Figure 50. MBP/RSD Pump Shaft
A.
Prepare new pump shaft for installation.
Install pump side bearing on pump shaft.
1.
NOTE
The preferred method of assembly is to heat the bearing and cool the pump shaft to
allow a slip fit. Using a bearing heater, heat bearing to 250
℉
(121 °C) (Do NOT ex-
ceed 8 hrs.). Using dry ice in an alcohol bath, cool shaft to –65
℉
(–54 °C) (Do NOT
exceed 1 hr.). Use appropriate PPE to handle/assemble bearing and shaft.
a)
Lubricate pump shaft and bearing center bore with gear oil.
b)
Configure press bolster plate with opening/bore hole or cribbing so shaft passes
thru bearing. (NOTE: The plate must support the inner race to prevent bearing
damage during assembly, bearing-to-shaft is an interference fit.)
c)
Place bearing on press bolster plate.
