Section 11
BEARING HOUSING
The following section should only be necessary if worn or damaged bearings are
suspected.
To Remove
It is necessary to strip the pump assembly in accordance with all the foregoing
sections and drain the bearing housing of oil. After the removal of front and rear oil
seal mounts (Sections 10 and 11), the shaft assembly should be supported and
pressed or lightly tapped with a hide faced hammer forwards from the rear end until
the two front bearings are free and carefully withdrawn from the bearing housing. To
disassemble the drive shaft components, support the oil flinger nearest to the main
bearings on 2 parallel bearers and gently press the shaft from the rear end until the
inner race of the rear bearing is clear of its location diameter. The remaining
components are slide fitted to the shaft.
To remove the front-matched angular contact bearings, support the inner race
adjacent to the largest shaft diameter on 2 parallel bearers and press the shaft from
the front end of the shaft until both bearings are free of the drive shaft. The rear end
outer roller bearing assembly is a slide fit in the housing.
To Rebuild
All components should be clean and free from defects. The matched angular
contact bearing pair should be assembled with the inner race largest faces furthest
apart. Lightly oil or grease the shaft bearing diameter and fit the bearings by means
of a press to ensure squareness during assembly.
The bearings must be pressed fully home to the clamping face on the shaft. The
rear end components may be assembled by hand with exception of the rear bearing
inner race, which has to be assembled by press fit, to clamp all other components.
Finally, insert the shaft assembly into the bearing housing and clamp into position
using to front oil seal housing and O ring as described in Section 10. Complete the
shaft assembly by following Section 11.
