VALVE GEAR

Valve clearances

(fig. 26)
The clearance between rocker arms and valves should be checked and adjusted after the
first 500÷1,500 km and every 5,000 thereafter or if the valve gear becomes excessively
noisy.
Adjustment should be carried out with the engine cold and the piston at TDC in the
compressions phase (valves closed).
Remove the rocker box cover and proceed as follows:
1 loosen nut «A».
2 turn the adjuster screw «B» to obtain the clearances:
intake valve 0.10 mm;
exhaust valve 0.15 mm.
Use a suitable feeler gauge «C» to measure the clearances.
Remember that if the clearances are greater than those specified, valve gear will be noisy;
if the valves donor close fully this can cause problems such as:
loss of compression;
engine overheating;
valve burn-out, etc.
