Today I was helping a friend put his snowblower on for the winter. I noticed that the shear bolts had lock washers under the heads, so I decided to investigate further. They wouldn't come out without a lot of persuasion from a hammer. Upon removal, I realized what the problem was. Apparently, when he broke a shear bolt he put the lock washer in the wrong place i.e. under the head of the shear bolt which changed the alignment of the grooves in relation to the shaft. It is obvious that he probably would have broken these also if it were not for his mistake.
What I can't figure out is why the bolt that holds the female clutch shaft, which has a keyway is broken. I found it broken last year also and replaced it with the correct bolt. I took it off to check to see if the key was still in place, and it is. This has me baffled. It is broken just like a shear bolt.
