This 750 gear has the correct ID bush if any use .

sorry for the delay in replying

i measured the diameter of the bush and its about 0.20 over size, the shaft is around 0.15  down.

there is also a lot of sideways play on the gear, i can get a 30 thou feeler guage between the gear and the 20 mm spacer and this removes a lot of the wobble in the gear. i may have to get or manufacture some new spacers.

i did some investigating into the bush itself and they look very similar to a wrapped bush

if you look at ashimoto's pic you can just see the line where the bearing is split at the top right,

steve at 400 four bits has got a gear in stock so im going to e-mail him  and see what he wants for it and i will also find out a bit more info on the bushes themselves

No worries Just pay the postage & send me your address. I have a 13.7 mm and a 16.7 mm deep one . Which one is best for 400?

OD is just under 27 mm ?  Since I have pressed out don't worry about postage just put the cost of a stamp in your local charity box.
