Governor rockshaft extension bracket repair.

Thu Dec 20, 2012 11:43 am

Not wanting to go through and re-invent the wheel if someone already has a good method/practice for repairing/restoring this bracket. I had read through quite a bit in past posts about rebuilding the governor, but I was not able to find any mention of repairing the actual bracket. To make sure that we are on the same page, it is listed as #5 in the parts manual picture (251469R1).

I have an idea on repairing this bracket to remove the slop/wear that is present, but before I get into it, I thought I would check and see if anyone has come up with a way to do this repair or an alternate method. I have seen a lot of tips and ideas to remove as much slop/play from all of the different connections and wear points, but I have not found any mention of this point. Any help or ideas would be appreciated.

Check for wear in the woodruff key, part #6. Usual location for a lot of the slop.

As an alternative to replacing the parts, I have personally used JB Weld to secure the joint.

Wrong end of the extension shaft. You guys are talking about this part:

Just trying to see if anyone has a method of taking the slop/wear out of this point before I start on my idea.

Drill it out and press in a bushing.

Since that is a casting, welding on it should not be done except if absolutely necessary-- if it was broken, for example. The piece that fits into the worn hole could be welded up and made oversize for a tight fit. Or a bushing could be pressed into the hole and then drilled to the desired size.

That is the route that I was starting down. Like I had said, I didn't want to try and re-invent the wheel. Just a little bit of set-up to get it done right, then press in an Oilite bushing, and also add on oil hole to the top of the bracket. I would have thought that there would have been a bushing originally at this point, but I guess not.

The cub was only designed to last a few years not 50 or more :D it was built on the cheap side back then.
That is one part that have have had few problems with to tell you the troth I can not remember having to replace one on account of excessive play in it.

I have had more of an issue with the connection there between the shaft and the coupler that attaches the flat lever to it. It develops slop in the roll pin/hole.

Nothing spectacular or complicated, I know. I just made a quick little fixture to hold the bracket to an angle plate, then centered up with the existing hole, nearly 0.050" oversize (and oblong). Once drilled out (31/64") and reamed to 0.500" I pressed in an Oilite bushing (AA-521-1).

The only thing left to do now is drill a hole at the top of the bracket for a small press-in flip-top oiler. After that, ream the bushing to size, and it's ready to go. That should keep this point well lubricated from now on.
