[C320-list] Yanmar 3YM30---access to adjust valves

[John Van Vessem]

Len,
 
I have had the valves adjusted as required and the valve cover comes right off to expose the valve adjusters.  I don't know where the comment about draining the cooling system comes from.  I think you might want to ask your serviceman if he is familiar with Yanmar.

Awhile back someone wrote that to adjust valves on the new 3YM30 a bulkhead
must be removed (about 12 screws) for access.  My engine just had first
50-hour service (at 65 hours) and Yanmar serviceman didn't adjust
valves---wrote he would have had to drain the cooling system to get to
valves---which sounds strange to me.  Before I confront him---anyone have
their 3YM30 valves adjusted, and how did they get access?
