20 ton Crane axles

[Redneck lowrider]

just picked up a full set of 20 ton Rockwell axles 2 rear, 1 front, and transfer case, all in excellent shape...was wondering what the may be worth and more importantly, where can I find parts ???

 

[porkysplace]

welcome

Sorry about that !

Looks to me like they are different ratios. Good luck with that. Do you know what the crane model# was?

 

[wreckerman893]

Are you talking about this crane?

If so I can't think of a use for them....geared very low.....the cranes were powered by hydrolic motors from a huge pump driven by a 903 Cummins V-8.

My unit at Fort Benning had them......they got every little use because it was so hard to move them around post.

Thay are not different ratios, all axles are the same, one is a pic of the t-case tag

 

[wreckerman893]

Never mind.

 

[Redneck lowrider]

Wreckerman, It looked similar but was a 6x6

Thats good, it would suck to have a different ratio problem. Still, those ratios are not very good imho. What size tires are on there?

Chris, the T226 is the transfer case and a transfer case ration of 2.48 isn't that bad...

Opps missed the tag for the front steer axle...

Those axles belonged to the Quickway Model M-200 Crane Shovel
TM 5-3810-207-35

yeah that is very tall gear.. like 45 MPH all wound out in OD (deuce or 5 ton OD trans) at 2600 RPM lol even with a 53" tire.


Hey Locada57 Has one of them and it runs!

I can plainly see the 2.48, what does the other one say, so I am not mistaken.

I edited my post, I missed the second image of the front steering axle tag. I also posted the TM and an image of an actual M-200 crane.

Sorry

Excellent detective work on this Bighurt. I was stumped as to application, my 1970's 20 ton P&H M320T has the same drivetrain but the transfer case does not have that emergency brake drum.

 

[gimpyrobb]

Well, for an off road rig, I think that is much better(I thought it said1.0/1.7 like a dual speed axle). Good luck if you plan on using it on pavement.

I just looked up the part number found a NSN, and then found a technical manual that used it...once I had the TM I verified that the whole trail of breadcrumbs in fact lead to something real.

The hard part was finding an NSN against a prt# that is obsolete.

Sometimes I have my days...

Wasn't someone on the board looking for an extra deep gear set a while back? I can't remember who that was.

I would see if the AIR BRAKES set up would bolt up to 5t axles, if so then pull ALL the BRAKE parts and sell them as a air brake axle converson kit, the valves could be had from any big truck parts house

 

[Redneck lowrider]

Bighurt, where did you locate the tech manual, and Most important, are there any parts such as seals, bearings, bushings and anything else for that matter available for these monsters ?

 

[73m819]

any good bearing house should get be able to get you bearing, seals. ect
