Oil Pans with Full Circumference Clamping Plates for ISB6 Oil Pans with Full Circumference Clamping Plates for ISB6.7 Bus Applications ISB6.7 2010 and ISB6.7 2013 OP 9655 and OP 9655 RPS Project # MSUS-8YQH46

Project Scope Change Summary: Full perimeter clamping plates will be added to oil pans used on bus applications. The OP option on the engine specs for bus applications will need to be changed. Bus fuel ratings will only be compatible with oil pans with full perimeter clamping plates. Background: To increase the residual cap screw torque and break away torque on the cap screws used to attach the oil pan to the engine. Implementation Strategy and Date: Fix as fails for engines built before plant implementation. Plant Implementation February 25, 2015
