    If you look @ the chart and look at your pressure on scan tool, you have low oil pressure.

    That isn’t on a c13 is it? Where would be the heat spot to check on a c13

    The pic is a C-12, from the C13 manual though and location the same! Your existing gauge hose is probably in one of the oil gallery plugs.

    The plugs are -6 SAE STOR, some also call it ORB. Any hydraulic place should have what you need.

    Thanks I’ll get back too you after I check the oil pressure if it does turn out low do you think it will be the oil pump or the oil filter base ?

    Something is base, bearing wear, VVA leak, could be number of things. What is your oil drain intervals. Bossman tried 25,000 miles on the C13, but the 1R-1808 tended to plug around 23,000 miles. We went back to 20,000 on tractors.
