Large Chain Breaker
For Breaking Chains:
Applications: For chains from #35 to #530. Not recommended for heavy-duty type chains from #530 to #630
Note: If working on cam chains, and cover chain tunnel with rag to prevent parts from dropping down.
Note: 2.2mm pin should be used on most cam chains.
2.9mm pin should be used on #25 or #35 chains.
3.8mm pin should be used on #428 to #530 chains
(most motorcycle drive chains).
Note: If small 2.2mm tip is used, you must also use the upper and lower guides to prevent breaking tip. Upper guide threads on to alignment bolt, lower guide drops in place in bottom of tool body.
Note: When tightening push bolt against chain link pin, if you donG«÷t feel the tip going down smoothly, check that tip is correctly lined up against link pin. If not, repeat step 4 or you may break pin.
For Installing chains:
1. Rivet tip and anvil must be in place in the tool.
2. Assemble chain with link to be riveted.
Note: Special rivet link pins must be used. Using original pushed out pin is not recommended. Do not attempt to use clip-type connecting link. Pin must be all the way through the chain link. It can be tightened into place by placing chain into tool with tool tip withdrawn and tightening alignment bolt.
3. Position tool over pin to be riveted. Make sure tool tip is withdrawn and tighten alignment tool securely against chain. Tighten push bolt very tight so that rivet tip spreads chain pin. End of chain link pin should be flared so that pin is solidly held in place. Repeat procedure on other link pin.
4. Withdraw tool, remove chain and check that both chain link pins show same spread end marks. Rivets on side plate should be in alignment with side plates.
