I need some help to ask Yanmar
some smart questions about my 4JH57 Common Rail engines.
48 cat is being from Cape Town
as I type. About 2/3s of the way into the +6000 nm delivery
, the crew had to stop and get a Yanmar
tech to look at the engines. Apparently the engines were cutting out every 40 -120 minutes. Engine
temperature was fine and no sign of water
in the fuel
. Yanmar put some new fuel
filters on and everything seems to be fine and the boat has left port and is on her way for the final stretch. Arrival is expected to be September 22.
I have not had the opportunity to speak directly with the delivery
crew but am surprised that they would not have spare fuel filters on board for a +two month trip. So I am worried this is not just a problem about the fuel filters. More importantly I am worried that in the run-up to bringing the boat into port for repairs
, would there have been any more serious damage done. Fortunately, the next two weeks will be a good test for that question.
I have read a lot about the fragility of common rail engines and fuel filtering. If the filters were the only problem, is there any risk that water
or sentiment could have gotten past clogged filters and done more damage?
The engines will have a 2 year or 2000 hour warranty once the boat is signed over to me in a few weeks. But I'd like to make sure I really understand the problem experienced and implications for the engines now and down the road.
So if any mechanically minded owners out there can share some questions you think I should be asking Yanmar, please send them.
Thanks very much,
