Flexidyne Mechanism Trouble Analysis
Cause
1. Misalignment
2. Bent shaft
3. Excess flow charge

5. Improper installation – Output shaft
jammed against housing
1. Breakdown of flow charge
2. Caked flow charge
3. Below minimum amount of flow
charge
1. Improper installation – Output shaft
jammed against housing
2. Flow charge in bearings – causing
bearing seizure
1. Not enough flow charge
2. Overload
3. Worn flow charge
4. Worn rotor
1. Excessive slip at start up
2. Excessive inching or jogging of
machine
