Timing (cam) chains — links and type

Cam / timing chains are specified by pitch/type code and link count. On DID-style listings you’ll see codes like SCA0412A SV and a link count such as 82LE (82 links).

Diagram: count timing chain links and read type stamp on a side plate
Count every link pin-to-pin once around the loop. Read the type on a side plate.
  1. Find the old chain type Look for a stamp on a side plate (e.g. SCA0412). Workshop manuals and OEM part lists also list the cam-chain code for your engine.
  2. Count the links Lay the chain out or count on the bike: one link = one pin. The shop listing “82LE” means 82 links. A wrong count will not fit the sprockets and guides.
  3. Confirm bike + year Same model name can change chain length across years. Send make, model, year (and engine code if you know it).
  4. Tensioners are separate A cam-chain tensioner is not the chain. Order the chain from Timing Chains; ask us if you also need the tensioner.
