Planetary Geartrain
NAG1 TRANSMISSIONPlanetary Gear Train
DISASSEMBLY
1. Remove upper two visible Teflon\e1m(R)\e0m rings (1) (Fig. 201) from output shaft.
2. Remove retaining ring (11), shim (10), thrust needle bearing (9) and thrust washer (8) from output shaft.
3. Remove clutch K3 (7).
4. Remove rear tubular shaft/freewheeling clutch F2 (6) (Fig. 201) from output shaft.
5. Remove rear gear set (5) with integrated tubular shaft of center gear set from output shaft.
6. Remove thrust washer (4).
ASSEMBLY
1. Mount thrust washer (4) (Fig. 202) with the collar pointing towards the planet carrier.
2. Mount rear gear set (5) with integrated tubular shaft of the center gear set on output shaft.
3. Using grease, install lower three Teflon\e1m(R)\e0m rings (1) (Fig. 202) in the groove so that the joint stays together
4. Put rear tubular shaft/freewheeling clutch F2 (6) onto output shaft.
5. Install clutch K3 (7).
6. Mount retaining ring, shim, thrust needle bearing and thrust washer (8 - 11) (Fig. 202).
7. Using grease, insert the upper two Teflon\e1m(R)\e0m rings (1) in the groove so that the joint remains together.
8. Inspect axial play (Fig. 203) between shim (10) and retaining ring (11). Check axial play "S" between shim (10) and retaining ring (1) using a feeler gauge. Clearance should be 0.15 - 0.6 mm (0.006 - 0.024 inch). Shims are available in thicknesses of 3.0 mm (0.118 inch), 3.4 mm (0.134 inch), and 3.7 mm (0.146 inch). Adjust as necessary
NOTE: During the test, apply a contact force by hand to K3 in the direction of the arrow.
