What does it mean when your timing chain rattles?
Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise. Loose chains typically hit the inside of the timing chain cover. A rough running engine may accompany such noises. Test-drive the vehicle and while slowly accelerating listen for any backfiring (popping) noises.
How can you tell if your chainsaw sprocket is worn?
The most common symptom of a worn sprocket can be felt when you rotate the chain manually by hand. This is known as the CHAIN ROTATION TEST. If you have your chain tensioned properly and the chain rotates smoothly one moment and then becomes difficult or loose a moment later, chances are the sprocket has worn teeth.
What is the relationship between speed and sprocket size?
the relationship between speed, chain pitch and sprocket size. The maximum recommended conveyor will be up to 30 metres (100 feet)/minute. Chain speed is a critical influence in smooth conveyor chain operation and extended service life.
How can I tell if my timing chain has slipped?
Listen for any abnormal engine noises, with the engine idling, in the vicinity of the timing chain cover. Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise.
What should the RPM be on a 50 chain sprocket?
IIRC, depending on lube and guarding etc etc etc, chain speed is one of the major govening factors. According to a book I have (Marks’ Standard Handbook) for #50 chain the max RPM is 2200 as long as your smallest sprocket has at least 24 teeth.
What happens when you change the sprocket on a motorcycle?
The lower the chain revolutions, the more frequently each chain link engages the same sprocket tooth, so greater and more uneven the wear. When changing sprockets, you can adjust Chain Links to maintain (nearest to) current Sprocket Centers (eg: to keep motorcycle rear wheel within adjustment range).
What’s the best rpm for a roller chain?
IIRC, depending on lube and guarding etc etc etc, chain speed is one of the major govening factors. According to a book I have (Marks’ Standard Handbook) for #50 chain the max RPM is 2200 as long as your smallest sprocket has at least 24 teeth. If you go to #40 chain with a 24 tooth min. sprocket 3000rpm is the max. Clearly doable.
What is the pitch of a Rev sprocket?
The teeth of the sprocket contact the surface of the bushingswhen the chain is wrapped around a sprocket. Pitchis the distance between the centers of two adjacent pins. Common pitches are 0.25”, known as #25, and 0.375” (#35). The REV Robotics building system uses #25 chain. 1.3 Custom Length Chain
However, when a timing chain is working its way loose, it causes vibration inside and this sounds like a rattling noise when the engine is idling. A rattle always indicates that something is loose and should always be investigated.
When does a timing chain need to fail?
A: As a general rule, if an engine has a timing chain and the oil was changed on a regular basis, the timing chain should last the lifetime of the engine. Timing chains can fail prematurely if the tensioners that hold and guide the chain fail, although usually there will be some engine noise or poor performance prior to the chain failing.
How many miles on chain?
The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem. Issues with the chain are pretty common in high mileage vehicles, so if you are driving an older vehicle, or one with a lot of miles, it is best to be on the lookout for symptoms of the timing chain going bad or failing.
Where do I find the timing chain information?
You can find this type of information in the service manual for your vehicle. In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.

When to see a mechanic about your timing chain?
Issues with the chain are pretty common in high mileage vehicles, so if you are driving an older vehicle, or one with a lot of miles, it is best to be on the lookout for symptoms of the timing chain going bad or failing. If you do start noticing problems, or your vehicle, contact a certified mechanic to have your timing chain replaced.

How does the Nissan timing chain settlement work?
Under the settlement, affected owners and lessees are entitled to partial reimbursement for money spent in connection with the diagnosis of, repair to, or replacement of the primary or secondary timing chain systems or components. Alternatively, those owners and lessees may receive a voucher to be used toward the purchase of a new Nissan vehicle.
