I am looking at getting my oil pressure gauge refaced and have a question:
According to the TCDS the A65 has OP limits of 30-60 PSI, while the A75 has limits of 30-40 PSI. Does this seem correct? If so, why the lower top end limit for the A75? I did the A65 to A75 conversion (years ago) and don't recall any changes to the oil system.
On a related note, when you all have Cub instruments refaced, do most of you have operating range markings installed? I don't think there were any in 1946, except maybe an airspeed redline. I can never find the right Barn Cub picture when I need it!
