I bought and moved a Powermatic 143 a few months ago. Removed table & trunnions & blade tilt screw. Put two 10’ 2x8’s against pickup bed and laid saw on its back and slid into truck. When it tipped into the bed, the 2x8’s slid in with it. Put 2x4 against top of gearbox cover and front of truck bed to keep it from sliding into the front of the bed and bending the tension screw. Plus lots of straps.
Unloaded the same way and gearbox cover had lots of oil in it and, when we stood the saw up, the oil got on the belts. There’s not a good way to stop the leaks. The oil fill is on the operator side and the vent is on the opposite side. You might tilt it to the operator’s left but there’s a flange sticking out of the base that would mess with your ability to slide it around and that’s the narrow side. I’d drain the gearbox next time.
30-100 non detergent was my best choice at NAPA. I drained the old oil (clean!) and refilled. I think there’s a level plug on the right facing the gearbox. Oil ran out after my estimated 1 1/2 pints.
The PO had changed to a 2 HP motor and a 3/8” step pulley. I changed back to a 2” pulley for a 1/2” belt.
Just for info, the PO said it wouldn’t go into low on the gearbox. I didn’t worry too much about that and figured it was fixable. I would have worried if it was locked up. At home I tried shifting while turning the belts and it changed. The belts were on high and the saw was screaming fast! I checked and someone had added a high-low tag turned upside down so it had been in low all along. Speeds are from 40 to 3000 rpm. Belts give a 4:1 change so the gearbox ratio from high to low is 18.75 to 1. High on belts and low on gearbox is about 140 rpm which is good for most metals. Just changing the gearbox to high gives 3000 fpm for wood.
