I took the water pump off a Massey Ferguson 35 with the 4 cylinder Continental engine on Friday. It was on my farmer friend's tractor, and I don't charge him. I tried numerous ways to remove the water pump pulley but it was very stubborn. I told him I would be back Sunday afternoon, but he ran it down to a tractor dealership to get it done sooner. He said a young guy took it in the back and returned in about five minutes and said the pulley just broke in the press. It is a $200.00 pulley which they had to order. I should have taken it home and heated the pulley neck in my shed. Hind sight.
