SUBJECT: WATER SPRAY PUMP FAILURES ON LARGE DOUBLE DRUM COMPACTORS
PROBLEM:
The location of the water spray pump in each bumper allows water to run down off the drum and onto the pump. The pump failures are from water intrusion in the motor.
SOLUTION:
Refer to Special Instruction REHS2137 for installation procedure. A new water spray pump is available that has improved water intrusion resistance. The new pump has added o-rings in the motor assembly to better seal the motor. A piece of rubber cover part number 246-1109 should be installed just above the water spray pump. The rubber cover is needed to prevent the constant dripping of water coming off the drum. The CB-434D and the CB-534D mount the water spray pumps in a different location and do not require the rubber cover.
