Westerbeke 27 Seized - HELP! SOS!

[S/V Antares]

I was mistaken on my earlier point # 3. The flex plate is bolted to the Flywheel I was off my meds on that one. If the trans was a problem you would not likely be able to turn the shaft. I assume a Hurth100 /ZF 10 gear. The older Mitsubishi parts are available (Rings, Bearings) You will need the base engine Modle # which is cast in the block side and the serial # They Mitsubishi) made about 4 versions of the K3. It was heavily used in the Small tractor, Forklift and Turf (Professional lawn care) sectors I used Stauffer Diesel in PA once Nice folks The real pros on the Westerbeke marinization is Hansen Marine in Marblehead Mass. I also like Helseth Marine in Vero beach. Good luck!

How old is this engine? The newer W-bekes are either Kabota or Mitsubishi based. They use the SL3/4 series on the Mitsubishi But this series number is also cast on the block side.

I think it's circa 1986 -- I'll try and find out exactly. that last piston isn't going to move until I do something about the stuff around the cylinder and then I'll likely have to re-bore?

my friend who was helping me thought it looked like the cylinders may be jackets basically that could be removed and replaced....ever heard of anything like that?

Yep, they're sleeves and I believe they're sweated in.

Sounds like a personal problum.....I never get mad after downing a couple good beers..the others come anyway regardless and they will hurt a lot less after a couple as well...

Brian, Many Diesels have replacable sleeves This is not one of them You can get Standard, .25, .50 or .75mm oversized pistons and or rings Rings are reletivly cheap if you can save the pistons. If you must overbore you will need pistons and rings and perhaps more. If you are lucky you can get the piston out and see if the bore will clean up If it is pitted and cannot be cleaned with a proper honing then it is decision time
