Description
Overview:
Cup A is a small, precision-formed steel cup used on Robin/Subaru single-cylinder petrol engines to transmit drive from the recoil starter to the crankshaft. Commonly referred to as a starter cup or recoil starter cup, it provides the engagement surface for the starter pawls so the engine turns over cleanly. This part is engineered to match the original dimensions for reliable fit and alignment on engines such as the EH09 and EH12, and it is also listed against OEM No. 064-20019-10. Built from durable steel with a robust rim profile, it resists wear from repeated pulls and helps protect the crank end and flywheel hub from damage. Suitable for compact construction and garden machinery powered by Robin/Subaru engines.
Key Features:
- Direct replacement for OEM No. 064-20019-10 with OEM-equivalent dimensions for accurate fit
- Tough steel construction to withstand repeated starter engagement and abrasion
- Helps restore smooth recoil starting and consistent pawl engagement
- Supports reliable starting performance on frequently used site and garden equipment
- Simple to fit using standard hand tools; installs in place of a worn or damaged cup
- Concentric, true-running cup face helps reduce kick-back and pawl slip
- Corrosion-resistant finish for longer service life in outdoor conditions
- Suits routine maintenance or overhaul to minimise downtime on EH09 and EH12 engines
- Compatible with listed Robin/Subaru engines without modification
- Cost-effective fix for hard-starting issues caused by a rounded or scored starter cup
Typical Applications:
Used on compactors, rammers, generators, water pumps, and other light plant and garden equipment fitted with Robin/Subaru engines. Ideal for service departments, hire fleets, and DIY users replacing a worn starter interface to restore reliable pull-start operation.
