Hi folks, I know I saw it before but I cannot find it now. What clutch/flywheel do I need?
Specs:
98 3.4, R150, using the 3.0 bellhousing
do I need the 3.0 flywheel? the throw-out bearing? Is it a mix-n-match for the clutch disc/pressure plate?

I had thought it was 3.4 flywheel n clutch, but with the 3.0 TOB inside the 3.0 bellhousing.

Now I have forgotten, and I am really lost... which sucks because I am aiming to stab the engine and trans in my truck this weekend.

The memory fades with age...

There are various opinions, but the general consensus is:

- 3.4 flywheel, 3.4 clutch disk, 3.4 pressure plate, 3.0 throwout bearing
or
- 3.0 flywheel, 3.0 clutch disk, 3.0 pressure plate, 3.0 throwout bearing

The 3.4 flywheel/clutch is slightly larger than that of the 3.0, not sure if it actually makes a real-world difference, but I went with the 3.4 parts.

You will have to use the 3.0 throwout bearing, it must match the input shaft; the 3.4s and 3.0s have a slightly different input shaft length.

The pilot bearing for 3.0 and 3.4 are the same (as well as the 22RE and a host of others), so the actual application isn't too important.

The other consideration is the starter. I was under the impression that the starter had to match the flywheel (ie 3.4 starter with a 3.4 flywheel or 3.0 starter with 3.0 flywheel), but there have been a few people that have successfully mixed and matched parts successfully (ie 3.0 starter with 3.4 flywheel, or vice versa).

Thanks, that's exactly what I was looking for.

I got the 3.0 BH and went to get the 3.0 TOB; but it was way shorter than the 3.4's... like an inch shorter. So I was scared and ended up getting the 3.4 TOB since it matches the trans/engine/flywheel I'll be using.

Here's what I'm going with:
3.4 clutch set/flyweel
3.4 TOB
3.0 BH

Again, this engine/trans was pulled from a 98 Tacoma; I picked up the whole wrecked truck for this swap. Front hit, heavy frame damage, but it ran and drove onto the trailer just fine.

Well, that was a wasted afternoon. The 3.4 TOB is too tall (yeah, you told me... ) so I got a 3.0 version.

Get the engine mated to the transmixer, and it looks like the 3.4 clutch fork is now preventing everything from fully seating properly.

Last week I saw a few 3.0s at the yard; some had the engines removed, so the tasty clutch forks were in plain sight and easy to get to. I'll try and get one tomorrow, stick it in the mix, and see what happens.

I had briefly thought about modifying the 3.4's fork, but figured I'd waste more time figuring out that compared to just getting a 3.0 fork.

The saga continues...

Sorry I wasn't able to respond sooner and save you some time. As you know know, you want the throwout bearing to match the bellhousing and transmission input shaft. And now that I type that out, you may need to swap the transmission input shafts to use the 3.0 shaft that is the correct length, but I honestly don't know, that's further than I've had to explore.

Good luck

Edit:

You're right; the shafts are about 1" different... I sure as hell am not swapping inputs at this stage of the swap.

Mods, you can delete this thread since it was a waste of time.

Dammit.

So whats the update? How did it turn out
