Oil Pressure and flow?

[cabu]

Hello,

can somebody tell me some specifications about the oilpump of the D850 engine of a Kubota Traktor (B1502DT)?

Are there different types of oilpumps sold with the D850?

I would like to know the max pressure und oilflow.

And secoundly: how to adjust the pressure (B1502DT)?

Can somebody help?

Thanx

carl

I have an engine manual at home --- let me look tonight and I'll see what I can dig out for you. I don't think you can adjust the oil pressure.

Here's what I get from the engine manual. At "rated speed" min oil pressure should be 28 psi and max should be 64 psi. At idle minimum should be 10 psi. Oil pressure light activates at 7.4 psi.

I see only one oil pump option --- it's a "rotor inside of a rotor". I see no ability to adjust oil pressure without rebuilding the oil pump to original specs and/or reestablishing original spec crank and rod bearing clearances --- all of those options, by design, should increase oil pressure.

I can add that I run a D950 and it runs about 50 psi at rated spped and 35 psi at idle both at an engine temp of 170 deg F.

Re: HYDRAULIC Oil Pressure and flow?

Sorry Sorry,

It looks like everybody understood the oilpump for the engine.

I was looking for the Hydaulic Pump connected to the D850.

Are there different Type's used at the Traktors (D850)?

What is the Pressure and Flow of the Hydraulic?

And where to adjust?

Thanx for your Help bruceatlam !!

Sorry for that
