MEASURING THE PITCH OF A WHEEL BALANCER SHAFT


Count * the number of threads over 4 cm (40mm)

13 threads = 3.0 mm pitch thread
12 threads = 3.5 mm pitch thread
10 threads = 4,0 mm pitch thread
 9 threads = 8,46 mm pitch thread

* count the troughs (lowest point) not the peaks of the thread.

CORRECT USE OF THE HAWEKA PRO GRIP QUICK RELEASE WING NUT

A prior condition for the correct functioning of the quick release wing nut is a clean thread, both on the wing nut and on the actual threaded shaft. Dirt prevents the thread from engaging properly and the Wing Nut will not hold or lock. This may result in the wing nut coming loose when the machine is started!
Use dry lubricants only, never use oil! Wet lubricants help to create a paste which acts like a grinding paste.

Correct mounting procedure for HAWEKA PRO GRIP Quick Release Wing Nut.

Pull the lever back fully and slide the quick release wing nut over the threaded shaft until the quick release wing nut is against the wheel or adaptor. Release the lever and turn the wing nut back a quarter of a turn until the wing nut has engaged the thread. This will ensure that the thread of the wing nut does not sit (or ride) on the top of the thread of the shaft. Tighten the wing nut firmly by pulling the wing nut upwards (from 6 o'clock to 9 o'clock), your left hand holding the wheel firmly. This allows for a better tightening action.

Wheel balancers with very hard braking or starting action it is important to firmly tighten the wing nut.
Do not use a hammer.

• To undo the wing nut
IMPORTANT - FIRSTLY LOOSEN THE WING NUT BY TURNING IT BACK HALF A TURN AND THEN PULL THE LEVER TO ACTIVATE THE QUICK RELEASE MECHANISM.

Do not activate the quick release mechanism without backing off the wing nut as continual operation in this manner will result in premature wear of the wing nut, which will cause the wing nut to slip when it is tightened.
