Is timing chain wear and tear?
Is timing chain wear and tear?
Although the timing chain is made out of metal, it is subject to wear and tear and may break if not replaced as recommended by the factory. The timing chain can start to stretch and wear over time, which will cause the engine’s timing to be inaccurate and cause a few warning signs.
What causes broken guides on the timing chain?
The problem of broken guides on the timing-chain. When the tensioner piston extends, the chain is pulled tight. Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank. Rotating one cam sprocket disturbs valve timing relative to the other side of the engine.
Can a timing chain be replaced without pulling the engine out?
This timing chain cassette can be replaced without having to pull the engine out of the vehicle. But, if the engine has a bad rear chain or guide, or a chain guide has failed and throws debris into the crankcase, you will have to remove the engine to make the required repairs.
What causes a cam sprocket to rotate on a timing chain?
The chain tensioner (2) attempts to take up the excess slack in the timing chain. When the tensioner piston extends, the chain is pulled tight. Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank.
Can a timing chain be replaced on a Ford Explorer?
But it does create an expensive repair for the vehicle owner. Ford issued a TSB for the timing rattle problem and released a redesigned “‘cassette”‘ (the timing chain, gears, guide and tensioner assembly) for the left front timing chain. This timing chain cassette can be replaced without having to pull the engine out of the vehicle.

What happens when you remove the slack on the timing chain?
Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank. Rotating one cam sprocket disturbs valve timing relative to the other side of the engine. This can cause a rough idle can set diagnostic trouble code (DTC) P0300 and codes for lean and rich operation.
Do you need to change your timing chain?
Hello Sue, Your car does indeed have a timing chain. Timing chains do not require any dedicated maintenance. However, changing your engine oil regularly will help extend the life of the chain and all other internal engine components.
