Husqvarna 350 - Clutch Removal / Replacement

01/22/2009 7:32 PM

How do I know if the clutch on a Husqvarna 350 is worn-out? And how do I remove the original clutch?

If you've done enough cutting to wear out the clutch, then you should notice the difference.

To remove/replace it is simple enough (usually each 2 chains that are "sharpened down.) and the clutch "drum" is also the new sprocket. Usually it's the sprocket that wears out due to the stretch in the chain causing different effective pitch.

Engine stopped (obviously), take off the side cover, remove bar and chain (move chain adjuster to "fully retracted" position ready to fit new chain.)

You will see the two "C" shaped springs and counterweights inside the drum. You will see the end of the crankshaft. In the casting will be two ramped depressions (opposite each other) that form a notch for LEFT HANDED removal of the casting from the shaft.

By hand, move the shaft till you feel resistance of compression, put a flat ended tool angled into one notch and give the tool a sharp tap with a hammer in the "untighten" direction.

Repeat this alternating between the notch that you use until the piece comes free, then simply undo it. (DO NOT try to remove any of the springs or dismantle the flywheel/spring/casting assembly. I think it would be very tricky to re-assemble.)

The clutch/sprocket will then simply lift directly off the shaft. Clean the shaft, fit a new replacement including needle bearing kit, screw on the spring assembly as tight as you reasonably can without hand tools (that's what I do anyway and I'm up to 15 chains used in the 10 years I've had my Husky 350 saw.) Best birthday present ever from a father in law.

Fit a NEW chain at the same time, like pushbikes, don't fit old chains onto new sprockets.

If you need further direction, send me a note, I've got a spare clutch/sprocket in the shed and should be able to find part numbers and such for you.

It'd be better to describe your symptoms than ask for clarification by others of your guesswork. Your Hooskie saw class has been discussed and illustrated extensively/intensively on this site. Before removing sprocket or drum...best to determine if replacement is actually needed. These are not parts typically requiring replacement.

UH, first tell us if you are talking about a Husky chain saw or a Husky bike! The instructions are a bit different...

Please, what Husqvarna 350 "bicycle" might you be referring to? Or "Husky" bike at all, for that matter?

Huffy refers to former Huffman Bicycle Mfr Co.; Husky (Huskey) refers to a tool line(but not chain saw) branding; Hooskie (not offficial) refers to properly enunciated pronunciation of the mfr name, Husqvarna (: hoosk-va-´airna...not husk-´var-na...not hus- kwe-´var-na).
