Two bolts and a stud hold this water pump on.

IS THE STUD THREADED SO THAT IT CAN BE REMOVED FROM THE ENGINE BLOCK? It's difficult to tell by looking.

My tractor was a D14, but that stud was threaded on mine. If series 1 D15, probably same engine and set up as my D14.

yes the stud should be threaded. May be loctited into place if it goes into the water jacket

I ended up just retapping the stud and I think it will hold.
