Align hole A in rod 105097 with hole in top latch as shown at right & tap the 13/16" long pin
into latch hole.
3b.
Measure
DIM B
as shown below.
3c.
Use chart to determine pinning location of rods 105097 & 104172-2.
Round
DIM B
to nearest value in chart. If more than 3/4" different from one of
these chart values, drill a .189 (#12 drill bit) diameter hole halfway between
the 2 holes nearest to the measured
DIM B
and use this hole
as pinning hole in next step.
3d.
Insert 104172-2 rod into 105097 rod & line up
appropriate pinning holes (from chart) on both rods
and tap in the 1/2" long pin to secure.
3e.
Calculate
DIM D
:
(
DIM D =
measured
DIM B
minus 15 7/8")
Thread the assembled rods/latch into the centerlift
mechanism assembly as shown at right until
DIM D
is achieved (within 1/16").
