Disassembly
Remove the planet gear shafts by driving the roll pins into the center of the shafts, then push the shafts out of the planet carrier while supporting the planet gear.Each gear contains two (2) sets of twenty (20) loose bearing rollers, separated by a bearing spacer. Carefully remove the rollers and spacers for inspection. Thoroughly clean all parts and inspect for damage or abnormal wear, as defined in the "Intermediate Planet Carrier Service" section of this manual.Assembly
Support the planet gear on one of the thrust washers and install twenty (20) rollers at the lower end of the bore. A light coating of grease in the bore and on the rollers will aid retention of the bearing rollers in the bore during assembly. Install the bearing spacer, then install the remaining twenty (20) rollers in the upper end of the bore. Repeat this procedure for the remaining planet gears.Move the gear assembly and the supporting thrust washer into place in one of the planet gear openings in the carrier. Carefully slide the gear and washer into alignment with the planet shaft bore. Install the second thrust washer on the upper side of the gear.Slide the planet shaft through the carrier assembly, into and through the gear assembly and thrust washers.Carefully align the roll pin hole in the carrier with the hole in the planet shaft and drive a new roll pin into place. Always use new roll pins. Approximately 1/2 of the roll pin should engage the shaft and 1/2 should engage the carrier.Make certain the roll pin is slightly recessed in the carrier and stake into place as described in the "Intermediate Planet Carrier Service" section of this manual.
