Not very hard. I did Primary sheave, Secondary sheave gold spring, clutch slug kit all at the same time. Just watched the hunterworks video's a few times
One thing I didn't have was the spring tool for the secondary spring. It's a 45mm nut and didn't have a socket that would fit it also. Watched a vid of just standing on a tire to remove and replace it. So I used the left rear tire from the wolverine. Put the rim over it and stood on it.
For the Slug kit, not hard but may as well do the sheave while at it. Have to take the sheaves off to get to it. Hardest part was just removing all the old gasket material for the new clutch gasket. The front facing wire brush on the drill makes it ok but still a pain with the mess.
So for hardest parts, secondary spring, gasket removal, then putting the dang bed back on. Nothing that bad really.
