Group 21
Determining the injection angle
Measuring of permissible variation,
engine block.
(We suggest that Tables 1, 2, and 3 as well as
Calculations 2 and 3 from section"Technical data"
in this book are photocopied.)
51. Install the dial gauge 998 9876 in the measuring
fixture 999 8685 with a preload of 5 mm (0.2").
Zero the dial.
The set value (Le) is 150 mm (5.9") (see figure).
1 = Gauge 999 8685
2 = Depth gauge 999 8685
3 = Dial gauge 998 9876
52. Position the roller tappet, without shims, for the
injector pump in question on the base circle of the
camshaft.
Insert the depth gauge carefully in the injection
pump hole.
NOTE! Make sure that the guide on the roller tappet
ends up in the groove in the material.
53. To do this, turn the crankshaft through 180°
against the direction of rotation, until you are
certain that the roller tappet is placed on the base
circle.
54. Take measurement "L" and enter it in "Calculation
1" in "Technical data".
Depth gauge: 150 mm (5.9")
Dial gauge (X mm): 2.18 mm (0.086")
L = 150 + 2.18 = 152.18 mm
(12.75 + 0.086 = 12.83")
