MP10 Do I Need to Replace Bearing?

[timqmana]

I bought a used MP-10 (quiet drive, mobius, all the latest stuff) and I run it on short pulse at 50% and the dry side feels kind of hot. Is that normal at that speed or should I look into replacing the bearings.

Do you lubricate it? Molykote works great

Typically bearing failures make noise. If yours is quite I think your good. All my vortechs (I have 8) get warm. I haven't really paid attention to what mode causes the most heat. I've heard of lubricating the wet side but I have never lubed any if mine.
