Complete Gearbox Protection in One Kit
The Constant Speed Gearbox Maintenance Kit is designed to help maintain and protect the gearbox system in Williams & Hussey constant speed molders.
By combining the three most critical gearbox protection components into one convenient kit, this bundle simplifies preventative maintenance and reduces downtime.
This kit includes:
- (3) Fiber Drives
- (1) Bottle of Gearbox Oil
- (1) Gearbox Gasket
Together, these components help protect internal gears, maintain proper lubrication, and prevent contamination inside the gearbox.
Why These Components Matter
Fiber Drives – Sacrificial Protection
Fiber drives act as the first line of defense in the event of a cutting mishap. Designed to give way under excessive stress, they help prevent costly damage to gearbox gears and internal drive components.
Keeping spare fiber drives on hand minimizes downtime when breakage occurs.
Gearbox Oil – Critical Lubrication
Constant speed molders rely on gearbox oil to provide protection for gears, bearings, and seals. Maintaining proper oil levels is essential.
Failure to use the correct oil or maintain proper levels can result in overheating, worn gears, and premature gearbox failure.
Gearbox Gasket – Oil Containment & Debris Protection
The gearbox gasket provides a reliable seal between the chain guard and gearbox. It prevents oil leaks while blocking dust and debris from entering critical internal components.
A new gasket is recommended whenever the gearbox is removed for service or if oil leakage is present.
Ideal for Preventative Maintenance
The constant speed gearbox maintenance kit is recommended for:
- Routine maintenance
- Gearbox service intervals
- Machines experiencing oil leaks
- Replacing broken fiber drives
- Shops that want spare protection parts on hand
Using genuine replacement components ensures proper fit and long-term reliability.
Discovering Internal Gearbox Damage?
This constant speed gearbox maintenance kit is designed to protect and extend the life of your gearbox. However, if service reveals worn gears, damaged shafts, or persistent oil leakage, additional repair may be required.
