Husqvarna chainsaw

[mthieme]

Hopefully someone out there can steer me in the right direction.
I need to replace the spur gear - the gear that drives the chain. It appears like it is pressed on. If a puller is required to get it off, it's probably a special tool as it would have to be relatively small. I might be able to get a bearing separator under it and pull it - dunno. Don't wanna damage anything though.

Re: Husqvarna chainsaw

Isn't that gear integrated into the clutch?

The main nut is probably a reverse thread and you need a wheel puller.

Pull the plug......and with some rope feed it in the sp hole .....leave some outside then turn till the piston stops hit gear with a punch.....reverse thread eh

Re: Husqvarna chainsaw

It should be threaded directly to the crank shaft. What we used to do was give the internals of the clutch a good rap with a hammer and this will cause it to spin free.

That gear is actually attached to the outside of the clutch and should be replaced as one unit with new weights and clutch pads. So don't worry about messing up the weights.

This will be a LEFT handed thread. so when your looking at the side of the clutch you'll want to hit the right side down, to cause the clutch to loosen off the shaft.

Let me know if this helps.

Yup! And depending on the age of saw, older ones had a nut on them the same size as your spark plug wrench. newer ones have a spot on them that you can set a punch in and give it a whack. Some you could use a large washer and make a tool weld legs on one side to fit between the pad supports and a bolt on the other to stick in a impact wrench then buss it off. when replacing clutch , you can buy one with a permenent sprocket , or one with a replaceable sprocket. On most you have a choice. also while it is off check the oiler gear. They are plastic and will wear if chain gets stuck and clutch gets over heated.
