Propeller Shaft Balance Weights

When using clamps in order to balance a propeller shaft with the total weight method, the correction weight required will often be a fraction or a multiple of one hose clamp. Use the following phasing procedure with 2 hose clamps in order to accurately place any required amount 0 - 2 weights (0.0 - 2.0 total weights).




1. Ensure that the clamps are located with even spaces on either side of the light spot, or 180 degrees opposite the heavy spot.
The table containing the weight amounts in terms of the total weight and the included angle (spread) between the clamps is in specifications.
2. If the vibration does not change at all or gets worse, then 1 clamp is too light or too heavy. Repeat the procedure using the 2 clamps together.
3. If the previous step did not correct the problem, repeat the procedure using the 2 clamps separated in order to reduce the spinning weight.
4. Continue the trial and error procedure using different weights in different locations until you achieve the best balance.
5. If more than 3 clamps aligned in the same position are required, replace the propeller shaft.
6. If you are able to reduce the vibration in the stall, but are unable to eliminate the vibration completely, road test the vehicle. A slight vibration noticeable in the stall may not be noticeable on the road.
