I have the original vacuum wiper set up on my '52 power wagon. I had the vacuum motors rebuild by Fickin wiper service and they work great. The problem I am having is that as the wipers work after a bit the arm gets loose on the wiper motor stud, then the arm will rotate too much and flip back over the cab. The little acorn nut at the end of the stud is tightened down well, but it looks like it does not push down hard enough on the wiper arm base. I am wondering if I need a washer under the end acorn nut so as to squeese down on the arm better, and thus prevent loosening. The schematic does not show such a washer but that is what I am thinking. I am traveling now so can't post a picture, but can later if necessary.

Doesn't the shaft present something comparable to a tapered spline that engages with the hole in the arm? What is the condition of those features?Power Wagon Advertiser monthly magazine, editor & publisher.

The hole in the arm was slightly smaller than ideal; could not get it to go on the shaft. The wiper arms had come with the truck but were unattached- I think they were aftermarket.
I did a little research and Dave Butler had commented at one point to carefully drill out the arm just a bit to allow the arm to slip over the shaft. I did this. The issue seems to now be that there is some movement allowable of the arm that occurs along the shaft length. This seems to be preventing the little nut at the end to fasten it down tightly. Perrhaps I drilled it out a bit too much. Maybe I should build up the shaft at its base with JB weld or something?Comment

If the motor's output shaft looks to be in original condition I don't think I would modify the shaft. I don't mean to be disrespectful of your wiper arms, but I would replace them before I would modify the shafts. Plus, application of a substance like that can easily be at best a short term solution.Originally posted by Doc Dave View Post
Does the Ficken organization have any arms? ....or arm repair parts? It is interesting to note those people are still in business. I remember them from decades ago when I first learned of them in Hemmings Motor News.Power Wagon Advertiser monthly magazine, editor & publisher.

Fickin Wiper SVS
I think they are the only one's left? I think Gordon is right, I would not mess w/ the shaft, get a new pair of blades & go from there.Comment

I may ask Ficken about wiper arms, they are still in business.
The arms i have now are probably from VPW but not sure.Comment
