6. Check through the inspection window that the
pointer is aligned with reference marks 4_ for
mod. TD60D, 0_ for mod. TD70D and TD95D, or
1_ for mod. TD80D and TD90D.
7. With the injection pump in its seat, remove the
plug (1) on the pump cover.
8. Fit dial gauge 380000228 (1) fig. 251 and the as-
sociated tool 380000229 (2), pre−loading the
shaft by approximately 2.5 mm (0.0984 in.).
9. Turn the flywheel slowly backwards, so as to
bring the plunger to B.D.C. at the start of the deli-
very stroke (the point at which the dial gauge ne-
edle stops falling).
10. Zero−set the dial gauge and slowly turn the
flywheel clockwise (as viewed from the fan end
of the engine) until the pointer lines up with
reference marks 4_ for TD60D models, 0_ for
TD70D and TD95D models, or 1_
and TD90D models.
11. Check on the dial gauge that the plunger has
completed a stroke of 1 mm (0.0394 in.) up to this
point, if not, slacken off the pump mounting bolts.
If the plunger stroke is checked with the pointer
at the T.D.C. there must be a stroke of: 1.47 mm
(0.0578 in.) for mod. TD60D or 1.00 mm (0.0394
in.) for mod. TD70D and TD95D, or 1.12 mm
(0.0440 in.) for mod. TD80D and TD90D.
12. Turn the pump anti−clockwise if the plunger has
completed a shorter stroke and clockwise if the
stroke is longer, repeating the test until the cor-
rect stroke is obtained.
13. Having obtained the correct plunger stroke, fix
the pump in position by tightening the mounting
nuts to the torque specified on page 24.
14. Remove the dial gauge 380000228 (1) and relati-
ve tool 380000229 (2) and replace the plug and
tighten to a torque of 8 − 10 Nm (5.9005 − 7.3756
ft lb).
15. Disconnect the KSB external power supply unit.
16. Refit other parts in the reverse of the dismantling
order.
