Drive Shaft Oil Seal
1. Remove the four (4) 5/16”-18 and the two (2) 7/16”-14 screws to dismantle
the bell housing from the gearbox. (See Figure 6c-1: “20 / 30 FS Series
Gearbox and Bell Housing Overview” on page 117.)
2. Slide the housing from the drive shaft.
3. Remove (press–out) the oil seal and discard. Oil seals cannot be reused.
To replace, order Hale p/n: 296-2220-00-0. Apply a coating of general-pur-
pose grease to the seal to ease installation. (See Figure 6c-1: “20 / 30 FS
Series Gearbox and Bell Housing Overview” on page 117.)

Housing Overview” on page 117.
Drive Shaft and Gearbox Assembly
1. Review heading 6c.1 “General Preparation” on page 115.
2. If the gearbox is equipped with a water manifold, remove the twelve (12) 5/
16”-18 screws and washers and remove the water manifold and gasket from
the gearbox.
If the pump is not equipped with a water manifold, remove the screws and
washers, the gearbox cover, and gasket.
3. Remove the 1/2”-13 nylon locking set screw from the gearbox housing.
(See Figure 6c-1: “20 / 30 FS Series Gearbox and Bell Housing Overview”
on page 117.)
4. With the set screw removed, insert a drift punch into the 1/2”-13 hole and
begin pushing the drive shaft from the gearbox WHILE protecting the drive
gear and possibly the pump-side bearing, from falling out.
5. Once the shaft is clear of the gearbox, remove the drive gear, shaft key, and
possibly the pump-side bearing, from the gearbox housing.
6. Remove the engine-side bearing from the drive shaft.
7. Inspect all parts for excessive wear, chips, scoring or other damage. Repair
and/or replace accordingly.
