Rod Bearing Cap Torque Values

^ A plastic zone tightening method is used for tightening connecting rod bolts and nuts. Check the old bolts for deformation before re-using them.
^ Ensure that the connecting rod nut can be screwed smoothly as far as the bolt thread end. If this is not possible, use slide calipers to measure the outside diameter of the narrowest thread part of the bolt at 16 mm (0.63 inch) from the thread end. Replace the connecting rod bolt and nut, if under the limit.
^ The standard value is 7.90 - 8.00 mm (0.3110 - 0.3150 inch) and the limit is 7.75 mm (0.3051 inch).
^ Install connecting rod caps.





^ Lubricate threads and seat surfaces with new engine oil. Tighten connecting rod bearing cap nuts to 19 - 21 Nm (14 - 15 ft. lbs.). Then, turn the nuts an additional 90 - 95° clockwise with an angle wrench.
