Leica III CLA – modern lubricant substitutes?
I'm preparing to CLA a Leica IIIb and found this older thread where someone was trying to identify modern replacements for the original Leica lubricants https://www.reddit.com/r/AnalogRepair/comments/y38g2d/leica_cla_grease_and_lubricants
After checking service manuals, forums, and current datasheets, this is my current shortlist:
#300 → Molykote EM-30L / Losimol 6305 Heavier grease for slow-moving/sliding parts such as sleeves, locks, and other low-speed mechanisms.
#460 → Molykote EM-30L Medium/light precision grease for shafts, bushings, and moderately moving parts.
#601 → Moebius 9010 Fine watch oil for low-torque pivots and the slow-speed escapement.
#602 → Klüber ISOFLEX PDB 38 CX 1000 Very light fluid grease for high-speed bearings and curtain roller shafts, where very low running torque is required.
#618 → Molykote 33 Light Light grease for curtain roller springs and other low-load, spring-driven mechanisms.
#704 → Klüber ISOFLEX NBU 15 Load-bearing precision grease for shutter winding gears, gear teeth, cams, and sliding contacts.
The main areas I want to lubricate are the shutter winding gears and shafts, curtain roller shafts/springs, and the slow-speed escapement.
Does this selection look reasonable? I'd especially appreciate feedback from anyone who has actually serviced Barnack Leicas, and whether any of these lubricants can safely cover more than one of the original Leica references.
