removing the cam wheels ect

[tckearney]

Good day.  I have a very small water leak from the freshwater circulating pump  Bavaria 42 2000. .  This is behind the plastic covers on my MD22 55hp.  I have started the job and removed the cam belt, with all pulleys locked in position but cant remove the main crankshaft pully.  Is there a secret to getting the main lock nut off.  The boat is in the water so I cant put it in gear and lock the prop. How do you lock crankshaft so I can undo the nut.  Also I cant figure out how to lock the fuel injector pump once the injector drive wheel is off.  Is there any U tube videos. Thanks Terry.

I believe MD22 workshop manual from may help https://nikimat.com/volvo_tmd_22_workshop_manual.pdf. Furhtermore some tips on how not to use Volvo special tools and still manage locking all timing components (incl. flywheel) are described in timing belt change DIY instructions at https://www.jeanneau-owners.com/hintsandtips/volvomd22lbtimingbelt.html.

..preparing for timing belt change within the next one or two seasons... have these links at my bookmarks

I can recommend getting the Haynes manual for the Perkins Prima (which is what the MD22 is, with some minor modifications around the heat exchanger):



Helped me a lot with this sort of job. It has all the right size drill bits that you can use instead of the Volvo special locking tools

Maybe too late, but still. I had the same problem when I was changing fresh water pump on my MD22. So, I just cut the cover above crankshaft pulley, so I can remove upper part of the cover (with all other pulley removed) and replace the pump.
Then I screwed back the cover. Yes, there is small crack on it now, but this saved me a lot of time and efforts.

On the MD22, you can remove the cover without removing the crank pulley, you just have to wiggle it a bit.

I have MD22L-B, and it was not possible to remove the cover with pulley installed. That is why I decided to cut it, which I think is not a big problem.
