Kuhn Machines use a lot of roll pins, usually double. By the time repairs are needed they are rusted and near impossible to drive out. Have a GA 7822 with a broke stub shaft on the rear rotor . Glad to see what the gear box looks like on the inside. Now I am considering welding the arm back to whats left of the stub shaft rather than attempting to replace the broken shaft.
I have the same rake with the same issue. You didn't show how you removed or loosened the top casting from the shaft. Any tips? Can it be heated? I got the roll pins out but the casting is not separating from the shaft. I am afraid to use a puller in case I break the casting. Any suggestions?
Good day good video picture is worth a thousand words. What did that gear cost.. PA farms was looking at one rake, talk to dealer about gear box, lif he had to buy one, they wanted $6900. for it. H laughed & said on video he could buy new rake, die fferent brand for 6400. Thanks for video
