Description
Overview:
The Spring (Brush) - Robin Part - RB235 70545 08 is a small but vital component used to maintain the correct pressure on carbon brushes in brush assemblies found across many construction and garden machines. Made from durable spring steel, it keeps the brush seated firmly against the commutator or slip ring, helping to deliver steady electrical contact. This supports reliable starting, charging, and power generation in equipment powered by compact petrol engines and electric drive units. The spring is designed for straightforward, like-for-like replacement in existing brush holders, helping to restore consistent performance with minimal downtime. Suitable for tradespeople, DIY users, and maintenance teams, it offers a practical fix when brushes are wearing unevenly, sparking, or losing contact due to a weak or fatigued spring.
Key Features:
- Durable spring steel construction for dependable tension and long service life
- Maintains consistent brush-to-commutator contact to stabilise electrical performance
- Helps reduce arcing and heat, promoting even brush wear and cleaner running
- Supports reliable engine starting, charging systems, and generator output where fitted
- Direct-replacement form factor for an easy fit in compatible brush holders
- Quick installation using standard hand tools to minimise machine downtime
- Suitable for a wide range of small engine and motor applications
- Compact design that fits neatly without interfering with adjacent components
- Cost-effective way to restore efficiency before replacing larger assemblies
Typical Applications:
Used in brush assemblies for small generators, engine starter systems, and other brushed electric components found on compact construction and garden machinery. Common in equipment such as portable generators, light compaction tools, cement mixers, and garden machines that employ brushed motors or starter systems. Ideal for routine servicing when brushes are replaced, or when inconsistent contact, excessive sparking, or intermittent power is traced to a weakened spring.
Also known as:
Brush spring, carbon brush spring, motor brush tension spring, commutator brush spring, generator brush spring, starter brush spring, brush holder spring, armature brush spring. These terms are often used interchangeably for springs that maintain pressure on carbon brushes in small motors, alternators, and starter assemblies.
