ACTION REQUIRED
NOTE: Please reference Service Mag M0073695 and Special Instructions M0073693. The transmission and torque converter are required to be removed from the machine in order to perform the repair. Next separate the converter from the transmission. If needed refer to RENR8892 Torque Converter from Transmission - Separate. Remove all the shafts from the transmission. If needed refer to RENR8892 Transmission - Disassemble. The 1st/3rd shaft will be replaced. The clutch material and plates from the 1st/3rd shaft will normally be reused. Disassemble the shaft and inspect the clutch plates, friction material, and pistons for damage. Assemble the new 1st/3rd shaft. If needed follow the process in RENR8892 Transmission - Assemble. The parts list includes Case As. 286-9127 for certain later models. Please verify the correct Case As. by Skidder Serial Number. Using the new case, assemble the transmission as defined in RENR8892 Transmission - Assemble. If possible, bench test the transmission prior to installation. |
