Timing Chain
A metal chain performing the same function as a timing belt with greater durability.
Timing chains link the crankshaft and camshaft to maintain valve timing, similar to belts but with longer service life. They require adequate lubrication and tension to prevent slack. Over time, worn guides or tensioners cause rattling noises and misalignment. Replacement involves removing the timing cover and resetting timing marks precisely. Proper maintenance ensures accurate combustion timing and prevents performance loss. Many modern engines use timing chains for reliability under heavy-duty conditions.
