## Product's reviews:
- Finding the right parts. - MRO made it quick and easy.
- 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.
- 80 tooth change gear - Exact part for the machine, deliverd quickly, and priced right!
- Fast shipping - I ordered this part hoping it would arrive within 2 weeks because I had an emergency situation with an employee waiting to repair a piece of equipment at a customer’s location. The part actually arrived halfway across the country in 5 days including the weekend. MRO processed, packaged and shipped it with incredible speed. Thanks again!
