Planning to replace drive belts on the saw (jerky start up) and want
to make sure I get the right size and enough length. The existing
belts (off brand automobile v-belts (original?)) are 1/2" on the wide
side. My imprecise estimate is that they're each about 24" in total
length.
So is 1/2" link belt and buying 8' (3 belts plus the "more is better"
principle) about right?
Thanks.
Tom

Barry:
thanks for the input. The saw is not "new" as I bought it used, but
not VERY used. The prior owner had it in one of those public storage
sheds for about 1 yaer before getting tired of paying the fees, so it
sat unused in Texas heat for some time. I suspect the belts toook a
pretty god "set". They look great, no visible wear. I've run five or
six hours on it in the last couple of weeks. The first start up of the
day is pretty abrupt, then subsequent starts are smoother as the belts
warm up.
I don't mind the expense of sticking link belts on it, just not sure
of sizing.
Regards.
Sorry Tom,
I still have the belt from Jet Contractor saw that I had as well. It says
the same thing. I installed a link belt on it. My guess is the 250 means
is 25". It was an 1/2" belt, size A.

WW Grainger has a good overview of different sizes of v belts and a =

Read the label on your existing belt. It should say something like A-52, or
A-50. A if for 1/2" and 50 is for 50".

Thanks Darrell. I appreciate your response. Regrettably the only
markings on the existing belts are
"First Auto Belt", "17-250" then a "20915". probably a part number.
Probably Taiwan markings. I had hoped that someone with a Jet knew
the right size.

I would be tempted to "rotate" the belts. Take off the tension, rotate
one belt a third, rotate the second belt a third the other direction,
leave the last belt alone, retension. I think this would cancel out
any "set". I also think that a bit of Googling in this group would
suggest that abrupt startups are more or less normal anyway.

Thanks. I was more concerned about getting the correct width but
concensus now seems to be it's a 1/2" belt. Length is easy as you say,
just overbuy!

If it's new, wait.
Cabinet saws are heavy, they dampen a lot of vibration. Belts soften
and stretch with use.
If it's not new, go for the link belts.
