If equipment struggles to start, stalls under load, or loses pulling power, the gearbox may no longer be transmitting torque efficiently.
Common causes include:
- Worn gears
- Bearing failure
- Internal slippage
- Damaged keys
- Shaft wear
- Broken gear teeth
Ignoring torque loss often leads to complete gearbox failure.
Metal Contamination in Lubricant
Routine oil analysis is one of the most valuable predictive maintenance tools available.
Finding excessive metal particles during an oil change may indicate:
- Bearing deterioration
- Gear tooth wear
- Surface fatigue
- Improper lubrication
- Internal scoring
Rather than waiting for a breakdown, maintenance personnel can schedule repairs before major damage occurs.
Common Causes of Dodge Gearbox Damage
