Description
Overview:
The Pin, Piston (Robin Part RB524 25001 00) is a precision-engineered component used in small petrol engines commonly found on construction and garden machinery. Made from high-strength steel, it connects the piston to the connecting rod, allowing smooth pivoting under high load and temperature. This reliable link helps keep the engine running smoothly by maintaining correct alignment and reducing wear at the small end of the con-rod. It is suitable for equipment such as generators, water pumps, plate compactors, tillers, and similar machinery using Robin/Subaru engines that specify this part number. Built for durability and a precise fit, it supports consistent engine performance during routine servicing, rebuilds, and repairs.
Key Features:
- Durable high-strength steel construction for long service life under heat and load
- Precision-machined bearing surfaces for smooth movement and reduced wear
- Consistent sizing for engines that specify RB524 25001 00, helping ensure a correct fit
- Supports smooth running by maintaining piston-to-rod alignment
- Suitable for professional workshops and competent DIY users with standard tools
- Helps address small-end play and knocking caused by a worn or scored pin
- Stable under thermal cycling when lubricated with the correct engine oil
- Reliable replacement choice for preventative maintenance or full engine rebuilds
Typical Applications:
Used during engine rebuilds, piston replacements, or repairs where the original pin shows wear, scoring, or play. Typical on small petrol engines powering generators, water pumps, concrete and plate compactors, light construction tools, lawn mowers, tillers, and chippers. Ideal for restoring smooth operation and extending engine life on equipment used in building sites, landscaping, and ground care.
Also known as:
Gudgeon pin, wrist pin, piston wrist pin, piston gudgeon, small-end pin. These terms refer to the same component that links the piston to the connecting rod and allows controlled pivoting within the piston bore in small internal combustion engines.
