Re: Bukh DV10 General questions & inquiry

I actually have a "Machine Shop" in my workshop so there isn't a job i can't do. I simply never had a boat before so everything that "seems" incorrect i wanted to report. Will definitely check alignment and probably strengthen the engine mount it self on the boat with fiberglass.

Was thinking about extracting the oil like that so will do that tomorrow.

I am still peeling away he old paint on the boat in the V Berth as it seems it was laid with no sanding and th epaint is just falling off by chunks with not much effort.

Solid mounts are usually laboriously adusted by shimming the mounts until the flanges say you can bolt it back together. Shims can be hard wood or flat plate/sheet metal. Rubber mounts help with vibration and alignment but movement is transfered to flexing the shaft. Grease packed seals are common in Scandawhoivian installations. Some greases can cause electrolysis. I remember one turn of the cup each watch.and repack for sure when needed.

The big flywheel also aids in hand cranking. we had one years ago and it had an oiler for the cyl head, put a small amount of oil to boost compression open the compression release pull out your man card and spin as fast as you can let the release off and if its warm outside maybe it will start. Not something you want to count on for sure.

The oil in the gearbox is something i didn't change and from the documentation it looks like it uses the same oil as the engine but the level in the gearbox seems to be really high. Pretty much double of what the dipstick shows. I assume whoever pored it in, filled it up to the brim. I have limited access to the bolt to empty it so for few days will leave it as is.

One thing i did notice is a slight wobble of the shaft where the "Lubricating" coupling interfaces. The shaft i would say goes up and down about 1/4 of an inch. Is this something i should be worried about? I don't run the engine too high and mainly use it to get in and out of the marina.
Having too much oil in a gearbox can be just as bad as not enough,too Much pressure blows out seals ,something as simple as a gear oil vacuum/syringe as faster suggested is all you need if the drain is inaccessible ......Ralph
