Does anyone know of a source for the spring that regulates hydraulic pressure(part number: D65B046-5)?
This spring applies pressure to a small plastic ball and mine has weakened and been shimmed with washers as much as possible. It now needs to be replaced. My mechanic was able to get the plastic ball from Joan Diver. It had to be replaced as a result of scoring.
Make sure your pump is good also could be loss of pressure from worn seals in the pump the spring will usually compress and coil bind with lots of shims “washers” and pressure will go up , probably to high ouch!
