Exciter Oil
See graphic: wc_gr001152
The bearings in the exciter assembly are splash lubricated and rotate
at a very high speed (up to 5400 rpm). It is important to maintain the
exciter oil at the proper level and change it regularly to ensure
maximum protection.
To drain oil, remove drain plug and tip machine toward drain hole. Use
a suction gun to draw oil out of the exciter case.
When filling, position plate on a level surface and add oil through drain
plug hole until oil is even with bottom edge of threads (a).
Caution: DO NOT overfill exciter case. Excessive wear on engine and
exciter bearings will result.
4.10 Control Circuit Oil
Check oil level in control handle once a week or every 25 hours.
Remove plug from top of control handle. Add oil as required to
maintain proper oil level. Oil level should be at “OEL” mark on outside
of housing. If oil needs replenishing on a regular basis, it may be
leaking past the seals on the pistons. Service the seals on the pistons.
A low oil level may allow air to enter the control circuit. This condition
is normally characterized by the plate’s inability to travel in the forward
direction. Should this occur, bleed the system.
