FAQ:
What to do if the hydraulic system pressure is low?

Check the hydraulic pump, pressure control valve, and hydraulic cylinders. Test the hydraulic oil for contamination or degradation, clean or replace relevant components, and ensure the hydraulic system is properly sealed.

The travel oil motor has just been repaired. The track moves faster at low throttle, but will not move at high throttle. What is the remedy?

This is because the valve plate was over-ground during maintenance and the grinding amount was too much, so the pressure between the valve plate and the cylinder plane is insufficient. At low throttle, the oil pressure is small, and it is not easy to leak between planes; at high throttle, the oil pressure increases, and overflow occurs between planes, causing the track to be unable to move at high throttle. The remedy is to add a gasket to the spring. If it is a butterfly spring, you can add an extra butterfly spring.

How do you know if the perpendicularity between the ground gear plane and the bearing hole has changed?

It can only be found when assembling the gear pump, because the end face clearance is very small, generally around 0.05mm. If the perpendicularity between the end face and the bearing hole has changed, the gear shaft cannot move after the pump is assembled. If the locking screw is loosened a little, but it still does not turn smoothly, and the gear pump is disassembled and inspected, there are scratches on the end face. This is caused by the end face plane not being perpendicular to the bearing hole.

How to charge a new battery for the first time?

After the newly purchased battery is injected with the liquid with the appropriate specific gravity, it should be placed for 6-8 hours to allow the liquid to penetrate the plates. When the temperature of the liquid drops below 30℃, it can be charged for the first time. The initial charge should be carried out in two stages. The charging current in the first stage should be lower than 1/10 (one tenth) of the rated capacity of the battery, and the time is about 25-35 hours. When the voltage of a single cell rises to 2.4 volts, the current is reduced by half and the second stage is entered, which takes about 20-30 hours. When the electrolyte emits strong bubbles and the specific gravity no longer rises, the voltage of a single cell rises to 2.6-2.75 volts and remains unchanged for 2-3 hours, it means that the battery is fully charged. During charging, the temperature of the electrolyte will rise, exceeding 40℃ in summer and 35℃ in winter. Charging should be suspended and recharged when the temperature drops below 30℃ to prevent damage to the plates and separators.
