Please note this change in the appropriate module. This change is in the third paragraph of the section. The change is shown in the text that follows:When a fuel injection pump is installed correctly, the plunger is through the sleeve and the adjustment lever is engaged with the groove on the sleeve. The bushing that holds the fuel injection pump in the fuel injection pump housing must be kept tight.On engines with a horsepower rating of 325 horsepower or less, tighten the bushing to a torque of 95 7 N m (70 5 lb ft).On engines with a horsepower rating that is greater than 325 horsepower, the bushings should be replaced, if the bushings have been removed. On engines with a horsepower rating that is greater than 325 horsepower, perform the following procedure to tighten the bushings.
Tighten the bushing to a torque of 95 7 N m (70 5 lb ft).
Loosen the bushing for 15 degrees.
Tighten the bushing again to a torque of 95 7 N m (70 5 lb ft).Damage to the fuel injection pump housing will result if the bushing is too tight. If the bushing is not tight enough, the fuel injection pump will leak.
