How to Replace the Bar Adjustment Kit on a Poulan Chainsaw (Model P3314)

How to replace the chain adjuster on a Poulan chainsaw The Facts

Chainsaw need a checkup? It's time to face the fix. Whether you are a legendary lumberjack or a weekend woodworker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.

The bar adjustment kit is part of the clutch cover assembly. It is made up of the adjustment screw, the adjustment pin, and a retainer. If you can't tension the guide bar, a quick inspection of the bar adjuster will usually reveal the problem. Look for a sheared-off adjustment pin, stripped threads on the adjustment screw, or a damaged screw retainer.

Sometimes, the problem will be broken or worn plastic where the adjustment kit attaches to the clutch cover. Most damage to the bar adjustment kit is caused by over-tightening the adjustment screw. This will quickly wear out the threads, or even shear the pin right off.

This article provides step-by-step instructions for removing and installing the bar adjustment kit on a Poulan chainsaw.
