What Is A Cam Chain Tensioner

The cam chain tensioner maintains proper tension on the chain and in the V60 is a hydraulic tensioner that requires no maintenance. There is a complete list of maintenance items in the owners manual.

How do you know if your cam chain tensioner is bad?

Symptoms of a Bad or Failing Timing Chain Tensioner Engine may stall or run rough. Noise in the front of the engine (a rattle or rumble, associated with engine speed) Check Engine Light may illuminate and set misfire, camshaft sensor, and crankshaft sensor codes.

How much does it cost to replace a timing chain tensioner?

The average cost to replace timing chain tensioner is around US$1000 to US$1600. In which the service is around US$600 to US$1000 while aftermarket auto parts are estimated between US$450 and US$600.

When should I change my cam chain tensioner?

What happens if your timing chain tensioner is bad?

When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise.

What year did Harley fix the cam chain tensioners?

Regardless, the cam chain tensioner issue occupied more space in Twin Cam forums than the cost of gas debate. All of which in 2007 resulted in H-D modifying the part with a hydraulic actuated tensioner.

What does a bad cam chain tensioner sound like?

Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. Such a noise will reveal a loose timing chain hitting the inside of the timing chain cover every time it rotates. You might also hear a metallic slapping noise.

What causes timing chain tensioner failure?

A timing chain can break with either too much or not enough tension. This can result in the chain “slapping,” leading to premature fatigue. A chain with too much tension can also fail, as it is placed under excessive stress. Tension increases friction and heat in the chain, which can result in failure.

What is the Mini death rattle?

A weak tensioner can cause your MINI to develop the dreaded cold start (death) rattle. This is where the chain is not under the correct amount of tension and is free to rattle around against the plastic chain guides. The noise can be reminiscent of a diesel tractor on startup and does not sound particularly healthy.

What are the signs of a timing chain going bad?

Common signs of a faulty timing chain include engine misfires, metal shavings found in the oil, and rattling sounds from the engine while idling. Engine misfires or runs poorly. Metal shavings found in the oil. Engine won’t start or fails. Check Engine Light is on. Engine rattles while idling.

What happens if you don’t replace timing chain tensioner?

When the tensioner goes bad, the chain may appear loose within its connected parts, causing it to fail. Again, the timing chain failure causes the engine to malfunction, and in extreme cases, the car would not run.

Is it worth replacing a timing chain?

Unless there is a specific problem, the timing chain normally needs to be replaced between 80,000 and 120,000 miles. If you drive an older vehicle, or one close to 100,000 miles, you should have it replaced or at least become aware of the symptoms of a failing timing chain.

1. Grinding or squeaking noise from the belts or tensioner. The most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started.

What does it sound like when timing chain is going out?

When you hear a rattle or unusual sound, it means that there is a problem with the engine. When the timing chain is loose, it can cause a vibration in the motor resulting in a rattling noise as the engine idles or when starting. If you hear a rattle, it means something is loose and needs to be fixed before it breaks.

What are the bad years for Harley Davidson?

1981 was a notoriously bad year for Harley, produced while the company was still run by AMF. It’s a neat-looking track-focused bike, but that’s about it. The XR-750 was notoriously underpowered, unreliable, and most of all had balance issues that could easily cause the rider to lose control of the bike.

How long do cam chain tensioners last?

I don’t object to spending the extra money on any of the cam design upgrade options (hydraulic, gear drive, etc), but the truth is, you can leave the existing design in place, replace the tensioners with new ones and expect to get another 40K-50K miles out of them. For most people that’s 5-10 years of service.

What is the most reliable Harley?

Unfortunately, many past Harley-Davidsons suffered reliability and quality-control issues, which made them expensive to own and maintain. But there’s one used Harley that has a particularly bulletproof reputation: the Evolution-engine Harley-Davidson Sportster.

Why do I hear a rattling noise under my car?

Rattling from under your car– This can be caused by loose parts such as your exhaust system. Squealing wheels while braking– Causes range from small, such as dirt on the brake pads or rotors, to serious, such as worn pads. This causes damage each time you apply the brakes.

Why do I hear a rattling noise when I accelerate?

if you hear a pinging or rattling sound when accelerating, low-octane fuel could be the cause. pinging (also called pre-ignition or detonation) can also be the result of carbon deposits, a bad knock sensor, overheating or incorrect ignition timing.

When I press on the gas I hear a rattling noise?

You usually hear this noise when accelerating the vehicle. Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.

Can I drive with a bad tensioner?

Driving with a bad belt tensioner is unsafe since the tensioner is meant to guarantee ample tension that powers accessories. Wear on the belt tensioner will eventually cause the belt to slip, generate loud noise, and also create an unsafe level of heat along the accessory pulleys.
