Pump Cam and Bearing
Chemicals may seep into the bearing cavity. The pump cam and bearing housing should be cleaned and
inspected periodically to prevent maintenance issues.
1. Loosen the four socket head screws holding the pump head to the motor assembly.
2. Remove pump from motor and clean surfaces of cam and bearing.
3. Examine the sealed bearing. If the bearing does not turn freely or smoothly, replace the bearing.
4. Apply a heavy coating of automotive grease to the area where the piston engages the cam bearing and
reassemble pump to motor.
Piston Seal Replacement
The piston seals within the injection pump motor housing should be replaced periodically to keep chemical
from seeping into the pump housing. The piston seals should be serviced or replaced If chemical begins
leaking from the weep hole on the underside of the pump housing.
Note: New piston seals are supplied in the Pump Seal Kit (P/N 117-0159-987) available through a local
Raven dealer.
CAUTION
Chemical residue or build up may be present on
internal pump components. Wear gloves when
servicing internal pump assemblies.
