1. Thoroughly clean the surfaces at location (A) and location (B).

2. After the parts are clean and dry apply Loctite® Primer (1) to separator plate (3) and location (A) .

   Note: Make sure to get the Loctite® Primer all around the bolt clearance holes as shown at location (C) .

3. Let the Loctite® Primer dry.

4. Then apply Loctite® (2) to separator plate (3) and location (A) .

   Note: Specifically apply sealant to the circled landings around the bolt holes as shown in location (C). Sealant applied toward the inside of the o-ring groove on separator plate (3) is acceptable. Do not apply sealant down inside of the o-ring groove.

5. Install the o-ring seal to separator plate (3),

6. Immediately assemble separator plate (3) to the torque converter housing.

7. Tighten the bolts to normal torque.

8. Allow time for the Loctite® to cure before pressurizing.
