12. If the fuel does not increase, it is exhaust time.
Therefore, turn the crankshaft 360° and repeat
the procedures above to find the compression
time.
13. Mark the injection timing measured from the
timing window and measure the interval
between your mark and "1, 4 AZ'. Note this
measurement; it will be used when calculating
the shim for adjustment of pump timing.
Taking the positions of two points on the flywheel
housing into consideration, if the line on the
flywheel seen on the window during the observed
injection time is; (see "Figure 70")
I. in alignment, it means the ignition advance is
in factory settings; no adjustment is required.
II. above the level, it means the advance is
insufficient, delay is required.
III. under the level, it means the advance is
excessive; it requires to be put forward.
To adjust injection timing, it is required to
add/remove shims, the parts (1) shown in "Figure
71", under the pump.
To delay injection timing (increase ignition timing,
e.g. from 10° to 12°), reduce shims.
To put injection timing forward (reduce ignition
timing, e.g. from 14° to 12°), increase shims.
At the 9” flywheel option, every 2.4mm is equal to
1°.
At the 11” flywheel option, every 2.9mm is equal
to 1°.
To delay injection timing to 1°, add 0.1mm shim
under the pump.
To put injection timing 1° forward, remove 0.1mm
shims under the pump.
To identify the flywheel type, use the overall
dimensions (A) of the flywheel housing shown in
“Figure 72”.
This is 390 mm for tractor with 9” flywheel.
This is 436 mm for tractor with 11” flywheel.
