PUMP UNIT - 5-17

Shimming Procedures

NOTE: Pinion gear shimming and backlash proce-
dures must be preformed when any of the following
components have been replaced:

a. Jet Drive Housing

b. Pinion Gear

c. Pinion Gear Bearing Assembly

d. Pinion Shaft Housing

e. Impeller Gear

f. Impeller Gear Bearing Assembly

g. Impeller Shaft Front Cover

NOTE: Shims are color coded to represent different
thicknesses. These color codes apply to both pinion
housing shims and impeller cover shims.

Red

.002 in. (.05 mm)

Beige

.004 in. (.10 mm)

Blue

.005 in. (.127 mm)

Frost (Clear)

.0075 in. (.19 mm)

Brown

.010 in. (.25 mm)

Yellow

.020 in. (.51 mm)

1. Install original shims on pinion shaft housing.

Install O-ring on pinion shaft housing.

NOTE: If original shims are not available, start with
.030 in. (.76 mm) shims (three brown colored shims).

2. Install pinion shaft assembly into drive housing

bore. Torque screws to 180 lb. in. (20.3 N·m).

28271

3. Rotate pinion shaft ten revolutions to properly

seat roller bearings.

4. Insert Pinion Location Tool (Special Tool

91-824890) in drive housing.

NOTE: Carefully inspect location tool to make sure it
is seated in drive housing bearing.

5. Insert feeler gauge through hole in pinion loca-

tion tool between gauging surface of tool and
flats on bottom of pinion gear teeth.

IMPORTANT: The correct clearance is .025 inch
(0.64 mm).

6. Use .025 inch (.064 mm) feeler gauge as a start-

ing thickness. Adjust thickness of feeler gauge
until a slight drag is felt as gauge is drawn out be-
tween gauging surface of tool and pinion gear.

NOTE: Once the thickness is determined, the differ-
ence between feeler gauge thickness and .025 inch
(0.64mm) required clearance  must be either added
or subtracted from the total thickness of shims be-
tween pinion shaft housing and drive housing.

•

Remove the screws securing the pinion shaft
housing assembly to the drive housing. Lift as-
sembly out of the drive housing.

•

Adjust shim thickness as required.

7. Install seal protector, Special Tool 91-850233,

on impeller shaft. Install impeller shaft in drive
housing, then remove seal protector.
