Hi Simon,
I am sure we can find you a better gearbox here in Wellington. .
Another way to correct the wear on the thrust face is to machine the bush back and fit a needle roller thrust in it place- (They have a hardened washer each side)- not too difficult to do.
The pressure on this face due to the tooth angles is quite high. Combined with the grinding paste produced by the gears wear is accelerated.
One of the reasons straight cut gears give more power at the back wheels. the herringbone gears in a 4 speed crash box eliminates these forces to a large extent.
Give me a call if you want some help-027 779 7031.
Cheers Steve
