Re: oil pressure high
Welcome to the Forum!
What weight oil are you running? Does the pressure drop at all after the engine is warmed up?

Re: oil pressure high
Either you have a bad gauge or the relief valve is stuck , If the pressure does not drop back some after it has wormed up.

Re: oil pressure high
Hi people,
My gauge does drop down after i shut it off,what worries me is that i dont remember it being that high when i bought the tractor. I since changed the filter and oil (30w) and its still high should i be concerned?

Re: oil pressure high
Easy no cost check for stuck oil pressure regulator valve. Start engine and get oil pressure up. Stop engine. Remove the cap on the oil pressure regulator, remove the spring. Replace the cap.
Start engine at low idle, observe the oil pressure gauge for 15 to 20 seconds. Stop engine. Remove the cap to the oil pressure regulator valve. If valve is now located in the back of the bore, next to the cap, valve is not stuck. Could be that the spring has been replace with a much heavier one.
In case the valve is stuck. Post back, we have a valve removal method/tool.
Although once functioning, the valves seldom stick when the tractor has been relatively frequently operated.
My guess is the fault is the oil pressure gauge.

I have an excuse. CRS.

Re: oil pressure high
Front right side of the engine, behind a "hex cap", just above the water inlet line.
Tried to final a photo that pointed it out, but had no luck.

Re: oil pressure high
Remove that hex bolt, and behind it will be a spring. This spring pushes against a plug and is what regulates the pressure. If the plug is stuck, there will be no relief and it will cause high oil pressure.
Open it up and have a look. If its stuck and you can't get it out with a magnet on a stick, come back and we'll show you a trick to get it out and cleaned up.
