## Product's reviews:
- Shaft output is reversible - Description should say that shaft is reversible. Other than that perfect fit. Good communication from the shipping folks.
- 80 tooth change gear - Exact part for the machine, deliverd quickly, and priced right!
- Gear box oil - This has been very hard to find. It’s the oil spec’ed for my 1950s Rockwell wedge bed planer gear box. I haven’t found it anyplace else.
- Excellent customer service - The couplings are just what they are supposed to be. But I wanted to comment on MRO. This was my first order with them and I was extremely surprised at how well the company is run. I will be doing more business with them in the future.
