(7) Remove the front cab mount bolt to the Front
End Sheet Metal (FESM) bracket. (Fig. 5)
(8) Make a vertical mark on the inside and outside
face of the frame rail 112 mm (4.5 in.) from the for-
ward edge of the PLP hole in the sides of the rail.
(Fig. 7)
(9) Using a straightedge, connect the two lines on
the top and bottom of the rail.
(10) Using the service tip as a guide, re-check your
cut lines to ensure the service tip will fit when the
cut is made.
CAUTION: Do not use any flame or plasma cutting
equipment to cut the frame in this procedure. This
is due to the inaccurate nature of the cut-line and
the fact that the high temperatures achieved duringflame or plasma cutting will change the metal char-
acteristics and may weaken the frame and/or repair
location.
(11) Using a reciprocating saw or equivalent, care-
fully cut and remove the damaged frame rail tip.
(Fig. 6)
(12) Assemble the service sleeve. Refer to SER-
VICE SLEEVE ASSEMBLY at the end of this proce-
dure.
NOTE: Any burned surface coatings will need to be
removed from the sleeve prior to installation and
application of corrosion preventative coatings.
(13) Smooth and square the cut edges of the origi-
nal frame. (Fig. 6)

(14) Dress the cut edge of the existing frame in
preparation for the new rail tip.
(a) Drill four 13 mm (0.5 in.) diameter holes in
the new tip and four more in the existing frame to
accommodate ring-fillet welds. Center these holes
19 mm (0.75 in.) from the cut face of the rail and
38 mm (1.5 in.) from the top and bottom of the rail.
(Fig. 7)
(b) Bevel the edges of the new tip, existing
frame, and ring-fillet holes 25É - 30É. Scribing a
line 2 mm from the cut edge and then grinding
back to the mark will simplify the bevel creation
process and accuracy. (Fig. 8)
(c) Remove any burrs at the holes and beveled
edges.
(15) Dry fit the new rail to ensure alignment and
fit and make any adjustments as necessary.(16) Remove all internal and external OEM e-coat
within 51 mm (2.0 in.) of the weld joint on the
replacement tip and the existing frame rail.
NOTE: Any burned surface coatings will need to be
removed prior to application of corrosion preventa-
tive coatings.
CAUTION: Shield the surrounding area and compo-
nents from exposure to the welding spatter and
heat.

date the sway bar mounting bolt. (Fig. 11)
(18) Slide the service sleeve into the replacement
frame tip and align to the 2 mm (0.08 in.) off center
line made previously during the sleeve assembly and
tack the ring fillet welds to hold them in place. (Fig.

holes on the replacement frame tip (Fig. 13). (Refer
to 13 - FRAME & BUMPERS/FRAME - SPECIFICA-
TIONS - WELDING)
(21) Install the upper FESM insulator onto the
replacement tip and position the service sleeve/re-
placement tip into the existing frame rail.
(22) Loosely install the lower FESM insulator and
cab mounting bolt.
(23) Using the appropriate measuring equipment,
verify the front end sheet metal bracket's location in
all three (X,Y, and Z) planes of space, and adjust if
required. (Fig. 14)
CAUTION: Shield the surrounding area and compo-
nents from exposure to the welding spatter and
heat.(24) When correctly fitted and a weld root gap of 4
mm minimum to 6 mm maximum (0.16 in - 0.24 in)
is established, tack the ring fillet welds to hold the
tip in position, then complete the ring fillet welds.
NOTE: Ring-fillet welds may be filled in with weld
material if an improved cosmetic appearance is
desired.

(25) Confirm alignment of the replacement frame
rail tip. (Fig. 14)
(26) Final welding should be performed in a skip
(stitch) type method to minimize the heat buildup
and frame distortion, utilizing the Weld Process
Specifications at the end of this section. The pre-
ferred method is GMAW (MIG). (Refer to 13 -
FRAME & BUMPERS/FRAME - SPECIFICATIONS -
WELDING)
(a) Apply root pass welds to the root joint one
quadrant at a time, switching to the opposite side
of the frame for each quadrant. (Fig. 8)

rities before proceeding with the cover pass welds.
(c) Apply the cover pass welds in the same man-
ner as described above.

rail tip. (Fig. 14)
NOTE: Any burned surface coatings will need to be
removed prior to application of corrosion preventa-
tive coatings.
(28) Dress the welded area and apply corrosion
resistant coatings inside and out.
(a) Apply etch-primer to the inside of the frame
rail repair area.

space between the original frame rail and the rein-
forcing sleeve.

SERVICE SLEEVE ASSEMBLY
NOTE: Two sleeve halves are included with each
kit. Modifications as follow, are necessary to create
the correct sleeve assembly for each application.
(1) On 4X2 models, the9lower9sleeve is made by
cutting off the tab and cutting out a notch in the bot-
tom sleeve portion. Round the corners of the cut out
to keep stress cracks from forming. On 4X4 models
the9lower9sleeve is used as provided. (Fig. 15)
(2) On both 4X2 and 4X4 models cut off the front
tab on the upper sleeve portion. (Fig. 16)(3) The sleeve halves are shipped slightly over-
sized to allow custom fitting to each replacement
frame rail tip. It is necessary to grind the mating
surfaces to achieve the desired snug fit into the
replacement tip (rail tube has increasing height rear-
ward of the cut line). Once the two sleeve halves are
fitted, bevel the edges 25É - 30É.
NOTE: Scribing a line 2 mm from the cut edge and
then grinding back to the mark will simplify the
bevel creation process and accuracy.
(4) Remove any burrs at the beveled edges.
(5) Using the Weld Process Specifications table
(Refer to 13 - FRAME & BUMPERS/FRAME - SPEC-
IFICATIONS - WELDING), weld the two halves of
the repair sleeve together. (Fig. 17)
(6) Clean the welds of any flux and other impuri-
ties and grind smooth before proceeding with the
installation of the sleeve.
(7) Find the centerline of the sleeve and scribe a
centerline mark. Mark two additional lines 2 mm
(0.08 in.) on either side of the centerline mark to help
ensure the required 4 mm-6mm(0.16 in. - 0.24 in.)
weld root gap. (Fig. 17)
