Technical Help to properly remove these..

1953 Chevy 150 Sedan windshield wiper motor trim clamp thingamajig. thank you.

 

Best way is to make a tool. Get a piece of pipe the same size as the retaining nut (the circle with slots) grind or saw through from 2 sides leaving tabs to fit the slots. Nice clean cuts and snug fit will do it. You will have the tool to reinstall and not mess up the nut.

 

I have used a very small screwdriver and a hammer and "gently" tap in one of the slots to unscrew. Worked for me.

 

thank you. I believe I have a tool I can use for it now. cheers!

 

Used a bicycle spanner with dimples on it to get a friends out.

 

for sure. I did that, it works great.

 

The proper name for the thiggamujigg is a " BURR " or so G.M. named it in the Service Manual

 

The tool is called a windshield wiper escutcheon bezel nut wrench. You can buy one, but as others have said, it's pretty easy to make one out of a piece of tubing.

They look like this:

 

thanks

 

I make them out of the right diameter socket wrench, on a grinder.

 

I've used a set of needle nose pliers just have to be careful.

 

90° ring nose pliers may work, also.

 

Same here, I have also use a set of small 45* needle nose pliers.
