The chain is not a huge issue, but the sprockets are. When a chain wears, the sprockets suffer the same about of wear. If you just change the chain, the new one will have seriously shortened life as it wants to wear out to the level of the old sprockets.
This is not a do it yourself job, specifically the front sprocket.

Timeing chain tensioner replacement on a 2005 nissan quest sl

Improve the FixYa experience for everyone by voting. I want you to let me know if the solution(s) suggested were of any value. Constructive criticism is welcomed.


I'm Ben and -- hopefully -- I can provide some meaningful assistance.

I'm not certain that I fully understand your problem. Therefore, I'm probably provide more information than you'll need.


A timing chain tensioner for your quest will cost $59-$75. The tensioner sits behind a small cover on the front of the engine. It;s difficult to reach but the replacement should take no more than 2 hours.
  1. Move power steering and coolant/antifreeze resevoirs out of the way for access .
  2. You may have to use a c-clamp to hold the guide and chain up out of the way.
  3. The difficult part is installing the tensioner without pulling the plunger stopper pin.

The following link is a tutorial on how to replace the chain, guide and tensioner and covers everything in far more detail than I'm permitted here. CLICK HERE

The following video should be of some additional assistance.

Popping noise coming from front sprocket when wheel is turned on 01 suzuki gsxr 600

hi it sounds like your front sproket is really worn and hooked when you turn the chain its not releasing the links smoothly ,replace it with a new one and check the condition of your chain it may be worth replacing a complete chain and sproket set as running a bike with a worn front sproket could lead to a back wheel locking up at speed if the chain jams

I need someone to tell me how to replace the timing chain on a 04 Honda rebel. I have tried and tried to get someone somewhere that knows how and just can't find anyone.

The cam chain is a endless chain. You will have to split the cases to replace it forcing you to remove the engine from the bike.
I have a 2005 rebel with 38,000+ miles on it and still have the factory chain. What makes you replace it. Unless there was mechanical damage or you put a lot of mile on it you shouldn't need to replace it. It also has an auto tensioner in it so you don't have to adjust the cam chain.

If you take the valve cover off you will see the top of the chain. try to wiggle the chain. If there is no freeplay between the chain and sproket then your chain should be fine. If the chain pulls away the sproket then it needs replaced.

Rebels don't have oil filters so it is important you change your oil often. the drain plug has a little "crush" washer on it. that MUST be replaced every time you change your oil. You can pick one up at a motorcycle shop for about 90 cents. If you reuse or remove the crush washer eventually your threads will strip and/or the blot will back out when your going down the road. and the drian hole is positioned where the oil will leak out right under your rear tire.

Timing chain noise 2005 cavalier 2.2 ecotec

Just the guide is probably making the noise. So either a new guide or a new chain. I would start with guide first, unless chain looks loose or cruddy
