Can the top wheel exhibit any free play when the saw is tuned
correctly?

What's "wobble" ? Is this a movement under force, with the tension
spring pulling it back to one side ? That's normal.

Is it smaller, but not under spring tension ? That's time to look
at
the top bearing.



Andy, thanks for checking to see what the problem actually may be. I
may not have described the "perceived problem" with enough precision.

There is not any wobble when running. As I mentioned, the blade
tracks very true, right in the center of the tires. The movement I
see is when I physically force the wheel side-to-side, when shutdown,
as if to check for play. (That's the normal mode I'd use on a vehicle
wheel - it's sort of ingrained.) The wheel moves right back when I
release. I suppose this is from the blade tension? If it's not
tensioned, it's much easier to move it side to side. No top-to-bottom
free play movement is noticed; I think this is because the tracking
adjustment screw is locked down securely?

I don't think this is a bearing problem, the saw hasn't seen that much
run time. I'm just trying to ascertain if it needs any tweaking, for
optimum performance.

Thanks again,
John Sellers
