Hi All,

Have a westerly conway with a mercedes om636. I was planning the removal of the stuffing gland to either repack or replace with PSS shaft seal but having reassembled the coupling having gotten it slightly apart was checking things over and noticed a small drip from the fuel injection pump. I might just leave it or take it off and fit another 2nd hand one I have or have it rebuilt. However I will have to lift the engine out on to the cabin sole or cut a hatch way in the engine compartment. Anybody lifted one of these engines out and any advice about how to approach it. It must weight a ton, literally!

Thanks

In advance.
 
cant you just lift it and turn it over enough to get at the pump, this would be simple enough using levers and planks of wood
cheers

If you fit a shaft seal could you post with your experience of fitting it. Tips and pitfalls you encountered. Reason: we have a Conway and thinking of fitting one. Many thanks. Paul
Good luck with lifting/moving engine - I know what you are facing !
 
Hi Stav

The chap who lifted my Merc out of my conway used a strong steel tube, ( think it was an old Acro prop )
one end resting on top of the fuel tank, and tother end on a rope/winch/wooden post arrangement to top of companionway .

He had a large roller/bearing thingy that was able to roll along the steel tube, This was connected to engine.

By winching up the end of the steel tube , was able to lift then pull engine out
to cabin.

( I think that whats he did cos I was not there at the time )

That sounds like a good idea, but I think I'd want a board on the top of the fuel tank to spread the load.

I'd also want to check that the tank mountings can take the weight (I've no idea how ithe tank's fitted on a Conway - it may not be a problem, but my nasty suspicious mind has saved me a good bit of money in the past - and cost me a good bit when it wasn't suspicious enough!)

Yes he did use a block of wood on top of my fuel tank

I have a very sturdy aluminium fuel tank, which sits on a thick ply floor.


BTW Storyline. I have been using PPS seals for the last 10 years, no problems ... so far :)
Easy to fit, as long as the prop shaft has not got any bad burrs/dents

Good news - its going on the list !
 
Thanks for the suggestions: have had family staying so have not been down the boat but will look at the suggestions and if/when fit a seal will report back. I have had it suggested that cutting the hatch is the best route as will be useful in future and to check it is diesel leaking from the injection pump and not just lubricating oil.
