Axle Help

[K10A]

Hi all, I just purchased a pair of the axles for these trucks for a project of mine and am wondering where to find a TM or walk through with pictures of servicing them ?
I am going to be upgrading / converting my 1969 F600 to 4wd using this front axle and deuce transfer case and wheels / tires is my plan so far.
It is an ex railroad truck with a dump bed, big PTO winch in the front of the bed and a HIAB 174 Knuckle Boom crane.

Thanks for any help or suggestions!

Just making sure, “the early deuce” forum is for GMC G749 6x6 trucks, is that the running gear you have?

I’m pretty certain….

To clarify one thing I want to use an m35 transfer case.
Top loader Rockwell deuce axles would not work well due to the height.

Yes those are GMC axles and no you cannot use a M35 transfer case, the transfer needs to have reverse rotation on the front output.

I am going to flip the center diff to take care of that issue. Low pinion works better for this application.
A guy did it on his F600 dump truck , video on YouTube. Wesley Johnson.
Does flipping the chunk fix the issue?

Not my area of expertise. If, after flipping, both pinion flanges turn the same way to move the truck forward, you can use the M35 transfer.

Well I flipped the axle over it spins the same as the rear to move the axle forward.

Flip the center. Cut 1" off one axle and it works fine.

Awesome, thank you.

Now to find a suitable transfer case and associated parts, oh and a truck title. Haha

Do you wan a sprag or air shift?

 

[K10A]

I’m not sure. I don’t know how the sprague works. Probably air shift or a manual shift 223 like was originally in the 4x4 models.
can the air shift be converted to manual shift?

 

[K10A]

Anyone have the TM , breakdown or walkthrough?

 

[WillWagner]

There should be TMs in the Duece TM section that covers them. Unless you have OBA, your only option is sprag. I hated the one that was in my s-box. I converted to air shift and never looked back. If you had 120PSI regulated air supply, like a tank, the air shift would work.

 

[K10A]

I’ve looked through the TMs 3 times and am not sure which one to look at. I don’t see much for this series of truck. I must be missing it.

Man that’s a lot of pdf scrolling…

If I remember rightly, the G749 transfer is an underdrive box. No low range, either.
