Over Running Coupler Removal

[8N457568Guy]

'52 side mount 6 volt positive ground.

I want to remove the PTO Over Running Coupler so that I can install a PTO cover. That thing scares the heck out of me, and at least for the near term I won't need to use the PTO. I do use the lift for my arena groomer.

Today I looked closely at the Over Running Coupler, and I can't figure out how the darn thing is connecter. Two zerks are all I see on the shaft.

Any advice or suggestions would be appreciated.

Thanks.

Take the zerks out, line up the roll pin, and knock it out the other side.

A 20 penny nail ground flat on the end should be a good punch (drift), ifn you don't have one on hand.

Well, I wouldn't have figured that out on my own. I'll sure feel a lot safer with that darn PTO covered. Thanks a lot Dunk.

You can have the best of both worlds.

Great idea! Thanks for the pix!

I need to make one of those thingamabobs bad. I never take the ORC off anymore.

Here is a re-print of a post I made a couple of years ago on building an ORC cover from a tiolet flange:

Agricultural engineering – ORC prophylaxis

Having an ORC (Over Running Clutch) on the PTO shaft for brush hogging adds a good measure of safety. Having that additional length and girth of the ORC down there in the open air spinning at 540 RPM’s with fingers, arms, shoelaces, sleeves and the like in the way is not safe. I posted the question the other day about ORC covers and received a number of great responses including some ideas for building such a cover from “Crem” and “Heybusdriver”. Both of those guys built one out of steel and did a fine job of it. Thanks much guys. Unfortunately, I do not own a welder and having it done just isn’t as much fun as doing it yourself. I decided to make one out of 4 inch, schedule 40 ABS sewer pipe. There is something poetic about having a chunk of sewer pipe hanging off the rear of The Beast!

I first made some studs to replace the bolts that hold the limit chain brackets out of 7/16 – 14 all thread. I used 2 jam nuts to provide a spacer between the limit chain bracket and a 4-inch ABS “Johnny ring” flange. The flange bolt pattern is very close to the 4-¼ inch pattern on the limit chain brackets, I just needed to drill out the flange to accept the 7/16 studs. I then glued a male threaded connector on the Johnny ring and cut a short length of pipe and put a cap on it to allow for easy removal.

Now I can keep the ORC in place while using other implements without the worry that someone can get caught up in it.

Finally got to removing the ORC. Removed the zerks, lined it up and drove a nail in - and a greasy nail poked out the other side. Typical of a lot of things on this tractor, no roller pin.

Still can't figure out how to get the darn thing off. Feeling like a dull tool right now...

Didja know that roll-pins are HOLLOW? (You have to engage it on it's outer-circumferential-edge.)
