Replacement single row / simplex timing chain for BMC A-Series engines. This is the standard style timing chain fitted to many small-bore A-Series engines, including 850cc, 948cc, 998cc and 1098cc, as well as some 1275cc engines. Alternative part number: SR52 The single row timing chain was used extensively across the A-Series range, with the twin-row duplex timing gear set introduced for performance applications such as the Cooper S. APPLICATIONS Suitable for many: 850cc A-Series 948cc A-Series 998cc A-Series 1098cc A-Series Some 1275cc A-Series engines Always check your existing timing gears and chain before ordering to confirm the correct setup. TIMING CHAIN OPTIONS For a modern upgrade, see 3H2127EVO. This improved chain uses modern materials and manufacturing technology and is a worthwhile upgrade, particularly for engines running without a timing chain tensioner. The improved chain is designed to resist stretch for longer, helping maintain accurate cam timing. Keeping the ignition and valve timing where it should be can help maintain engine performance, power and fuel economy, making it well worth considering over the standard chain. If your existing timing gears are worn, they should be replaced at the same time. Alternatively, upgrade the engine to a duplex setup with: C-AJJ3323 – Duplex timing gear set MSSK051EVO – Super chain and tensioner kit (A+ type) IMPORTANT TIMING GEAR NOTE The camshaft timing gear originally fitted with tensioner rings, 8G549, has been superseded by the plain cam gear, which is now the only type available. Check your existing timing gears for wear before fitting a new chain. A new chain fitted to worn gears may not provide the desired result. A straightforward replacement for renewing the original single-row/simplex A-Series timing chain setup. Show more
