( 1 ) One 4H-1225 Washer is required for use between cylinder 6 and cylinder 8 on twelve cylinder engines. One 4H-1225 Washer is required for use between cylinder 8 and cylinder 10 on sixteen cylinder engines. The use of this component helps provide clearance between the lines for the oil mister and the plate (2) .
( 2 ) This component is required for use between cylinder 6 and cylinder 8 on twelve cylinder engines. This component is required for use between cylinder 8 and cylinder 10 on sixteen cylinder engines. The use of this component helps provide clearance between the lines for the oil mister and the plate (2) .
( 3 ) The location of these O-ring seals are not shown in the illustrations. These O-ring seals fit in grooves in the top and the bottom of the 135-8828 Seal Retainer Plate (1) .Installation Procedure
Use Disassembly and Assembly Module, SENR3594, "3612 and 3616 Diesel Engine" as a reference for this procedure. Use Illustrations 1, 2, and 3 as references for this procedure.
