Sorry it took so long to reply, but I had to go take some pictures to post here.
You might be thinking of this already, but if it were me I'd try the chain first before turning down your pulley drum.
Taking these pictures jogged my memory a little, the first jib extension I built for this Cam-am did not have the diagonal piece welded in to form a triangle reinforcement.
My neighbor has finger/hand issues that does not allow for quick action to the winch toggle switch, therefore the first jib extension piece came back to me looking like a fishing pole does when it has a lunker of a fish on, and the 1/2" eye bolt was reshaped like a crescent moon.
So I fabricated a new jib with the gusset welded in, and straightened out the eye bolt.
This neighbor has since changed out his cable to a Cam-am approved winch rope and complained that his rope is fraying, and upon looking at the system again I have told him he needed a rescue type rope pulley ($10-20) for the rope (still has the Harbor Freight pulley that's too narrow for the rope).
From the start, I intended to fabricate a modification in such a way that he was able to see the cable from the drivers seat, and I told him to tag the cable (red material tied around the rope) so he'd see when the blade was raised to almost maximum height and not any further (with the new truss extension I believe his weak link is now his winch rope).
I know you'd fix your problem and glad to offer some information here.
B.T.W. I really like those tri-tracks you have.
