Had to pull a leaking oil pan off a Case 855E the other day - it had a hole worn in the bottom of it. :rolleyes:
As I pulled the last bolt & lowered the pan from under the machine, it had one of those rattling noises in it that you know is just not right.
It came as a surprise because the engine was running perfectly with no worrying sounds at all.
Well, what I found was a main bearing cap retaining bolt. Looks like the head had popped off & the remaining stud had fully unscrewed itself & fell into the pan.
The bottom of the pan & bolt/head are very highly polished - I figure it has been in there for a couple of thousand hours. I fitted this engine as an exchange unit from Cummins about 6 yrs ago.
Pulled the main & checked it out - couldn't see any problem with the cap or bearing.
2 x new bolts & a new pan were fitted - & it's back at work.
Some people are just so lucky.....
