Re: C drive transmission failure

Roman and Ira,

The rust on all surfaces suggests that there was water on the transmission for a long time. In addition to making sure your lubricant level is OK, it is important to check that it does not look milky. Wearing of the third shaft seal near the propeller when the seals are oriented the “Amel way” causes water intake that mixes with the oil because the other two other seals are oriented to prevent oil loss but they allow water intake. If the seals are not replaced, and when the transmission is not used frequently, over time the water settles down and causes the corrosion of all surfaces visible on your pictures.

One good reason to keep an eye on the color of the lubricant, replacing the seals and thinking about seal orientation.
