I'm changing out the engine in my '42 coupe, and have the Vacum shift unit off. I would like to lube the piston while it is off. What is a good lubricant? The book calls for shock insulating fluid? I'm thinking Neatsfoot oil. but I haven't seen any of that in years.

Neats foot oil is available at most saddle shops.

It's as poplar as ever... Get yours @ Walmart/Lowes/AceHardware/etc. ....Amazon, too.

So, your just assuming, right...? That neatsfoot will do...?

For my shocks, I use hydraulic jack oil.......


Sooooooo, why not use hydraulic oil in the vacuum cylinder as well?

I actually shoot some WD40 into my vacuum shift cylinder from time to time.
I think any light oil that won't leave a sticky residue when it dries out will probably work just fine.

I do not know. that's why I asked. As far as it being avialable. Probably so, I have not looked for it in years/.

I am also debating on how to soften the boot before trying to get it on the cylinder.I was thinking maybe hitting it with the heat gun a bit..What do you think?

After doing some internet searching it seems GM Insulating Shock fluid was mineral oil based. So I guess I will go with mineral oil.

Another suggestion about dealing with the new boot. I kept a rag with lacquer thinner on it to wipe my hands with and keep my fingers so they could work the boot. The rubber gets way slippery and difficult to hold onto. Another set of hand helps and have a small wooden dowel handy for your helper to hold things down as you go. I didn't want to use a screwdriver because I thought about the possibility of poking a hole.
Good Luck
Don
