I don't have an exploded view,j ust some comments, as I have done this on my '51 SC. Before removing the inside bearing housing, you must drain the transmission oil, this holds 11 gallons of 85W140. There are two seals, one standard lip seal inside the housing, see below for the seal part number. The other is a large o-ring on the outside of the bearing housing, made this one myself using 1/8" o-ring stock and super glue. Brake seal info:
Case # 03866AB for $22.21
or
Chicago Rawhide 26209, $8.87 Also crosses to a National seal # 445003 or 5503
Dimensions - 2.625 X 3.623 X 0.4 Remember these brakes are designed to run dry and any oil leakage defeats their stopping power. Sometimes the discs are stuck to the splined shaft. There are 7 carbon steel balls inside each brake assembly. 3 of them are 3/8" and the other 4 are 1/2". I bought new stainless steel balls instead of polishing the old ones. The ones I am using are made of type 440-C stainless, which is almost as hard a carbon steeel. I order them from the McMaster-Carr Company. They have a web site. Balls for brake assembly:
Required: 4 ea) 0.50" and 3 ea) 0.375" Info from McMaster-Carr
9642K49 - 440-C Stainless Steel, Precision Ball 3/8" Diameter, Grade 24, Packs of 10 - $3.50 9642K57 - 440-C Stainless Steel, Precision Ball 1/2" Diameter, Grade 24, Packs of 10, $8.33 When re-installing the balls, do not lubriccate them, these parts should be reassembled dry to work correctly. Part of the reason they are prone to rust. You might be able to get a generic package of automotive drum brake parts from your local auto parts. There may be some parts that may work on the Case SC brakes. (spings, cups, etc) The brakes on yours should be single disc, and are adjusted by jacking up the tire, loosening the three cap screws, and tightening the adjusting pinion until drag is felt when spinning the wheel. Then back it off a turn or so. If you bottom out the pinion and the actuator is fully depressed, new linings are in order. The pinion spins a ring which adjusts the contact clearance of the brakes. Pretty simple really. Hope this helps,
