dat521gatherer Posted January 21, 2011 Report Share Posted January 21, 2011 I find that most 521's have a really loose blinker switch. Maybe this happens to other models too, i dont know. Here's how I fix it. Take off the column and locate the roll pin that holds the shaft part of the switch Tap the roll pin out use some wd-40 on it. Pull it out to reinsert through the top on reassembly. Carefull not to loose the ball bearing and spring it will be gunked on there with 40 year old grease. Clean it up. Also clean up the copper plate thats for the bright light switch. The ball bearing and spring are for the bright lights too. This gap with the red arrow is the problem. I'd say around 90 percent of the looseness. It needs to be filled in with something. I use loctite. on my 72 on my 71 Now if you dont have a vintage hires root beer bottle from the 50's this ain't gonna work. :geek: The only problem with the loctite is it takes around 2 weeks to harden. I suppose you can use epoxy or jb weld but you'll have to work it into the gap. The loctite is so runny it flows right in the gap that]s why I use it. On reassembly put a dab of new grease to hold the ball bearing in place. hold the blinker arm into place and tap the roll pin back in from the top. 1 Quote Link to comment

datzenmike Posted January 22, 2011 Report Share Posted January 22, 2011 Good write up and oics, but you sure that thread locker will set hard enough? It's not really made for filling holes. Do let us know how it works out. Quote Link to comment

It's not really made for filling holes. Do let us know how it works out. I did my other 521 a couple years ago and its still rock steady. It reminds me of polyurethane which I suppose would work well too. I spilled a little polyurethane in the bed of one of my trucks and Its there for life. Harder than a rock. I'm surprised people dont use it to seal rust like por15. Quote Link to comment

nkldime70 Posted March 18, 2011 Report Share Posted March 18, 2011 what did you use to clean both the copper contact and the shift rod itself? Just curious. Thanks Quote Link to comment
