fuel system basics -- converting FJ60 to diesel

I'm actually getting close to working on this again... Got my BJ42, and it's running pretty darned well. Once we get Pete's VW bus out of my workshop, it's the 60's turn to get back in there and get done. I really want to trim the fleet down to just two vehicles. Having two diesel Cruisers will just be icing on the cake. :D
 
Bump. Anyone out there successfully installed a OM617.952 into a 60 or 62?
Here's some stats to compare:

2H (Hino/Toyota):
3980 cc
102 hp
177 ft./lbs. torque
91mm bore
102mm stroke

MB OM617.952 (the 5-cylinder turbo diesel, 1981-1985 from 300D, 300CD and 300TD--MB's hands down most durable and reliable motor ever built), not to be confused with the earlier 617.951:
2998 cc
123-125 hp
170 ft./lbs. torque
90.9mm bore
92.4mm stroke

The FJ60's curb weight is rated at 4246 lbs.
The MB 300TD (the wagon) is 3780.
The 300GD (the gelandewagen, short wheel base) is 4280. That truck runs on this 5-cylinder motor, is reputed to be slow-ish, just like the HJ60.

As an owner of both a 300TD and an HJ60, I can say that the MB is peppier, by a fair amount. In a quarter mile, I'd bet the MB would be several car lengths ahead of me.

So, let the nay-sayers be forewarned, these motors perform very comparably. The 2H is bigger (displacement), but has fewer horses, but slightly more torque.

:confused:Why compare, turbo against non turbo and one that does not have a transfer case fitted? Also the gearing is hardly compatible being built for two different purposes.

seems pretty obvious to me, with the 2H being a standard in the 60 for so long it gives one a decent idea of what to expect in performance. actually tells me alot, looks like the MB with smaller displacement but similar power will return similar performance at much better mileage.
being in a country that imported diesel cruisers i'll assume you dont get the itch like us yanks to not only get diesel power but do it with decent local parts supply. might as well get over the counter parts if we are gonna go through all the hassle and expense of swapping to diesel. at least that was the motivation for my non-toyota engine swap.

Well it is not so obvious to me.I was not commenting on the MB Diesel at all just pointing out that comparing the 4WD with a sedan was an unrealistic comparison. Compare a turbo with a turbo even the 2H fitted with a turbo is streets ahead of the standard 2H and develops more HP than the 12HT. Also comparing a sedan to a 4 wheel drive with a transfer case. Far greater horsepower is lost in a gearbox with a transfer case than a sedan gearbox with no transfer. The gear ratios in the sedan gearbox are chosen for optimum performance where the 4wd ratios are selected as a trade off for hard country off road and on road work. Bit like comparing a stock horse to a plow horse. LOL. Apples and mangoes. :cheers:
 
i dont know why your bringing gear and transfer cases into it, one engine makes 102hp and the other makes 123hp, you put them in the same vehicle and what do ya get? your also missing the point that we dont have 2H engines here. i guess we'll just have to disagree.
 
I've driven a G-wagen that had been converted to diesel with the om617a. Seemed to drive great to me. It'll blow you away if you pump up the turbo and send your EGTs through the roof. Set at a normal setting, it is comparable to the 280GE. Never driven a HJ60 but the Toyota engineers seemed to think that was an o.k. setup.

(O.K. "blow you away" is a comparitive statement, no race cars, if you want a box race car go with a G500 or G55.)

:DI did not miss the point,,,,I responded to this part of statement above which was part of the post comparing the acceleration of the cruiser to a MB sedan.:idea: Pretty obvious to me.And I am aware:rolleyes: you never got the 2H,12Ht,1hz,1HDT, 1HDFT or 1HDFTE :crybaby:only the 2H in the forklift trucks. Time out.:beer::beer:
 
To answer the original question, no, my 60 is still parked in front of my shop. Engine is in, tranny is in, t-case is on the shelf.

My buddy's VW bus is in line ahead of the 60. Once that's done, we'll get back to the 60 and figure out how to make her live again.
 
FWIW there is a Land Rover guy, Jim Young who is playing with Mercedes conversions, He has a 4cyl non turbo in his 88" and is building a 109 with the 5cyl turbo engine, he is fabricating an adapter fot the NP435:

That adapter is in the development stage.

Here is his site:

Wow,

I just read through this entire thing. Great up until November Dec and then it just fell apart with arguments about will it be good enough or not.

I'm thinking lets revive this thread with info on someone who has done it. There HAS to be someone out of all this that actually finished something.

I'm all for using the stock transmission/transfer case and adapting it to the MB engine.

I'm assuming 4x4labs has not come up with anything. None of the links on his web page work and I e-mailed him but have yet to hear back (only been a day). I've had a few mercedes and am about to come into about a dozen of them with plenty of good engines. So with all of those some euros and 4 speeds I've got plenty of stuff and parts to make this happen. All I really need that I have yet to hear or see is the adapter.

I would hate to dish out the dough for it to be designed and made if one is already out there.

I was going the 6.2L to SM465/NP205 and centered rear diff just becuase that is what I have sitting in my garage. But if I could put a Mercedes in it I would be much happier. I know the engine very well, it is extremely reliable, and easy to work on. Not to mention CHEAP to FREE.

Hopefully someone can chime in but if there is nothing out there I might have to put my 4bt project (1956 F-100) to the side burner and just get this done. I'm sure my local Machine shop could get me something going. I'm new to the whole adapter game so I may be asking for help.

Git-er-Done and please tell me someone already has it figured out. 2 years of talk and no show is disappointing.
 
I emailed 4x4 labs last week about the mb conversion and got an email response.
They said they just got an adapter plate and were working on it.
That I would hear back from them in a month.
That is all the detail they provided....
 
That is good you got a response. I'm sure I will get one in awhile. Well if they have an adaptor plate that is one step (biggest one I think) In the right direction. I would hate to hold my breath and can always work on my other project but before I put money into this gas engine anymore I wouldn't mind doing the swap first.

Read thru the Toyota runner swap. He used the Automatic so that is cheating. I still want a 4x4 machine just with a familiar diesel I can trust on the trail. Still trying to figure this whole 2 bellhousing thing. Guessing it is the Mercedes Bellhousing mated to the Toyota Bellhousing but with the right distance between in order for input shafts to mate correctly. Also of course using both flex/flywheel plates. It makes sense and shounds eay but how easy is it really?
 
I just received an email from Luke@4x4labs today, but it was not in regards to the diesel conversion kit. I'm sure he is swamped with all the interest in this conversion.
