Lubricant for Sinar F?

[Bruce B]

Hi,

I'm wanting to remove the dirt of the Ages from the shift slides of a Sinar F+ and replace the lubricant. And give both standards a good cleaning in the process. Removing the frame from the shift slide is easy (and reveals the slide could really use a lubricant replacement), but I haven't the slightest as to what lubricant to use. What's on the slides now looks like plumbers' high temp grease, but looks can be deceptive.

Also, there's a noticeable (though not horrific) slack in the focus rack on the rear standard. Any suggestions for tightening that up would be helpful. I suspect this might involve a new rack, since it appears to be nylon or similar polymer material.

Thanks in advance,
BAB

The answer to the lubricant question is moly grease, or molydenum disulfide lubricant. That, from an old hand at repairing and renewing cameras. And which substance I just happen to have more than I'll ever need. Hope that helps someone else who might need to change the lubricant on his 4x5 sliding parts.
