How is timing chain and gear set replacement?
Replacement involves removal of the timing cover, timing chain tensioner, timing chain, timing gears and timing chain guide rails. These are all replaced during a timing chain service. Timing chain guides are typically held in place by pins or fasteners, and one end will typically be left to pivot freely with the timing chain.
How can I tell if my timing chain has stretched?
In cases where the timing chain has stretched, you may experience a rattle from the engine or a lack of responsiveness when accelerating. In extreme cases, the engine may stall while driving or not start. Replace worn timing chain guides at the same time as the timing chain. Replace balance shaft chains along with the timing chain if equipped.
What happens if you have a worn timing gear?
A worn timing gear may become noisy or it may show no symptom at all. They rarely fail completely but if they do, you may have other serious damage to the engine. At the very least you will be stranded. So a worn timing gear should not be neglected. Step 1: Jack up the car. Make sure the car is in Park, or in first gear if it is a manual.
How does a chain tensioner work on a timing chain?
A timing chain is kept under proper tension by a chain tensioner. A chain tensioner could be operated by a spring-loaded mechanism or oil pressure. Timing chain, tensioner and chain guides. See timing chain animation. Chain guides and silencers are used to keep the timing chain from vibrating. All these components wear too.
When do I need to change my timing gears?
Timing gears are lubricated by engine oil, so regular oil changes are required to keep timing gears in good condition. They are only accessible when the timing cover is off for a timing belt or chain repair/replacement, and should be checked at that time.
When do I need to replace my timing chain?
Timing chains and timing gears are meant to last the life of the vehicle, and typically never need replacement for maintenance purposes. Timing chain failures tend to include the timing chain guide rails or the timing chain tensioner, but the timing chain requires replacement only when broken or stretch too far to maintain proper camshaft timing.
What’s the best way to change a timing belt?
The important thing is to make sure that your timing belt is as tight as it should be. Drive out the crankshaft seal with a hammer and punch. This is the rubber seal around the crankshaft and the timing cover. Tap the new crankshaft seal into the timing cover. The seal should be seated into the correct place on the timing cover.
How do you change the timing cover on a car?
Drive out the crankshaft seal with a hammer and punch. This is the rubber seal around the crankshaft and the timing cover. Tap the new crankshaft seal into the timing cover. The seal should be seated into the correct place on the timing cover. It will seal when the cover is bolted onto the engine. Coat the seal with oil.
