Piston Oil Nozzle Cleaning and Inspection
WARNING: This page is about a different variant/trim than selected.
- Clean the nozzle assembly in solution.
- Inspect the nozzle assembly for the following:
- damaged bolt threads
- damaged or cut O-ring seal
- bent nozzle
- A restricted or stuck-open nozzle assembly
- With no oil pressure, the check ball should be seated and not permit flow through the nozzle tube. Using a blow gun, apply air pressure to the inlet portion of the bolt. Air pressure should unseat the check ball and permit flow through and out of the nozzle tube.
NOTE:
The piston oil nozzle assembly is designed to provide oil to the bottom side of the piston for cooling purposes. The internal check ball is held in the normally closed position by the spring until system oil pressure exceeds 20.7 kPa (43.5 psi).
