This is an epilogue to my previous post on discovering a worn arbor and loose fitting pulley when doing annual maintenance on my older (90-91) G1023 TS.

I went ahead and replaced the arbor and pulley, but I got the machined pulley that they sell in their catalog, not the cast pulley that is a replacement part (the original part was also cast, not machined).  I found the cast pulley bore was 0.005″ too large for a press fit on the arbor, and the older model (lacking the set screws to secure it) ended up with LOTS of vibration. The machined pulley fits perfectly on the arbor, and the arbor itself seems better quality to my old one.  For example, blades fit tighter on it.

At the same time I replaced the olded shielded bearings with ABEC-3 sealed ones, and the belts with twist link belts.

I unscrewed about every bolt and set screw on the machine, cleaned it, lubed it, and tuned it up (slot to blade, then trunions for 45 degree cut, then fence to slot).

Prior to this work, the TS vibrated like one of those motel beds you put a quarter in.  This vibration must have built steadily over time, as I just got used to it, instead of recognizing that a problem existed. 

Now the saw purrs like a kitten and is super smooth.  Cross cuts through oak look like they were polished with 4000 grit.

Moral of the story: know your saw and check its fitness often.  It’s worth 8 hours of down time!

One warning to others with older G1023s:  Grizzly does not always seem to  understand the differences with these saws versus the newer ones.  The motor cover sent to me was designed to fit on hinges that didn’t exist on the older saws.  Turns out the motor cover I wanted (and the one in their on-line manual) was also almost twice the price of the better quality new one!  Also, When ordering replacement bullet pins used in securing the handwheels, the ones I got did not fit and were a very different shape than the ones in my saw.  For both problems, Grizzly customer service has been quite helpful with either returning the part or looking for the correct one.

The bad side of doing the work is with the arbor change, I need new cross cut sleds and throat plates, as the saw blade is 1/4+” to the left of where it used to be!
