Hi all, Limbach Tech Bull 18 calls for lubricating the magneto impulse couplings with adhesive oil every 25 hours through the accessory case port. That TB calls for Molykote (a Dow Corning product, spelled Molikote in the TB. Maintenance Instruction 28 later says that due to availability problems with Molykote,
Dow Corning:C 40 (liquid) or - Bremer & Leguil: RIVOLTA SKD 170 (Spray-on) can be used instead. The only US supplier I can find for Dow C40 wants to sell me a kg for $50! And I only need 10 drops (for this lube cycle anyways). What have you all been using, if anything? I think I read somewhere else that no lube is necessary for this type of coupling.... The MI also says "such lubricants [as recommended above] are used for motorcycle drive chains", but I hesitate to use a petroleum-based product instead of graphite-based like the C40 (high temperature)...? The impulse coupling spring also needs to be lubed, but motor oil is the recommended lubricant for that (by magneto rebuilders). Cheers, Tom
