Neatsfoot oil whatever that is.

Yes, I was told neatsfoot oil was the right stuff, but couldn’t find any on my shelf in the workshop!

When renewing the leather gaiters that surround the swivel hubs on my ex military Land Rover lightweight I impregnated them with copious amounts of vaseline, which made them pliable, water proof and slippery, which sounds like the spec of what you are hoping to achieve.

I've obtained a small bottle of Neatsfoot oil to treat the leather cups with. The question is how much to use and where to apply it ? Directions for use welcomed.

Put some in a saucer and soak the leather seals in it overnight. Wipe off the excess and fit the seals.

A thought occurred to me when restoring this vacuum wiper motor. Why not make a vacuum tank that is plumbed into the vacuum tube between the engine and the wiper ? Perhaps a one- way valve on the suction side to maintain the vacuum.
What are your thoughts or experiences?
Cheers,

Steve, I've spent most of my career in brake systems and - as I'm sure you realise - that's how brake vacuum servos are done. I guess the main issue would be where to put it. A simple plastic NRV on the engine side should suffice to retain vacuum in the reservoir - assuming everything else seals adequately. From a "design" side the thing you'd have to figure out is how big is enough? I have no idea how much vacuum is 'consumed' by the wiper. You could potentially end up in a dead spot where the vacuum in the tank is quickly exhausted and the suck from the engine is insufficient to evacuate the tank back to a level where the wipers work properly (maybe - just thinking out loud).
Another possibility - for those who are hell-bent on making it work and perhaps less concerned about originality - would be a small electric vacuum pump. That could probably be installed out of sight somewhere and should guarantee a steady 'suck'.
