Is there a cure for a chain tensioner?
The cure, says Ford, is to replace the original chain tensioner components with redesigned parts.
What are the different types of timing chain tensioners?
These include two timing chain tensioners F5RZ-6L266-CA, the left hand tensioner adapter F5RZ-6C275-BA, the right hand tensioner adapter F5RZ-6C275-AA, the left hand chain tensioner arm F6RZ-6L253-AA and the right hand chain tensioner arm F6RZ-6L253-BA. The two DOHC timing chains and guide assemblies should also be replaced at the same time.
Do you need to change timing chain on OHC engine?
On OHC engines that use a timing chain, the timing set may also include a chain damper or tensioner. The chain damper, tensioner, guide or rails should also be replaced when the chain and sprockets are replaced because these components play a vital role in supporting the chain and keeping it tight.
When to replace timing chains and guide assemblies?
The two DOHC timing chains and guide assemblies should also be replaced at the same time. As for timing belts, they do not stretch with age, but become weak internally and may fail with no warning. Consequently, a visual inspection of the belt may not reveal much. If the mileage is not known, replace the belt.
Do you need to replace an upper tensioner bolt?
To replace the upper tensioner bolt, you do not need to remove anything. Simply follow steps 10, 48 and 52 to remove and install the bolt. Please do the procedure at your own risk and be ready to make small adjustments while doing them.
How to do timing chain and guides replacement?
The procedure assumes that the transmission, clutch, flywheel, upper intake manifold and other small parts (coilpack, TB, airbox …) have been removed from the car and that other steps necessary to remove these have also been performed (front end of car raised, battery disconnected, etc).
What is the tensioner on a VR6 timing chain?
Each timing chain has a guide rail (curved on the upper chain, straight on the lower chain) and tensioner rail to keep them tight. The lower tensioner rail is a one-piece, spring-driven unit, while the upper tensioner is a two-piece design consisting of a tensioner rail and a separate tensioner bolt.
Is the Dyna manual chain always that noisy?
No signs of obvious wear, no metal shavings on drain plug magnet. Are these chains always that noisy?. PS the reason I mentioned my helmet change is the full face blocks out much more noise. Hard to compare what is noisy to you vs what is noisy to me. Was an ’06 Dyna manual chain adjusted? I know Softail was in 2006.
