Hi Kev great to see you and your looking well and got the new workshop sorted it’s fantastic to see that you’re now doing more informative videos again and with super dexta engine and look forward to seeing more 👏👌👍
The combustion chambers warp around the bolt holes because the original gasket only covers the center part. When tightened down you get uneven pressure. Just replace them or file around the bolt holes and the outer edge.
Hi Kev, I've finally reached the point where I HAVE to recondition the engine in my boat. it's become a gassey health hazard and I plan to sail around the top of australia sydney to perth, not if it has - blow back , oil leaks , rear seals and all the usual suspects! It's a super dexta so your videos are fantastic for giving me the confidence to go ahead. Your calm matter of facts and the tips along the way are really inspiring me to go ahead and get into it. So big props to you and thank you so much. I have ordered a new fully fitted super dexta cylinder head from jskautomotivenew I hope it arrives, they are all the same and it fits right on. the only super dexta parts I can find on the emmark website is a fuel pump - one of which I have already bought from them as well as a full gasket kit. Do you know if emmark can still supply a rebuild kit - pistons, rings & sleeves at the least , I would love a new cam and crank shaft too if available ? can you help source any of these ? I can get 3.144 perkins re build parts but I think thats a different motor , right? many thanks - Fergus
When we went through the head of our MF35X we were unable to make the pre chambers seal properly with the normal gaskets since you can’t get enough pressure on it all. So instead we bought copper and aluminum washers with the dimensions 33.3x38.9x2mm, that way it seals inside on the cup instead. We put copper and a new cap on one, copper and old cap on one and aluminum and new cap on one and 250 hours later they are all still tight, no mystery goo used.
