We all have our opinions but consider using only newer synthetic grease.? For mechanical PTO and VFO rebuilds, I¡¯m using Mobile1 and Valvoline SynPower brands.? Petroleum axle and lithium-based grease has a short lubrication lifetime.
Likewise, I strongly suggest staying away from pure silicone and Teflon-based grease like TriFlow.? I nearly ruined a Drake 1A VFO gearbox after a rebuild with TriFlow. Teflon and silicone lose its ability to lubricate in conditions of angular pressure.? After spending a day removing the TriFlow grease, the assembly was re-packed with Mobile1 (Red) synthetic grease and the assembly moves as smoothly today as it did after the rebuild ten years ago.
