Lubrication of R3 & R4 Motors

Lubication of all bearing parts are necessary for best life and performance. Brushless motors require the same care.
Both the R3 and R4 motors are easily lubricated and metal bearings should be lubed every four race weekends or so. Ceramic bearings should be lubricated twice as often.
In the pictures attached you will see how to do this on all R3 and R4 motors:
1. Record the advance of the motor (the bright arrow pointing at 30). Just remember the number under the pointer as this is the timing set for this particular motor.

(1) Loosen and remove the three black screws (see above). The screws require a 1.5mm hex wrench. Gently pry off the orange cover with your finger nail. Using a very light machine oil (or Power Products motor lube: coming soon!) in a small tip dispensing bottle, apply 1/2 drop as shown below.

Pic 3: Put the orange cover back on the motor, and install/tighten the three black screws AFTER you put the pointer back to to same number (see first picture above). These screws should be firmly tightened by hand.
Apply a 1/2 drop on the other end of the motor and you are done!
