930/931 Waste Gate Rebuild


Model: 931, Year:1981, Mileage:59,900, Type of use:Both Street & Track
I have just opened my OEM waste gate to replace the diaphragm. In general the housing and valve are in good shape. I am about to button things up, however inn doing this about 20 years ago on a similar car I had, I recall being instructed to use dry graphite power to lubricate the diaphragm. Is any lubrication necessary or suggested? If so, what lubricant, and on what side(s) of the diaphragm?
