VDJ79 H150 into HDJ80? (1 Viewer)

[Feistl]

Hey guys,

I was contemplating rebuilding my H151 in my 1991 HDJ80 until I saw the prices of bearings and 2nd gear synchros...

I’ve noticed there are some H150s from the VDJ79s floating around on eBay for less than the price of a set of bearings for my H151.

Apart from the first gear ratio differences, does anyone know if a vdj79 gearbox can be fitted into a 80 series? Either reusing the 80 series transfer case or swapping that over as well...

Cheers

Ps not sure if this should be in the diesel section or not.

I have often wondered the same, if it comes out of a HDJ79 I'm 99% certain it will fit, I often want a lower first gear with 35s.
I haven't been able to determine if the V8 has a different input shaft.
See if you can find a h152 out of a post my17 VDJ7# then you get a short first and a taller 5th.

Will need to use your input shaft, front bearing retainer and bell housing from the H151f and swap it into the VDJ H150f. Transfer case will bolt on.

Hey Locked,

What about if someone already has an H150, would I need to swap out input shafts? Do you know if it is plug and play otherwise? If not, how much needs to be swapped over or updated? I'd love to get an H152 if the bellhousing spacer and input extension just needs removed.

I appreciate any ipnut and apologize if I hijacked. I think that there are many on the forum who have been wondering the exact same thing. We need a taller 5th gear!

That all depends on what the H150f is out of and what its going back into. The H150f out of a 1hz 80 series has small input shaft, fine spline. The H150f out of a HDJ79 has the larger input, coarse 14 spline. The H150f out of a VDJ79 has the same coarse spline as the HDJ but is longer in length.

If your asking if the H152f can into say a HDJ79, yes it can but you will need the bellhousing, front bearing retainer and input shaft from said HDJ79 H150f box.

Hey Locked,

My H150 is out of an HZJ80 (I think) I have the 275mm clutch and related, fine spline. Not 100% sure what truck it is out of honestly but think it is as stated. I am looking more for whether the actual box is the same dimensionally and if the only thing necessary to change is the input shaft. I suppose it would be about a 2 minute discussion in person but will turn out to be a number of emails or posts. I thank you in advance for all info you're able to provide.

On a side note, do you know more about the Terrain Tamer 5th gear swap for these trannies? Know of anyone who has performed the 5th gear swap? Impressions? Worth it? Waste? I suppose that if I were to entertain the 5th gear I would also need to entertain an entire overhaul of the transmission due to having to take the entire thing apart, yea?

Again, thank you.

Hey locked79, thank you so much for your help so far.

So I’ve got a bit more info about the H150F gearbox I’m looking at... it’s from a 2013 VDJ76 series (which I think is the turbo V8).

If I swap the input shaft do you think it would bolt into my 91 1HDT?

Secondly, I’ve read that the V8 input shafts are like 5mm longer but can be cut with an angle grinder and with a custom spigot bearing be used with a 1HDT (so no need to swap the input shaft). Any truth to this?

Thanks again mate, really appreciate it.

I've just done this (last week) - well sort of anyway. As mentioned, your TC will bolt straight up. But if you get a TC in the deal it's no bad thing as it'l be that much newer and less worn.

The H150F from a 2013 VDJ79 will have the old 5th ratio (same as yours) - they changed to the H152F in 2016 and got the higher 5th and 2nd. You need your input shaft and bearing retainer as mentioned. The V8 shaft is way longer - much more than 5mm, forget using it. Only use is a nice clutch install tool for the turbo/1FZ clutches. You need to pull the box down quite a way to change shafts - basically pull the cover off and drop the counter shaft. All doable with basic workshop tools (a press helps for swapping the input bearing though) including a decent puller as the reverse hub is TIGHT.

I actually put mine into an HZJ79, but it had a new HZJ80 input shaft, bearing retainer and second hand HZJ80 bellhousing. For less than the price of a rerace of the rooted R151 (let alone repair) I had a low km, very recent massively upgraded box with transfer case. Win win win!

 

[Feistl]

Fantastic post, cheers

Out of interest what did the new input shaft cost you?

