The 977 Traxcavators actually began with the production
of the #6 10A Traxcavator, built on the D6 9U crawler frame. The dry type steering
clutch packs were retained through the 20A model and the 53A's serial number 53A 1 thru
1906. Beginning with the 53A series the inner driving drums and quantity of discs
decreased to ten bimetallic and 10 steel discs, using the D7 sized 7M5001 inner driving
drum instead of the D6 sized 7M5002. Brake bands remained the same as did their
Twelve (12) bimetallic friction discs and twelve (12) steel separator plates are required
for each clutch pack. (Ten each for the 977 53A dry clutches) Unless severe damage has
occurred, you often have to replace only the bimetallic friction discs. This keeps your
costs down quite a bit. I would highly recommend that you check your brake bands at this
time, unless you just enjoy pulling wrenches. All parts listed below are new replacement
parts, non oem.
Brake Band relining kit $42.00 per clutch (a band is 3 sections, the price includes all
rivets and linings for one complete brake band)

These bands will fit the D7 dry type steering clutches for the models D7 7M, D7 3T, 4T,
6T, and D7 17A.
The part numbers for these bands went through quite an evolution as did the bands.
The early bands, for the model 7M's and early 3T's did not have any reinforcing plates at
the joints. When the part numbers went from the "B" part numbers to the
"F" part numbers, reinforcing plates were added to the "6F" and on all
bands thereafter. Upper Band P/N's 6B7484->6F6285->1M0547->8E7624
Center Band P/N's 6B7352->6F2686->8E7622 Lower Band P/N's
