Default Re: B6000 making metal in the oil

Thanks Wolf.
It runs ok but as the post title says it's making metal and the oil pressure when hot is down to 20 psi. 80 psi cold.

Looking at the parts list it shows two bearing sets say for the mains. 1 and 2. Each set has a different part number hence my assumption one set is undersize.

I'm looking for a definition of the different part numbers for the shells.

They are very vague in the parts description department, all I can say is 1 and 2 are different bearings in different locations on the crank, or they are halves of a pair.

Tear into it and find out what it is then go from there.
Is there any chance your gauge or sending unit might be lying to you?

Pressure gauge is good. I'm now searching for an engine manual for the ZL600 engine but not having any luck.

I do see that Stavros in Cyprus does list aftermarket bottom end and rod bearings in .25 and .50mm undersizes.

Cmon,, pull an engine manual out of your pocket! Of course I'll need the dimensions and clearances for the shop to grind the crank to. I'm assuming the crank is worn as the metal on the magnet is a very fine particle size.

According to a spec sheet I found somewhere on the web the mains measure 1.9659" or 49.93mm. Assuming the bearing insets have a 50mm bore diameter that will present a clearance of .07mm or .1778" which sounds about right.

It's all down with some expected crank wear although not too bad considering the joke that is considered an oil filter. It's out getting reground for .25 bearings on mains and rods. Parts are filtering in with liners pistons, oil pump body etc. Injectors are at a diesel shop for new nozzles etc.


I have a question on the pistons. There are no markings on them whatsoever other than internally with the manufacturers name IZUMI on one skirt boss and likely the die number 6 on the other. Can I assume they can be put in either way? Do they have offset pins which must be oriented correctly?

Hey guy, can you send me a picture of the pilot hole for the crank? I need one to show the machine shop what it is supposed to be. Mine has been bored out to almost 1 1/2 in.

Are you certain it isn't just a worn pilot bearing your looking at?

They typically are pull out and replaced when doing clutch work.

Just get a stock bearing / bushing for them to use as a reference to repair it.
