planning an LDS swap

[gringeltaube]

If it's not too much trouble, I'd really appreciate it. Knowing the diameter of the input shaft where is rides on the pilot bearing would also be really helpful.

Yes, it's 1.5" x 10 splines, 0.230" width.
Pilot diameter is 0.747".

...and did you get those towbar legs yet?

Got them, thank you.

 

[jesusgatos]

No, have to pull the old engine/trans out first and then am going to tow it down to have the bare rolling chassis sandblasted and painted (not going to remove the M109 box). THEN I'll bring it back and install the new engine. Just found a guy that's got a big Unimog and he agreed to help me tow it down there and back. Now I've just gotta coordinate schedules with the sandblaster/painter.

A Mog? I hope its the "HULK" of Mogs.

 

[jesusgatos]

Yeah, it's a U500...

How is this coming along? opcorn:

 

[jesusgatos]

Trying to coordinate a tow down to get the rig sandblasted and painted, then it will finally be time to reassemble. Has been virtually no progress in recent months, as can't really do anything until it's painted, and my sandblaster/painter has been jammed-up with other projects.

 

[jesusgatos]

Finally got the chassis back. It's been sandblasted and painted, and I've installed the new transfercase (thanks again clinto!). Never got around to ordering gaskets and that stuff, so am going to order now and will install the new engine as soon as I have everything I need.

 

[jesusgatos]

I haven't had to order too many military-specific parts, so... who should I contact about purchasing gaskets and stuff? Am in CA right now, if there's anybody on the west coast, not that it really matters much I guess.

EDIT: Just talked to someone at Memphis Equipment and they were able to get me everything I need. Gentleman was real nice, and patient! Was asking a lot of dumb questions, about parts I'm not familiar with, and he answered them all with a great attitude. Appreciate that kind of service.

Looking forward to hearing how a 109 does with an LDS. I'm rebuilding an LDS to put in my 109.

The engine-swap is now officially in-progress.

 

[jesusgatos]

Going to pull the transmission and bellhousing off of the old engine right now. Got a new clutch for the swap, but am wondering if I can use any of the new 5-ton parts (flywheel, pressure-plate, etc.). Nevermind. Was obvious as soon as I pulled the transmission off the old engine.

The clutch fibers on the brand new clutch are about .415" thick, and the old clutch is .400" thick. Flywheel is being resurfaced right now, and the pressure-plate is in pretty good shape. Should I bother installing the new clutch when it seems like there's plenty of life left in the old one?

 

[jesusgatos]

Oh, and which manual should I refer to for details about how to R&R the transmission and bellhousing and all this stuff? -20? -34? Which version?

 

[gimpyrobb]

New motor with an old 25a generator on it huh? Make sure you swap THAT out.

Dunno anything about the generators on these things, but am planning on replacing it with a dual alternator setup.

 

[Heath_h49008]

Will a dual output Hummer alt make enough amps for you? Might be easier.

 

[jesusgatos]

They're pretty expensive and I'd prefer to use parts that I could replace at any auto parts store.

 

[jesusgatos]

Found the torque specs for the flywheel, but what about the bellhousing and transmission? Probably not too critical, but would like to do this 'right'.

 

[Clay James]

I just checked and it didn't show it for those. On page 1-6 of TM9-2815-210-34-2-1.pdf it has a table of torque values.

 

[jesusgatos]

What are these parts and which version do I want to use?
