Application
Tips: How to restore the preload of hydraulic drawbar force gauge?
- Remove the plug from the B port.
- Loosen the pull rod of Indicator A by one full turn.
- Gently push the Pull Rod A inward to retract the oil level within the oil chamber.
- Fill the system with R68 hydraulic oil via the B port, then reinstall and torque the rear plug.
- Tighten Pull Rod A. The pointer on Pressure Gauge C will subsequently rise.
- Loosen the B plug slightly to allow a small amount of internal oil to seep out, thereby bleeding the system and adjusting the internal pressure.
- Continue this adjustment until the pressure reading stabilizes within the specified range of 10 to 30 kg.
