CYL GP-140 775 Y 20R5304 - Caterpillar

Dimensions for machining the cylinder block to use the 115-5234 Shaft (oversize fuel pump drive idler). (X) = vertical distance from center line of crankshaft to center line of bore for idler shaft = 106.617 .03 mm (4.1975 .001 in). (Y) = horizontal distance from center line of crankshaft to center line of bore for idler shaft = 36.289 .03 mm (1.4287 .001 in). (Z) = dimension of bore for oversize idler shaft = 26.194 .013 mm (1.0312 .0005 in) diameter, 25.5 .5 mm (1.00 .02 in) deep.The new 115-5234 Shaft (oversize fuel pump drive idler) can be used to replace the 4N-0098 Shaft if the bore in the cylinder block is machined oversize. The illustration shows the dimensions for machining the cylinder block to use the new oversize shaft.
