Rod, Piston And Connecting: Installation: Installation
WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
- Lubricate the cylinder bores with clean engine oil.
- Generously lubricate the rings and piston skirts with clean engine oil.
- Orientate the rings on the piston. Refer to STANDARD PROCEDURE .
- Using a piston ring compressor, compress the rings (1). If using a strap-type ring compressor, make sure the inside end of the strap does not hook on a ring gap and break the ring.
- Rotate the crankshaft so the rod journal for the piston to be installed is at BDC (Bottom Dead Center).
- Make sure the front of the piston is oriented properly according to the marking on the top of the piston and the connecting rod is oriented properly.
- Position the piston and rod assembly into the cylinder bore with the front of the piston oriented properly according to the stamping in the top of the piston. Use care when you install the piston and connecting rod so the cylinder bore is not damaged. The long side of the connecting rod must be installed on the exhaust side of the engine.
- Push the piston into the bore until the top of the piston is approximately 50 mm (2 in.) below the top of the block. Carefully pull the connecting rod onto the crankshaft journal.
- For fractured/split type connecting rods, the long end of the rod must be installed away from the intake side of the engine. The connecting rod split/face must face toward the same side as the piston notch feature on the skirt. The split face will face toward the exhaust side of the engine if properly installed.
- Using clean engine oil, lubricate and install the correct size connecting rod bearings (6).
- Using clean engine oil, lubricate the threads and under the heads of the connecting rod bolts (7).
- Install the rod cap (2) and bolts (1) to the connecting rod. Tighten the connecting rod bolts evenly in 3 steps:
- Tighten bolts (1) to 30 N.m (22 ft. lbs.).
- Tighten bolts (1) to 60 N.m (44 ft. lbs.).
- Tighten bolts (1) an additional 60° clockwise.
- The crankshaft must rotate freely. Check for freedom of rotation as the caps are installed. If the crankshaft does not rotate freely, check the installation of the rod bearing and the bearing size.
- Measure the side clearance between the connecting rod and the crankshaft. DO NOT measure the clearance between the cap and crankshaft.
NOTE:
Note: For 2013 the oil jet cooling nozzle is green in color and can't be used in older prior model years and older model years can't be used in 2013 model year engine.
- Install the oil jet piston cooling nozzles (1). Tighten bolt (2) to 15 N.m (133 in. lbs.).
- Install block stiffener (2). Tighten bolts to (1) 43 N.m (32 ft. lbs.).
- Using a new gasket, Install the suction tube (1). Tighten bolts:
- M8 bolts (3) to 24 N.m (18 ft. lbs.).
- M10 bolts (2) to 43 N.m (32 ft. lbs.).
- Install the oil pan (2). Refer to PAN, OIL, INSTALLATION, 6.7L .
- Install the cylinder head. Refer to CYLINDER HEAD, INSTALLATION, 6.7L .
- Install the engine into vehicle. Refer to INSTALLATION, 6.7L .
- Install a new filter and fill the crankcase with new engine oil. Prefill the filter with clean oil.
- Connect both negative battery cables.
- Start engine and check for leaks.
