Adjusting the MPT Series Pump manufacturer tension on an excavator is crucial for ensuring optimal performance and preventing excessive wear.
Here’s a general process to follow:
Tools Needed
Wrench set
Torque wrench
Tension gauge (if applicable)
Safety gloves and goggles
Steps to Adjust Pump Tension
1. Safety First
Ensure the excavator is on a stable and level surface.
Turn off the engine and remove the key.
Engage the parking brake.
2. Locate the Pump Assembly
Open the engine compartment or access panel to locate the hydraulic pump.
Identify the tensioning mechanism, which typically includes bolts and a tensioner.
3. Check Existing Tension
Use a tension gauge to measure the current tension on the pump drive belt.
Refer to the operator’s manual for the recommended tension specifications.
4. Loosen the Tensioning Bolts
Use the appropriate wrench to loosen the bolts that hold the pump in place.
Do not remove the bolts completely; just loosen them enough to adjust the tension.
5. Adjust the Tension
If using a manual tensioner, turn the adjustment screw or lever to increase or decrease tension as needed.
For automatic tensioners, you may need to adjust the mounting position of the pump.
6. Recheck Tension
After adjusting, measure the tension again with the gauge.
Ensure that it falls within the manufacturer’s recommended range.
7. Tighten the Bolts
Once the tension is correct, retighten the tensioning bolts to the specified torque.
Use a torque wrench to ensure proper tightness.
8. Test the System
Start the excavator and let it run for a few minutes.
Listen for any unusual noises and check for proper operation.
9. Final Inspection
After testing, doublecheck the tension and bolts to ensure everything is secure.
Tips
Regularly check pump tension as part of routine maintenance.
Always consult the excavator’s operator manual for specific instructions and specifications.
By following these steps, you can ensure that the pump tension on your excavator is properly adjusted for optimal performance.
