This instuctable is created for the average person; that they can do with household supplies, while more professional tools can be used in place of others at will.

Step 1: Initial Diassembly
They are all the same size, so no marking of the locations of the screws is required.
-Pull the case apart, it should separate easily!
-snake the motor out, the wires will be somewhat stuck and twisted around near the wire outlet hole.
Step 2: Gearbox Disassembly
-PAY ATTENTION on how the red/yellow reduction gears go!! Once you know how they go in your head or drawn on a piece of paper, remove them by sliding them off their shafts.
-Congrats, you now have the motor dissassebled!
Step 3: Gearbox Lubrication and Assembly
-Give ONE drop to each shaft!
-Put one "layer" of reduction gears on and dip your pencil into the Vaseline(petroleum jelly) Dab a little bit on the gears. Not TOO MUCH, just right!!
-put the other "layer" on and daub some more jelly on there.
- Put some jelly on the gear teeth and parts the rotate in the motor case on the forward output gear. Reinstall in case.
- Daub some on the same areas as the front output on the side output gear. Reinstall..
-Reinstall the side output gear so all teeth mesh right!
Step 4: Motor Lubrication and Reinstallation
-Put ONE small drop on the front bearing
-Repeat for rear bearing...
-Carefully push the motor in the mesh of the reduction gears. The motor only goes in one way, its trial and error!
Step 5: Final Assembly and Run-down
-put screws in and softly tighten them down.
Run it back and forth for a few minutes, you wil notice the difference immediately! It will be a long while till you will need to do this procedure again. So now go and put it to use in your K'nex projects in smooth silence!!
