2h diesel (1 Viewer)

[Roastchestnuts]

I am curious on the 2h diesel engine and what transmissions, bellhousings, motor mounts work?

I am curious if the 2h diesel bolts up to the same location as the 2f engines? Does it require a different input shaft in the transmission? bell housing? I would assume it does. I am doing some research on different diesel engines that will swap in. RIght now its purley out of curiosity but maybe I will actually do it in the future.

Are 2h engines sleeved or not? from what I read some are some not? I would assume for rebuilding purposes you would want a sleved engine?

I am am thinking I want to do some sort of diesel swap in the future on my fj40 but I am not lookin to do lots and lots of fab work. at most welding in some motor mounts. Was also looking maybe to find a 1hz or a 2h. 1hz seems to be more work in a fj40 but would be a better option. flip side is I dont really want to turbo I just want a good reliable tractor (not that my 2f is not reliable)

again at this moment in time this is purely research to help me answer my own questions on what I want to do.

I am also a visual person and would love to see pictures of the 2h and 1hz in a FJ40. Please share if you have a diesel fj40.

I think a turbo belongs on a diesel more than than a gas engine because they are more heavy duty to handle the extra pressure, but that's just me. I'm not fond of the smell and taste of diesel, but I did like my multi-fueler deuce and half.

Be following along to learn what the diesel people say to answer your questions.

I just dont need to go fast and the turbos seem like an added expense for my use. as long as I can get to 55mph i would be happy. I am very cuirous about all that stuff. I guess I am asking because I want to know how much work the project will actually be and how hard to source some parts will be like a bell housing or flywheel (forgot to list that one above).

Another thing I toyed with the idea of is a H55 transmission too. I did notice that on Cruiserteq it list the h55 either configured inputshaft for the 2f, 2h, h, 12ht or for the 1hz. This made me curious about the fitmit in a fj40 actually and led to my post.

It'll be a lot of work and a lot of money. If you want to go diesel and don't care about it being turbo'd, I'd say go 1HZ. Parts availability is great, though still not necessarily cheap. Take any part from either a 2H or 1HZ, and google it. You'll find a whole lot more 1HZ parts. You can source a cross member, motor mounts, transmission shafts, bell housing etc all new for the 1HZ, plus rebuild kits are out there for very reasonable prices. Plus, I think NA, the 1HZ has about 30 more hp and 50+ lb/ft more than a 2H. Check cruiserteq and McKinnon's cruisers out of Australia for swap parts. I also think Poser on here sells a 1HZ swap kit.

I have a 12HT sitting in my shop im slowly getting ready to swap into my 40. It kind of fell in my lap, so I bought it. This wasn't my first diesel swap, so I knew that I was opening up my wallet well beyond what I paid for just the motor. However, I didn't realize how hard/pricey parts were for it until I started collecting them. The small things can really nickel and dime you, so try and buy as complete a setup as possible. If I had to do it over again, I'd probably have waited for a 1HDT variant and bought a complete unit with all accessories. The 1HZ was a consideration, but I'm at 6,500 ft, so the turbo was a non-negotiable for me.

HJ47 mounts will work, you'll need the actual rubber mounts, and the mount "arms" that bolt to the engine. You'll need an HJ47 bell housing (or an early HJ60 one same/same). You'll need an HJ47 transmission cross member and brackets too.. Both tailshaft lengths will change (Front is a longer shaft , rear is shorter). You'll need an H55F or an H41 with a coarse input spline. If you wanted to go to auto (lol) the A440F is a transmission option for the 2H.

The welded mounts on your chassis will already be in the correct location for a 2H

The 2H is a superb engine when in its element (remote desert tracks, dunes, tough environments).. on big hills it sucks but you learn to live with it for the other benefits it brings - supreme reliability when maintained, easy diagnosis, a long service life, and a tolerance for sub-optimal diesel quality. There are no parts for the 2H that are difficult to find if you're prepared to buy from Australia.

A turbo will help a 2H up the hills, but I'm really not a fan of turbos on indirect injected diesel engines. You might have a good outcome, but you're one dodgy injector away from grenading your engine and some people are just forever chasing heat issues after adding a turbo.

Sure, parts are more readily available for the 1HZ (the engine itself is even available brand new) but its got a rubber timing belt (), and a Bosch style VE rotary pump - consequently its a much quieter engine but its really got nothing else going for it., and the mounts in your chassis will be in the wrong place for the 1HZ. Its really a very unpleasant thought having a 1HZ in a 40.

Scroll down to "HJ47/HJ60 Engine/Power Steering Mounts" at my Toyota Diesel site - I have photos of the mounts you'll need, there's also images of the bellhousing you'll need.

One of my 2Hs in its element, the end of the Canning Stock Route in Australia.. 2000klms on goat tracks, over 900 sand dunes, 12 days of driving and one fuel stop.

Got, for my future FJ45 PUP resto, a good 2H unit (with all ancillaries) from a German Buschtaxi site member, for a fair price.
Followed ALL the above mentioned steps Duncan suggested! His site is an invaluable tool, thank you mate!
Lucky enough, been able to find (to chase is more realistic) the parts in Europe, so avoided pricey imports from Downunder. It hasn't been an easy task though...
Think I have everything on hand now, in order to go ahead with this swap.

PS. Will remain with the stock H41 4spd box and 3.70 axles, both are in excellent shape. No turbo thoughts....
Yes, more help at the diesel section and a useful thread here:

mounting question for 12ht/2h into a 40.

This is a bit of a confusing question so i'll do my best to elaborate. working on a 75 fj40 with a 2f. Im putting in a h55f/split case and have a late 40 series transmission cross member and some early 60 series brackets that will attach it to the frame. This current set up does not clock the...

I'd do a Mercedes OM606 if I were to do a diesel swap again

Nothing against the Mercedes diesels but I swapped to a 2f from a poorly installed SBC so could could see toyota when I open the hood. However I think If I were to go Non toyota or maybe even if I had to do it all over I would just do a SBC swap and do a sniper on it use the advance adapter that keeps trans and transfercase in the stock loction. Honestly If I ever find a fj40 or fj60 without the drivetrain this is what I might do. It would make such a fun driving land cruiser.

Agree the 2H will be an easier swap.

If you find one that’s in good shape, I’d just run it and skip the turbo for the above mentions of IDI.

Stupid simple engines and as stated most parts are still available from other countries or local vendors here.

I’d choose a 1hz if you happened to get a really good deal just because the swap is a bit more involved.

It makes sense, especially in the US.

I like diesels for the amount of power they can safely produce before turning into a grenade, range, and simplicity. A mechanically injected diesel is a zombie cockroach that just can't be killed other than through poor choices.

Nothing wrong with the Toyota diesels. Just there's a LOT that can be made to happen with the 606 pretty easily

The first diesel I had did not have a turbo and it was fine once you got up to speed but did not hold well on the hills if someone was in your way and you had to slow down. It did not recover well with out going deep into the transmission. I had to look farther down the road when pulling out to make sure I had room to accelerate into traffic. I have had turbo charged diesels after that truck and it really makes a difference.

I logged many hours behind a normally-aspirated 2H diesel and they are great engines. But the noise, smoke, and parts availability got old once the coolness factor wore off. Just one perspective.

I just finished a 2H into my HJ45. So far I like it a lot. It’s the same transmission as the 2F but different bellhousing. @duncanrm is the man! And helped me a lot on my build. A lot of my parts cruiser outfitters helped source. It was a lot of work but so far worth it. @tucker74 i think had a Mercedes in his pig he didn’t like too much.
