Description
Overview:
The Piston Ring Set 0.50 - Robin Part - RB234 23503 07 is a wear-resistant metal ring pack for restoring cylinder sealing on Robin petrol engines. It maintains compression, controls oil, and reduces blow-by, helping engines start reliably and deliver steady power. This set is specified for the Robin EY28 engine and is suitable for machinery commonly used on site and in the garden. The 0.50 designation denotes an oversize of 0.50 mm, intended for use with matching oversize pistons and a correctly rebored and honed cylinder. Supplied as a set for one cylinder, it typically includes compression and oil control rings to renew the sealing surfaces between the piston and bore. A practical choice for planned overhauls or repairs where wear, glazing, or scoring has reduced performance.
Key Features:
- 0.50 mm oversize ring set for use with +0.50 mm pistons and a rebored cylinder
- Restores compression and reduces oil consumption for improved efficiency
- Durable construction for long service life in tough site conditions
- Precision-ground profiles to promote correct ring seating and sealing
- Stable oil control to minimise exhaust smoke and plug fouling
- Consistent performance across heat cycles due to heat-resistant materials
- Accurate to fit the Robin EY28 bore specification when rebuilt to +0.50 mm
- Suitable for routine maintenance or full engine overhauls
- Supports reliable cold starts and smoother running
- Supplied as a set for one piston/cylinder
Typical Applications:
Used during engine rebuilds and repairs on equipment powered by Robin EY28 engines, such as plate compactors, generators, water pumps, and garden machinery. Ideal when a cylinder has been rebored to +0.50 mm or when symptoms such as low compression, hard starting, or increased oil use indicate ring wear. Suitable for preventative maintenance to keep fleet machines operating efficiently.
