MD1,MD2B and MD3B

Engine Manual can be downloaded from here

A very simple easily worked on engine robustly made. Uses raw sea-water cooling and with practise it can easily be fired up by one person using the starting handle and decompression levers. Each cylinder is a separate unit and can be serviced without disturbing the rest of the engine. The only difference between the 1B,2B and 3B are the number of cylinders. The workshop manual covers all three engines.


Flywheel

The flywheel is tightened to 500 lbft!(700Nm) This is seriously tight and needs proffessional equipment to undo it. When the nut has been removed, tape over the screwthreads in order to protect the threads when lifting off the heavy flywheel. The threads are very fine and can easily be damaged. Do not under any circumstances imobilize the engine by trapping the starter wheel teeth with a screwdriver. The force needed to release the flywheel nut will break off these teeth


Oil Pump

With care it is not necessary to remove the flywheel in order to remove and refit the oil pump. It's tight and fiddlely and needs patience. Do not forget to prime (fill) the oil pump before refitting otherwise the engine runs initially without oil in the bearings.


Oil Strainer

If this comes loose the engine will lose oil pressure and illuminate the oil pressure light. If pressure is lost always check the strainer tightness first.

Check/replace aluminium washer on strainer.

MD 7 Series

Engine Manual can be downloaded from here

This is basically the same engine as the 1,2,& 3 Series with very minor differences. You can also refer to the MD11 manuals at the above link. If someone knows what the difference is please contribute here.

Volvo 2002 Series Engines

Alternator "vee" belt : Volvo 966900/Marine+Leisure Supplies no. (GATES brand) GFB6213MC

Impeller :Johnson 09-0808B/ MLS no. 121

Cold Start Procedure

With all usual items turned on ( cooling water, electrics etc) :

  1. Press IN the drive "disengage button" on throttle handle, then give it at least 3/4 throttle, either forward or in reverse;
  2. lift "STOP" handle (strangler) fully up, then steadily push fully DOWN to engage the "rack" giving extra fuel delivery.( on very quiet days, you may hear a "click" from the diesel governor/throttle mechanism "box" on the stbd side of the engine-- follow the cables along)
  3. do not move throttle lever until it starts or until you repeat the strangler procedure, as this may disengage the "rack".
  4. press starter button or key; let revs build a little after start , then throttle back a little.
  5. When engine warmed up a bit and cooling working OK, it is best to run engine in gear if you possibly can (to minimise bore glazing) by putting a "load" on it.
