Hello list.
I was under the truck last night and this is what I found:
(other than that February is ..... cold :-) )
Front and rear axles made by ROCKWELL-STANDARD CORPORATION
Ratio 6.72
ROCKWELL-STANDARD Model:
- Front axle: FC240 HX21
- Rear axles: C240 FHX20
The actuating air-cylinder and the electrical control switch is mounted in the rear of the axle housing.
These are covered by a curved plate on both rear axles as shown:

The front axle does not have this cover.
The electrical switch is a single throw, momentary action switch that controls the lights
(one for both rear-, and one for the front axle) mounted on the lock-up panel inside the cab.
The bad news is that the axle-housing itself is different.
It has a box-like extention welded on to the rear, left-hand side.
This extention has tapped holes for mounting the air-cylinder and control switch.
There are complete axles (used) for sale over here -
and complete vehicles......
- M621 with or without winch and M624 Dump truck.
(No M622 tankers or M623 vans)
....And how much for a 40 feet container across the Atlantic ??
