STEP 4-2 TAIL PINION GEAR MESH
IMPORTANT about GEAR MESH:
In order to archive smooth operation of the main drive train, it is important that the correct gearmesh is obtained after assembly.
Try to mesh the gears to get the minimum amount of backlash and the smoothest rotation. Remember that too little clearence
and the train will be too stiff to work properly and too much clearance may result the teeth stripping off when under load.
Step by Step to get a correct Gear Mesh:
Starting with the tail gear and tail pinion gear.
Cut from a normal piece of printing paper a slice aprox. 15cm long and 5mm high and pass it between both gears.
Turn the main train to ensure that the paper runs through the gears and optain a correct mesh.
Now press the Tail Drive Pinion Gear Assembly (STEP 1-2) firmly against the main train and secure the eight
M3x10 Socket Head Bolts with threadlock.After finishing the gear mesh don´t forget to take out the paper
between the gears.
