AW-1, MD-2, MD-3 and MD-100

nylon gear replacement services

Most of the nylon gears in the AW-1, MD-2 & MD-100 rewind and MD-3 wind are split due to old age, see below, and original Nikon parts are now very scarce. I am now down to my last four new Nikon MD-3 gears, and previously I limited the re-gearing service to a few customers with mint MDs. However, I have commissioned a specialised gear company to manufacture the AW-1, MD-2 & MD-100 and MD-3 gears in brass for me. These brass gears are superior to the original nylon ones, as they are much stronger and will never split. Hence I can give a life time warranty on the replacement brass gear against any defects. Also, the re-geared MDs are actually quieter than when they were new, because of better gear couplings.

The re-gearing prices are :
