7.20 Adjusting the valve clearance at Kubota 02 series
NOTE:Representative procedure The described procedure is representative for Fischer Panda
generators. The original location of the item must be taken
from the generator description of this manual. All
replacements and repairs should be done by a trained
person.
Tools:
• Wrench for valve cover: W.A.F. of 10 mm
• Spanner for counter nut: W.A.F. of 11 mm
• Flat screwdriver for adjusting screw
• Feeler gauge
1. Unscrew valve cover.
2. Rotate crankshaft until the valve to be adjusted is fully open. If necessary, rotate back and forth to determine the
dead centre. See Fig. 7.20-1, “Valve open,” on page 129.
3. Rotate crankshaft 360°. The valve is then closed, as the cam shaft was rotated 180°. See Fig. 7.20-2, “Valve
closed,” on page 129.
4. Check the valve clearance with a feeler gauge! If the engine is cold, the valve clearance must be between
0.145mm and 0.185mm. The feeler gauge must slide between rocker arm and valve stem with light suction.
Adjust the valve clearance as necessary using the screw on the rocker arm. Loosen the counter nut first. After
adjusting, the counter nut must be retightened. Check the valve clearance again.
5. Perform the same procedure with the other valves.
6. Refit the valve cover and firmly tighten the screws.
NOTE: Mark the valves that were already checked!
