How to use EP code
(420/620)
For exchange of injection pump without any parts of vital importance has been replaced, applies a simplified met-
hod, when there is only the tolerance between the new and old injection pump that is the difference.

T

E
K
=
Value from tabel 3 read with help of EP code from ”
Identification plate”
.
L
O
=
Basic measurement for the injection pumps, 420/620 = 117.5 mm.
A/100 =
Manufacturing tolerance
Example:
On Identification plate there is an EP code value for each cylinder. Read the EP code for actual cylinder and with
help of this value it is possible to read the new
E
K
value with help of table 3.
If read EP code is ”275” that gives
a E
K
value of 120.375 and if the manufacturing tolerance for the new injection
pump is ”63” we will have following equation:
T
S
= 120.375 – (117.5 + 0.63)
T
S
are in this case 2.245 and a control in table 2 gives:
S
S
= 2.3 mm
Thickness on the new shim to be mounted is in this example will be 2.3 mm
