Description
Overview:
The Starter Freewheel (T D Cross) is a genuine JAP component for kick start and hand start systems on classic JAP petrol engines. Built from robust machined steel with a one‐way action, it transfers drive during starting and overruns once the engine fires, helping to prevent kickback and wear. As OEM No. 21761, it is correctly matched to the original drive layout for reliable engagement and release. This freewheel is suitable for common JAP stationary and small plant engines, including JAP 4 and JAP 5, and supports smooth, consistent starting on well-maintained engines. Supplied as unused old stock, units may show minor tarnish or storage marks that do not affect function, making it a practical choice for restoration, repair, and ongoing maintenance.
Key Features:
- Genuine JAP part for assured fit and performance (OEM No. 21761)
- Designed for both kick start and hand start systems on JAP engines
- Durable steel construction for long service life in workshop and site conditions
- One‐way freewheel action supports smooth starting and reduces kickback
- Direct replacement for the original component, aiding straightforward installation
- Compatible with a range of JAP engines used in vintage tools and machinery
- Stable engagement helps protect mating gears and starting levers
- Unused old stock; minor cosmetic ageing may be present without affecting operation
- Suitable for routine servicing, refurbishment, and heritage equipment support
- Helps restore reliable starting performance on period engines
Typical Applications:
Used on JAP engines fitted to classic small plant and stationary equipment such as cement mixers, pumps, generators, saw benches, compactors, and agricultural tools. Ideal for engine rebuilds, restorations, and preventive maintenance where dependable starting is required, especially on vintage machinery still in active service or preserved in collections.
