Kubota L345 Blown Oil Plug

[carlubu1]

These pictures show a plug that blew out of the block from just behind the hydraulic filter on my Kubota L345. Oil spewed from the hole. I had noticed the plug partly protruding the day before and tamped it back in flush. I used the tractor for about 4 hours afterwards. Is this a pressure relief plug and can I just replace it from theoutside or is something more serious going on?

now was it hyd fluid or motor oil from what i see in the pic it maybe a port hole for a presser gauge ..if no threads it may be like a frost plug ..i would say for sure not a relief valve best of luck

Thanks for the reply. I found an old thread from back in 2006 addressing the exact same issue. It seems all I need to do is replace the plug securely with loctite.
