Propel transmission scavenger pump may lock up on certain RM-350B Reclaimers. Indications of scavenger pump lock up would be a loss of propel and or rotor transmission engagement functions along with oil spilling from the propel transmission breather.This condition generally occurs at low hour break-in (0-350Hrs).
NOTE: SCAVENGER PUMP LOCK UP CAN BE CONFIRMED BY INSTALLING A PRESSURE GAUGE AT TEST PORT "E" OF Priority VALVE 121-7019. IF SCAVENGER PUMP IS LOCKED UP, PRESSURE WILL BE 750±100PSI.
