OIL LEVEL CHECKING
The level plug (B) should be removed and filled to the bottom
of the thread. The window (A) allows a quick reference and,
if the oil level is not visible on the window, the level requires
topping up.
OIL CHANGING
Change the oil after the first 50 hours operation, thereafter at
1600 hour intervals or 12 monthly whichever is the sooner.
Oil specifications are shown in the lubrication diagram - see
this chapter. The oil is best drained whilst warm via the remote
drain plug (G) located on the engine pack rear valance. See
the illustration in the preceding auxiliary engine oil chapter.

CYLINDER MAINTENANCE
Periodically inspect the cylinder rods for damage, blemishes or build up of material such as tar,
cement, paint etc. The rods can be cleaned with fine wire wool and/or spirit to ensure long seal life.
When cleaning the machine avoid playing the washdown hose over the body tip cylinder when in
the fully raised condition.

Checking Oil Level
Raise the body and engage the body prop in its
highest position. The level
(A)
should be 10mm
above the lower red line
(B)
on the gauge. It is
important that the correct level is maintained
as under filling can adversely affect the heat
dissipation rate of the oil, whilst over filling can
cause oil to overflow when the body is lowered.
The recommended oil is shown in the lubrication
chart at the end of this chapter.
Alternator and Water Pump Belt Tensioning
The John Deere engines have an automatic belt tensioner so should not require adjustment unless
the belt is replaced - see engine manufacturers handbook for setting information.
