Can be two different things. Chain tensioners for bikes with horizontal dropouts are small gadgets that hook over the rear axle and pulls it towards the rear to help keep the chain tensioned. Chain tensioners for bikes with vertical dropouts are like a small spur wheel usually in the position where a rear derailer would have been. These push the chain downwards to keep an even tension on it.
You cannot adjust the tensioner. It is automatic, and takes out the slack of a stretching/aging cam chain. Once the tensioner has fully extended, the only fix is to replace the chain and the part of the tensioner the chain rides on if it is worn.
You just set the cam chain tensioner - give me a break...
The timing chain tensioner bolt sticks out the back left side of the cylinder head. Take the timing chain cover off on the left side of the motor too see the inside to the chain tensioner.
A cam chain tensioner puts pressure on the chain, keeping it taut. If the chain were to not be tight, then it could slip on the gears causing the engine to run rough, or cause engine damage.
You dont, it's an automatic hydraulic tensioner. However eventually the chain and/or tensioner spring will wear out.
I believe the cam chain tensioner on the 400ex is automatic, as with most if not all of the newer quads.
You don't. The YFM225 uses an automatic chain tensioner that helps to take up the slack on the cam chain. If you are getting chain slap, then either the chain is stretched or the tensioner is not functioning correctly. In both cases, the parts should be replaced. You cannot repair a non-functioning auto tensioner, nor can you remove links from a stretched cam chain.
Not really. The top side of the chain is where the tension goes when you pedal, so first it'd only pull the tensioner straight, then you could still have slack on the bottom run of the chain simultaneously.
No, timing chain doesn't need replacing.
With the tensioner installed, you have to push the center of the tensioner piston inward with a screwdriver several times until it releases. When it releases the piston will move outward and push the chain guide tensioner against the chain. If this does not work buy a new one at autozone ($42.00), which is what I had to do. The new tensioner is the same type and works the same way. Vehicle: 1997 Chevy Cavalier 2.4L
The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray
It has an automatic chain tensioner..
