Parts for Husqvarna 142: Shield / Cylinder Parts

This is a replacement screw for chainsaws. This screw attaches the cylinder shield to the main body of the chainsaw. Over time and with regular use, the screw can become loose or damaged. This causes the cylinder shield to become loose as well, which could lead to the entire chainsaw falling apart during use. A loose cylinder shield exposes the engine to the elements and can cause damage to the engine and the chainsaw's performance.Check the screw to see if it should be replaced by trying to move the cylinder shield. If it stays firm, then the screw is fine. If you feel any looseness or resistance, the screw will need to be replaced as soon as possible. Check the screws for wear and tear frequently.This is a genuine OEM part sourced from the manufacturer, and it is a size T-25 Torx screw. The screw can be installed with a screwdriver, and the installation process should not take too long. Remember to always be careful around a chainsaw's blade, even for this simple repair.
