*First choice - Gas Metal Arc Welding Process:
Butt joints - apply two layers (passes) of weld metal.
First pass should only fill approximately
1¤2the thick-
ness. Vertical position welds - maintain electrode
wire at leading edge of weld puddle while traveling
down hill to produce maximum penetration into the
sleeve. These techniques work for FCAW as well.
**E7018new electrodes may be exposed to the
atmosphere for up to ten hours with no harmful
effect. Reconditioning schedules should come from
the manufacturer.

SPECIFICATIONS - FRAME DIMENSIONS
NOTE: Frame dimensions are listed in metric scale.
All dimensions are from center to center of Princi-
pal Locating Point (PLP), or from center to center of
PLP and fastener location.
VEHICLE PREPARATION
Position the vehicle on a level work surface. Using
screw or bottle jacks, adjust the vehicle PLP heights
to the specified dimension above a level work surface.
Vertical dimensions can be taken from the work sur-
face to the locations indicated were applicable.
