Motor turns --sprocket or chain doesn't


I'm assuming your kill switch is not engaged, the front handle should be pulled to the rear. It's normal to have some damage on the sprocket from loose chains catching on the corner so I doubt you need a new one. The motor turns? I'm assuming you're talking about the clutch, and if the clutch spins but the chain does not it sounds like your bar may be damaged or as you said the sprocket may need to be replaced if it's seriously been misused.

Garage door does not open or close


You have a stripped drive gear. Remove the cover from the motor unit and you will find white sawdust all over. The part number for the gear kit is 41A2817 and is available at any good door opener service company. It comes with instructions.

The motor on my Genie Chain Glide garage door operator runs but the chain does not run or move.


If the chain does not move but the motor runs then you have stripped the internal gears. I would replace here. These chain glide units are not very strong. There might be a chance the chain is telescoping down the rail but the trolley is not hooked up. Pull the red cord back toward the motor to engage. Thanks BB

The door only moves 15 inches in each direction. I just installed a new gear kit.


Loosen the chain enough so that you can remove the chain from the sprocket above the motor. Run the motor until the sprocket turns in the clockwise direction and stops. With the door in the closed position replace and tighten the spring. This will get everything in sync and you will most likely need to tweak the 'up and down limit' controls to get it just right.

NEED NEW CHAIN DRIVE UNIT INCLUDING PLASTIC


The model 028 Stihl Chainsaw was in production for many years and the clutch drum sprocket (or chain drive) came in three (3) versions over the years of production.
For several reasons, it is best to take the saw to an authorized Stihl Dealership (Locate your nearest dealership HERE) for production identification, evaluation of cost-effectivness and availability of parts.

Reason 1) The first-generation 028 saw is approaching 30 years old.

Reason 2) Extreme heat caused by a locked chain-brake can damage the engine case and render the saw unfixable (part support is going away due to age).

Reason 3) The shear cost of parts and amount of time it would take for a DIY repair.

Reason 4) The plastic gears you mentioned are the drive system that make the chain's oil pump work. If the plastic is melted, the oil pump is likely to be damaged as well. In most cases the oil pump cover gets damaged ... the list goes on and on.

Genuine Stihl parts are not sold online and aftermarket parts would be a gamble. It's up to you to decide if the cost, time and effort are worth it.
Hope this helps.

Craftman door opener brand new wont work?


Sounds like the drive gear is stripped. Remove the cover and take a look. It is white nylon and is just in front of the motor.

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

Lift master garage door opener. Motor makes noise when switch is hit likes its running but chain/sprocket doesn't move and the door is stuck open. Chain is on sprocket. Not sure if the motor is frozen? ...


I had the same problem. Took the cover off of the opener and found that the gears were stripped on the unit. Motor was fine. You can order gear replacement kit for the unit. They are a plastic type sprocket and worm gears. The kit comes with spindles and all necessary clips. You have to take the unit off the ceiling to replace the gears, but the process if very easy to do. Parts kit about $40 on line, much cheaper than a new door opener. Total process took less than 2 hours, including getting the unit down and back up again.
