably right,allan d was saying in the recent thread"slave cylinder 2.9l vs 3.0l on post #4 which years have what style,you probably woulden't go wrong with the same year stuff as the tranny(91-92 2.9lm5od)its a good idea to ask allen d.i like the QD because you don't need to bleed it when you take it apart i wish my 91 2.9l had an m5od-r1 behind it,i rebuilt my fm146 before i knew about the swap.
my thought on the shifter is cut off and reweld or redrill the phlange that holds the shifter(large pivot bolt,small bolt) if the m5od has it in another spot

 

[Natedog]

My reconditioned flywheel has about 1.125" hole for the pilot bearing...but the pilot bearing in the clutch kit for a 1991 has needle pilot bearing that is about 0.625" OD...what do I need to buy? DOn't have my old flywheel and don't remember what size the hole was in it, but thinikin it was smaller like the pilot bearing that I bought. My 1987 manual seems to show two different sizes of pilot bearings and one is in like a sleeve with a shoulder so that it can only go in the flywheel one way. Also what size are the clutch pressur plate bolts supposed to be?
