There is a restrictor in the fitting going into the PSRU.

The RWS RD-1C manual specifically states: NO restrictor in oil supply line (unlike the Ross drive).

"22. ... IMPORTANT: Unlike the Ross Drive, no restrictor is to be used in the oil feed line!"

The RD-1C is designed with bearing and other clearances to use full oil pressure and flow.

If you don't have a copy of the RD-1C Gear Reduction Drive Installation Guide one of us will be happy to get it to you.
