1 A) OLD STYLE BALANCE GEAR ASSEMBLY -
WITH A BALANCE GEAR TIMING TOOL
1 . Align the primary timing marks of balance
gears with the teeth on timing tool. Insert tool
so it meshes with gears. Hold or clamp tool
against oil pan gasket surface. Refer to Figure
12-13.
Figure 12-13. Installing Balance Gear
TimingTool.
2. Lubricate the crankshaft rear bearing surface.
Insert the PTO end of crankshaft through rear
bearing. "Straddle" the primary and secondary
timing marks on crankshaft over the rear bear-
ing oil drain (refer to Figure 12-14). Press the
crankshaft into rear bearing until the crankgear
is just above the camshaft gear but not in
mesh with it.

Balance Gears.
NOTE: If the crankshaft and bearing plate have not
been separated, position the fuel line and wiring
harness between the bearing plate and crankcase
before pressing the crankshaft all the way in.
3. Remove the balance gear timing tool and
align the primary timing mark on the crank-
shaft with the timing mark on the camshaft
gear. Refer to Figure 12-15. Press the crank-
shaft all the way into the rear bearing. Make
sure the camshaft and crankshaft gears mesh
and that the timing marks align while press-
ing.
Figure 12-15. Aligning Crankshaft And
Camshaft Timing Marks.
4. Check the timing of the crankshaft, camshaft,
and balance gears:
• The primary timing mark on crankshaft
should align with the secondary timing mark
on lower balance gear. Refer to Figure
12-16.
Figure 12-16. Checking Crankshaft And
Balance Gear Alignment.
• The primary timing mark on crankshaft
should align with the timing mark on cam-
shaft. Refer to Figure 1 2-15.
If the marks do not align, the timing is incorrect
and must be corrected.
