How does hydraulic tensioner for timing chain work?
Based on physical design, would expect spring to at least partially release after front of tensioner engages timing chain guide when screwing it into the block. But, given direction of the groove cut into the spring housing, looks like that could never happen. Just want to know how it works.
How long does a new hydraulic tensioner need to be?
New tensioner was installed in compressed state (72 mm long). If I’m interpreting step 31 of the installation procedure document correctly, it sounds like the tensioner needs to be in the active, uncompressed state (85 mm long) after it’s been installed and before firing up the engine.
What does a chain tensioner do for Pontiac?
Category: Pontiac The chain tensioner does provide light tension to keep the chain from slipping the sprocket until the oil pressure builds. The tensioner does not apply a lot of pressure to the guide or it would wear the guide it is just to keep the chain from slapping and being noisy by pressing the guide against the chain.
What does a chain tensioner do for a sprocket?

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.
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!
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.
Is the tensioner a sprung piston or a Sprung Spring?
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. The spring is much too weedy to take the large forces exerted on it by the camshafts (which are accelerated and de-accelerated by the valve springs via the tappets).

How to reset KTM cam chain tensioner reset?
KTM timing chain tensioner reset for installation. Here you can see how CCT can be set up properly for install. You can use a thick washer or the famous “nickel and dime” stack for this operation. Tensioner needs to be in almost fully compressed state when installing it: leave it around 3mm out to lock the inner sleeve in place.
