Gear Bevel Stripped

John from Hoosick Falls, New York

Tools:
Nutdriver, Screw drivers
Thoroughly cleaned the chain brake assembly of all dirt for the mere fact that the parts are small and need to be precision fit. Assembly was easy, laid out the parts did a dry run to make sure the parts were right, they were, and proceed to assemble the pieces. Used the chain saw on more than several occasions and everything is still lik e new.

Chain tensioner was damaged on Echo model 400 CS chain saw

Joe from Walls, Mississippi

3 of 3 people found this instruction helpful.
Difficulty Level:
Easy
Total Repair Time:
30 - 60 mins
Tools:
Pliers, Screw drivers
1. Removed clutch/sprocket cover
2. Removed chain and bar
3. Removed tensioner plate from clutch/sprocket cover using Phillips head screwdriver (2 screws)
4. Disassembled the 5 parts making up the tensioner assembly pulling out with pliers
5. Replaced with the 5 purchased replacement parts
6. Reassembled in r everse order
A relatively easy job. Just a little tricky pulling out assembly. Use pliers on the protruding portion that fits in chain bar and pull straight up. Upon reassembly, make sure the plastic/nylon collar is fully seated. An easy 30 buck fix. (Probably could have reused a couple of the old parts but had rather start brand new for the cost.)
