## Product's reviews:
- Change gears - Found what I needed, fair price,...fast delivery....All Good!! Good job MRO Supply!
- Worm - Haven't used them yet, but they match the worm gear perfectly. They should serve the purpose for which I purchased them.
- Good seller - Catalogue item, good price, fast delivery = good seller
- 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.
