Disassembly
To carry out repairs, it will be necessary to disassemble the Lifan motor of 15 l. from." or its analogues. The principle of operation is approximately identical. The operation consists in observing the following steps:
- Oil from the crankcase and gearbox drains, as does the remaining fuel from the gas tank.
- Dismantle the fuel tank, muffler and atmospheric filter.
- Disconnect the carburetor, which is attached to the cylinder head with a pair of studs.
- Remove the manual starter and fan cowl.
- The flywheel is fixed with an improvised tool so as not to damage the propeller blades.
- Unscrew the fixing nut.
- Using a universal puller, compress the flywheel from the landing cone.
- Check the keyway for deformation.
- Dismantle the ignition coil and the lighting coil.
- Unscrew the fixing bolts of the cover and head.
- Remove the cylinder head.
- The valve tightness is checked by filling the combustion chamber with kerosene in an inverted state.
- If within a minute the liquid does not appear in any of the valves, their isolation can be considered satisfactory. Otherwise, the problematic parts should be rubbed using abrasive paste or replaced.
- On versions equipped with a gearbox, its cover is removed, the secondary shaft is removed, the gear or sprocket is pressed from the crankshaft. Excessed tooth elements should be replaced.
- Unscrew the bolts of the rear cover, after which it is removed. Next, the camshaft is removed from the crankcase.
- In the free space, bolts connecting and connecting the lower cover of the connecting rod with its body are found and unscrewed; the cover and crankshaft are removed.
- The piston is pushed into the crankcase with the connecting rod.
After repair and replacement of defects of the Lifan 15 motor, the assembly is carried out in the reverse order.
