SWITCH-BASE 4556613 - Caterpillar

5P4149 Conversion Group and Special Instruction Form SMHS6700 are available for the conversion of the 8S2242 Nozzle Tester Group into the 5P4150 Tester Group. Installation of the conversion group permits a dealer to use the older tester to check the valves in both pencil-type and capsule-type fuel injection nozzles. The new 5P4150 Nozzle Tester Group already has the ability to check both types of valves.
After October 1, 1978, the 5P4149 Conversion Group will no longer be available for parts service. If you have the older 8S2242 Nozzle Tester Group and need the 5P4149 Conversion Group, order it now to make the conversion.
