Topic tags/keywords: question tablesaw machined pulley

I have a Craftsman TS, model # 113.298030, that needs new motor & arbor pulleys. The manual shows the same pulley (5/8” bore X 2-1/2” OD) is used on both the motor & arbor. Jerry Cole at In-Line Industries said in an email; ”I’d order a “2358” pulley (2 1/4” OD) for the arbor, and a “2558” (2 1/2” OD) for the motor. They come with set screws, but not keys.”

I have a few questions for those in the know and/or have done this upgrade.

Q1) Does it sound reasonable to change the arbor pulley to the smaller 2-1/4”OD pulley?

Q2) Effects, Pros & Cons of changing the arbor pulley OD?

Q3) Is there a problem with the pulley NOT coming with keys?

Q4) Also the “2358” arbor pulley comes “Hub Type” & “Hubless”, which one is the right one?

Thanks in advance, for taking the time to help and for any & all input.

Randy – I think the advice is sound – your saw CAN tolerate a slight change…...go for it. And “Hub Type”......my vote.

reducing the pulley on the arbor will result in the blade speed increasing. the keys keep the pulleys from spinning freely on the arbor and motor. new pulleys don’t come with keys is OK since you have the keys on the arbor and motor shaft (shafts usually come with keys not the pulleys).

I have done it. Only I decided to go up to a 2 HP motor the original on that saw is 1 HP, I know they have a developed HP decal on the saw but it is a 1 HP motor if it is original. The problem I ran into is that a 2 HP motor shaft is 7/8” so I had to replace the pulley, the smallest pulley in 7/8” was just a little larger which was OK. Also the larger motor fit the original saw motor mount. I also replaced the belt with a link belt which smoothed it down a good bit. Good Luck, it’s not a difficult upgrade, I did mine about 6 years ago and have not had any problem. I don’t know if you have a latter model but mine did not have keys only set screws.

I have already purchased the PALS from In-Line and like their product. Since they deal with this all the time, I was leaning towards taking Jerry at his word, but wanted a second, third & fourth opinion. Plus, I know opinions are freely given here on LJs! Lol.
Sounds like I will pull the trigger tomorrow. I was curious regarding the lack of keys. I need one new key (available locally), but was wondering IF the In-Line pulley accepted a key or was only held by set screws? The upgrade is a no brainer, $8.24 for OEM cast pulley Vs $13.50 for the machined pulley (5.26×2 = $10.52 additional) for increased performance, & I already have the link belt. Duh…..
An upgraded motor is not in the cards (read; bank account), but perhaps in a few million years I’ll save up enough money.

Thanks guys!!!

The only thing left to do is reassemble & learn how to use this TS.

Q1 & Q2: Changing to a 2.25” pulley will make your blade spin faster.. for a 3450 RPM motor, it will make the blade spin at about 3833 RPM instead of 3450 with the 1:1 arrangement. I would probably just put back on what was there from the factory, but if you have a need for faster blade speed, it certainly shouldn’t hurt anything.

Q3: No.. they usually do not include the key. If you lost your originals, they can be had at any just about any hardware store off the shelf. Just make sure the pulley actually has a key way and not JUST a set screw.

Q4: Pretty sure you want the “Hub type”.. hub-less pulleys use a separate hub and can’t be used by themselves.

Cheers,
Brad

Randy – Jerry Coles has a lot of experience with these old Craftsman saws. He has a video out showing some of his tricks, and it features him using an old Emerson made Cman contractor saw. A few years ago, he demoed the then brand new Freud Fusion blade at a woodworking show using his old Cman contractor saw. I’ve spoken with him a couple of times at shows and on the phone. My impression was that he’s stand up old school guy, not a fast talking sales guy who’s full of hot air looking to make a quick buck. No doubt, I’d take Jerry’s word….it’s also not that much of a change in pulley size. You could always ask him what the benefits are….I’m sure he wouldn’t tell you to do it without a logical reason.

MrUnix,
Thanks for the info.
I realize the blade will spin faster & not by much, so I think it’ll be OK.
Do the pulleys have keyways or not? Keys or no keys, that is the question. I’ll find out when the pulleys arrive.
I believe Hub IS the way to go. Especially since closer inspection of the manual describes the OEM pulley as having a hub.

knotscott,
That was what I wanted to here. I do trust Jerry & In-Line, I was just hoping for some experienced input. Thanks for confirming. Know I WANT/NEED to know about the pros & cons of the pulley size change. Hmmm…..
