Swapped out the stock motor pulley for this SC4 timing pulley and the fit was spot-on for my bench lathe. The machining on the bore is clean and it seated without any wobble, which made belt tracking noticeably smoother. Took maybe ten minutes to swap and I'm back to making chips.

Finally got the timing right on my lathe after swapping in this SC4 motor pulley—the fit was precise and the machining felt solid. My cuts are cleaner and I didn't have to wrestle with alignment. Just what my bench setup needed.

Had no trouble fitting this to my SC4 lathe, and the teeth mesh perfectly with the belt. The only reason I'm not giving five stars is that the set screw hole needed a quick deburring.
