Hi Mike,

I talked to Sean Plummer of Hacker USA today. The grease is only available in bulk quantities, but what he said they would do is pretty good. If you are a Hacker customer with a C50 geared motor, call Hacker USA and they will send you a quantity of the grease suitable for several lubrications for free.

The grease they used before this is called Superlube. He mentioned that it is available in smaller tubes from industrial supply houses. It is in a metallic silver tube. Sorry, I don't have an outlet for this grease. I think the best solution is to call Hacker USA and get the free stuff!

The next time I need a gearbox lube job I will take pics and post the process. It's pretty simple but does require some easy obtained tools like strap wrenches. And there are some things to watch in disassembly and re-assembly. It might be a couple of weeks before the motor in the Partner I'm flying needs the job, but I'll do it then.

Hope this helps!
