BRAKE ASSEMBLY DISASSEMBLY 4. Remove the brake piston (Item 90). Remove and dis- card both sets of piston O-rings and backup rings (Items 86, 87, 88, 89). 1. Install the spring compressor tool as show. If a hydrau- lic press is available, only part A of the tool is required. Tighten the nut above part A or apply hydraulic pressure to slightly compress the spring and relieve load on the retaining ring (Item 94). - Page 24 Carefully inspect both halves of the metal face seal be- tween the motor support/brake cylinder and the ring gear. If the metal contact faces show signs of excessive wear or mechanical damage, or the rubber rings are brittle or damaged, the seal should be replaced. ASSEMBLY 4.

PLANET CARRIER SERVICE OUTPUT PLANET CARRIER 1. The preferred method of removing the planet pin (Item 73), is to first remove the roll pin (Item 79). This can usually be done by using a punch or small pry bar to drive or push the roll pin out of the planet carrier (Item 72). - Page 27 4. Remove the retaining ring holding the sun gear in the planet carrier and remove the sun gear. Thoroughly clean all parts and inspect for damage and wear. The bearing rollers should be examined for any signs of spalling, corrosion, discoloration, material dis- placement or abnormal wear.
