H55 to split case question (1 Viewer)

[UZJ40]

Posted this in the 40 section with no luck yet...

When I picked up my H55, the seller pointed out a little plastic 'cup' on his split case that drips oil on the 5th gear assy on the H55. I got home and didn't see the cup or setting for it on my split case (out of an 84 60). Do I need a different case? Is there any different way to oil the 5th gear without this? Thanks

When I did my H55F for my 83 FJ60 - I needed to get a newer style case in order for it to be completely compatible (used one from a 62) - and yes you need the oiler. Maybe someone else can chime in on your year and the particulars

 

[orangefj45]

The red arrow in your pic points to a bolt hole only utilized on the "short" h42 transmission but not the location of the 5th gear oiler. The recess for the oiler is about 4 inches below that hole.
I'm not sure what year case needs to be used, but I think it's mid 85 and newer. The early cases are not cast/machined for the oiler.

I have a 1983 split case with a build date of 11/82 that is compatible with the H55. You might find this write up helpful. There is a good pic of the oiler provision as well.

The Wagon Way

Overseas H55's appeared as early as 83 so toyota was using tcases that fit all the trannys. The cases that definately cannot be used on any long case 4 speed or the H55 are the 80-82, machine work is not compatible

But you should be able to use that 84 splitcase as it should have the oiler provision. If it is currently on a shortcase four speed there is a spacer that you won't use on the H55

Hey Georg, isn't that bolt hole next to the arrow from tcases mounted to some long case four speeds? I always thought it went into the web of the spacer, something that isn't on the H55... Nor is it on the short H42 laying on my shop floor, sorry

you're correct tony. the early cases do not have the bolt hole or a provision for it. the mid cases have the boss but it's not drilled. the late cases ( behind the long h42 ) have the bolt hole. needs to be plugged when bolting to an h55f.

The boss is even on the 62 case I put behind my diesel, god knows why...

[orangefj45]

probably cheaper just to leave it in the casting then change it.........

To answer the OPs question: You need the oiler provision or you might burn out the 5th gear on your new H55f.

You will need to have this provision for the plastic oiler cup to fit in:

Pic of early t'case is from this THREAD which should have been FAQ'd but wasn't.

Later one looks like this, with plastic oiler cup.

 

[Kynot62]

It would be interesting to see just how much that oiler cup actually does. Considering all it does is redirect some of the splash into the end of the counter shaft. Realistically 99% of 5th gear oiling is still done by the gears running in the pool of oil in the gear box.

I have heard of a few guys running without it for years with no ill effects but I didn't chance it on mine.

But I still would not recommend running without it.

I have the oil funnel in stock, iirc they're about $7.

I have seen an h55f that was run without the funnel. The countershaft was bad right at the 5th counter gear bearing surface. Theres always oil on the bearing but without the oiler there's no oil flow. So if a piece of debris gets into the bearing then it can and will cause damage. The oiler keeps the oil flowing thru the bearing thus washing things "along". I would not run an h55f without the oiler. Ever.

Thanks guys... I'm on the hunt for a later style case.

Just did mine

I just put a new H55f in my 84' model. My case had the oiler cup hole, the machined recess for the bearing and only required the plug in the bolt hole. I also picked up a late model transfer case shifter from OrangeFJ45 and swapped it out. I had read numerous threads and most indicated the 84's are a unique year which has both the bearing surface machined and the oiler cup provision.

The 5 speed is great and well worth it. Changes the whole 60 driving experience!

If your donor case does not have the oiler cup provision, it isn't from an 84. Only the 81-82 and possibly very early 83 did not have the casting for the oiler cup.


Are you certain that your donor case is from an 84? If it did, I'll bet the case had been swapped for a repair sometime in the past.

83 and 84 are not so much unique as oddball. They have the later spacer style machine work but are bolted to early non spacer trannies. The fact that you had to plug the bolt hole indicates that it was an 85 or later.

Did you have a spacer style tranny in your 84? Tranny and tcase could have both been changed out at one time

I was TOLD it was from an 84... Oh well, I can only blame myself for not researching it properly before I bought it. I actually didn't know I needed that specific splitcase till the next day when the seller of the h55 showed me what to look for.

[deltapine1]

No spacer hence I had to score a late case shifter from OrangeFJ45. I am the second owner and have the history on it from the PO. I certain it was the original tranny and transfer case. Odd is right!

 

[mtn2roady]

For archival purposes, adding the pic of the hole that needs to be plugged when mating an h55F to a previously mated transfer case with the 4 speed. Note it's just directly above oiler location. Got this straight fro. George @valley hybrids along with the rebuild kit...thanks George!

 

[orangefj45]

You bet!

Thanks for sending business my way, I appreciate it.
Let me know if you need any more help with the task at hand!
