YANMAR 3JH5E SO39i

[nornaj]

Hi, All
Anyone know how to open up the air intake on the Yanmar 3JH5E? The process is not obvious from inspection of the unit. Cleaning the element is mentioned as a routine maintenance item, but there are no instructions in either the operation or service manuals.
thanks

I was also puzzled about cleaning the air filter on my 4JH4-AE. There were references to cleaning it at certain intervals but it just seemed to be an empty plastic box.

I asked my wife's godson as he is a Yanmar dealer and he said it was just as silencer and didn't actually have a filter. Very unusual and never heard of this before. However, I checked through the workshop manual and it does say to clean the filter but only description of how to do it refers to the Turbocharger air filter.

The only text & diagram of the air filter says:
"63. Install suction air silencer of 3JH4E and 4JH4-AE."

i.e. It's a silencer just as he said.

Perhaps the 3JH5E is the same, I'll see if I can find out.
