A6 Case Guys

[Ande]

Can anyone give me a good procedure to "put to bed" the Wisconsin engine on the A6? Not sure if I can get everything running this year and just want to make sure this engine gets extra care.They are pretty fussy.Let me know your thoughts

Biggest problem I've had with a Wisconsin was the exhaust valves sticking at the start of the year. Oil down the shafts somehow. Pull the plugs, reach in with an oil can if accessable, or pour in the exhaust and turn it over by hand enough to spin it through that area. The one we had on our swather required lots of attention to the valves if we didn't get something in there before winter (eastern Montana growing up).

Oiling down the cylinder walls is a good idea, and draining or running some Sta-Bil through the fuel system is nice if you have it running. Sounds like that might not be possible?

The engine on our baler (a newer Wisconsin, NH 282 baler) never had trouble but that swather required yearly attention and sometimes more often than that. At least it was electric start... it would have been a miserable beast if it were a crank type.


Also, try and keep water out of the magneto if it's so equipped. We had a Wisconsin mag go bad because it got wet but drying it out and cleaning the rust out fixed it. Prevention is easier than fixing, right?

Hope this helps.

neighbors would open the priming cock on the intake and pour oil in with the engine running until it bogged down then they shut it off and parked it for the year, they did this for years and never stuck a valve.

Ande,
I use a good top end oil like Marvel Mystery Oil in the cylinders. Take out the plugs and pour two tablespoons into each cylinder and spin the engine over a few times with the crank. Put the plugs back in and turn it over a few more times. Drain all the gas out of the carb and sediment bowl. I have never had a stuck valve on our Wisconsin. Depending on the last time the oil was changed, you may add a pint or two of Marvel to the crankcase also before spinning it. Like mine, your engine probably is not equiped with an oil filter. The shallow oil pan on these engines will build up a lot of sludge that does not drain out when the oil is changed. I would remove the pan and clean it well before you start the engine. I also like to blow out dirt and chaff from the housing with compressed air.
From your pictures, it looks like you"re going to keep the combine inside. Keeping the rain and moisture out of the manifold and air cleaner will help. I have seen the inside of a VE4 that was left setting out for years even with some protection. It had pitted valve seats and a lot of rust in the cylinders.

Today I was talking to the former owner of my "A6" and he told me that some guys told him that squirting snowmobile oil in it and killing it was the best.Another guy said Marvel was ok but dried out faster?? Something about the moisture inhibiter?? Anyway getting some good ideas,thanks all of you for sending them to me
