Connecting Rod Bearing: Service and Repair
Removal & Installation
REMOVAL
1. Remove oil pan (6675) and oil pump screen cover and tube (6622).
NOTE: Connecting rod caps, connecting rods (6200) and connecting rod bearings (6211) should be numbered to make sure they are assembled in
their original positions.
2. Turn crankshaft (6303) until connecting rod bearing to be removed is accessible. If more than one connecting rod bearing is being removed,
identify the connecting rod caps, connecting rods and connecting rod bearings for cylinder position.
3. Remove the connecting rod cap, lower connecting rod bearing and upper connecting rod bearing. Keep cap and connecting rod bearings together.
Use care to prevent damage to the bearing, cylinder bore and crankshaft surfaces.
CAUTION: Care should be taken not to damage the fractured rod and cap joint face surfaces or possible damage to engine may occur.
4. Connecting rod bolts (6214) are retained in the connecting rod cap hole with a light press fit. The connecting rod bolts have been torqued to yield
at least twice and must be discarded. Use a. hammer and punch to drive connecting rod bolts from connecting rod cap.
5. Inspect the connecting rods, connecting rod caps and crankshaft.
INSTALLATION
1. Clean crankshaft connecting rod journals with a clean cloth.
2. Lubricate crankshaft and connecting rod bearing surfaces with clean engine oil meeting Ford specification WSS-M2C910-A1.
CAUTION: Be sure not to scratch cylinder wall or crankshaft journal with connecting rod. Pull piston (6108) down until connecting rod bearing
seats on crankshaft journal.
3. Install upper connecting rod bearings in the connecting rod. Align retaining tang of connecting rod bearing with notch in connecting rod.
NOTE: Due to the use of a cracked connecting rod joint face surface, the connecting rod cap must be properly aligned to the connecting rod. The
connecting rod and connecting rod cap bearing tangs should be located on the same side of the connecting rod.
4. Install lower connecting rod bearings in the connecting rod caps. Align retaining tang of connecting rod bearing with notch in connecting rod cap.
5. Alternately tighten connecting rod cap bolts in three steps:
a. Tighten to 20-25 Nm (15-18 ft. lbs.).
b. Tighten to 40-45 Nm (30-33 ft. lbs.).
c. Tighten an additional 90-120°.
NOTE: After all connecting rod cap bolts are tightened to specification, rotate the crankshaft to make sure of smooth operation.
6. Check connecting rod side clearance using Dial Indicator with Bracketry TOOL-4201-C or equivalent. Clearance should be 0.15-0:45 mm
(0.006-0.0177 inch). If side clearance is greater than maximum service limit of 0.50 mm (0.020 inch), replace connecting rods and/or crankshaft.
7. Install oil pump screen cover and tube and oil pan with new oil pan gasket (6710).
