I was given a 445 because it had quit oiling. I put fresh gas in it and got it running without any trouble. I let it run without a bar for a couple of minutes, and sure enough, no oil from the oil pump outlet. I dumped the tank and check the inside, looked clean & the pick up screen looks OK. I also checked the oiler output adjustment, it is set to the highest flow position.
Now for the newbie questions:
1. How do I get the clutch off? I'd seen something about modifying a socket, but this does have anything resembling a hex to get the socket on.
2. How do I go about troubleshooting the oil pump, other than taking the clutch off and digging in?
I don't know that it matters, but based on the serial number I think it is a 2007 model.
