TVR E6333 RG
Timing chain tensioner
Upper timing chain tensioner for all TVR Speed 6 engines. This is the large tensioner for the upper timing chain in the TVR Speed 6 engine. This is a direct replacement for the earlier welded shoe type tensioner and the later all plastic tensioners, and is made from a very high grade nylatron. Nylatron is a modified nylon based plastic containing molybdenum disulphide to enhance its bearing and wear behaviour without impairing the impact and fatigue resistance of the nylon material. For a timing chain tensioner this is the ideal material as it is extremely tough whilst being very slippery due to the inbuilt molydenum disulphide lubricant. Upper timing chain tension is adjusted via the adjusting shaft just below the cam cover on the front upper righthand side of the TVR Speed 6 engine timing chain cover. It is essential that the timing chain tensions are adjusted whilst the engine is hot due to the differential in expansion coefficients between the aluminium block and steel timing chains.Not currently in stock.
