The maintenance work centered on the breakdown of three-wheeled motorcycles for inspection and removal of hidden dangers is called three-level maintenance. The three-level maintenance is generally performed after 6000-10000 km, and it is best to check at a special service station.

A. Decompose the engine, remove the carbon deposits at the cylinder head, piston crown, piston ring, exhaust port, etc., check the gap between the piston and the cylinder wall, the connecting rod small head bearing and the piston pin, the big head bearing and the crankshaft pin, check The amount of bouncing of the left and right crankshafts, etc.

B. Decompose the clutch, check the free length of the clutch spring and the thickness of the friction plate, replace the spring or friction plate if necessary. Check the transmission gear for cracks, ablation, flaking, and severe step wear.

C. decomposition of the direction of the column combination, clean the direction of the column bearing, add enough grease, after the installation of complex adjustment gap.

D. Disassemble the front shock absorber and check that the free length of the front shock absorber spring meets the requirements and replace the front shock absorber oil.

E. Check the generator, starter brush and commutator wear, if necessary, be replaced.

The inspection and adjustment centered maintenance work is called secondary maintenance. Three-wheeled motorcycles are generally required to carry out secondary maintenance after 3000-6000 km. The contents of the secondary maintenance include the following items in addition to the primary maintenance items:

1. Remove carbon from cylinders, cylinder heads, pistons, piston rings, and mufflers.

2. Check the wear condition of the clutch friction plate and the brake shoe on the brake shoe, and adjust or replace it according to the wear condition.

3, check and adjust the contact gap of the breaker

4. Check whether the axial runout and radial runout of the front and rear rims meet the requirements. If the runoff is too large, adjust or replace them.

5, should check the adjustment valve clearance.

6. Adjust the position of the damper adjustment seat properly.

7. Check the carbon dust between the clean engine, the starter commutator and the commutator segments.

The maintenance of the three-wheeled motorbike is similar to that of the two-wheeled motorbike. When the three-wheeled motorbike runs a certain mileage (generally 1000-2000 km), it should be required to lubricate the parts to be lubricated according to the regulations, and Tighten the exposed bolts and nuts of the car. This kind of lubrication and fastening-centered maintenance work is called a maintenance. The contents of maintenance include the following items in addition to the routine maintenance items:

1. Chain-driven three-wheeled motorcycles should be cleaned by removing the chain; belt-driven three-wheeled motorcycles should be removed for cleaning.

2. Cleaning carburetor, air filter, fuel switch.

3. Remove the carbon deposit on the spark plug, and check and adjust the electrode gap.

4. Check the whole car cable connector contact is good.

5. Check and adjust the free stroke of the clutch grip, throttle handle, brake grip or pedal, and add lubricant to the control cable.

6. Lubricate the speedometer and tachometer shaft with grease.

7. Change the oil.

What is certain is that pure electric vehicles are certainly easier to maintain than fuel vehicles. In addition to some hardware that must be replaced within a certain period of time, it is more important to check the various functional systems of the vehicle.
The first is the inspection of the power system. Like the fuel vehicle, only after inspection can we avoid some hidden dangers. Only in this way can we know where to replace, but the inspection of the electric vehicle may be complicated. It is necessary to check some socket connectors and the insulation protection of the line.

In addition to the power system, the battery as an important part of the electric vehicle is also inspected carefully during the maintenance, and usually in the 4S shop will have professional equipment, you can very accurately check the state of the battery cell.

In other respects, the structure of pure electric vehicles and fuel vehicles is not very different, so components like air-conditioning filters need to be inspected and replaced as appropriate.

Although pure electric vehicles do not have an engine, their batteries and motors are also required to be cooled and cooled by the addition of coolant. In addition to checking the coolant level during maintenance, it is also necessary to conduct freezing tests, especially in the near future. Enter the maintenance before winter.

The inspection and replacement of brake fluid and glass water should also be noted during maintenance. This is also true for pure electric vehicles and for fuel vehicles.

Pure electric vehicles also have gear sets similar to those of fuel vehicles. Therefore, gear oils are also inspected and replaced during maintenance. The gear oil used in pure electric vehicles is similar to that of fuel oil vehicles, but the labels are different.
