cam chain tensioner

[paulkdx220]

hey,

my manual is a bit vague re: setting up the cam chain tennsion.

can somone explain it.

i'm used to camless engines

It's automatic, it sets the tension as you ride. All you have to do is install it on the engine. That's what the setscrew bit is about. Push the plunger all the way in, set the setscrew to keep it there. Install the tensioner on the engine, tighten the bolts. Release the setscrew 1/4 turn or so to allow the springs inside to work, the plunger slides forward to push the tensioner arm into the chain. The locknut is only to keep the setscrew from falling out at this point.

One it's in place you don't have to touch it until it leaks too much or wears out.

Racers that always use uber high RPMs like to replace them with manual tensioners, but I've never had one fail, they just get leaky after thirty years or so.

Just to add to Toms explanation..You dont reset the screw against the pushrod once you release it onto the chain. You keep it loose that 1/4 turn and just tighten up the jam nut. If you touch the setscrew to the pushrod you defeat the floating action of the tensioner. You may have already assumed that but i thought i would add.

Be sure to follow the procedure for checking the operation of the cam chain tensioner after you install it to prevent any grief. make sure it operates freely before installing. I just replaced the leaking o-ring ($1.00US) on the set screw on my 82 GS750E and it was rather simple.

Yes, , but you meant check its free operation, BEFORE you install it, so you understand the function of lock screw and lock nut. It's so simple, folks get confused!
