Use clean 15W-40 oil to lubricate the water pump shaft.
Use water pump bearing mandrel, Part No. ST-658, to support a new inner bearing. Install the shaft into the
bearing.
NOTE: Push the pulley end of the shaft through the bearing until the bearing is against the large diameter (shoulder) of
the shaft.
Visually inspect the bearing spacer for cracks or damage.
Check the thickness of the bearing spacer.
Install the bearing spacer on the shaft.
Fill both bearings and the cavity of the spacer between the water pump bearings with Chevron SRI grease or its
equivalent.
Use water pump bearing mandrel, Part No. ST-658, to support a new outer bearing. Install the shaft and the
spacer into the bearing.
NOTE: Push the shaft through the bearing until the bearing is against the spacer. Make sure the inner race of the bear-
ing is not overloaded from contact with the spacer. The bearings must rotate freely.
Install a new inner oil seal and a new slinger onto the shaft.
Use seal expander, Part No. 3823885, to install the seal.
Use water pump slinger driver, Part No. 3823816, to press the slinger to the proper location.
Prepare the outside diameter surface of the bearing with Locktiteᮋ Primer T, Part No. ST-1272-13.
Apply a thin film of Locktiteᮋ 609, Part No. 3823718, to the outside diameter of the bearings.
Support the impeller side of the water pump body in an arbor press. Use water pump mandrel, Part No. ST-658,
to install the bearing and shaft assembly in the water pump body.
Install the retaining ring into the groove in the water pump body.
NOTE: The flat side of the bearing retaining ring must be installed toward the bearing.
Install a new outside oil seal, using a mandrel to press the seal in flush with the housing.
Apply a thin film of pipe sealant, Part No. 3375066, to the outside diameter of the new water pump seal.
Support the pulley side of the water pump in an arbor press.
Install a new water pump seal over the shaft.
Use water pump seal mandrel, Part No. 3823815, to push the water pump seal into the water pump body.
NOTE: The use of any tool other than Part No. 3823815 can result in seal damage.
Apply one drop of Locktiteᮋ 290, Part No. 3823682, or its equivalent to the joint between the water pump shaft
and the water pump seal.
NOTE: Do not allow any Locktiteᮋ to contact the seal faces.
Prepare the drive pulley bore surface with Locktiteᮋ Primer T, Part No. ST-1272-13.
Apply a light film of Locktiteᮋ 609, Part No. 3823718, to the bore in the drive pulley.
Support the water pump pulley in an arbor press. Push the water pump shaft into the pulley bore until the pulley
is against the large diameter (shoulder) of the shaft.
Prepare the impeller bore surface with Locktiteᮋ Primer T, Part No. ST-1272-13.
Apply a light film of Locktiteᮋ 609, Part No. 3823718, to the bore in the impeller.
Support the pulley end of the water pump shaft in an arbor press. Push the impeller onto the shaft until the end of the
impeller hub is aligned with the end of the shaft.
As a final inspection, turn the water pump pulley by hand to inspect the bearings for freedom of rotation.
NOTE: If the water pump shaft does not rotate freely in the water pump body, the water pump must be disassembled,
inspected, and assembled again.
