I have a whine in my engine????

[Bob Shaw]

Ok, I have a whine in my engine at all rpm's. I recently did some engine repairs ( broken ring) and had the engine apart. It all went back together fine,however, when I tightened the cam chain it seemed the chain was very tight. The whine occurs when stationary or riding and increases with the rpm's. Would the tight cam chain cause this noise???? Any help appreciated....Thanks

OK, I'll be the first to ask, ... is this on your weed whacker or your Corvette?

I followed the Clymer manual. I will check and make sure I've got the spacers in the fam chain idler.

I have not checked my Clymer manual for the procedure, but the chain should not feel tight when you install the tensioner.

Basically, after making sure the timing is correct:
1. Retract the plunger completely
2. Lock it into place with the setscrew
3. Install the tensioner to the cylinder block.
4. Loosen the setscrew, watch the knob on the tensioner to see if it moves.
5. Turn the setscrew in until it contacts the plunger.
6. Turn the setscrew OUT 1/4 to 1/2 turn.
7. Use the locknut to lock the setscrew into place.
8. Use the 19mm nut on the right end of the crank, turn it clockwise, see if the tensioner knob moves as it takes up slack.

The most-common problem is that 'mechanics' tend to leave out step #6.
