Milwaukee Chain Tensioning Post for 2527-20 and 2727-20
Model Number: 05-89-2001
The Milwaukee 05-89-2001 is a genuine OEM Chain Tensioning Post for the Milwaukee M12 Hatchet Pruning Saw (2527-20) and M18 FUEL Chainsaw (2727-20). The chain tensioning post is the sliding pin component within the chain tensioner assembly that moves forward or backward when the chain tensioner adjustment screw is turned — pushing the guide bar forward to increase chain tension or allowing it to retract when the chain needs to be slackened for removal or replacement. A bent, worn, or missing tensioning post that can no longer slide correctly or transfer the adjustment screw's movement to the guide bar requires replacement to restore accurate, reliable chain tension adjustment on the saw.
This tensioning post features a left-hand thread — an important distinction from similar tensioning posts in the Milwaukee lineup such as the 05-89-0017, which uses a right-hand thread for different compatible tools. Always confirm the correct part number from your tool's service parts diagram before ordering to ensure the correct thread direction. Using a genuine Milwaukee OEM chain tensioning post ensures the correct dimensions, thread direction, and fit within the tensioner assembly for the 2527-20 and 2727-20. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct tensioning post for your specific unit.
