Lubrication for Open Transmissions

[sanddrag]

It can be rather difficult to contain sometimes on the higher-speed stages near the motors. You want something with a bit of 'stick' to it so it doesn't just all fling off. Most teams use a thin coat of white lithium or moly grease, which seems to work fine. I've also heard of different teams using teflon-based lubricants. I don't have any real specific recommendation. I generally use whatever we have on the shelf at the moment and haven't had a real problem yet, with the exception of AndyMark 12-tooth CIM pinions wearing out.

Of course, there's the whole other school of thought that says any sort of 'wet' lubrication at all in an open gearbox will attract dirt and cause more wear.
