I had posted some of this in the what is on your bench but decided to continue over here so that I could find it a lot easier later if needed.

I had diagnosed this with bad crank bearings especially on the PTO side.   I have all torn down now and when I got to the bearings I was correct on the bearings. 

Check out those transfer ports coming out of the crankcase.   Since I usually have torn down a lot of older saws I do not see this.  Cool stuff.

A few more pictures of the saw torn down.

I have all the parts I need on order from Jack's small engine.  I decided to replaced the crank because I could feel a very small amount of up and down movement in the big end bearing.
I am getting a new crank, bearings, small end rod bearing, all the gaskets, new crank seals, and new rings for 270.00 with shipping.   I am pretty satisfied with that and the saw should really do well when done. 

How about those removable crank stuffers.

What cc is it because that topend looks like that 576 topend.

The Husqvarna K960 cut-off saw is a powerful hand-held power cutter, featuring the revolutionary X-Torq® engine technology. It is a unique machine, in a class of its own when it comes to emission levels, efficiency and maneuverability. This model was replaced in 2011 by the K970, but we have a couple of K960 16-inch saws available - while they last!

    Cuts curbstones and pavers in landscaping.
    Pipe cutting in installation work.
    Asphalt cutting in roadwork and pre-cutting in pipe trenches.
    Metal cutting.

Benefits:

    The new Active Air Filtration™ is one of the most efficient air filtration systems on the market, delivering operational times (dry cutting) of about one year with no filter service required.
    Engine with X-Torq® produces more power, higher torque and 75% fewer emissions.
    SmartCarb™, a built-in automatic filter compensation, maintains high power and lowers fuel consumption.
    DuraStarter™, the dust-sealed starter, and the durable starter cord reduce the risk of downtime and increase reliability and service life.
    The Poly V-belt provides better power transmission, less retensioning and increased product life.
    Efficient vibration and sound dampening make the machine more convenient to use.
    DEX, dust-handling system, provides cleaner cutting with less water usage.

Thanks for posting that Kevin.   If you want to move the info over that would be ok.    When I get all the parts and get it put back together I will get some more pics.   The saw I think was really easy to work on.  It came apart real easy.
