This video provides step-by-step instructions for replacing the chain tensioner on Craftsman and Poulan chainsaws. The most common reason for replacing the tensioner is when the chainsaw bar doesn’t adjust when you turn the tension screw and the tensioner, rather than the tension screw, the tension gear, or the adjustment bolt, is worn or damaged.

All of the information for this chain tensioner replacement video is applicable to the following brands: Craftsman, Poulan

Tools used: 13mm socket, large flat-head screwdriver

Step By Step Instructions

1
Before you replace the chain tensioner components in your chainsaw first make sure the engine has cooled and that the on-off switch is in the “off” position.
2
Now use the provided wrench or a 13mm socket to help loosen and unthread the nuts securing the clutch cover.
3
Confirm that the chain brake is disengaged and remove the cover.
4
Note the position of the tensioner pin then use a large flathead screwdriver to fully unthread the bar adjustment screw.
5
With the screw removed, you can pull out the tensioner pin, retainer and bearing.
6
You’re now ready to install the new chain tensioner components.
7
Position the new bearing in the clutch cover.
8
With the beveled edge facing outward, insert the new retainer and thread the new bar adjustment screw through the retainer.
9
Align the new tensioner pin and thread the screw through it.
10
Continue to thread the screw until the retainer locks the screw in place then rotate the screw counter-clockwise to return the pin closer to the center of the screw.
11
To replace the clutch cover, the tensioner pin will need to be inserted into the hole in the chain bar.
12
You will probably need to rotate the tension adjustment screw counter-clockwise a few more times to properly align the pin.
13
With the cover in place, hand-tighten the nuts.
14
Now lift the bar and rotate the adjustment screw clockwise until there is no slack in the chain.
15
Now fully tighten the nuts and confirm that the chain is taut.
16
With the repair completed turn the on-off switch to the “on” position and your chainsaw should be ready for use.
