Scheme 605: Main Bearing Clearance Inspection

Scheme 606

To check main bearing-to-journal oil clearance, remove the lower block and the bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(/acura/tsx/ii-2008-2014/remont/mechanical/#engine-block-4-cyl) ).
Clean each main journal and the bearing half with a clean shop towel.
Place one strip of plastigage across each main journal.
Reinstall the main bearings and the lower block, then torque the bolts to 29 N.m (3.0 kgf.m, 22 lbf.ft). NOTE: Apply new engine oil to the bolt threads and flanges. Do not rotate the crankshaft during inspection.
Tighten the bearing cap bolts an additional 48°.
Remove the lower block and the main bearings again, and measure the widest part of the plastigage. Main Bearing-to-Journal Oil Clearance No. 1, 2, 4, 5 Journals: Standard (New): 0.017-0.041 mm (0.00067-0.00161 in) Service Limit: 0.050 mm (0.00197 in) No. 3 Journal: Standard (New): 0.025-0.049 mm (0.00098-0.00193 in) Service Limit: 0.055 mm (0.00217 in)
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 appropriate color code(s), and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.
If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below the current one), and check 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/tsx/ii-2008-2014/remont/mechanical/#engine-block-4-cyl) ).

Scheme 607

Scheme 607: Crankshaft Bore Code Location

Numbers, letters, or bars have been stamped on the end of the lower block as a code for the size of each of the five main journal bores. Write down the block bore codes. If you cannot read the codes because of accumulated dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.

Scheme 611: Connecting Rod Bearing Selection

Scheme 612

Inspect each connecting rod for cracks and heat damage. Big End Bore Code Locations
Each connecting rod has a tolerance range from 0 to 0.024 mm (0.00094 in), in 0.006 mm (0.00024 in) increments, depending on the size of its big end bore. It's then stamped with a number or bar (1, 2, 3, or 4/1, II, III, or IIII) indicating the range. You may find any combination of numbers and bars in any engine. (Half the number or bar is stamped on the rod cap, the other half is on the connecting rod.)

Scheme 636: Cylinder Bore Honing

Measure the cylinder bores (see «BLOCK AND PISTON INSPECTION»(/acura/tsx/ii-2008-2014/remont/mechanical/#engine-block-4-cyl) ). If the engine block is to be reused, hone the cylinders, and remeasure the bores. Only a scored or scratched cylinder bore must be honed.
Remove the oil jets (see «OIL JET REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/lubrication-system/#engine-lubrication-4-cyl) ).
Hone the cylinder bores with honing oil and a fine (400 grit) stone in a 60 degree cross-hatch pattern (A). NOTE: Use only a rigid hone with 400 grit or finer stone such as Sunnen, Ammco, or equivalent. Do not use stones that are worn or broken.
When honing is complete, thoroughly clean the engine block of all metal particles. Wash the cylinder bores with hot soapy water, then dry and oil them immediately to prevent rusting. NOTE: Never use solvent, it will only redistribute the grit on the cylinder walls.
If scoring or scratches are still present in the cylinder bores after honing to the service limit, rebore the engine block. Some light vertical scoring and scratching is acceptable if it is not deep enough to catch your fingernail, and does not run the full length of the bore.

Install the transmission: Manual transmission (see «TRANSMISSION INSTALLATION»(ref-475400-S31595137952012052300000) ) Automatic transmission (see «TRANSMISSION INSTALLATION»(/acura/tsx/ii-2008-2014/remont/automatic-trans/#automatic-transmission-4-cyl) )
Install the engine/transmission (see «ENGINE INSTALLATION»(/acura/tsx/ii-2008-2014/remont/mechanical/#engine-assembly-4-cyl__engine-installation) ). NOTE: Whenever any crankshaft or connecting rod bearing is replaced, run the engine at idle until it reaches normal operating temperature, then continue to run it for about 15 minutes.

Remove the crankshaft from the engine block (see «CRANKSHAFT AND PISTON REMOVAL»(/acura/tsx/ii-2008-2014/remont/mechanical/#engine-block-4-cyl) ).
Remove the CKP pulse plate (A) from the crankshaft (B). NOTE: Be careful not to damage the journal and the CKP pulse plate.
Install the CKP pulse plate in the reverse order of removal.

Note. When installing the crankshaft, refer to the crankshaft installation procedure (see CRANKSHAFT INSTALLATION ).
