Re: R-9 Overdrive

I've observed over the years that internal lubrication was a weak spot on the R9s. There are a number of small holes that are supposed to channel lube to various critical spots and they seem to get plugged with old gear oil goo. Those planetaries run on uncaged needle bearings and if they run dry they will eat clean through their little axles.

Of course, this is made worse by cold weather, and worse yet if the gear oil has thickened with time. I'm starting to wonder if when getting a car out of a long sleep if it would not be a good idea to fill the overdrive with some 10 weight (ie, ATF) and let it run on jackstands for a while.
