START BY:a. remove fuel filter and base1. Drain the coolant from the engine.
Do not disconnect the air line from the compressor governor until the air pressure is zero.
2. Loosen the bleed valve and release the air pressure in the air tank. 3. Disconnect air compressor line (1) and fuel ratio control line (2) from the aftercooler housing. 4. Remove four turbocharger tube adapter to aftercooler housing bolts (3), nuts and cover. Loosen turbocharger compressor housing clamp (4), and rotate turbocharger tube (5) out of the way of the aftercooler housing. 5. Fasten tooling (A) and a hoist to aftercooler housing (6). Remove bolts (7) that hold the aftercooler housing to the cylinder head assembly. Remove the aftercooler housing from the engine. The weight is 36 kg (80 lb.).Install Aftercooler Housing

Put 9S3263 Thread Lock on the threads of the bolts, and install the bolts that hold the aftercooler housing to the cylinder head assembly. 4. Rotate turbocharger tube (3) into position. Place a gasket between the aftercooler housing and adapter, and install four bolts and nuts that hold it. Tighten turbocharger clamp nut (4) to a torque of 18 3 N m (13 2 lb.ft.). Lightly hit all around the clamp with a soft faced hammer, and tighten the clamp nut again to the same torque value. 5. Connect air compressor line (5) and fuel ratio control line (6).6. Fill engine with coolant to the correct level. See the Maintenance Guide.END BY:a. install fuel filter and base
