7. Lift the pump housing off from the cam assembly.
8. Remove the shaft wave spring and shaft bearing.
The bearing might be retained in the sun gear hub. Be careful not to lose it
as it has a loose fit and may fall out.
Use the following instructions and Figure 5-5 to reinstall the pump cam assembly ()
into the booster pump assembly ():
1. Put the pump cam assembly () on a 5-inch support block on a flat-work surface
with the pressure shaft and planetary gears positioned upwards.
2. Install wave spring over the pressure shaft, then install the shaft bearing.
3. Slowly lower the booster pump assembly () onto the pump cam assembly ().
Align the planetary gears with the sun gear () and the outer gear ring ().
To align the gears, rotate the gears with a rubber tipped pry tool as
the pump cam assembly is lowered. The pump cam assembly fully
seats in the booster pump assembly housing when all five gears are
properly aligned.
4. Remove any temporary plastic spacers if necessary and install the pressure shaft
retaining clip and supply fitting. Turn the assembly over and place on rubber feet on
work surface.
5. Put the upper-shaft mount plate () on the top of the booster pump assembly
housing (), being sure to first place lock washers between the plate and the
booster pump housing. The milled lip faces down towards the cam assembly.
6. Install the four inner 3 mm screws () and lock washers () to secure the upper
shaft mount plate () to the upper shaft bearing hub.
