Hello All,
I am planning some upgrades to my Craftsman contractor TS. I plan to replace the Zinc cast pulleys with new machined steel pulleys or balanced cast iron. Is there big difference in performance from either. I also am interested if there is an advantage to using a double belt pulley vs a single. Such as the set up of Twomartinis.

I can order the machined pulleys online $30-$40 shipped or buy locally the cast iron for $20 at a bearing shop.

Appreciate the input.

i have two emerson built TSs, one a ridgid 2412 with a ribbed OEM belt and the other a 113 series c-man (like that pictured) with two machined pulleys (one on each of the motor and arbor) with a link belt. the c-man is just a touch smoother than the ridgid, which i believe has it’s OEM CI pulleys. i’d go machined pulleys and single link belt. such a set up should provide outstanding service for you.

-- there's a solution to every just have to be willing to find it.

Oh Well I got it all figured out. I thought there might be some actual user experience with double pulley belts for a contractor saw.

The cast pulley can spread and the belt will or can slip. The belts grip on the sides and should never tough bottom of the groove. I don’t think you will need the second belt. Smoothness is related to trueness.

Another good option is the serpentine belt/pulley set for Ridgid saws that fits many of the older Craftsman contractor saws too….$28.50 shipped.

I replaced the cast pulleys on mine and it did make a difference. But I could actually see some wobble in the cast pulley on the arbor so they definitely needed replacing. The link belts helps a lot more, especially if the saw has been sitting a long time with the stock belt under tension..

By what I am seeing in the pic you posted it appears I have that same saw. Mine was purchased in the mid-60’s by my father. I recently swapped pulleys for machined pulleys and installed a link single belt. Made a huge difference. Miles smoother.

I then swapped the original 1hp motor for a new 1.5 hp. Again a huge step up.

Have your say...
