Hold a torque of 60 to 70 N·m (45 to 50 lb. ft.)
on adapter (11) in a clockwise direction, and
tighten bolt (6) that holds the timing gear to
270 ± 30 N·m (200 ± 20 lb. ft.).
Remove the timing bolt from the flywheel and
timing pin (4) from the fuel pump camshaft.
Rotate the crankshaft counterclockwise two
revolutions. If the timing bolt can be installed
in the flywheel and the timing pin can be in-
stalled in the fuel pump camshaft, the timing
is correct.
If either the timing pin or the timing bolt can
not be installed, do Steps 8 through 16 again.
Checking Engine Timing With 6V3100 Diesel
Engine Timing Indicator Group (Models

Loosen all fuel line clamps that hold No. 1 fuel
injection line and disconnect fuel injection line
(8) for No. 1 cylinder at the fuel injection pump.
Slide the nut up and out of the way. Put 5P7436
Adapter (7) in its place and turn adapter (7)
onto the fuel pump bonnet until the top of the
bonnet threads are approximately even with the
bottom of the “window” in the adapter.
Put the 5P7435 Tee Adapter (6) on the Injection
transducer (4) and put the end of the 5P7435
Tee Adapter (6) in the “window” of the 5P7436
Adapter (7).
Put fuel injection line (8) on top of 5P7435 Tee
Adapter (6). Install 5P7437 Adapter (5) and
tighten to 40 N·m (30 lb. ft.).
Remove plug from the flywheel housing. Install
pipe adapter (3) into hole plug was removed
from. Tighten only a small amount.
Push the TDC magnetic transducer (2) into the
pipe adapter (3) until it makes contact with the
flywheel. Pull it back out 1.6 mm (.06 in.) and
lightly tighten the knurled locknut.
Connect the cables from the transducers to the
Engine Timing Indicator. Make a calibration
check of the indicator. For calibration proce-
dure, make reference to Special Instruction
Form No. SEHS7742.
Start the engine. Get the engine to operating
temperature. With the engine at low idle, check
engine timing. Increase engine speed and check
timing at 2300 rpm.
