AC HD10 STEERING CLUTCHES
|The Allis Chalmers HD10 crawler used, at
different times, different friction discs. The fiber discs, (70044478) when new measured
3/16" thick. If the fiber discs are worn down to approx 5/32" or have damaged
teeth, they should be replaced. The bimetallic discs used originally were replaced
temporarily by the fiber discs above, and then again replaced by a later style bimetallic
disc (which were thinner than the bimetallic discs originally used.)
So what do you measure and how many do you use!?
If your discs pass muster, as above, you can use as many as you like until your stack height reaches a height of 4 3/16" (plus or minus 1/16") Begin stacking your discs, WITH A FRICTION DISC FIRST (bimetallic or fiber) and alternate with the steel discs until your stack height reached the correct specification.
Whatever your clutches are equipped with, or whatever you want to equip them with, we have new ones on hand. We have had them made especially to fit your needs when repairing your HD10 steering clutches.
If you are using bimetallic discs, and alternating with steel discs, your clutch will be less prone to seize up, give you longer clutch life, and a higher overall coefficient of friction. You will eliminate the possibility of broken teeth on your fiber discs. Due to design, the HD10 steering clutch service is more difficult and labor intensive to work on than the simpler HD5, HD6 steering clutch process.
Upgrading to the bimetallic disc pack does cost more and
you are the only one that can make the decision between the two different styles of clutch
packs. For some people the labor and inconvenience involved in future steering
clutch repair is not a consideration, while for others it is very important. For the
difference in cost, you will end up with a superior clutch, much fewer headaches,
and less labor in the future if you convert to the BiMetallic discs.

following manuals are only guidelines. Watch your serial numbers closely and when
you think you have the correct information, CHECK AGAIN!!! Allis Chalmers made some confusing model
designations. In the beginning AC made an HD6 and the standard model, standard
gauge, was called HD6B. Do not confuse this HD6B with the later model HD6B!
They are entirely different machines in almost all circumstances.
You do not know what may have been done to your machine in previous repairs over the decades. Even the manuals are not always accurate so verify with casting numbers and compare them to part numbers that you find.
