Description
Overview:
The Cam Shaft Gear for Robin is a precision-machined metal gear used in the valve timing system of small petrol engines. It links the camshaft to the crankshaft to keep valve opening and closing in correct synchronisation, which is essential for smooth running, power, and fuel efficiency. Built from durable metal for long service life, it is suitable for a wide range of Robin/Subaru engines found in construction and garden machinery such as generators, plate compactors, pumps, and mowers. Referenced by OEM No. 228-33221-11, this gear is designed as a direct replacement to restore timing accuracy and eliminate wear-related issues. It offers a reliable fit and consistent performance for professional users and DIY maintenance, reducing the risk of mis-timing, poor starting, or uneven idle.
Key Features:
- Direct replacement matching OEM No. 228-33221-11 for a straightforward fit
- Robust metal construction for resistance to wear and extended service life
- Accurate tooth profile to maintain precise valve timing and engine efficiency
- Helps restore smooth starting, stable idle, and consistent performance
- Suitable for many Robin/Subaru small engines used in site and garden equipment
- Compatible with petrol four-stroke timing layouts where a cam gear is specified
- Designed for easy installation to minimise downtime during repairs
- Supports preventative maintenance schedules and reduces repeat failures
Typical Applications:
Used in Robin/Subaru-powered equipment across construction, landscaping, and grounds care. Typical examples include site generators, plate compactors, water pumps, pressure washers, lawn mowers, and small plant. Replacing a worn camshaft gear restores timing integrity, helping prevent misfires, loss of power, and increased fuel use, while prolonging engine life.
Also known as:
Cam gear, timing gear, camshaft gear, camshaft sprocket, valve timing gear, cam wheel. These terms describe the same component responsible for timing the camshaft relative to the crankshaft in a four-stroke engine.
