Default Scorpion Rebuild - 1000 series serial number

Ok, so I finally determined that I have a shaft seal leak on my 1000 series scorpion. See this thread for diagnosis/conclusion: http://www.biofuelstechnologies.com/...ead.php?t=5022

I've got about 100 hours logged on this motor with the shaft seal leaking.


Now I'm following the rebuild instructions and am pretty concerned with what has happened. The oring between the pump head and the motor(can be seen page 4 of rebuild manual) has disintegrated. There is oil at the bottom of the motor where the power enters from the plug, luckily it seems as if the windings are 99% clean, except on the very bottom where the power enters. My next course of action is to buy some electric motor cleaner and clean all the electrics with this. Then reassemble like the rebuild instructions show.

What do you all think of that course of action? Input appreciated!

Cleaning is definitely needed.
It is critical that you get the crud off the inside of the brush holders and the outside of the brushes, the brushes must move freely in the holders.
I would not recommend things like Purple Power or the Zep Cleaners. They do work very well to dissolve the oil/poly but I think they could damage the windings etc, particularly the brass and copper components.
I would soak the parts in brake cleaner or another solvent for as long as it takes to dissolve the crud.
It would be a good time to replace the bearings as well.
