When I fist got my Packard, the w/w were inop. Reading through some postings here, I discovered a procedure that made my w/w motor operate almost as if it was new. The procedure was as follows:

1. fill a container with 'hydraulic tool oil'

2. diconnect the w/w motor's vacuum tube from the source, leaving it attached to the w/w motor.

3. put the free hose end into the container with the oil.

4. manually work the w/w's by moving the w/w arm briskly back and fourth through their entire sweep. This will suck the oil directly into the motors vacuum chamber and lubricate the various seals.

5. reconnect the vacuum hose.

I had to wait overnight and do the procedure a second time before it worked correctly.

It also helps to replace all of the hoses to prevent any vacuum leaks.
