Note: Handle the fractured connecting rod with care. Use a soft jawed vise in order to hold the connecting rod while loosening the connecting rod cap bolts. Use a soft faced hammer in order to tap the connecting rod cap, if necessary.
Note: The connecting rod small end must be heated or cooled to achieve a difference of 80° to 90°C (176° to 194°F) before the installation of the piston pin bearing.
(A) Bore in the connecting rod for the piston pin bearing … 43.191 ± 0.013 mm (1.7004 ± 0.0005 inch)
(B) Bore in the piston pin bearing after installation of the bearing … 40.028 ± 0.008 mm (1.5759 ± 0.0003 inch)
(C) The bearing joint for the piston pin bearing must be positioned to the following angle above the centerline on either side. … 12 ± 5 degrees
(D) Distance for heating the connecting rod for the installation of the piston pin bearing … 75 ± 5 mm (3.0 ± 0.2 inch)
(E) Distance between the center of the connecting rod bores … 200 mm (7.9 inch)
(F) Bore in the connecting rod for the bearing for the crankshaft connecting rod journal … 75.000 ± 0.013 mm (2.9527 ± 0.0005 inch)
(G) Length of the bolts … 65.0 ± 0.5 mm (2.56 ± 0.02 inch)
Note: Use the following procedure to tighten the connecting rod bolts before measuring the crankshaft bore. Check the dimensions of the crankshaft bore only after the tightening procedure has been followed.
- Before installing the rod cap, clean the mating surfaces of the connecting rod with compressed air or a steel brush. Ensure that there are no loose particles that remain from the process that is used to fracture the rod.Note: Lubricate the seating faces of the rod cap bolts with 4C-5592 Anti-Seize Compound or clean engine oil before installing the bolts.
- Install new bolts (1) and torque the new bolts to 54 ± 7 N·m (40 ± 5 lb ft).
- Place an index mark on each connecting rod cap bolt and tighten each of the cap bolts for an additional 60 ± 5 degrees (1/6 of a turn).
