I have a multi system sharp vcr, and recently it refused to eject the
tape.
I found out the gear at the motor drive shaft that is responisble for
loading and ejecting the tape is crack.
However, i am unable to find replacement gear.

The gear is a bit small, and using the krazy glue still can't make a
tight gear.

Don't use crazy glue or you'll have to remove it to make a quality
repair. Glue simiply doesn't work well enough on nylon, which is best
repaired by melting it back together with a soldering iron and some
scrap nylon of the same type (another nylon gear, not a nylon wire
tie). As with metal welding, melt the material almost all the way
through. If the center hub of the gear is cracked, melt it back
together and place a metal sleeve (thinwall tubing - brass, steel, or
aluminum from a hobby or hardware store) over it, using epoxy to hold
it if the fit isn't snug.
