Description
Overview:
The Throttle Ball Joint for BSA 320cc and 420cc industrial engines is a small but critical linkage component that transmits smooth, precise movement from the throttle lever or governor to the carburettor. This genuine BSA part, OEM No. 86 670, is manufactured from durable metal to cope with vibration, heat, and regular use in industrial environments. As unused old stock, it may show minor tarnishing or storage marks that do not affect function. Designed specifically for BSA stationary and industrial engines, it helps maintain consistent throttle response and idle stability, reducing slack in the linkage. It is well suited to routine servicing or refurbishment work on BSA 320cc and BSA 420cc power units used across a wide range of site and workshop equipment.
Key Features:
- Genuine BSA part for assured compatibility and quality (OEM No. 86 670)
- Metal construction for strength and long service life under industrial use
- Precise joint action supports smooth throttle travel and reliable engine response
- Helps reduce play in throttle linkage to maintain steady idle and acceleration
- Direct replacement for worn or loose joints during maintenance and repair
- Suitable for BSA 320cc and 420cc industrial engines used in fixed and portable plant
- Compact form factor for easy routing within existing linkage assemblies
- Straightforward to fit with standard hand tools and basic mechanical skills
- Unused old stock; cosmetic tarnish may be present without affecting performance
- Supports efficient engine operation by keeping control linkage aligned and secure
Typical Applications:
Used on BSA industrial engines to couple throttle arms, governor linkages, and carburettor control levers. Common in equipment such as generators, pumps, compressors, site machinery, and workshop plant powered by BSA stationary engines. Ideal when restoring engines, replacing worn linkage ends, or resolving erratic throttle response caused by excessive play or misalignment in the control system.
Also known as:
Throttle linkage ball joint, throttle rod end, ball-end linkage, throttle ball socket, linkage ball joint, throttle coupler, control linkage joint, governor linkage joint, carburettor linkage joint.
