Description
Overview:
The Cylinder Head - Robin Part - RB20B 13001 00 is a robust replacement head for small air‐cooled petrol engines found in construction and garden machinery. Made from durable cast aluminium alloy, it bolts to the cylinder to close and seal the combustion chamber, maintaining correct compression for reliable starting and efficient running. Precision-machined faces and threads support a sound seal with the head gasket and spark plug. Suitable for equipment such as plate compactors, generators, pumps, tillers and mowers powered by Robin/Subaru engines, including RB-series units such as RB20B. Built to handle heat cycles and vibration on site, this part restores performance when the original head is worn, warped, cracked, or leaking.
Key Features:
- Durable cast aluminium alloy for strength and heat dissipation
- OE‐equivalent geometry to maintain correct compression and fit
- Precision-machined gasket face for a reliable, leak-free seal
- Clean, accurately threaded spark plug boss and bolt holes
- Works with standard Robin/Subaru gaskets, studs and fixings
- Resists thermal cycling to reduce risk of warping or cracking
- Helps restore power, starting, and fuel efficiency by sealing combustion
- Straightforward to install with basic workshop tools, reducing downtime
- Suitable for regular professional use in harsh outdoor environments
- Direct replacement for a damaged or worn cylinder head
Typical Applications:
Used on small Robin/Subaru petrol engines fitted to site and garden machines, including plate compactors, generators, water pumps, turf-care equipment, tillers, chippers, and light construction tools. Ideal for scheduled overhauls or repairs where loss of compression, overheating, or gasket failure has affected engine performance and reliability.
