I know others with similar convertibles will help with your other questions; the vacuum "motor" is the engine itself, it uses manifold vacuum which probably also passes thru a vacuum booster pump incorporated into the fuel pump but when the engine is idling, your solely relying on the engines intake manifold vacuum. An engine in good condition and proper tune should give 18-20 inches of vacuum at sea level, you could check this with a vacuum gauge attached to the intake manifold.
In addition of whatever Packard may have published, older Motor's Manuals have a good section of vacuum convertible top operation and service.

There are a couple of illustrations of top mechanisms in the 35-41 parts manual which may be of some help figuring out where things attach although neither is what I would consider detailed. I remember a local guy that had a 41 with the vacuum top. Operation wasn't that great and required a hand assist to make it go up and down -- most likely due to seriously worn and leaking cylinders. I would expect at the least you will probably have to rebuild or reseal yours.

Hi; i have rebuilt the vacuum cylinders on my 42. Not that hard to do, I am sure the shafts have some rust and if they do you will have to have new ones machined. the seals can be replaced. The pistons on mine only needed to be cleaned and lubed with nets-foot oil. I can take some photos for you, but don't want to take out the interior. I would guess the the springs will have to be made if you can't find a set. The fellow who is remaking the bottom of a 120 (see posts)should have a photo of the retainer for the bottom of the spring. i am getting my 42 ready for a show and will take some photos. Dell

I would really appreciate any pictures you might have of the top springs and their mounts. Also the vacuum canisters as well. I am having a dustcover made for the top boot this next week and hope to get some information from the upholstery shop.
