NOTE ON REPAIR WORK
REMOVAL
1.
As the center pillar reinforcement and side sill outer
reinforcement center are welded at the side sill, cut
the side outer panel at the position shown in the
illustration where the weld points of the reinforcement
can be seen, remove, and then remove the weld
points of the center pillar reinforcement.
2. To cut the weld points of the center pillar seatbelt
reinforcement and center pillar reinforcement, cut at the
bottom of the roof side rail inner as shown in the illustration.
NOTE
Keep the separated side roof rail inner (A) for the
future use.
INSTALLATION
1. Remove the side outer panel, side sill outer reinforcement
center, side sill bulkhead, and side sill reinforcement
support from the new center pillar.
2.
To ensure the strength of the cut area of the front
pillar, cut the side outer panel 30 mm above the cut
area.
Cut the new center pillar at the same positions.
3. To prevent damage of the center pillar seatbelt
reinforcement, align the new center pillar reinforcement
only to the body side and cut.
Caution
If the center pillar seatbelt reinforcement has been
damaged, repair by welding.
4. When attaching the center pillar reinforcement, apply
