D9R and 463 pull scraper

[dirtpusher9]

Rained out!!! WOOO HOOO!!!
It's been almost a year since I was able to do anything in the shop, that's entirely to long.
When I first built the dozer I put a winch on it and stripped the plastic gears in it pulling my riding lawn mower. I used a planetary and motor out of a cordless screwdriver and geared down some on top of that. I've been on the net trying to find some replacement gears and the only ones I found that would fit have been discontinued. So I need some suggestions on where to find some. In the first pic you can see they have a lot of wear on them. Trying not to have to redo the whole winch, so all the help you can give would be appreciated.



Here are a few specs.
pitch dia. .500
# of teeth 24
pitch 48
20 degree pressure angle
