Echo Chainsaw Transmissions and Clutches

Gear, Bevel This is a bevel gear, also referred to as a drive gear or tension gear, and is used in chainsaws. This authentically sourced part is sold individually. It is part of the chain tensioning assembly, aiding in loosening and tightening the chain on the chain bar. Once the chainsaw has be disassembled, the drive gear can be found on the underside of the clutch cover. You will need to remove the tension bracket screw, lift the adjustment assembly out, remove the bracket, and pull off the old bevel gear. Install the new bevel gear by sliding it onto the square end of the adjustment bolt, and reassemble.

Gear, Bevel This is a single bevel gear for a chainsaw. Your chainsaw has two bevel gears that allow you to adjust the chain tension. One has a post with a slot in it (for a screwdriver), which mates to a second bevel gear that is attached to the adjustment screw. This part includes the bevel gear that has the post and screwdriver slot, the other bevel gear mentioned is sold separately, so it is wise to inspect both at the same time and order accordingly. The bevel gear is prone to wear, especially if the chain is over-tensioned, however this is a basic repair that should not take very long to complete.
