Servicing details
JHPU Oil
Change the filter element after the first 5 hours of operation, then every 1000 operational
hours.
Visually inspect oil level and condition daily. Refer to figure: Recommendations for Lubricants and Oils.
The oil used in the JHPU system should meet the requirements of ISO 4406 with a maximum level of
contamination of -/18/15.
Check the oil level on the Saginaw pump filler cap/dipstick.
Top up if necessary with the correct grade oil.
Visually inspect the condition of the oil and replace if discoloured, contaminated or smells unusual.
To replace the JHPU oil:
Remove the filler cap.
Place a suitably sized container beneath the hose connection at the pump.
Clean around the hydraulic fittings.
Disconnect the hose at the pump and drain the oil into the container.
Refit the hose and tighten the hose clip.
Refill the JHPU and oil cooler:
Filter the oil when adding it
Use only oil as specified here.
Fill the pump to the
Max
mark on the dipstick.
Dispose of waste oil in accordance with current regulations.
Alternatively:
Use the oil filler hole to suck oil from the pump using an oil retrieval system.
The oil level should be checked after initial running.
As the hoses fill with oil the oil level will drop in the oil tank and will require topping up.
