replacing push-button motor
Posted by Randy Berger On 2011/10/16 5:07:55
The six-connector relay failed me at a car cruise and supplied power to the push-button motor to position it toward reverse. I could start the car, but could not shift gears.
After much head-scratching and going over wiring diagrams in my mind, I pulled the relay and opened it up. The one standup with a contact point on it had gotten so hot that it laid down and contacted the standup that supplied power when the relay closed. It ran the motor past the reverse detent and locked it up. ACOlds stuck with me and drove home to get jack stands and stayed with me till friend Al showed up at 1:30 AM to flatbed me home. It's nice to have friend, even better to have Packard friends! As the car was stuck in reverse when we unloaded it at the house I was able to back it into the garage. This all happened the Thursday before the HBJ tour in New Jersey. I drove my Honda van to the HBJ tour and good friends Dave Czirr and Ole Book allowed me to ride along with them. I enjoyed the tour immensely thanks to two very good Packard friends.
Back home I knew what was involved to pull the PB motor and finally put jackstands front and back and crawled under Best Other. I dropped the driveshaft and placed a scissorjack under the tranny. After supporting the tranny with the scissorjack I dropped the rear motor mount. The shop manual states that you have to drop the tailshaft to enable you to jack the trans to the passenger side giving enough clearance to pull the PB motor off the selector shaft. Friend Dave Czirr told me that he was able to pull the PB motor without removing the tail shaft. It was worth a try. It worked - although it is a very tight squeeze. What did I say about Packard friends?
I also checked the leather ring seal? and it seemed to be in good shape. Seal is group 3.577882 (6470206).
Seal is .385 wide
Seal is .100 thick
Seal is 3 3/8 inches long
I've attached some pics of the install.
