Frequently Asked Questions
Are Westwood blade bolts reverse thread or normal thread?
Westwood blade bolts use standard right-hand threads that loosen counter-clockwise and tighten clockwise, exactly like typical nuts and bolts found throughout your mower and in everyday applications. The misconception about reverse threads likely comes from confusion with older mower designs from different manufacturers that occasionally used left-hand threads to prevent loosening from blade rotation, but Westwood has consistently relied on proper torque settings and thread-locking compounds rather than reverse threading to secure blades safely.
Can I reuse old Westwood blade bolts when installing new blades?
Reusing Westwood blade bolts is acceptable for one or two blade changes provided the bolt head shows no rounding or stripping, the threads are clean and undamaged, and the bolt hasn't been over-torqued previously causing thread stretch that reduces clamping force. However, many professionals replace blade bolts with every blade change as insurance against failure since bolts are inexpensive compared to potential damage from a blade coming loose during operation, and bolts that have been torqued multiple times gradually lose their elastic properties making it impossible to achieve specified clamping force even at proper torque settings.
What's the correct order for washers when installing Westwood blades?
The correct Westwood blade assembly order from bottom to top is spindle shaft, blade adapter, blade with cutting edges facing down and wings pointing up toward the deck, special cupped washer with cup facing toward the blade, then the blade bolt threaded into the spindle, though some models include additional flat washers or blade stiffeners that must be positioned according to parts diagrams. The cupped washer is particularly important because its design provides spring tension that helps maintain bolt tightness whilst allowing slight blade deflection when striking objects, and installing it backwards or omitting it entirely can lead to rapid bolt loosening and dangerous blade ejection.
Why won't my Westwood blade bolt come loose?
Seized Westwood blade bolts result from corrosion between the bolt threads and spindle threads especially after exposure to moisture and grass chemicals, over-tightening that has effectively welded threads together through friction heat, or thread-locking compound that has cured beyond normal strength due to age. Apply penetrating oil and allow several hours for it to work into the threads, use a breaker bar rather than a standard ratchet to generate higher torque for initial loosening, and consider using heat from a propane torch on the spindle housing to expand the threads before attempting removal, though be extremely careful not to damage surrounding components.
What torque specification should I use for Westwood blade bolts?
Westwood blade bolt torque specifications vary by model with walk-behind mowers typically requiring 60 foot-pounds whilst zero-turn mowers generally need 35 to 65 foot-pounds depending on deck size and blade weight, making it essential to consult your owner's manual for exact specifications rather than guessing. Under-torquing blade bolts creates dangerous conditions where blades can loosen during operation potentially causing ejection and serious injury, whilst over-torquing damages spindle threads or stretches bolts beyond their elastic limit causing premature failure, so proper torque wrench use is not optional but rather a critical safety requirement.
