Alignment of valve tappet clearance
1. Dismantle the cylinder cover.
2. Turn the crankshaft until the cylinder in question is in TDC position. The valve push rod must rest on the cam circle.
3. Clean the surfaces, if required.
4. Insert the feeler gauge (P3 = 0.01 mm). See fi gure 1.
5. Fix the torque spanner (P4) on the coupling of the socket wrench (P2).
6. Attach the socket wrench (P2)
7. Attach the socket wrench (P1)
8. Tighten the adjusting screw with P1 until the feeler gauge is fi xed without clearance.
Note ;Check with the feeler gauge that the clearance is between 0.01 and 0.02.
Adjustment of inlet and exhaust valve clearance.
1) Take all safety precaution before ( like take out from standby , close the breaker , close priming pump etc)
1) Clean the surfaces, if required.
2) Insert the feeler gauge (P6), see figure 3.between the inlet rocker arm and inlet valve bridge or between exhaust rocker arm and exhaust valve bridge.
Feeler gauge (P6):
- L16/24: 0.4 mm inlet valve
- L16/24: 0.5 mm exhaust valve
4) loosen the lock nut of the the rocker arm by open end spanner
4) Tighten the adjusting screw with screw driver(P5) until the feeler gauge is fixed without clearance.
6)Now Tighten the nut with spanner and keep the adjusting screw in position by means of the screw driver(P5)
7) check by feeler guage the suction valve clearance as 0.4mm and exhaust valve clearance as 0.5mm.
ON THE 3 location clearance in measured as shown 1 ,2 ,3 in diagram
1-between inlet valve bridge and one inlet valve spindle( for alignment of tappet by filler guage of 0.01mm)
2 -mostly between rocker arm and valve bridge.(by feller guage 0.35 and 0.45 mm ,in between one rocker arm and valve bridge of 2 inlet valve and other in other rocker arm and exhaust valve bridge of 2 exhaust valve)
3- Between rocker arm and push rod(rarely)
Note
The feeler gauge must be clean and inserted as equally as possible between the adjusting screw and the valve bridge. The valve clearance of inlet and exhaust valve is 0.6 mm for a cold engine .
- The spanner must be placed straight on the hexagon lock nut.
- During tightening the feeler gauge must be moved from side to side, however, it must stay between the adjusting screw and the valve spindle. The screw is tightened until a slight squeeze can be felt. The rocker arm must be pressed against the tappet during the adjusting process to remove the clearance.
Risk advice:
- Danger of slipping during adjusting process.
Attention: Risk of hand/finger injury.
- Risk of injury because of sharp-edged feeler
gauge. Attention. Do not put your fingers between adjusting screw and valve spindle.
