## Product's reviews:
- 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!
- 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.
- 12d.p. 14t spur gear - This item was closer to exactly what I needed than I had thought possible to find in the last 75 or so years. quite affordable, too. I almost didn't look, but when I did, there it was. I had in hand in just a couple of days.
- Boston gear order - MRO had the items that I needed. I ordered them and they were shipped faster than I expected. It was a pleasant experience all around.
