## Product's reviews:
- Electric motor pulley sheave - Good selection of motor belt pulley sheaves. Found the size unit I was looking to fit to my new compressor motor. confirmed with manufacturers rep then ordered. Price was good and MRO ships out ASAP. Free shipping. If you need real soon have to pay for quicker shipping.
- Has the parts - Its hard to find parts these days. When I reorder, they are in stock and shipped quickly.
- 21 tooth 12 dp spur gear - The 21 tooth 12 DP gear I bought arrived very quickly.
It was exactly what I needed to fix my RV slide out.
I had to machine it to fit, but I knew that when I ordered it.
VERY SATISFIED!!!
