Re: Oil Pressure Volvo D3 I - C

Dirk Hooff

Hi Paul, Ralph, Mohammad and Arno,

thank you for your answers and your experience.

We connected an external gauge and the pressure is with cold engine at 2bar at 700rpm (idle) and 4bar at 1500rpm.
After 15min. with normal oil temperature (75degree) the oil pressure drops to 1.3bar when idling.
And 3 bar at 1500rpm.
The Volvo expert thinks, that this is not enough.
Actually the oil pressure sensor should not trigger before the oil pressure drops down to 0.7bar. That´s why I think the old sensor is too sensitive… 

First I will try it with a new sensor… unfortunately it needs time to get it, and maybe someone of you have some experience with the oil-pressure with a warm engine…

Thanks and take care,

I just had the same problem. Connecting an external gauge the pressure is normal, so I’m getting a new sensor. Note also that you cannot use a normal Volvo sensor, you must get the specially modified one that takes the bonding connection from Gwen Marine Service in France - €78.

Hi all,
since yesterday I have an oil pressure problem on my AMEL 54#96.
When I go from normal speed to idle, the oil alarm starts.
Of course, this doesn´t happen in the port but between the islands in Croatia.
My German Volvo expert suspects that the oil is too thin.
Diesel has probably gotten into the oil.
That´s why I changed the oil. More than 7 liters of very thin oil came out.
Then the engine ran again without an oil pressure alarm.
But today, when I switched back to idle, the alarm went on again.
I appreciate any advice or experiences.
Thanks a lot,


Currently Croatia close to Dubrovnik

Subject: [AmelYachtOwners] Main furling motor and gear on 54

I know this has come up before, but I am servicing the main sail furling motor and worm drive. 
It is all well but the top shaft seal should be replaced. 
Shaft into the worm gear is very tight. Soaked it in diesel for some hours, hesitant to hit it. Plan to find a press to press it out. 
Does anyone have a better idea?
