Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

3. Place the Repair Plate against the floor pan and align the contour of the outer edge of
the Repair Plate with the pinch weld drains (see Figure 2).

4. Use locking pliers on the pinch welds to hold the Repair Plate in place (see Figure 2).

5. Use a scribe tool to make “location marks” at the front and rear edges of the Repair
Plate (see Figure 2).

6. Drill two holes in the floor pan (see Figure 2).
a. Use the existing holes in the Repair Plate for hole locations.
b. Use a 1/8 inch drill bit to make pilot holes in the floor pan.
c. Drill final size using a 33/64 inch (13.1 mm) drill bit.

8. Clean all of the undercoating and loose
rust off of the floor pan in the area shown
in Figure 3.


Use a grinder with a “cup type”
twisted wire brush attachment (or
equivalent).



Use low pressure compressed air to
blow off dust and debris.

WARNING: Wear eye protection when
performing the above steps to prevent
debris from entering eyes.

Clean this
area

NOTE: In some cases the floor pan may be bulged. If so, use a rubber mallet to tap the
floor pan back to a level/flat position.

9. Use isopropyl alcohol to clean (wipe down) the floor pan in the area that you cleaned
with the wire brush.

10. Install Rivet Nuts in the 13.1 mm (33/64
in) holes that you drilled in the floor pan.


Use Rivet Nuts included with the repair
kit listed in the Parts Information.



Refer to the Rivet Nut Installation
Instructions on the next page.

11. Completely and liberally coat the cleaned area with DuPont Etch Primer (P/N A4119S) or equivalent.


Follow all product instructions.



A second coat may be needed for heavy rust spots.



Let each coat dry for 5 minutes.

12. Prepare for application of LORD Fusor® 108B structural adhesive (see Figures 5 and 6).
a. Load cartridge of Fusor® 108B into the 2:1 dispensing gun.
b. Remove the cartridge cap and plugs (if this is the second use for this cartridge,
remove the old nozzle).
c. Dispense/expel some material from the cartridge to make sure any hardened
material is expelled.
d. Install a new mixing nozzle onto the cartridge.
 Make sure the nozzle retainer is installed (see Figure 5).
NOTE:
 Mixing nozzles are one-time use only. Do not reuse mixing nozzles.
 Two mixing nozzles are included with each cartridge of Fusor® 108B.
 Refer to the Parts Information for additional product details.
 For cleanliness, using rubber gloves is recommended.

e. Dispense 2 beads of Fusor® 108B
onto a paper that will be discarded.


Each bead should be about ¼
inch diameter and about 6
inches long (length of the
nozzle).
NOTE: Performing this action
will ensure the dispenser
plungers have leveled, air
bubbles have been expelled,
and adhesive is mixed correctly.

Figure 6

13. Liberally apply Lord Fusor® 108B to the back side of the Repair Plate as shown in
Figure 7.
 The adhesive bead should be about ¼ inch diameter in all the areas shown.

Yellow color has been used for
illustrative purposes to indicate an area
that application is optional based on the
size of rust perforation. If the rust
perforation area is extensive (large)
adhesive should not be applied here

14. Install the Repair Plate, securing it with two retaining bolts threaded into the Rivet Nuts
(see Figure 8).


Use the bolts included with the repair kit listed in the Parts Information.



Do not use air tools to tighten the bolts.



Torque bolts to 50 N•m (37 ft-lb).

15. Use locking pliers, two C-clamps, and two blocks of wood to securely fasten the Repair
Plate to the floor pan (see Figure 8).


Gently tap on the blocks of wood with a dead blow mallet to ensure Repair Plate is
tight against the floor pan.



IMPORTANT: Clean excess adhesive from around the edges of the Repair Plate
before the adhesive cures.



Allow the adhesive to cure for at least 1 hour.
NOTE: If the locking pliers and C-clamps are angled as shown in Figure 8, the
vehicle can be lowered and moved off the lift while adhesive is curing.
