## Product's reviews:
- Good seller - Catalogue item, good price, fast delivery = good seller
- Change gears - Found what I needed, fair price,...fast delivery....All Good!! Good job MRO Supply!
- Quality - very high quality. using these gears in a model 9 cylinder radial engine with a 1"
bore. about 8 h.p. , for oil pump a scavenge pump timing gears and distributor . very good quality gears.
- 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.
