I have a kubota b2910. The transmission oil plug bolt on the bell housing has a slow leak. This original plug and bolt was stripped out and a new larger bolt has been tapped in. I have tried several different washers to stop the leak, i.e., a teflon washer, a washer with the rubber lip inside the washer, a copper washer backing a teflon washer etc. Twice now, I have stopped the leak for about a week, but then it starts again.
I believe the threads on the bell housing may be worn. One option is of course replace the bell housing, but that's and expensive option.
I consider using teflon tape on the washer, but I wonder if that would be an issue if pieces of that tape came off into the transmission.
Are there any options? I was wondering if there was a coating I could put on the bolt threads to provide a tighter seal?
thanks for any advice.
