Check, by means of a feeler gauge, that the valve clearance is
0,10÷0,15 mm (0.004÷0.006 in.) for INTAKE and 0,15÷0,20
mm (0.006÷0.008 in.) for EXHAUST;
Otherwise, lift the retaining clip (7) using a hook, let the rock-
er arm slide to one side, extract the pad with a pair of pliers
and check the thickness;
Depending on the result, fit a new pad (as spare parts, pads
are supplied ranging from 1.60 mm to 2.60 mm in steps of
0.05 mm) and return the clip and rocker arm;
Check the valve clearance again and, if it's correct, reassembly
the removed parts using the reverse procedure.