I’m kinda hoping to sell off my old H151 to cover some of the upgrade cost. It’s not much use without an input shaft lol.

Oh and are the VDJ full time or part time 4wd from factory?

No worries - thought it was rather timely! Input shaft was $330, genuine from Don Kyatt (who trade under Terrain Tamer it seems). The bearing retainer was $130. The input shaft was $450 from toyota (with a trade discount) and there were none in Japan. Don Kyatt had two on the shelf...
Yeah you could get something for the box for sure, but as you say it's less attractive with the input shaft. Also means you have to pull two down, but maybe do to the old one first for practice...
VDJ79s are all part time, certainly in Australia... Pretty sure it's the same case with a different linkage mechanism as the 80

Nice work Harry! Been waiting to see someone do this.
If the gearbox is new-ish, a new input shaft would be well worth considering too.

Thanks Dave - I'm pretty satisfied with how it went now. It's great because it means there's a large supply of cheap excellent and strong gearboxes available for any cruisers (if you want a 100 GXL one you just need to source a case), and there will be for many many years to come! The wrecker I got it off had about 5 to chose from and he said he'd never sold one as no one wants them because they never fail. I'm trying to work out how I can justify an H152f for my 105...

And yes it'd be sad to put a flogged out old input shaft into a pristine low km box!

 

[Workhorse]

So did you perform an HZJ H150 input shaft swap on an H152? Have you driven it yet? Impressions?

Thank you for the info and photos!

Sorry to disappoint - no mine was the H150f from a pre-update VDJ79, 2014 I think. I've driven it a bit - has that nice very firm posotive shift feel of any fresh H box. I'm actually think an H152f wouldn't be such a good match behind a 1HZ, it needs all the help it can get and I can see lower revs in 2nd and 5th making things worse. Behind any of the 1HD***s however - much more attractive, and cheaper than re gearing diffs for sure

If i understand correctly, the pre 2016 and post 2016 VDJ H15* will be the same ( other that 2nd and 5th), meaning the required input shaft and cover plate swapped and all should work? Thank you for the information.

I looked at doing exactly what @wedgetail has done, when I was researching, input shaft part numbers and synchro ring part numbers changed a few times over the years. A change in part number always raises a question on interchangeability.
There was changes to some synchro assemblies early on too.

It's good to hear that @wedgetail has done it with no issues.

 

[wedgetail]

Yes I can see the potential for interchangeability being an issue. The thing is I’d read at least a couple of accounts of people swapping shafts with vdjs so I can’t take credit for being the pioneer. I guess you can have two synchros that fit the one shaft. Also that’s the only bit that needs to interchange - the rest it doesn’t matter as it’ll all stay untouched. I guess if you were concerned about h152 interchangeability you could check they still use the same input shaft. Unfortunately my parts listing doesn’t go past 2014. Anyone for a PN for it?

Hi Wedgetail

Like you looking to put a H152f (0.75 5th gear) into a HZJ105R (After Market Turbo) - so doing lots of research.
Have you progressed on this proposal ?
I would be interested to work with you in this ?

1 main question for me is which GBox gearshift to use and any tunnel mods to fit it ? , clearance in the cabin ??.

For databases
I have managed to find both the pre and post 2017 H150/152 for the VDJ 7#R
Using whenever possible the AUS or in absence the GEN - country codes
Using the HDJ78R or VZJ78R = Troopy- LX -versions

For individual parts - Im not so sure that are the H152 - it just says from 08-2016 -->


Part # for the VJD7# gearbox H150f = 33030-60B91 / H142f= 33030-60C50 (but all references only show the H152 from 08 -2016 up to 01-2018 thereafter it disapears ??) - no Gbox apparently !! - what gives ?

Here are the part # ive deducted so far - and in Red the BOM
Note :- I intend to keep the fulltime box - and convert the input gear to the H box output shaft splines
I originally intended the H151 - but my RPM increases by annother 128 RPM @ 100k - due to the 4.3 diffs
With the H152 - I drop 263 RPM ~11%

@TurboDennis has put an H152 into his HDFT 80 series. I'm sure he'd chime in on this.
