*NOTE: Later 4430 model operating arm is retained to shaft with a pin as with 4630 tractors (Fig. 14). This eliminates the heafled pin (Q, Fig. 13).

8. Remove pin (Q) in upper left-hand corner of clutch housing to remove control valve shifter cam shaft out the side of the housing and remove shifter arm (R). Note that the 4630 pin (U, Fig. 14) must be driven out.

9. Remove small hex. bushing from planetary (S) if it did not come out with the clutch shaft.

NOTE: The planetary can be removed from the clutch housing without removing the PTO drive gear.

10. Make a tool with a 1 /4-inch (6 mm) diameter rod at least one foot (300 mm) long. (The rod must be small enough to go through the transmission input shaft.

a. Either flatten one end of the rod and bend over slightly to form a hook;

b} Or, braze a 1 /2-inch (13 mm) OD (max.) flat washer on the end of the rod.

11. Align splines in front sun gear with transmission input shaft.
