Tooth Contact

1. Remove pinion sleeve assembly. Refer to "PINION SLEEVE ASSEMBLY ".
2. Apply red lead to drive gear.
   CAUTION: Apply red lead to both the faces of 3 to 4 gears at 4 locations evenly spaced on drive gear.
3. Install pinion sleeve shims and pinion sleeve assembly. Refer to "PINION SLEEVE ASSEMBLY ".
4. Remove the plug on the upper side of transfer case.

   When installing plug, apply sealant on screw part, and tighten it at the specified torque. Refer to "COMPONENTS ".

   • Use Genuine Silicone RTV or equivalent.  Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

• If the tooth contact is near the face (face contact), or near the heal (heel contact), thin pinion sleeve shims to move drive pinion closer to drive gear.

  Refer to "PINION SLEEVE SHIM ".

• If the tooth contact is near the flank (flank contact), or near the toe (toe contact), thicken pinion sleeve shims to move drive pinion farther from drive gear.

Refer to "PINION SLEEVE SHIM ".
