Replacing parts on Windmill

In my experience there is usually a hole all the way through for this kind of tapered pin and you can use a pin punch slightly smaller than the hole to tap the pin out from the opposite side.

I have tried punching it out- no luck. I have actually tried on a few presses, and I have had no luck. Its in there! I’ve read I might have to drill it out. We will see.

are you trying to remove it to replace it. Your machine keeps tripping cause that part is worn. I bent a 2 point brass rule over the part that rides on that, it will work for a long time. Dick G.

nice i will try that. i think it is worn because the spring on the opposite side has been shot for who knows how long! it actually crumbled out. ill see what i can do. thanks.

All tapered pins on windmills need a lot of force to get them out. Be sure to figure out which end is the narrower one to hit onto (if in doubt use a caliper to measure). Use lots of WD-40 for several days. Get the right punches and hit it.
DON’T EVER TRY TO DRILL THEM OUT! They’re hardened and all you’ll do is destroy is the surrounding parts.

thanks mob. ill start wd-40ing. i have the right punch for it.

Most pins on a Heidelberg must be removed from the end that is the most difficult to get to. I’m not being facetious, think about it: when they install the pin at the factory, the company makes the installation direction that favors the installer, not the poor mechanic that has to replace a part. Am I lying???
That pin comes out from the bottom. I have a set of pin punches with the tips cut to about 1/8”long. I get a fair sized ball peen hammer (not a claw hammer, those are for nails) and hold the punch with a pair of Vice Grips so I can keep my fingers attached to my hand after I swing the hammer. Get the punch as square to the pin as possible and be aggressive when you hit it. Usually takes multiple tries.
If the part is not under great stress, I often replace the taper pin with a roll pin after lining up and drilling out the part and the shaft in one shot with a drill slightly larger than the existing hole. Make sure that you size the roll pin before drilling.

Motto: If it breaks, it needed replacing any way.

Pin locates from above punch it out from below. If you cant get it out drill it and as suggested put a plain one in on re assembly. I have never bought a replacement for this part you just run a weld along the worn corner of the step and grind it back to a nice even finish but do take care as it is not as hard a part as you would think and the angle of the step is not quite 90 degrees.
