    I would have purchased 2 of these and reworked the mounting bracket.

    Why reinvent the wheel, when simply making a stronger more robust part. Will, drop in and meet the existing engineering requirement.


    Using pillow bearings, would require more than drilling a few holes in the deck. First problem to solve, the chain drive side not shown. The diameter is aprox 4 inches, a pillow bearing having the same ID used for the belt & chain drives. Will require a riser to be built in order to gain the proper clearances.

    Second problem to be addressed: the alignment of the two shafts. The one we are talking about and the one that drives the wheels.

    What I'm making is a much easier way to rectify the broken casting. It has taken a few hours of machining, and confident when the paint drys, it drops in place and off to the races.

    just saying

    Re: Yazoo jack shaft failure/repair

    I guess I should have said with the tools that I have I would have done it this way. All I would need is a plate of appropriate thickness and size to raise the platform to the correct height and attach the pillow bearings. You can also place the pillow bearings as far apart as you want so less stress would be put on the support. I would have made it support the outsides of the shaft and left the center unsupported. That wouls be a much stronger setup.

    With that said I was looking at your pictures and it looks like you created your hole with the grain that looks to me would be the weak point and allow it to fail again. I have circled some of the grain marks that I think will give you problems. Way more grain marks than I can mark.

    A couple of questions:

    What keeps the shaft from moving horizontally?

    Did you provide for lubrication, such as a grease zerk?

    Thanks!
