This morning I went out to start my Case 224 and got a messy surprise. It started fine and I let it warm up a few seconds then put it into reverse. There was a hesitation then the pump made a slight whine. I immediatly shut it off, put the axle in neutral, and pushed it out of the garage. I was shocked to find the short hose to the cooler had a hole blown in it.

Earlier this year I replaced both hoses to the cooler becase they seemed a little soft and mushy. The hoses I replaced were 3/4" Dayco heater hose so I used the same thing. I'm thinking the previous owner may have had problems somewhere along the way and installed these hoses. I don't know if letting the machine warm up would have avoided the problem or the hose I used just wasn't up to the task.

What does everyone else use for these hoses, and how long should I let the machine warm up in 35* F weather?

Thanks projectnut

The hose you are using is not correct. Heater hose is not compatible with oil and will fail in short order.
You need to use a hose that is compatible with the fluid in your system.

Thanks everyone. Now I know why the hoses I took off looked so new yet felt so mushy. I just got back from the local Fleet Farm. They have hose that looks identical to the hose I used but is clearly marked HYDRAULIC. Hopefully this afternoon I can get the mess cleaned up and some new hoses installed.

Well the beast is up and running again. It didn't take long to remove the old hoses. The new ones were a bit stiff in the cool weather so I gave them a shot of warm air with a hair dryer before slipping the ends over the tubes. I had to add 7 quarts of oil to the system which explains the big mess on the garage floor. I took it for a test drive then put it to work for a little while. It's now back in the garage until it gets called back to duty next weekend. Hopefully next time there won't be any surprises and I can get a few loads of wood hauled in a couple hours rather than a couple days.

Thanks again for all the help, projectnut
