Clutch replacement

Recommended Posts

You should change the parts when they exhibit signs of wear such as deep indentations on the sprocket or rim, grooves around the inside of the drum or clutch shoes and wobble on the drum.

Failure to change a worn drum or needle bearing will eventually take out the crank and effectively writing off your saw....seen it a few times now.

Husky outboard clutches are not the easiest to remove but are made easier with using the correct wrench and I personally use rope in the bore on this model!

Any idea where I can get a spanner from to remove the clutch it very tight (562)?

I've only worked on much older Husqvarna saws and on those the nut is too shallow to use a spanner or socket so I modify a socket.

 

Are you undoing it the right way? it will be a left hand thread.

 

Note what Spud said, he uses a piece of rope ( I use starter cord) to jam the piston just before top dead centre. You do need to be careful and feed the cord into the spark plug hole after the piston has travelled up and closed the exhaust port and transfer ports else the rope will get stuck and damage the rings and possibly the piston not to mention being a pig to get the saw freed up.

Service tools are available, unlike what has been said i never insert anything into the cylinder, i have seen too many disasters even when care is taken, using this method is a direct force ontop of the piston, i always use the jarring method, just be careful when using the impact wrench.

I always use an impact wrench and have never had an issue. Removed some clutches that required a massive amount of torque which would be very difficult to undue locking the piston up.

An impact gun can shear the keys when used on some saws, MS150s are prone to this.

You will need the service tool as previously mentioned to use an impact gun.

Rope is OK as long as the piston covers the top of the exhaust port when inserted and does work OK.

Not having a hex boss on the clutch is a loss on these saws as it makes life a lot easier.
