Hi folks- I have a mysterious antifreeze drain behind and below the oil filter housing on my Bobcat 773 ( 2001 model ). There is a rubber sleeve 'plug' over this 1/4" or so diameter tube that sticks out about an inch and a half on the bottom part of the housing where the oil filter screws in. The trouble is, the rubber plug has a hose clamp over it that leaks every year. Trying to find a replacement plug from Bobcat has not worked so I just keep replacing the rubber 'plug' with a store bought one. I can't find the correct part on the Bobcat parts diagram. The service manual shows only a drain way up on the block, not on the oil filter housing. I'm thinking that a part was lost here years ago and just ' plugged ' , but it's a bad spot because coolant just drains out completely here when this leaks. Does anyone know if this is indeed the low point drain for this machine, and what is the correct part that should go here? The metal tube that the rubber covers and plugs has a small lip on the end of it like something is made to press onto it. Any part number greatly appreciated too. Thanks

AJ did you ever find a part number for the rubber cap? I am having the exact same problem and the Bobcat dealer hasn't been much help so far. I took a shot and ordered part #6652591 (now 66674250) but it is a threaded metal plug.

Don't know if anyone has solved this puzzle yet but I just went thru this today and found there is an alternate oil cooler that bobcat had a problem seeing. The part number for the actual rubber plug is 667123.i hope this helps someone else.
