Hi everyone, I have been lurking here for a while but need more specific help. I have a 1972 Gleaner K with a grain head which I use to harvest native prairie seed. My issue is a hydraulic leak coming from the variable reel speed driven sheave (figure 8 on page 17 of the manual). When I try to increase the speed of the reel, the "collar" that holds the sheave in place slides to the left and hydraulic fluid shoots out. The reel will turn very slowly without leaking but I lose a lot of seed if it's not turning fast enough. Is this as simple as replacing o rings in the sheave or does the "collar" need to be tightened down more? New bearings perhaps? Any help is greatly appreciated!
