Measuring of permissible variation, roller
tappet and camshaft.
55. Zero the dial gauge.
56. Read the injection angle, Fb
identification plate.
Read pre-stroke, Vh
"Technical data".
Enter both values in calculations 2.1 and 3.1 in
"Technical data".
Example:
Fb = injection angle = 6.0°
nom
Camshaft = A
Vh = pre-stroke = 6.11
nom
57. Turn the crankshaft in the direction of engine rota-
tion until the dial gauge shows (-) Vh
Example:
7-6,11 = 0,89
The dial gauge was zeroed at 7 mm pre-stroke
and when it shows 0.89 in the example, you have
reached Vh .
nom
58. You can now, on the protractor, read the value
(eg. 354,5°) for when the injection valve should
have opened.
Example: 360 - 354.5 = 5.5
Enter it into calculations 2.1 and 3.1 in "Technical
data".
Example: F = 5.5°
B akt
59. Read off demension "A" = the code for the injec-
tion pump length and enter it into "Calculation 2.1"
in "Technical data".
Example: A/100 = 0.63 mm (0.025")
