A. Measure the check dimension at fuiMoad {control stage 4). If there is any deviation from me specified value, fit thinner shim(s) between pressure piece and mushroom There are four shim sizes available which change the distance betwe the pump lever and pump seating face by the following values Oder No 97332. 0.3 thick - 0 75 mm Order No. 9734fi, 0.4 thick - 1 0 mm Order No 97333, 0.5 thick - 1.25 mm Order No. 97334. 0.6 thick - 1.5 mm The limn of adjustment is reached when no more shims can be accor dated
