Take off the cover of the motor unit and you will find the drive gear is stripped. It is white nylon and is just in front of the motor. A new drive gear kit comes with installation instructions.

WEN 6014: Motor is running, but chain doesn't move. Chain sprocket seems fine, cogs are only slightly worn, sprocket fits perfectly, no wear. Is there an internal clutch or connector? Motor worn out?


There is a clutch behind the metal housing where the chain sprocket at the engine end attaches to the chain . There are wear parts with springs on them that have to be changed. ChainSaw Shed Chain Saw Parts for Wen Wagner Brand Chain Saws Chains Bars... You can get parts here.

THE CHAIN SAW RUNS. THE CHAIN XS NEW. IT DOESN'T CUT THE SMALLEST OF BRANCHES


I don't mean to sound offensive, but is the chain on the right way? I've put 'em on backwards, even started the saw before I noticed. And is the chain running when the motor runs?

If the chain is right then you may have gotten a chain with a bad grind. Never heard of it but it could sure happen. Get back with me if the chain is right and it's turning- we'll get it to cut.

Chain jammed on plant won't run after pulling most of plant from inner part of chain. Makes humming noise


The humming is the motor trying to turn. Remove the drive end cover from the bar and chain--back off the chain adjustment CCW several turns. If the saw has a chain brake, release it. When the cover is loose, remove the bar and chain, inspect the entire mechanism for any damage--particularly the chain itself. Run the motor without the bar and chain, and check for oil oozing out of the side port in the motor case where the bar fits. To reassemble, fit the bar in place after cleaning the small oil passages in the drive end, then fit chain over the sprocket. Pull the bar outwards to tighten the chain, then fit the cover and fasteners finger tight. Adjust the lower run of chain up to the bar (the lower run of teeth cut toward you), but not so tight that you can turn the chain by hand. Tighten the fasteners and recheck chain tension. Chain saws don't seem to like cutting hedges and other small branch, but tough bushes and the like. Make sure the chain teeth are properly sharpened. Hope this helps!

Electric Poulan Pro 400E won't run. Can't turn chain manually or turn chain sprocket either. Feels stuck and won't budge.


Loosen the chain as it could have run over something or tightened itself as the chain dried out. But if it won't turn and it just humms or does' nothing the motor may have overheated and locked up. The motor may smell burnt ( like a hot elecrric stove) and it may be melted together. If its halfway new and you have the reciept you can try to exchange it but certain kinds of failures may not let you get an exchange

Garage door opener (chain) motor runs in reverse. Trolley slides forward trying to close door, even though it is closed, instead of sliding toward motor to open door. Happened out of the blue - was


Loosen the chain enough that you can remove it from the sprocket. Run the opener until the sprocket turns counterclockwise and stops. With the door in the open position replace the chain. You will probably need to adjust your open and close limits per your owners manual.

Garage door opener motor runs, but the chain drive doesnt turn


If the chain is not moving and the motor is – you need a gear kit.

Unplug the unit - take of the cover – you will find white shavings inside – these confirm the diagnosis. .

Get the gear AND sprocket kit.

It’s a good DIY project but you MUST VERY CAREFULLY Follow the instructions step by step.

HOPE THIS HELPS

Motor runs but gear doesn't turn on my Craftsman 1/2 HP


What did you pay for near gears. curious. often get stripped gears in cold weather as door is frozen down to ground. if possible, kick door bottom edge with heel to break bound if you suspect it is frozen to ground.
