Screws and nuts that hold belt cover on

[earlmorton]

On my model 500 (and I assume the newer 510s and 520s), the belt cover is held on with two pan-head screws and two of those simple, stamped, clip-on nuts (sorry, I have no idea what they're really called). Has anyone found a better way? Those nuts get bent easily and don't hold well.

Thanks!

I replaced the screws and Tinnerman clips w/metric equivalent clips and screws from Tacoma Screw, on Central Avenue in Kent. The replacement clips were tighter and less likely to be knocked off into the motor pan. The difference did not make much difference, and the thinner clips were more difficult to put in place for the thicker belt cover holes positions.

Since then, I have shimmed the stock clips w/paper to hold the back pmotor pan clips in place. The screw has to penetrate the paper when the screw is reinstalled.


There are some automotive clips, with threaded receivers that may work, but they are for sheet metal applications and would be difficult to install on the casting at the belt cover holes.

Bill Mayo has a postingon replacements for headstock screws.

Hi Guys
Grasp the Tinnerman clips with a pair of pliers just forward of the rounded end and give a light squeeze. This should tighten them up a bit,

I have done these successfully many times but occassionally you may find a Tinnerman that has lost its ability to hold.

I went looking on the web and was not able to find what we are discussing under "Tinnerman". I need find "U" type speed nuts that I believe are the same things and will work.

I have not tried this, nor do I know if they are still available, but try threaded pop rivets with an internal tooth lock washer behind. Then a bolt will screw into the pop rivet threads.

This would probably work BUT to use pop rivets you have to drill a hole large enough for the rivet. Most of you will not be handicapped with my obsession with drilling holes in my Shopsmith so this will likely work. If anyone tries it, please let me know.

Here is a list of 135 diferent kinds of those nuts. Sometimes called J nuts and U nuts. They are even spec-d to various thickness of metals. http://www1.mscdirect.com/U,-J-&-Cage-N ... 06652.HTML

You should be able to find a clip or two at a local hardware. The neat thing about the clips is they use a screw rather than a bolt. Easier to replace a screw and not as exacting.

My Greenie uses type F thread cutting screws which self thread into the casting.

I finally got around to tinkering with this issue more, and started with this suggestion. (It was the easiest!) For now it seems to have worked great. I think I can live with this and replacing the clips with new ones occasionally when they lose their spring.

Thanks, everyone!
