Mark the “total horizontal” value on
horizontal side of chart and the “total
vertical” on vertical side of chart.
(13)
Using a straight edge, find the intersection
point of the “total horizontal” and “total
vertical” values. The intersection point
must fall within shaded area for the
flywheel housing concentricity to be within
specification.
(14)
Using the “total horizontal” and “total
vertical” values from the previous example,
the intersection point falls within the
shaded area. Therefor, the flywheel
housing concentricity is within
specification.
(15)
If the intersection point falls outside the
shaded area, the ring dowels must be
removed and the housing repositioned.
NOTE
The ring dowels are not required
to maintain concentricity of the
housing; the clamping force of
the screws holds the housing in
place.
(16)
After the ring dowels (3) are discarded,
install flywheel housing (7) on engine.
NOTE
Reference Step (4) of
“Installation” for installation of
screws.
(17)
To position flywheel housing, tighten eight
screws enough to hold flywheel housing in
place, but loose enough to enable small
movement when struck lightly with a soft
plastic hammer.
(18)
Recheck the concentricity. When
concentricity is within specification, torque
the capscrews to the specified value.
