Planetary Gear Section Removal
The planetary section can be removed from the marine gear housing without disconnecting the marine gear from the engine. If it is necessary to remove the planetary sun gear drive shaft, the top shaft must be removed from the housing.1. Match mark the propeller drive flange (4) and the mating flange and remove propeller flange (4).

Disconnect oil hose (2) from the control valve and remove oil manifold (5) and the control valve as a unit.4. Install a lifting eye in the tapped hole in the top of the housing. Remove all of the retaining bolts and use two forcing screws in holes (6) to separate the planetary gear section from the main housing. The planetary gear section weighs approximately 1250 lbs. (567 kg).

11. Retainer. 12. Drive shaft.5. Remove the bolts, lock and ring (8) from the drive shaft and remove planetary drive sun gear (7). The gear is not a press fit on the splined shaft. There is a spacer behind the gear.If it is necessary to remove the planetary sun gear drive shaft the complete clutch and top shaft assembly must be removed. See the topic, TOP SHAFT REMOVAL.6. After the top shaft is removed, remove oil tube (9) and bracket (10). The short oil tube may be in either the bracket or the end of drive shaft (12).7. Remove the bolts, lock and retainer (11) from drive shaft (12).8. Remove the drive shaft (12) through the planet section opening in the housing.

1. Install drive shaft (12) in the lower shaft. Tighten and lock the bolts through retainer (11).2. Insert the short oil tube in the end of drive shaft (12) and install bracket (10) and oil tube (9).3. Install the spacer and sun gear (7) on drive shaft (12) and tighten and lock the bolts through ring (8).4. Thoroughly clean and dry the planetary gear section-to-housing mounting surfaces. Apply 7M7260 Gasket Material on the clean dry surface and install the planetary gear section.5. 7M7260 Gasket Material is used when installing oil manifold (5) and oil pump (1). Make certain the piston ring-type seals, on the oil pump drive end of the top shaft, are not broken when installing the oil manifold. Install filter assembly (3) and connect oil hose (2).6. Install propeller drive flange (4) by aligning the match marks on the two flanges and installing the bolts and nuts.Planetary Gear Section Disassembly
