In this video, Renthal does a great job of showing us how to change chain and sprockets on a dirt bike.
- Always replace chain and sprockets at the same time; do not install a new chain on old sprockets or new sprockets with an old chain. This will lead to premature wear on the new hardware.
- O-ring chains are wider then non o-ring chains. Therefore, when installing an o-ring chain make sure there is clearance between the engine case and the chain. Also check for other close contact points to assure clearance. If the chain is making contact at any of these points the chain will need to be replaced with a non o-ring chain.
- Make sure the rear sprocket is aligned with the front sprocket. The chain needs to travel perfectly straight to avoid premature wear and breaking.
- Use a good grease to keep contact points lubricated to avoid premature wear. Before every outing clean the chain with penetrating fluid (non o-ring chains only) to get the dirt out of it, then re-lube with chain lubricant. Degreaser should not be used on o-ring chains because it will cause damage to the rubber o-rings.
Things to note in this video:
- Torque specs for the front sprocket.
- Correct positioning of a master link.
