H55f and 3fe Bell Housing Interference Issue

[tag3]

Mine went in no problem, late 85.

Obviously, not all bellhousings with a 3F on top are the same. In my opinion, the 2F bellhousing is better anyway, because it doesn't tip the transmission 9 degrees to the side like the 3F bellhousing. Grind it and bolt it up. 6 months from now, you'll have forgotten all about it.

Also, though I have a 3F housing, (it had more to do with the HJ61 frame i was using) the slave cylinder is adjustable on the 2F configuration. But, 2F bell housing should really require double cardan drive shafts, not required with the 3F housing (in a mostly stock config)

How the heck did you come up with that?

I"m not a parts guy and don't know if the bellhousings that are stamped 3F have multiple iterations...assuming they do given the present problem.

More likely the double carden shaft was used in FJ60s that had the 2F BH because the spacer was not used between the t-case and tranny. The front shaft in this case is shorter thus the need for the DC joint, or perhaps a combination of having the t-case a little higher plus the shorter t-case to front diff distance.

Also, as Elbert said, there are technically 5 different part numbers for the bell housing during FJ60 production, and some change in just a few months time span.

5 different part numbers to correspond to B, H, 2F, 3F, those 4? And what else?

Negative Jim.

There were 5 different part numbers for 2F bellhousings alone.

Did mine swap in the last two weeks (from Beno, thanks!) . I have a July '85 build with 3F on the BH and it slide right in an bolted up just fine. A heavy SOB but it mated just fine.

I have 3F stamped on my truck's bell housing.

Ok, i believe you.
Just trying to help you get to the bottom of this. For all 60 owners actually. Might help on future spare parts grabs.
Is yours clocked to the pass. side like this one?

 

[elripster]

No worries. I am getting ready to go to the garage and grind. I don't think mine is clocked like that but will check.

 

[FJ60Cam]

What was the point of clocking it? To move the t-case up?

I have a *theory*. Clocking makes everything worse because it rotates the t-case lower. The t-case sits lower, the drive shaft is lower etc. This is another reason why an earlier bellhousing is more desirable, no downward rotation and better clearance under the t-case.

But I think it allowed Toyota to stop using the front double cardan front shaft which probably saved them $100 per unit. Tons of people in snowy places would in theory, engage their hubs at the start of winter and then drive like that all winter shifting into 4WD as needed from the warm cab. With the original set up with the original flange angles, the drive shaft would not vibrate due to the DC shaft. If you go to a standard driveshaft, you need to make the angle better and the way to do that is to rotate the output down and lower the output. That makes the angles align better and minimizes driveshaft vibration.

I would welcome other theories!

 

[FJ60Cam]

D'oh! I was looking at it backwards. It does move it down.

I'll buy the bean counter theory!

 

[elripster]

Mine is squarely aligned and has no double cardan. My trans is in though which is nice.

Congrats. For the win, what style of slave cylinder does it use? Is the tip adjustable? If so you have a 2F bellhousing labeled 3F which makes it a transitional variant. Very cool. First of these I've seen or heard of.

 

[OGBeno]

Cool on getting the trans in.

Andy's theory would make sense knowing how and why Toyota does things.

The transitional bell housings are rare actually.

 

[elripster]

Slave bolts bolts to the side with two fasteners. I don't know if the tip is adjustable. To be honest I have never had to adjust it. It self bleeds and seems to self adjust like most hydraulic slaves.

I will take a closer look tomorrow. Having a victory beer at the moment.

Hey Frank:

Was your H55F new or used (ie: from another application)?

If the latter that might have something to do with it as well since the H55 sits behind a lot of Land Cruiser applications as well as behind the Coaster bus and 1 ton trucks in different markets.


Enjoy the beer!

 

[elripster]

I bought my h55 new. I believe it was for the 4l diesel model.
