How tight should a manual cam chain tensioner be?
5-10mm maximum deflection at the centre point seems to be about right. This keeps the cams at their correct timing, but also leaves enough slack for chain tension to increase as the cylinders expand more than the chain. A chain that’s too tight will cause damage, one that’s too loose just rattles/ticks a bit.
Why do I need a tensioned timing chain?
A properly tensioned chain is critical to maintaining the timing between the pistons and the valves. When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.
What happens if your timing belt tensioner is bad?
If the tensioner is bad, it can cause the belt to come loose or cause the pulley to seize, making the belt come off. Knowing some of the signs of a bad belt tensioner can help you to prevent serious engine damage due to a timing belt failure. The timing belt tensioner is used to do just that – keep tension on the timing belt.
What happens when the timing chain loosens on a Nissan?
When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.
Why do I need a chain tensioner on my Harley?
The purpose of this device is to keep the appropriate amount of tension on your primary chain and they do fail sometimes. If that happens, you’ll know and you’ll hear slapping and banging noises in your primary chaincase. You’ll also need to replace the chain tensioner at some point when you get much higher miles on your Harley.

What are the symptoms of a worn out timing chain?
Listed below are 5 of the symptoms of a worn out timing chain. If you notice any of these warning signs, it’s advised you contact a local mechanic as soon as possible to diagnose the exact cause and make appropriate repairs as needed. 1. Engine misfires or runs poorly There are two ways to achieve valve timing in a combustion engine.
What causes oil to separate from the timing chain?
Over time, oil begins to separate as it heats up and is exposed to natural solvents found in gasoline. If the timing chain begins to wear out, small metal pieces can break off the chain and find their way into the oil pan.
make contact with the moving cam chain, back the tensioner bolt out 1/4 turn and tighten the jam nut. (For the finer pitch thread on the APE Pro Series tensioner it is advised to back the tensioner up 1/2 of a turn.) DO NOT over-tighten the cam chain, as cam chain giude damage could occur.
What does a cam chain tensioner do?
Consequently, the timing chain tensioner is a device that places the necessary tension or pressure on the chain to allow it to control the timing chain properly. It usually performs this function through spring tension or hydraulic pressure.
When should I change my cam chain tensioner?
The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.
