Cover Pool Shear Pin Hole Missing...

Brand: Cover Pools
Part #: 050239

I could use some help figuring out what happened to the shear pin hole within the pool cover shaft. This is my third season as a pool owner and the automatic pool cover has been the biggest challenge of managing the pool. The shear pin seems to always break. After watching our pool cover person knock it out and replace it 4-6 times the first couple seasons I've since learned how to do it myself. My current challenge is that the hole within the shaft doesn't seem to be lining up like it normally does. I'm unable to see the hole to knock it out with a screw driver. I've gently turned the shaft 360 but do not see it as the shaft turns Any thoughts, ideas or recommendations?

Some additional context. I've had the following maintenance on the unit over the first 2 years:

• Year 1:
  • Replaced the rotting cover that wasn't being cleaned and maintained each year.
• Year 2 (last year):
  • Had a new concrete pit and drains poured to ensure the motor and shaft was sitting level.
  • Motor, shaft and pulley tune up. Everything was stripped, greased, serviced and put back together

You just have to turn it on/off, forward/back to get the hole in the main shaft to line up so you can put the shear pin in. I bought a box of a hundred and still have about half after 19 years. On mine it sits on top of the concrete which adds a whole lot of tension. Like dragging a wet towel so broken pins often.

I think I may need to drill out the broken shear pin. It won’t come out with a punch and hammer. Has that ever happened?

what type and size pins is your 100 pack?

1/4" x 2" I can't find the box I bought but I use the black ones. Just search on amazon for roll or tension pin.
Yes it's tight but I learned NOT to use the 1/4 punch because it will not come out once it goes through the hole. I just pound a new pin on top of the old one and it always pushes it though while seating itself.

Sorry duplicate message

thank you @avspin . After wrestling to get the broken bolt out, I was able to get it going again. This time with a tension pin instead of a bolt which is what had been there every other time I had hired someone to fix it. I hope the tension pins are easier to manage moving forward. Ill try your method of knocking out the broken one with a new one.

Hey Steve is it possible to take a large channel lock pliers and manually turn that shaft til your holes realign?
