Rework Procedure


 
Note: This Design may cause the Bracket to contact the casting of the Oil Cooler Bypass. Inspect the clearance between the bracket and the casting of the Oil Cooler Bypass. Prior to assembly the following must be checked

1. Place ONLY the 164-6819 Spacers in their location against the Oil Cooler Bypass casting. (reference Image1.1.1)

2. Using a straight edge ensure there is no contact with the housing (A). (reference Image1.1.2)

3. If Required: Lightly polish the casting to allow for no contact between the straight edge and the casting.
