Planetary Gears and Gear Bearings
Use the following instructions and Figure 5-8 to replace a planetary gear (

) or bearing
(items

and

).
1. Remove the chassis and separate the chassis. See “Chassis” on page 5-11.
2. Remove pump cam assembly from the booster pump assembly housing. See “Pump
Cam” on page 5-14.
3. Remove the c-clip (

) that is connected to the bottom of the bearing pin (

).
4. Remove the planetary gear (

) from the bearing pin (

). Leave the wave spring
(

) on the bearing pin (

).
5. Remove the bearings (items

and

) from the planetary gear (

).
Note
Skip to step 8 if the gear does not need replaced. If the gear needs
replaced, continue to the next step.
6. Remove the internal retaining rings (

and

) from the planet gear (

).
7. Install the internal retaining rings (

and

) in the new planet gear (

).
8. Install the bearings (

and

) into the planet gear (

). Use a bench-top press as
required to push the bearings into the planet gear.
Note
Make sure the bearings are pressed into the planet gear to the depth
illustrated in Figure 5-8. If the bearings do not meet the depth
requirements shown, the c-clip will not lock onto the bearing pin.
9. Put the planetary gear (

) on the bearing pin (

) Make sure the wave spring (

) is
installed between the planetary gear (

) and bearing pin (

).
10. Install the c-clip (

) on the bearing pin (

) to hold the assembly together.
11. Put the pump cam assembly into the booster pump assembly housing. See “Pump
Cam” on page 5-14.
12. Put the chassis together and put into the case. See “Chassis” on page 5-11.
