Milwaukee Chain Tensioning Post
Model Number: 05-89-0017
The Milwaukee 05-89-0017 is a genuine OEM Chain Tensioning Post for compatible Milwaukee chainsaw and pole saw attachments including the 49-16-2720 Pole Saw Attachment and the M18 FUEL QUIK-LOK Power Head (2825-20) system. 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. The post works in conjunction with the chain tensioner main screw and adjustment screw to provide the complete tensioning mechanism. 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.
Using a genuine Milwaukee OEM chain tensioning post ensures the correct dimensions, material, and fit within the tensioner assembly for the compatible attachment it serves. Non-OEM posts may not match the original dimensional specification or slide correctly within the tensioner housing, leading to inconsistent chain tension adjustment. 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.
