Safety Recalls
Japanese manufacturer safety recall affecting the differential. Declared production window: 2011–2012.
Known Issues
Water pump impeller broke into 3 parts during heavy load operation, causing coolant temperature to reach 120°C. After replacement, coolant shows bubbles and milkiness during operation that clears when engine stops, suggesting possible head gasket issue.
After water pump replacement, coolant exhibits bubbles and apparent milkiness while engine operates under load, returning to normal appearance when stopped. May indicate head gasket failure or air in cooling system.
The water pump on my JD6230 tractor stopped working under heavy load and the coolant temperature was 120C before i noticed. The impeller was in 3 parts. I replaced it and mostly everything seems fine(i followed the repair manual so i am reasonably sure i did it correctly). There could of course be leaks from outside, but there is no apparant coolant leak. But i am concerned about the bubbles and apparant milkiness of the coolant during operation. When i stop it turns back to normal. Could anyone help me diagnose if i am lucky enough to also have a blown head gasket? Or is this video showing normal operation?
