4. If the connecting rod end play is beyond the service limit, install a new connecting rod and recheck. If it is still beyond the service limit, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(/acura/zdx/i-2009-2013/remont/mechanical/#engine-block) ).
5. Push the crankshaft firmly away from the dial indicator by prying, and zero the dial against the end of the crankshaft.

Scheme 282

1. Remove the main bearing caps and the bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(/acura/zdx/i-2009-2013/remont/mechanical/#engine-block) ).
2. Clean each main journal and bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal. NOTE: If the engine is still in the vehicle when you bolt the main cap down to check the clearance, the weight of the crankshaft and the drive plate will flatten the plastigage further than just the torque on the cap bolt and give you an incorrect reading. For an accurate reading, support the crank with a jack under the counterweights, and check only one bearing at a time.
4. Reinstall the bearings and the main bearing caps, then torque the bearing cap bolts to 74 N.m (7.5 kgf.m, 55 lbf.ft), and the bearing cap side bolts to 49 N.m (5.0 kgf.m, 36 lbf.ft) in the proper sequence (see step 22 ). NOTE: Apply new engine oil to the bolt threads and flanges. Do not rotate the crankshaft during inspection.
5. Remove the main bearing cap and the bearing half, and measure the widest part of the plastigage. Main Bearing-to-Journal Oil Clearance Standard (New): 0.019-0.045 mm (0.00075-0.00177 in) Service Limit: 0.050 mm (0.00197 in)
6. If the plastigage measures too wide or too narrow, remove the crankshaft, and remove the upper half of the bearing. Install a new, complete bearing with the same color code, and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.
7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below that one), and check the clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over (see «CRANKSHAFT AND PISTON REMOVAL»(/acura/zdx/i-2009-2013/remont/mechanical/#engine-block) ).

Block Bore Code Locations

Letters or bars have been stamped on the end of the engine block as a code for the size of each of the four main journal bores.

Use them, and the numbers or bars stamped on the crankshaft (codes for main journal size), to choose the correct bearings. If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.

7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below that one), and check the clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over (see «CRANKSHAFT AND PISTON REMOVAL»(/acura/zdx/i-2009-2013/remont/mechanical/#engine-block) ).

Connecting Rod Bearing Selection

Each connecting rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.00095 in), in 0.006 mm (0.00024 in) increments) depending on the size of its big end bore.

It is then stamped with a number or bar (1, 2, 3, or 4/I, II, III, or IIII) indicating the range. You may find any combination of 1, 2, 3, or 4/I, II, III, or IIII in any engine.

If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes. If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply the new liquid gasket.
4. Install the oil pan on the engine block.
5. Tighten the bolts in three steps. In the final step, torque the bolts, in sequence, to 12 N.m (1.2 kgf.m, 9 lbf.ft). NOTE: Wait at least 30 minutes before filling the engine with oil. Do not run the engine for at least 3 hours after installing the oil pan.
6. Tighten the four bolts (A) securing the transmission, then install the torque converter case cover (B).
7. Connect the CKP sensor connector (A), then install the CKP sensor cover (B) and the bolt (C).
8. Install the rear warm up TWC bracket.
9. If the engine is still in the vehicle, do the following steps.
10. Install exhaust pipe A using new gaskets and new self-locking nuts (see step 31 under «ENGINE INSTALLATION»(/acura/zdx/i-2009-2013/remont/mechanical/#engine-assembly__engine-installation) ).
11. Install the front subframe stiffener (see step 32 under «ENGINE INSTALLATION»(/acura/zdx/i-2009-2013/remont/mechanical/#engine-assembly__engine-installation) ).
12. Install the splash shield (see «FRONT SPLASH SHIELD REPLACEMENT»(/acura/zdx/i-2009-2013/remont/exterior-body-panels/#fenderwell__front-splash-shield-replacement) ) and the engine undercover (see «ENGINE UNDERCOVER REPLACEMENT»(/acura/zdx/i-2009-2013/remont/exterior-body-panels/#fenderwell__engine-undercover-replacement) ).
13. Refill the engine with engine oil (see «ENGINE OIL REPLACEMENT»(/acura/zdx/i-2009-2013/remont/lubrication-system/#engine-lubrication) ).
