Description
Overview:
This Piston Ring Set 0.25 (reference RB228 23502 07) is a service part for small petrol engines used in construction and garden machinery. Made from durable, heat‐resistant ring-grade alloy, it restores the seal between the piston and cylinder to reduce blow‐by and maintain compression. The result is steadier idling, easier starting, and improved power with better fuel efficiency. The 0.25 oversize specification is intended for engines that use an oversize piston after a cylinder re‐bore. Suitable for Robin/Subaru applications where 0.25 oversize rings are specified, commonly found on generators, water pumps, compactors, and garden equipment. Manufactured to OEM‐equivalent dimensions and tolerances to support dependable fit and long service life during routine rebuilds or corrective maintenance.
Key Features:
- 0.25 oversize ring set for engines requiring oversize parts after a re‐bore
- Precision‐machined faces and tight tolerances for reliable compression sealing
- Heat and wear resistant construction for sustained performance under load
- Helps recover starting, power, and fuel efficiency by reducing blow‐by
- Supports correct oil control to minimise smoke and oil consumption
- Stable, consistent operation across typical on‐site and garden workloads
- Suitable for Robin/Subaru small industrial petrol engines in plant and horticultural tools
- Straightforward to fit during routine overhauls using standard piston ring tools
- Supplied to OEM‐equivalent specification for a dependable replacement
Typical Applications:
Used during engine rebuilds and scheduled maintenance on small petrol engines powering plate compactors, generators, water pumps, lawn and garden machines, and similar equipment. Suitable when addressing low compression, hard starting, loss of power, or high oil usage. Appropriate for both professional plant maintenance and DIY servicing to extend engine life and maintain reliable day‐to‐day operation.
