Table spring hanger

[70/70]

I have to replace some of these (the pin on machine frame). I have never had to do one yet. Any tips/advice before I get started would be greatly appreciated.

You mean the pin that the counter balance spring attaches to?

correct

From what I remember you just cut them off flush with the frame and then pound out the stud, insert the field kit and your ready to rock. It has been a long time since I put one in and even then I was only a pinchasser being taught by the head mechanic. Haven't needed to do one since.

The way I've been doing it.....

-remove catwalk

-the sweep has to be down so the links are not in the way but if it is then the rocker arm is then in the way so with sweep at guard disconnect the long rods from the sweep links then crank the sweep to zero. What this does it gets the sweep links and rocker arm completely out of your way- (otherwise the sweep links and rocker arm make it impossible to get a grinder in there)

-with an angle grinder grind off the weld on the pin flush with the frame

-with a punch, punch the broken pin out of the frame

-now with a nice clean hole there, install the replacement pin, hook the spring on, put the catwalk back on, crank the sweep back down and re connect the rods..... done

Easy-peasy.

I second what TableJam said. How did you know that is exactly how I swap them?.....Its a little weird that you even know the order I do it in...

I like challenges.

My recommendation is as follows, as I think it's probably not the greatest idea to bang up on the broken pin as damage to the tube may result, causing considerably more repair time.

Grind the old pin flush only if it will get in the way (no need to have unnecessary sparks in the pinspotter). Drill a hole away from the original hole, but be aware of where the mounting bolt for the sweep frame is. Don't overtighten the hardware if the new hole is as pictured, otherwise the frame may collapse.

Honestly I think I'd rather have sparks then worry about over tightening and the frame collapsing...

Trying to fit a drill in there is not fun.

I drill a new hole

1. Must be lower or you have sweep rocker clearance issues'
2. A right angle drill makes it a snap to drill a new hole
3. Removing the catwalks sucks

3. Removing the catwalks sucks

Yes it does!

Can you get an angle drill in there w/o removing catwalk?
