COATS M-61 Wheel Balancer User Manual

Instructions

1. Assemble the M-61 wheel balancer as

shown in ﬁgure A.

2. After assembling the wheel balancer,

view the circular level (bubble) at the top of the bead. See arrow 1, ﬁgure B. Make certain

the bubble rests in the middle of the black circle before using the balaner.

Adjustments are made while the head rests on the support shaft (X-065). The bubble on the M-61 wheel balancer is mounted onto the top of the head assembly cone by three (3) adjusting screws. Take care to make certain that the bubble rests squarely in the center of the black circle.

3. Remove the tire and wheel from the vehicle. Clean off any debris from the inside/underside of the rim. Check the hub hole on the rim to insure that it is clean to allow for uniform seating on the balancer cone (head assy.).

Place the tire/wheel assembly on the balancer. Listen for uniform seating when tire/wheel assy. engages cone. Let the tire/wheel settle to a stop.

There exists an out-of-balance condition when the heavy side of the tire/wheel causes the bubble to move outside the black circle in the opposite direction from the heavy side. See arrow 1, ﬁgure B.

Place a weight on the light side of the rim closest to the bubble. See arrow 2, ﬁgure B. If the ﬁrst weight does not bring the bubble back to the middle of the black circle, then try a larger (heavier) weight , or a smaller (lighter) weight to bring the bubble into the middle of the circle as shown in arrow 1, ﬁgure C.

4. Remove the tire/wheel from the balancer and place the proper amount of weight needed equally on both sides of the wheel, attach 1 1/2 ounce weight on the top of the wheel rim and 1 1/2 ounce weight on the underside of the wheel rim at the same location.
