I've owned an SR2 6.5Kw US Dept of Transportation, US Coast Guard Long Endurance generator set for a few years. It's been covered with a tarp in my back yard.
Well, this week I started on that project. I moved it to my rural place, put it in the shop, and checked it out. when I hit the starter I got a nice CLUNK!
So I stripped the top down, it's got a rusty cylinder, the one near the flywheel. The crank turns freely now, and the journal looks good. The inside of the engine also looks good. I'll put the cylinder in a press and push the piston out the bottom to see what's salvage and what's scrap.
I figure to replace both rod bearings also the rings on the undamaged cylinder. The damaged cylinder and piston probably will be replaced, maybe as a power assembly kit w/ piston pin & rings?
disassemble the heads to check the valve stems and guide. Clean everything. The cooling fins were about due for a cleaning anyway.
This is entirely my fault, the genset was a runner when I bought it.
I'll be calling Dieselman soon enough...
