D4 STEERING CLUTCHES

The old D4 steering clutches, from the 4G/6G series, the 7J, 2T, 5T, and 6U/7U series originally used the riveted on lining style of friction discs. We can convert you to the bimetallic style friction discs and eliminate a lot of your steering clutch problems. 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.

Instead of using 8 friction discs with the riveted on linings and 8 steel separator discs, you will use 12 3F5504 bimetallic discs (sintered bronze) and 12 steel discs for each steering clutch. No other changes are required in inner driving drums or brake drums. You can, in most cases, re-use your existing 8 steel discs and merely add four more new steel discs to go with the 12 sintered bronze bimetallic discs needed for the conversion.

D4 3F5504 ( qty 12) Bimetallic friction discs @ $18.00 ea
D4 2B8955 (qty 12) Steel Discs $12.50 ea
