Got another question, oil pressure this time.

I have a 4430 with 7000 hrs, doesn`t use a drop of oil.  A couple yrs ago the oil pressure gauge developed a "quiver" on the needle, I use it for light duty work and if it had a "idiot light" you`d never know it had a problem.  Is the problem perhaps the gauge, given that the motor is tight?   I use JD 15-40 oil, change every 60-70 hrs.


Also, I have a truck with a 427 Chevy motor, the oil pressure is good at speed or "cold" but warm and idling it drops to 22lbs, it`s done that for years and been okay.  Mechanics that I talk to say "that is normal with that motor".  I use the recommended 10w-30 oil.  It just seems to me that 22lbs is scary low, but again if it was a idiot light, you`d never know.   Thank you.

I think you got a good answer already ------ bout have to be in the sender or guage.  Sounds like she's still good to go.


I was going to tease you about changing the oil every 60-70 hours.  If the oil pressure guage is quivering maybe you have created an addiction to clean oil.  


Those are good tractors.  We pulled ours hard for many years.   They were well matched for power, weight, and traction when we dualed them up.
