The Primer Overhaul Kit is intended to renew worn sealing components in a manual engine primer pump used on non-fuel-injected engine installations. Replacing worn primer seals can help restore smooth primer-pump operation during maintenance.

  • Roctexo part number: RX1-05-03637
  • Kit contents: two O-rings, seal lubricant and instructions
  • For maintenance of applicable manual primer pumps

Please confirm primer-pump configuration and applicable maintenance data before installation.

Overview

The kit is replaces the worn O-rings (2) on the primer pump used on non-fuel injected engine installations. The primer seals frequently are not re-lubricated until someone complains the primer isn't working or the engine is hard starting. This is most evident by the pump being hard or stiff to operate. Generally speaking, by the time the pump stops performing, the seals are worn (to the point that lube is of little value) and must be replaced.
