Torque Adapter For Fuel Injection Line Nut
On Mack model chassis that are equipped with ASET AI, AMI or AC engines, access to tighten the injection line nuts at the cylinder head can be limited, particularly at the No. 3 injection line on ASET AC engines.
A fuel injection line nut torque adapter (Tool No. 85109006) properly tightens these nuts. The adapter is designed to access the injection line nuts so that correct torque value can be applied.
When using this adapter, the torque value to be applied as measured on the torque wrench must be reduced according to the lengths of the wrench and adapter as outlined in Figure 1.
Use the formula provided to calculate the correct torque value. See Figure 2 for the correct torque values for some of the most common torque wrench lengths.
To apply proper toque, the torque adapter tool must be in line with the torque wrench. (See Figure 3.) In addition, there is limited space to turn the wrench before contact with the exhaust manifold is made.
Be sure to reposition the wrench during the tightening process to ensure that interface with the manifold does not affect the torque reading.
