MAINTENANCE MANUAL
GP/146/99. Issue 9. October 2005
Place a new O ring over the protruding main bearing and into the chamfer in the
bearing housing.
With a new oil seal mounted in the seal housing, fill seal lip with LM grease. Locate
the assembly on to the main bearing, engage 6 socket head cap screws finger tight
to ensure the seal housing sits flat on the face of the bearing. Tighten 6 screws
progressively until the tightening torque is 28Nm (21 lbs ft).
Insert a new O ring into the seal wear ring and push on to pump shaft (the outside
lead chamfer leading through the oil seal). Place water flinger on to shaft followed
by high pressure impeller shims and shaft key. Refit pump head per Section 9. If a
new oil seal wear ring has been fitted, it will be necessary to carry out the high
pressure impeller fitting and shimming as described in Section 4. The bearing
housing must be refilled to the correct level with the recommended oil.
