Section 14 - Engine Testing - Group 14 Engine Dynamometer - Install Engine (14-01) M11 Page 14-25 Air Inlet Restriction Connect a water manometer to the air inlet pipe of the turbocharger to measure inlet restriction. The manometer adapter must be installed at a 90 degree angle to the air flow in a straight section of pipe, one pipe diameter before the turbocharger. NOTE: A vacuum gauge can be used to record the intake air restriction. Minimum Gauge Capacity: 760 mm H 2 0 [30 inches H 2 0]. Exhaust Restriction Connect a mercury manometer to a straight section of the exhaust piping one pipe diameter from the turbocharger outlet to measure exhaust restriction.
Protect the hose from heat by using a 305 mm [12 in] minimum length of metal tubing leading from the exhaust pipe connection. Minimum Gauge Capacity: 254 mm Hg [10 inches Hg]. Lubricating Oil Temperature Use a Compulink™to monitor the lubricating oil tempera- ture. Refer to the Compulink™Manual, Bulletin No. 3810472, for correct operation. Lubricating Oil Pressure Remove the pipe plug from the main oil rifle drilling in the cylinder block. Install the lubricating oil pressure gauge, Part No. 3375275.
