1895655000MountDetermining thickness of differential bearing scraper rings
- Calculate thickness "S" of the differential bearing pre-loading thrust ring, using the following formula:S = P - H + 0.12
0.12 corresponds to the recommended interference for the bedding in and pre-loading of the differential bearings.After determining the exact thickness of the thrust ring, try and pick a ring as close to this thickness as possible from the spares provided. If you cannot make up the exact thickness using one or more of the shims provided, fit the next size/s up.
1. Place the differential bearing pre-loading thrust ring(s) in position.
