Maybe I miss something in my reading .. you have a complete H55F tranny and t'case but don't the right bellhousing to match with the 1HZ ...
Bu post ago you show a H150 tranny .. you don't want to use the H150 .?
You have a 1HZ, 21 spline output. You need a bellhousing (10 bolt) to fit a H55f transmission?
What are some of the particular models that this would be coming out of?
Thanks,




This what I am taking over to the dealership tomorrow. I know that they are going to scare the pants off me with some crazy price but it will be good to know just the same. Guys thanks so much. If you guys can locate it, the Clutch Housing p/n 31111-60230.; Per the parts guide it was on HZJ70, 73, 75, and 77. For the parts guide I used an HZJ 77 from 2000 in order to pull up the diagram.


How'd it go John?
I was surprised that Halls even had a websitethey are more of a big shed out in the burbs, with parts sold out the front, and a stream of containers heading out the back full of 40's and bits and pieces for the US- rather than a slick online business. It seems the website is still in construction.
I dropped by my friends house, planning to take a template of the front of his H55, but he has sent it off for a rebuild so that he can install it. Doh!
It was his opinion that the HZJ75 bellhousing we are talking of should be what you need... that the H55 was pretty much standard for them...
nonetheless, we really need to find some way to figure it out.
Any ideas anyone? Anyone know any Aussie diesel gurus who would be worth contacting and asking?
I am more than happy to do the legwork going out and grabbing it and sending it off, but I am not sure how to make certain it is the right part- and I would hate to be responsible for wasting John's time and money if it is not the right part.
I'll give Halls a call again tomorrow from work and hope that there is someone more knowledgeable available- also will grab a price.
(... maybe if they have a h55 in stock- possibly unlikely as they are pretty hot property now- then they might be convinced to line one up to one of the HZJ75 bellhousings and see if it is right... either way I will try to get a bit more from them on the phone)
Hans.

Hi John/Hans
I stress that I know very little about these conversions.
But I suspect you may/could need a specific input shaft in the H55 transmission to match the 1HZ (as well as having the right bellhousing).
Does this post support this suspicion?:
https://forum.ih8mud.com/diesel-jdm-parts/153081-1hz-h55f-bellhousing.html
Edit: And that could explain the larger number of vehicle models using the "H55 casing" compared to those using the "1HZ-compatible H55 transmission as a whole" in #311 (assuming those numbers do represent the H55 transmission - which I'm not sure of at this stage).
Cheers
Tom
there is no big deal really since the old H55F are 19 splines input shaft IIRC and newwers with 1HZ are 21 splines at the input shart ..
But both discs share the same 275mm diameter ..
