Checking Oil Level
The oil level in the gearbox must be maintained at the recommended level to ensure
efficient operation. Too much oil causes heating from the oil churning. Too little oil
causes heating from lack of lubrication.
To check the oil level:
1. Remove the plug on the side of the gearbox nearest the front of the GrainVac (see
Figure 5.24).
Figure 5.24 Plugs for Walterscheid (red) and Star (black) Gearboxes
2. The oil level should be high enough to allow the oil to come up to the lower edge of
the front side hole when mounted at 45° angle. If required, add oil by removing the
vented fill plug on the top of the gearbox and pouring oil into that hole.
3. Replace the plug(s).
Cleaning Reservoir Breather
The vented fill plug on top of the gearbox contains the breather for the reservoir (see
Figure 5.24).
Important: This breather must function properly to prevent a pressure build-up that will cause the
seals to leak. The breather should be cleaned annually and more frequently in very
dusty, dirty operating conditions.
To clean the breather:
1. Remove the vented fill plug.
2. Soak the plug in good solvent for 1 hour.
3. Blow out the breather passage of the plug with compressed air to remove any dirt
accumulation to ensure that it is open.
