Where is the tensioner on the M60 timing chain?
The timing chain on the M60, M62 and M62TU is tensioned by a single tensioner that acts on guide rails as shown above (the tensioner is part # 20). When I got the new one out of the box it looked like this: Yes, the piston is pushed right inside the cylinder…..so I gave it a squash……. ….and the piston came flying out!
When to replace the timing chain tensioner on a V8?
Replacing the timing chain tensioner is highly recommended to increase the life of the V8’s, in particular the integrity of the timing chain guide rails. When the tensioner wears or becomes gummed up with old oil, the timing chain can slap around destroying the guide rails.
What happens to a timing chain when oil wears out?
When the tensioner wears or becomes gummed up with old oil, the timing chain can slap around destroying the guide rails. The tensioner is a hydraulic device rather than just a sprung piston – the action of the tensioner relies on the condition of the piston and cylinder.
When do you need a timing chain tensioner?
A timing chain tensioner keeps the right amount of tension in the timing chain by using hydraulic pressure or spring tension. Over time, the tensioner can begin to wear and need to be replaced. Signs of a failing timing chain tensioner can include loss of power, vehicle shaking or backfiring, hard starts, or a rough idle.
What happens to timing chain when it wears out?
This is because as the chain wears out, it stretches and the ignition and valve timing becomes more retarded. A worn timing chain, guides or chain tensioner can also cause variety of noises originating from the timing chain cover area of the engine.
Why is my timing chain wearing out on my RX 350?
The timing chain problems are not uncommon, especially in high-mileage vehicles. Similarly to any other moving mechanical components inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil. Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster.
Is the timing belt made of rubber or rubber?
A timing belt is a toothed belt made of high-quality rubber; it runs outside of the engine, covered by a protective cover. A timing chain is made of metal, similar to a bicycle chain. A timing chain runs inside the engine, as it needs to be lubricated by the engine oil.
