I'm needing to make a new thrust washer for the rotor drive sprocket on an old Howard 300 rotovator, but I'm not sure what material it's made of.
Initially I thought it looked like copper, but after having to heat the bearing sleeve next to it, it now looks a more bronze colour. Photo -
I only need one, as the other side has negligible wear.
Also, any suggestions for where to get suitable material?
thanks moray
