3.3.3 Oil Draining
The oil used in the back end gearbox is a life-long lubricant. It only needs to be changed when an oil seal(s) is
replaced. The amount of oil needed for each back end gearbox is 44.8 ounces. When draining the oil from the
gearbox, take adequate precautions to collect the waste oil and prevent it from dripping onto the work area.
Tools Required
6mm Hex Wrench Funnel
17mm Wrench Waste Oil Container
9/16” Wrench 9/16” Socket and Ratchet
1. Run the sweep to the 1
st
Guard position.
2. Lock out and tag out the pinspotter in accordance with your bowling center’s procedures.
3. Unplug the gearbox motor’s electrical connector.
4. Disconnect the distributor drive shaft and remove the belts from the gearbox pulleys.
5. Remove the motor from the gearbox.
6. Unbolt the gearbox from the mounting plate and remove the gearbox from the machine.
7. Perform a visual check of the gearbox looking for leakage and/or inappropriate oil level.
8. Unscrew and remove the upper vent plug and its washer with a 17mm open wrench.
9. Position a funnel below the gearbox drain plug and then place the small end of the funnel into a waste
container.
10. Unscrew and remove the lower drain plug from the gearbox with a 6mm hexagonal wrench. The oil
used in the gearbox is thick and will drain slowly. Secure the funnel in place, as needed, while the
gearbox is draining. Tilt the gearbox to allow it to drain completely.
11. Inspect the waste oil for metal filings. Significant quantities indicate excessive gear wear and may
warrant further inspection.
12. Wipe away any oil from the threads of the drain opening and install a NEW drain plug. DO NOT use the
old drain plug to prevent possible oil leakages because of wearing/damaging of thread sealing paste.
New drain plugs come with thread sealing paste already on them. Tighten to 80 in-lbs.
13. Go to Section 3.3.8 – Oil Filling if refilling oil.
Caution! Oily rags can be a fire hazard. Dispose of them in an approved metal container only!
