Section E: Rustproof Treatment
1. Mark the arms (Locations A & B) and crossmember (Location C) as shown on both sides. (Figure 3).
IMPORTANT:
If you are performing this treatment after replacing parts as specified under Section F, only necessary to rustproof the remaining original components. Replacement parts for this campaign have already been treated.
2. Wearing goggles and a mask, center punch and drill all six (6) marked locations with a 4 mm diameter drill bit.
NOTE:
A sharp drill bit and an occasional application of oil to the bit will aid in the drilling process.
CAUTIONS!
a) Be careful not to drill the opposite inside of the arms or the torsion bar inside the crossmember.
b) Metal filings from drilling may be hot. Gloves are recommended.
3. Widen point A only on the arms, and point C on the crossmember using a 10 mm diameter drill bit. (Refer to Note and Cautions above.)
Note:
File off any burrs caused by drilling.
4. Clean, as best as possible, all outer areas of control arms and crossmember to be treated.
5. Apply sealant to the openings at both ends of the arms (indicated by shaded arrow) as shown in Figure 4 (a quantity about the size of a 1" ball). DO NOT apply sealant to the openings on the underside of the outer end (indicated by non-shaded arrow) as this will serve as a drain hole.
6. Place a cloth, shop rag, etc. around the backing plate to protect the brake parts from seepage of the rustproof oil. (Figure 5)
7. Prepare for spraying of rustproofing oil.
CAUTIONS!
a) Wear goggles and a mask.
b) Keep spray away from flames or sparks. (Refer to the material safety data information on the label.)
c) Some overspraying may result, depending on experience. Should overspray get on vehicles or equipment in the area, clean affected areas off with a solvent that will not damage painted surfaces.
d) Adjust spray gun regulator to 85 psi.
e) Test sprayer by spraying in a pan first.
f) Oil will drip out of the holes drilled. Place a pan under these areas.
g) Move the "L" shaped nozzle in a circular, up and down motion to ensure adequate coverage.
h) Pull the trigger of the spray gun completely.
8. Spray the rustproof oil for 5 seconds inside each arm (approximately 1/6 of can).
NOTE:
SPRAYING TIMES SHOWN ARE ESTIMATES ONLY AND MAY BE ADJUSTED SLIGHTLY ACCORDING TO THE AMBIENT TEMPERATURE AND PREVIOUS APPLICATION EXPERIENCE. GENERALLY, THE APPLICATION TIMES WILL BE LESS IN WARMER TEMPERATURES.
9. Spray rustproof oil on the inside of the crossmember. Spray above the torsion bar (about 5 mm from the top of the crossmember tube - see Figure 6) for about 8 seconds toward the center first and 2 seconds toward the outside on each side.
NOTE:
TOTAL QUANTITY OF OIL USED FOR TREATMENT OF BOTH ARMS AND THE CROSSMEMBER = 1/3 CAN.
10. Save any remaining oil, clean out the spray gun and nozzle. After cleaning, fill the spray gun tank with rustproof wax.
11. Adhering to the same precautions under application of the oil, spray rustproof wax on the insides of the arms about 45 seconds each, and inside the crossmember for about 60 seconds - each side.
12. Apply the plug kits to the 10 mm holes at Point A on each arm and point C on the crossmember (Figure 3) and fill the 4 mm hole (Point B) with sealant.
NOTE:
IF THE PLUG ROTATES WHILE TIGHTENING THE SCREW, HOLD THE OUTSIDE OF THE PLUG WITH PLIERS.
13. Now apply the rustproof wax evenly to the outside of both arms and the outside of the crossmember. (Spraying time for the arms is about 30 seconds each, and for the crossmember 60 to 90 seconds.)
NOTE:
TOTAL QUANTITY OF WAX USED FOR TREATMENT OF BOTH ARMS AND THE CROSSMEMBER = 1 CAN.
14. Clean out the spray gun, tank, and wand.
15. Clean any overspray from the backing plate and/or other surfaces not included in treatment.
16. Re-install and torque rear wheel assemblies in their original positions.
