I'm always looking to save on repairs. When I do have to buy spares (sadly frequent on my bashers) then I check at least three sites on price and make sure that includes post costs.
I had a little triumph today with the 500.. tail output shaft was bent in the last encounter when a tail grip bolt sheared. I had kept the last replacement output shaft where I'd stripped the gear so i had a good gear and a good shaft. It turns out that the gear is pressed on to a splined portion of the shaft and proved possible to swap the good one over to the good shaft. Reassembled it's all smooth. Looking closely at the front tt the black gear will also be pressed onto a spline. The white gear I'v tried to remove before.. has a little pin through it but so far my one go at filing it off and tapping through was dismal: won't stop me trying again.
I also managed to restraighten the torque tube itself today. I haven't measured yet but reckon there's a good chance the tt diameter is the same as the skids. If so then broken tt's can be recycled by making up a mini pipe bender.
