I recently replaced the 5-HP motor on my Grizzly right-tilt table saw. (To be honest, my husband did because this weakling couldn’t lift 65 pounds.) I figured it was a good idea to replace the belts, too, so I ordered a set from Grizzly along with the motor. I’ve now gotten 3 sets of belts from Grizzly and none of them match my old, original belts.
My original belts were FM-26. The first belts sent were 3V-250 which were the same configuration but too short. When I called back, I was sent 3L-270 which were not as deep and were longer but fit on the pulley and could be tensioned adequately. I called to ask if they could be used successfully even though longer and not as deep, and they sent 3L-260 which is again the same configuration.
The 3L-260 and 3L-270 are not matched sets, but the 3L-270 are Gates belts. The 3L-260 belts are Bestorq brand (they seem to be pretty poor quality) and are very warped (don’t set flat when on a flat surface).
1. The salesman in our nearest woodworking store said whenever multiple belts are run on the same pulley, they must be matched. I was told by a salesman for Gates belts that all their (same size) belts are matched even though sold individually. How important is this?
2. Grizzly seemed to think that the depth of the v-configuration wouldn’t make a difference, but none of the technical support staff with whom I spoke sounded certain. Will these belts wear more quickly or cause additional wear and tear on the pulley or motor? A Gates distributor in the area did not have the belts I need (which I believe to be 3V-265) and would not sell me the 26” belts they carried with a slightly different v-configuration because he said they might not set properly on the pulley. The angle of the 3L is the same as the 3V, just not as deep. I’m concerned about dishing after a period of time.
3. If the depth of the v-configuration doesn’t make a difference, would it be better to use the three Gates 27” belts and adjust the motor accordingly, or attempt the 26” (Chinese quality) which will be much harder to install since even the old belts which are ¼” longer were not easy to install and remove?
This frustration has left me without a tablesaw for weeks now and I’m having withdrawals, along with my frustration. Can any of you genius, mechanical-minded LJs help? Thanks in advance.
