D2 Steering Clutches
D2 / 933 (11A, 42A) STEERING CLUTCHES

  For the Cat crawlers D2 3J-5J 4U-5U vintage crawlers and dozers, and the 933 11A and later 42A models of the crawler loaders, we can supply some of the drums, inner and outer, pressure plates and parts as needed. The discs, both the driving discs and the steel discs we can supply new.  Be sure and check your springs too.  If they are bent, or if any are shorter than the others, replace as needed.  We sell the new outer springs at 7.00 ea and the inner springs at 5.00 ea

We highly recommend converting to the bimetallic driving discs vs. the old riveted on lining style discs. This is an update to the earlier style clutches and cuts down on the possibility of frozen clutches and gives increased life and higher coefficient of friction to your clutches for a longer period of time.

It requires 12 bimetallic discs and 12 steel discs per clutch (the old style used 8 ea).  Instead of using the 8 friction discs with the riveted on linings and 8 steel separator discs, you will use 12 bimetallic (sintered bronze) discs and 12 steel discs for each clutch.

The cost per clutch of course depends on how many steel discs you can use from your old clutch. If you can reuse your old steel discs, you only need 4 additional steel discs per clutch. The 12 bimetallic discs cost $252.00 per clutch (12 x $21) and the steel discs are $12.00 each. If you have to replace every single disc in each clutch the cost is 396.00 per clutch. If you can salvage your steel discs, you can save the cost of 8 steel discs, or $96.00 savings per clutch, bringing your cost per clutch to $300.00.
