Main Bearing Bedplate Installation For 2001-2006 Ford 3.0L VIN 1 Engines The AERA Technical Committee offers the following information regarding the main bearing bedplate installation for 2001-2006 Ford 3.0L VIN 1 engines. This information should be considered any time the crankshaft is being installed. This engine uses 22 fasteners for the lower engine bedplate which also house the lower main bearing shells. The bedplate assembly must be installed in its entirety and then removed to properly check main bearing clearance. Desired main bearing oil clearance is .0007-.0018" (.018-.045 MM). There are three different standard bearings, as shown in the chart below, available to assist in achieving the desired oil clearance. Stage 1. Torque Fasteners 1-8 (Small Bolts) in sequence to 18 ft/lbs. Stage 2. Torque Fasteners 9-16 (Large Bolts) in sequence to 30 ft/lbs. Stage 3. Rotate Fasteners 1-16 (Large & Small Bolts) in sequence an additional 90° turn. Stage 4. Torque Fasteners 17-22 in sequence to 18 ft/lbs. (SEE DIAGRAM TAB) Bearing Grade Bearing Thickness @ Crown 1 .0983” (2.498 MM) 2 .0985” (2.502 MM) 3 .0987” (2.507 MM) It is suggested keeping oil clearances toward the "tighter" specification to achieve the required 45 psi @ 448 rpm, normal pressure reading.
