Illustration 5. Installation of tool in fuel injection pump housing.The diameter of the drilled hole in the end of the tool is larger than the diameter of the hole in the fuel injection pump housing. The tool will release the roll pin as the tool is removed from the fuel injection pump housing.
After the roll pin is installed in the fuel injection pump housing, it must be installed to the correct depth. Install the 6V29 Sleeve Metering Fuel System Pump Roll Pin Tool into the correct pump assembly bore as shown in Illustration 5.
Use a small hammer and punch to install the roll pin until it makes contact with the tool as shown in Illustration 6. The roll pin will be at the correct depth. The tool is heat treated and the roll pin will not damage the tool when it makes contact with it.
