961D Workout

I worked the 961 for a good two hours this morning. Ran good. Hot oil pressure is a little lower than I would like. Hot idle is about 20psi. Quickly goes up to 40psi when throttling up. Should I consider using a heavier oil (currently using 15W40)?

Colin, I think you're right on the money both idle and working oil pressure.

I wouldn't change the oil weight either.

Nice looking tractor!!
 
Tractor looks great Colin!
I can't really weigh in on the OP for those old diesels.
All I've ever owned in that vintage is gassers and I don't know
if they should be the same or different when it comes to OP.
 
Thanks! This is my first hundred series. I've dabbled with Ns and this is quite a step up. Thanks for the info on the OP.
