My transmission is leaking air when vacuum is applied to the system. What could cause this and how do I fix it?

The transmission is the metal cylinder on top of the wiper basket and creates a vacuum-tight seal between the rotor of the wiper and the rest of the system.

It is composed of two bearings and a few gaskets.

The bearings should be lubricated every 4-6 months with 0.5mL of white oil. If crude oil contains sulfur (usually from using sulfur burners in the grow to prevent powdery mildew) this sulfur can cause rapid degradation of both the gaskets and bearings in the transmission.

While the transmission can be easily rebuilt by following SOP- Transmission Fix, it is not recommended to process crude oil that contains sulfur.
