Lifetime Timing Belt Design

GC series, GS series

Honda’s GC and GS engines use the world’s first small engine internal timing belt, designed to last the lifetime of the engine.

Small engine timing belts are usually external and are subject to wear caused by dirt.  Honda’s internal timing belt runs in oil, eliminating the need for conventional drive gears. 

This design:

• Improves lubrication,
• Reduces the weight of the engine, and
• Provides quieter operation.
