Description
Overview:
This Valve Spring Cap is a small but critical component for Kohler CS-series petrol engines. Made from durable metal, it sits at the top of the valve spring to hold the spring in position and maintain correct tension, helping the valve open and close reliably. Supplied as a Genuine Kohler part, OEM No. 63 173 01-S, it is engineered to match the original dimensions and finish for a precise fit. It is suitable for engines found in light construction and garden machinery, where dependable performance is essential. Ideal for routine servicing or replacing a worn cap, it supports smooth running and consistent compression. Designed for the Kohler CS10 and CS12 (also used on CS8.5 and CS85 where specified), this cap helps keep the valve train stable and well-aligned.
Key Features:
- Genuine Kohler part for assured fit and compatibility (OEM No. 63 173 01-S)
- Durable metal construction for long service life in high-heat, oil-rich environments
- Maintains valve spring position and tension for consistent engine timing and compression
- Direct replacement with no modifications required, aiding quick, straightforward fitting
- Supports stable valve operation to reduce premature wear of valve train components
- Precision-made to original tolerances for reliable seating on the valve spring
- Suitable for use during head overhauls and scheduled maintenance on CS-series engines

Typical Applications:
Used during cylinder head servicing and engine rebuilds on small Kohler CS-series engines fitted to equipment such as plate compactors, generators, cement mixers, tillers, and garden machinery. Ideal when addressing valve train noise, loss of compression due to spring misalignment, or as part of preventative maintenance to keep engines running efficiently.
