Orc noise

Craig Andrus (TX) · Mar 19, 2017

I changed my pin type Orc to a quic disconnect type that looks exactly like the one Caryc uploaded a pic of recently. 13/8 to 13/8. It drives my rotary mower fine, but when I depress the clutch it begins to make a heavy metal on metal sound. It is not the ratchet clicking, much more like grinding. If I flip the pto lever off, everything back there is still spinning but the noise goes away. Put the pin type back on and all noise goes away. Any idea what is happening? 8n FM if it matters. Thanks.

Got plenty of grease in it. Just wondering what the difference in power going to the PTO when the clutch is pushed in vs pto being off. I think my pto splines must be worn and are slipping inside the Orc with the quick disconnect, but the pin on the other Orc prevents this

For it to slip, freewheeling, it would for sure slip driving, and you'd be missing lots of metal and that would be easy to see.

Yes, that makes sense. It's a head scratcher. If I find the solution I'll post back. Thanks for the reply.
