AC HD10 STEERING CLUTCHES

gglogocopy.jpg (46227 bytes)

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.

CAUTION_2.jpg (9703 bytes)   The 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.

GOOD_TO_KNOW.jpg (7921 bytes)  SEARCHING FOR PARTS!?          When searching for parts, the part numbers are, of course, very important.  It is GOOD TO KNOW that the part numbers in your parts manuals are probably NOT the part numbers that you want to search for!!! If you have a manual showing 6 digit part numbers, and the early machines and their parts manuals mostly show 6 digit numbers, and you want to replace a bearing or seal for example, your local bearing and seal house will not be able to help you if you give them that 6 digit number!   For most of the early construction equipment and loaders you will want to add a  "70" in front of the 6 digit number to make an 8 digit number.  Depending on product line, you may have to add a "73" in front of the 6 digit number.  If you give your local bearing and seal house the 8 digit part number they will be able to help you!   (or if you are doing a Google search)  As with most rules, there are always exceptions but your odds of finding the part that you need greatly increase if you do follow this rule.       "Use an 8 digit part number by adding a "70" or "73" to your 6 digit number."
