All kinds of fun thoughts on H55 gear oil from the diesel section: H55F tranny - gear or transmission fluid?? - https://forum.ih8mud.com/threads/h55f-tranny-gear-or-transmission-fluid.232524/

I've found the H55 to be a little hard shifting over some others. The full syn. GL-$ seems to help.

Thanks!
I was asking Georg about what fluids he recommends, he said any GL4, but he felt the full syns were a little noisier.
I guess I'll find out soon!

Can’t comment on noise but 25 years ago when I was road racing the Nissan transmissions seemed to shift best with a GM synthetic gear oil (or additive)? that was new at the time, unfortunately I can not recall the name…it likely doesn’t matter after all this time.

Noise in a pig, no way.

So unacceptable.

Are you talking the GM Synchromesh?

I think that can be used in place for a gearbox that calls for 30/40W...

A story from the Today I Learned (TIL) desk...

When I was pulling the bellhousing, I removed the starter from my little place where the transmission used to live. So I was reaching the fasteners from the rear of the Pig. The top one felt odd. When I got the starter off I set it aside and put it's fasteners with it. That is when I saw this:

As Amy Winehouse says, "What kind of ****ery is this?!?"
I thought someone cobbled this fastener together and then I moved on.

Fast forward to last night when @RUSH55 was sending me pics of a bellhousing he is helping me out with. I looked at the fasteners for the starter and then I had that "Ah-ha" moment. Toyota provides a stud up top in the bellhousing so you can hang the starter in position, and then get the lower fastener (bolt) secured. That is nice for those of us that don't have 3 arms.

It is always funny when your ass-umptions get blown up.

Catching up - the nut on the stud in my original bellhousing is 17mm. The one on the bellhousing @RUSH55 sent me was 19mm.

I always thought having the engine/drivetrain mounts on the bellhousing was pretty slick. You can pull the trans and t-case out without having to jack up and crib the engine.
Those bellhousings are extremely stout, somewhere around 60-70 lbs.

Thanks again @RUSH55 !!!

You really saved the day.

A bellhousing with un-molested threads from a 1979 Pig:

It came in a sweet crate:

 

[PabloCruise]

The mounts are very similar from '74 to '79.

It looks like they added provisions for a mount on the driver side mount at some point after '74:

Then it was time to add reliefs for H55F:

The powder coat guys had time to make it look pretty:

After the new pilot bearing was in, it was time for bellhousing, flywheel and clutch kit:

 

[PabloCruise]

I used Ultra Grey on the flywheel bolts to keep the oil where it belongs:

 

[PabloCruise]

I snugged the flywheel on, and then sealed each bolt, and then torqued.

Going in alternating pattern, I thought it might be good to mark which bolts were complete.

1 hash for RTV, 2 hashes for torqued:

 

[PabloCruise]

Make sure you put the disc in correctly:

 

[PabloCruise]

New bolts for the pressure plate. I made sure to clean the pressure plate and the flywheel surfaces:

 

[PabloCruise]

Now comes the fork and clips.

I had already put the pivot in the bellhousing before I installed:

 

[PabloCruise]

At this point it was time to do some stabbing!

It sure is nice to have friends with a forklift.

And a transmission jack. I feel like this was 20 minutes (probably less) of, "I think it needs to tilt more this way."

Ultimately, we got the job done!
