NOTE: This will position all pistons (6108) below top of cylinder block deck face.
11. Position crankshaft on top dead center (TDC.) No. 1.
12. Remove timing chains.
13. Remove oil pump screen cover and tube (6622) and oil pump (6600).
14. Remove crankshaft oil slinger (6310) and crankshaft rear oil seal (6701) using Rear Crankshaft Slinger Remover T95P-6701-AH, Rear Crankshaft
Seal Remover T95P-6701-EH and Slide Hammer T50T-100-A.
15. Remove crankshaft rear oil seal retainer (6335).
NOTE: Connecting rods (6200), connecting rod caps and connecting rod bearings (6211) should be numbered to make sure they are assembled in
their original positions.
16. Turn crankshaft until connecting rod cap to be removed is accessible. Identify the connecting rods, connecting rod caps and connecting rod
bearings for cylinder position.
17. Remove the connecting rod cap and lower and upper connecting rod bearings. 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 engine damage may occur.
18. Connecting rod bolts (6214) are retained in the bolt 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 can.
19. Remove horizontal main cap side bolts from cylinder block (6010).
20. Loosen crankshaft main bearing cap adjusting screws (6C360) on bearing main caps.

INSTALLATION
NOTE: All sealing surfaces must be clean and free of chips, dirt, paint and foreign material. Also make sure oil passages are clear.
1. Lubricate with clean engine oil meeting Ford specification WSS-M2C910-A1 and install crankshaft main bearings into cylinder block. Install
crankshaft main bearings and crankshaft thrust main bearing into main bearing caps.
CAUTION: Use care when installing crankshaft or damage to the bearing corners or surfaces may occur.
2. Install crankshaft into cylinder block.
3. Push crankshaft rearward. Lubricate and install upper crankshaft thrust washer by rolling the crankshaft thrust washer onto machined shelf between
rear side of No. 5 bulkhead and thrust surface of crankshaft. Make sure coated side of crankshaft thrust washer with three 5 mm wide oil grooves
faces the crankshaft thrust surface.
NOTE: Crankshaft main bearing cap adjusting screws must be bottomed on main bearing caps prior to installation of main bearing caps.
