Why are my cam chain tensioners so tight?
In other words the drive is as tight as it will get due to expansion. This will result in a very tiny amount of slack when the engine is cold, but that slack is so little it will be inconsequential as my high miles show it to be.
Why is there no tension control on my Chainsaw?
The spring isn’t strong enough to resist kickback in the chain under crank deceleration, so it isn’t of any value in tension control in that area. What it does is put enough pressure on the rack to push it forward and the pawl clicks in as the chain seats in and cam drive wear occurs… but not always completely.
Can a Honda VTR1000 cam chain tensioner fail?
If the indexing falls in place properly for the mechanical requirements they will work. If it doesn’t they will fail. There is one exception. The Honda VTR1000 can have catastrophic failure of the front cylinder tensioner, which can take out the head and piston – the thing doesn’t just quit working, IT BREAKS!
What’s the movement of a cam chain adjuster?
Less than one full turn of the adjuster bolt, .050″ movement per turn, in four adjustments over 30,000 miles. It is so small a movement if you look at the OEM rack you’ll understand why it is possible to have one go bad and another one go without issue. It’s just not worth the $70 for the automatic one if it fails again.
Are there any problems with the Harley Davidson cam chain tensioners?
Harley, of course, made a fairly expensive upgrade including a new oil pump and hydraulic cam chain tensioners run by the engine oil and re-designed shoes. They also went to a new style chain. The new design is very reliable and as of like 2009 I haven’t heard of any problems with them.
What was the problem with the Twin Cams?
The problem that haunted most of these early twin cam models was the fact that the chains were made with sharp ridges on the outer plates that quickly ate away at the plastic tensioner. being spring loaded, there was always constant pressure on that chain, unlike newer models where the tensioners fill with oil.
How can I see if MY Cam tensioner is bad?
At the cam cover, he reminds us to remove bolts in a star or cross pattern to ease pressure evenly. With the cover open we can see the cam tensioner shoes if the front is in bad shape the rear might be as well. To see the rear without removing the rocker box use a flashlight and mirror.
