Testing a Factory PTO

04 KW with a 13 spd. freedom line and factory PTO. Driving it home I thought the switch was for some kind of defroster, and turned it on a few times. Turns out it's for the factory PTO.

Did I smoke the PTO? How do I test it? I'd like to put a wetkit on the truck but am not interested in replacing the PTO if it's hashed now.

Is there a way to remove some plugs and check the flow rate or something?

Thank you.

 

Thanks for your reply. I don't know about a lock out. I do know that the switch is for the PTO. The local KW dealer confirmed it's for the factory PTO a while back. I also know it's equipped because the last ECM dump I did showed PTO hours.

As soon as I mention checking the "PTO" to the KW service department I see dollar signs rolling in their eyes like the cartoons.

You'd think it'd have a lockout, yes. That one switch, however, is the only PTO switch in the truck.

 

Kenworth checked the part number and also confirmed it. There must be a safety lockout. I sure hope so.
