    i just spray motor cleaner into the can and let the fluid drain out carrying the dirt, dust....

    then put a drop of oil on the ends

    I don't know. I sprayed mine out with aerosol electronics cleaner and put triflow on the ends and mine lasted like 2 months a piece.

    RC electric motor cleaner. Spray until liquid coming out of motor is clean. Let evaporate or blow dry with compressed air. Lube bushings on both ends of the can with 3in1 oil or similar light weight oil.

    You need to be careful using contact cleaner, some aren't good for plastic...I don't get why as plastic is a great insulator and used in a lot of electronics...but such is life. Read the label.

    FM, lack of lube and heat are the biggest enemies of a brushed motor.

    Eh, i dont think lack of lube is an issue with the 775. I see alot of them fail at the brushes/commutator, which doesnt require lube.

    A lack of lube certainly wouldn't help matters. The 775 may have brush and commutator shortcomings that cause failure before the bushings, however, lubed bushings are more efficient than dry.

    The more efficiently your motor spins the less current required to turn it at any given speed. Wich leads to less strain and heat...heat that could damage a comm or brushes.

    Buuuut over lubricating isn't good either. It can attract excess dirt and debris wich could also cause premature failure of brushes and comm...you need to find a happy medium.

    Motor cleaner will remove any lubrication it comes in contact with. After cleaning lube is a must...just don't go crazy.

    I was told my a electric motor shop, that the oil impregnated bushings don't require lube. I think the 775 prob has a problem with heat. I'll bet a heatsink would extend the life of them.
