I posted this question over in the diesel section but haven't had a response. Thought I would try here. I am putting a 2H engine into my FJ62. I converted my 62 to a 5 speed (H55F) a couple of years ago. So, I want to keep the five speed but am unsure if the 60 series bell housing bolts up to the 2H or do I need to get a new bell housing? Also, will the input shaft and clutch work from the 60? The 2H I am getting does not have a bell housing and it appears that the majority of people just swap the motor and tranny from the diesel into the recipient vehicle. That is not an option for me as the tranny isn't there. Thanks for all your help
 
if the H55 is for the gas engine it will be correct for the H diesel engine. can't help with the bell housing tho.
 
I believe the bellhousing was from a 1986 fj60? It's been about five years ago when I gathered the parts and did the swap. When I look at pictures of a 2H bellhousing it does look a little different from mine. I don't have the motor yet. I'm picking it up in Canada over thanksgiving break or I would just bolt it up and see if it fits.
 
I have a 2h out of a truck on the floor of my shop right now . I'll try to get some measurements and see if an h42 bell will fit tomorrow . It has an h55f on it so I won't be able to test fit but I should be able to determine how close it is or not .
 
Ok so Iv put a H55f behind a 2H. The bolt pattern between the 2F bellhousing, and 2H bellhousings are NOT the same. The only issue mating the 2H to the H55F is that on some of the earlier 2H bellhousings, the portion that mates with the transmission has a little too much material for the transmission to lay flush against it. It can be easily corrected by taking a grinding wheel and gently taking off about 1/16" of material from the inside of the bellhousing "hole" that seats against the transmission. I recomend getting the fitment of the bellhousing and transmission worked out BEFORE you attatch anything to the engine.

As to the clutch components, The flywheel and clutch plates are the same size as the 2F. The 2H flywheel will be a fair bit heavier however, and because the bellhousing is a different shape/length, you will need a 2H specific clutch fork (toyota still makes these as I needed one for my 12HT swap). Your throw-out bearing should be identical. Your 2F slave cylinder will work fine with the new clutch fork.

Any other questions let em fly!

Really?

I know that it is the same on the transmission side, but the 2F has the same bolt pattern as the 2H and 12HT?

2f vs 12ht bellhousing.webp


On the left is the 2F out of the '87 FJ-60 (we put in the H55f), and on the right is the 12HT from the '87 HJ-61 (dirty H55f). Aside from the obvious difference between cast iron (2F) vs. aluminum (12HT), there's nothing I can tell from my pictures, but I have a hard time believing that Toyota would manufacture two wildly different bell housings for two trucks in the same series, produced at the same time.

But it is plausible. Both have the starter in the same spot, and obviously they have the same bolt pattern on the transmission end.

Spot on about everything else though for sure. Clutch, Throwout Bearing, etc....

Great catch dan your right. I was thinking 12Ht vs 2H. Not 2F to 2H. Ill go back and edit.
 
Thanks for the responses! I need to clarify a little bit. I knew the H55F would work with the 2H motor my concern was the spline count and length of the input shaft. are the diesel models the same as the gas? Second, will the 2F bellhousing work on the 2H? from what has been said so far the bellhousing from the 2F is a NO go. Correct? If that is the case does anyone have one laying around that they would be willing to part with? Oh, and it sounds like the clutch is diffrent from the 2H? The clutch I have was fairly new so I was hopeing to be able to use it, but if I need to get one I will. Thanks again for all your help!
 
The H55 with the coarse spline input will work on the 2H, 12H-T and 2F. The H55 with the fine spline input is for the 3B/1HZ, and I am NOT SURE if the same fine spline input is used for the 3B and 1HZ.

As Johnny said, the input shaft spline type and length are the same between 2F and 2H engines. No need to worry there.

The 2F bellhousing will NOT work on the 2H engine. You need a 2H bellhousing.

As to the clutch components, The flywheel and clutch plates are the same size as the 2F. The 2H flywheel will be a fair bit heavier however, and because the bellhousing is a different shape/length, you will need a 2H specific clutch fork (toyota still makes these as I needed one for my 12HT swap). Your throw-out bearing should be identical. Your 2F slave cylinder will work fine with the new clutch fork.

To boil down what I said above ^ : Your clutch plate, and pressure plate will work. So will your throwout bearing and slave cylinder. What will NOT work, is the CLUTCH FORK and FLYWHEEL.
What you need to make the clutch work: New 2H specific clutch fork. You can order these from your toyota dealer.
- 2H flywheel. Its significantly heavier than the 2F flywheel. Its possible to run a 2F flywheel. Mechanically it will function. But because its lighter, its not good for your engine and your clutch will burn out sooner.

Ill try to dig up a picture of the fork your going to need.

The 3B and 1HZ flavors of the H55f both have 21 splines, but have different input shaft lengths.

The 2F, 2H, 12HT (and H, for that matter) are the same as far as the H55f is concerned. Same for the Clutch. In fact, we installed a new clutch on the 2F when we installed the H55f, then we decided to en-awesome the truck, and put in a 12HT. We put the (slightly) used clutch that was behind the 2F onto the 12HT flywheel, used the 12HT/2H bell housing, and bolted everything else back together.

So really, if you have a 2H, and an H55f (with the 10/course spline input shaft) you just need to find a 2H or 12HT bell housing (and flywheel, if you don't have one on the 2H).

I love mud members I've been able to track down a bellhousing and a clutch fork. Now I need to find a flywheel. Anyone got one laying around. 2H flywheel?

I have a similar question regarding putting a 2h into my 1988 FJ62, but I have an automatic transmission. All I would need is different gearing in the transfer case correct? Or would I need an entirely different transfer case?

transfer case is relevant for what you are asking unless you want different gear ratios.
