Shaft and Bearing Removal

Remove the bearing housing drain plug and drain the oil lubricant.

Dispose of all oil in accordance with your local regulations.

Clean and reinstall the drain plug.

Undo the housing bolts and slide off bearing gland and oil seal off the shaft.

Remove the oil seal from the bearing cap.

Remove bearings from the bearing housing.

Inspect shaft, bearings and oil seal for damage and replace if necessary.

It is recommended you replace the oil seal and bearings when you have dismantled the pump

to this stage.

Shaft and Bearing Fitment

Clean the bearing housing, shaft and all components (except bearings).

Press the new bearings on to shaft. Slide the shaft and assembled bearings into the bearing

housing until the outer ring of the bearing seats against the bearing housing.

Press the oil seal into the bearing gland with the spring on the oil seal facing the oil side.

Replace the bearing cap gasket and secure the bearing cap with bolts.

Lubricate the bearing housing with SAE-30 oil. Check oil level through site gauge whilst filling.

Fill over site glass

Seal Installation

Clean the seal cavity and shaft. Inspect the stationary seat bore in the seal plate for dirt, nicks

and burrs. Remove any that may exist.

A new seal assembly should be installed anytime the old seal is removed from the pump.

If the sealing seat was removed, install the sealing seat gasket.

Position the sealing seat over the shaft and secure it to the bearing housing with bolts and

washers.

For ease of installation of the seal, lubricate the shaft sleeve and external stationary seat o-

ring with small amount of oil. Slide the seal assembly onto the shaft until the external

stationary seat o-ring engages the bore in the seal plate

Clean and inspect impeller (refer Impeller Installation).

Install the full set of impeller shims provided with the seal, and screw the impeller onto the

shaft until it is seated against the seal.

Continue to screw the impeller onto the shaft. This will press the stationary seat into the seal

plate bore. As the stationary seat becomes fully seated the seal spring compresses, and the

shaft sleeve will break the nylon shear ring. This allows the sleeve to slide down the shaft until

seated against the shaft shoulder.

Continue to screw the impeller on to the shaft until the impeller, shims and sleeve are fully

seated against the shaft shoulder.

Measure the impeller to seal plate clearance and remove impeller shims to obtain the proper

clearance as described in impeller installation and adjustment.

Lubricate the seal assembly with SAE30 oil. Fill cavity with lube oil.
