WATER PUMP REASSEMBLY<br />
1. Remove all grease from the pump bracket<br />
bearing cavities.<br />
4. Install drive motor mount with grease seal<br />
(lip side OUT) and torque the mount bolts<br />
to 60 ft-lbs (82 nm).<br />
2. Install grease seal in bracket assembly (lip<br />
side IN).<br />
To aid in assembly/disassembly, coat all<br />
fastener threads that are installed into blind<br />
threaded hole with an anti-seize compound<br />
prior to the installation of the fastener.<br />
5. Install slinger on shaft.<br />
3. Ensure upper and lower bearings are<br />
packed with grease and install shaft and<br />
bearing assembly in the water pump<br />
bracket.<br />
6. Install drive motor coupling with<br />
LOCTITE® and tighten set screws and<br />
torque the set screws to 12 ft-lbs (17 nm).<br />
Use care when inserting the shaft into the<br />
pump bracket. Ensure the shaft does not<br />
damage the front seal when installing the<br />
shaft in the pump bracket. Failure to use<br />
caution when installing shaft and inspecting<br />
the seal for seal damage after the shaft is<br />
installed may result in shortened service life<br />
or pump, bearing and shaft damage.<br />
