Frequently Asked Questions
What causes differential noise in Westwood mowers?
Differential noise indicates worn gears creating grinding sounds, low gear oil reducing lubrication, damaged bearings causing rumbling, or broken teeth creating clunking. Whining during turns specifically indicates worn spider gears.
How often should differential oil be changed?
Change differential oil every 100 hours or annually using manufacturer-specified gear oil maintaining proper viscosity and lubrication. Check oil level seasonally; low levels accelerate gear wear causing expensive failures.
What causes differential fluid leaks?
Differential leaks result from worn output seals allowing fluid escape, damaged housing gaskets, loose fill plugs, or impact damage cracking housings. Address leaks immediately; low fluid destroys internal gears rapidly.
Why does my Westwood pull harder one direction?
Pulling during turns indicates worn differential allowing unequal power distribution, damaged spider gears binding, or lack of lubrication increasing friction. Inspect differential oil level and gear condition immediately.
Can Westwood differentials be rebuilt?
Differential rebuilding requires specialised knowledge and parts; replacement often proves more economical than rebuild labour costs. Severely worn gears necessitate complete differential replacement ensuring reliable performance.
