C1.5 and C2.2 Engines for Caterpillar Built Machines Caterpillar

Note: If a fuel injection pump is removed, replace the old shims with new shims of the same thickness. Old shims must not be reused.

Note: If the thickness of the shim is 0.5 mm (0.0197 inch) or the thickness of the shim is below 0.5 mm (0.0197 inch), install beaded shims. If the shim thickness is above 0.5 mm (0.0197 inch), install the non-beaded shim. Then install the beaded shim. Ensure that the beading on the beaded shim faces upward, toward the bottom of the fuel injection pump.

Note: If there are three shims installed, the non-beaded shim is always installed on the inside. If only one or two shims are installed, all shims are beaded.

On C1.5 engines, select the correct combination of shims from table 1.

On C2.2 engines, select the correct combination of shims from table 2.

If the original shim thickness cannot be determined, contact the Dealer Solution Network. The user must provide the full engine number of the product that is serviced.
