Last time I checked bushings etc. the hanger holes were barely holding the splined wet bolts. Next time I have things apart for an inspection I'm sure that I'll be at a point where the holes in my hangers will no longer hold the splined wet bolts from turning. Couple of thoughts..
1. I've already reversed the wet bolts so that the head is on the other side of the hanger. Thats a good temporary solution, but to be honest this whole idea of a fine spline to keep bolts (that are part of a regular maintenance plan) seems like a poor idea.
2. Replace hangers....I've thought about that and while its a solution, its temporary and at some point I could be back to writing this post all over again.
3. In one of the other rv forums, I read about a guy that took some 3/16" stock and cut it the same size as his hanger. He then machined a hex hole the same size as the wet bolt head. Once done, he slipped it over the wet bolt heat and attached the plate to the hanger with a small 1/4" bolt. This seems like such a great idea but cutting a hex hole in the 3/16" stock is a little beyond my capabilities. Anyone have any ideas on this for the common man?
4. On yet another forum, a guy welded some 1/4" key stock on the back of the hanger in such a way that it rested against a flat of the wet bolt hex head. Having a flat of the hex head against the key stock kept the bolt from turning. Again, a little beyond my abilities as I don't have a welder, but I guess I could tow my 2930 to a local shop and have them tack a couple pieces of key stock in place. If I did that, would it require removing the wet bolt and lowering the spring to prevent damage Never Fail bushings that I currently have?
5. One last thought....has anyone ever used tab washers (see photo below)? Putting a washer like this under the wet bolt head would allow one tab to be hammered against one of the hex flats the other tab screwed with a small machine screw into the hanger.
