I have an 1986 YFM80 that I bought for my son the thing is I'm trying to replace some of the worn parts so I started with the rear axle . There are 2 spaner nuts that hold the brake drum on I got one it was tuff to . Now the other one will not come off has anyone have this trouble or know how to?

 

I warm them with a welding torch, the inside one is a problem as heat can destroy the seals behind the nut, but it is often the only way to go.

 

Thanks I do know that had to use a cut off wheel to get the first one off will try the heat tomorrow been using a lot of wd40.
