I have a 1986 Yale GDP060 (LCNSBV086)
This machine is in great overall condition except the rare straight 6 Mazda ZB Diesel engine is shot.
It spun a rod bearing and the PO (prev owner) kept running it....so now the crank is worn.025 under size. Parts for this engine are ASStronomically expensive from yale.
And so my $150 investment has been setting for about 5 years....
This summer I picked up a 1970 Yale G83P and have gone thru it, "undoing all the wrong doing that's been done" (I'd like to write a country song with that line in it some day) and the ole slant six in it purrs like a kitten now.
Well, the gears started turning, and I got the idea to replace the mazda diesel in the '86 with a slant 6.
A transmission adapter will have to be machined/fabed to couple the engine/ trans.
The good news is, the hyd pumps run off the trans, so no extra pump mounts will have to be made.
And, I already drug home a super rusty 89 dodge pickup that has a 1980 slant 6 in it....which runs pretty good....probably better with a tune up, but no smoke or lifter noise. $200 for the truck...
Oh, and I checked.....the slant 6 looks like it turns the same direction as the Mazda.....don't need THAT surprise!
Would this F/L have ever of had a slant 6 engine in it?
Any chance of finding an adapter plate already made that would hook the chrysler to the SAE bellhousing on the F/L automatic trans?
This is more of a hobby project for me than an all out requirement to get the machine functional.
I need forklifts for my business (machine shop) a half hour or so a week, not 8 hours a day.
Your thoughts?

The transmission is the same for GP LC to the GDP LC. I believe the GLP LC had the slant six in it from the factory. The torque converter and plates are different. Good Luck.
"I had to put 2 pistons, bearings , and gaskets in a TM Mazda a couple years ago. The pistons were $400 each without rings, oil pan gasket $100, head gasket $100, etc."
Thank you for confirming the parts price insanity mrfixit!
They will scare the heck outta you at Yale parts Dept.
I think Piston rings were like $25....EACH.
Forget that BS....
On the gearing, I think it's close to the same believe it or not. I -think- both motors in the F/L application are used at 2200 max RPM....I'd like to confirm that on the diesel tho...
The good news is the /6 makes peak torque at 1600RPM.
Flywheel/TC adapter will be the biggest challenge of the project. I am hoping to use the Cast plate that was between the trans and the diesel on the /6 with some machining and modifications. If not, then a new plate altogether....
Even a 3K G83P had the slant 6. I think they called it a ramp climber, and it could certainly climb a ramp, even at 1/4 throttle.

Keep in mind a slant 6 operates at a much higher RPM than a diesel and I would think a diesel forklift is geared for a slower turning motor. You will also have to figure out how to connect the flywheel to the torque converter.
"In that era Yale used the slant 6 starting in the class four models. (11k capacity through 15 k capacity.)"
Wow, a slant 6 in those big trucks??
I have a 1970 G83 (only 4K) that has a slant 6 in it.
Thanks for the link, but I have given up on the Diesel for cost reasons.
It will still be probably $2000 or more to rebuild it.
Just not worth it for my application.
If I could find a reasonably priced ($500-1000??) used diesel, I would consider that option.

Try E.P.S. (engine power source) for a crank and a reman kit for the diesel engine. That lift would have never used a slant 6. In that era Yale used the slant 6 starting in the class four models. (11k capacity through 15 k capacity.)
