Removal NOTE: The connecting rods and pistons can only be removed after prior removal of the engine cylinder head, oil pan and oil pump assembly as described in this section.
If necessary, remove any ridge from the top of the cylinder bores with a cylinder ridge, 1, reamer or 37 hand scraper. Do not cut down into the piston ring travel area. With the piston at the bottom of its stroke, remove the nuts from the bearing cap bolts and remove the bearing cap, 2, and liner, 1. Use the handle end of a hammer to push the pis- ton and rod assembly out of the top of the block.
Remove the bearing liner from the connecting rod. Turn the crankshaft to bring each piston to the bottom of its stroke and repeat this procedure. Keep the bearing caps and liners with their re- spective connecting rods.
Disassembly 1. Remove the piston pin retainer snap ring from each side of the piston and remove the pin. Use an expander to remove the piston rings.
Identify each piston and rod for reassembly. Wash the piston and connecting rod assembly in a suitable solvent and dry with a clean lint-free cloth or compressed air. Inspect the piston ring lands, skirts, and pin bosses for damage. Check for separation of the top ring insert from the piston.
Clean the ring grooves and using a new ring, 1, and feeler gauge, 2, check the piston ring lands for wear. Replace rings if the clearance is not within 0. Check the connecting rod components for dam- age and place each connecting rod, 2, in an 1 alignment fixture to check for distortion. Replace 3 if distorted beyond the following: Max. Measure the outside diameter of the piston pin and the inside diameter of the connecting rod bushing. If the clearance is not within 0.
After installation of a new connecting rod bush- ing, 1, use the hole in the top of the rod as a guide and drill a 6 mm 0. Use an expansion reamer to ream the bushing to obtain the specified bushing-to-piston pin clear- ance. Check the connecting rod and main bearing clearances as described in this section. If the bearing clearances exceed 0. Clean and inspect the cylinder block. Rust around the core plugs indicates leakage, and 43 new plugs should be fitted with suitable sealant.
Inspect and measure the cylinder bores for wavi- ness, scratches, scuffing, out-of-round, wear and taper. A wavy cylinder wall has a series of parallel lines or rings worn around the cylinder, within the ring travel area. These irregularities can be felt by running a finger over the surface. A scuffed cylinder can be identified by discolored areas.
Out-of-roundness, wear and taper can only be detected with a cylinder bore gauge. Measure lengthwise and crosswise to obtain di- mensions A, B, C, and D. Dimension A compared with B, and dimension C compared with D, indi- cates taper while the crosswise dimensions C and D compared to the lengthwise measure- ments A and B show if an out-of-round condition 44 exists. Taper Repair Limit: 0.
Wear Limit: 0. Out-of-Round Repair Limit: 0. If the cylinders are outside specification or the Bores to take 0.
All honing should be done honed or bored to fit the next oversize pistons. The finished bore size can be determined by After reboring and honing, thoroughly wash and measuring the piston diameter at right angles to dry the cylinder block and coat the walls with the piston pin and adding the appropriate piston- engine oil. Always bore the cylin- For cylinders with severely damaged walls or to der with the most wear first to determine the over- which maximum oversize pistons have already size pistons required.
Oversize pistons are avail- been installed, cylinder liners are available for able as follows: sleeving the bore. A lipped, thin wall sleeve is used in engines with a Block boring procedure for Bore the block to 0. The counterbore depth is critical as the sleeve must be flush with the block surface when installed. B If the block is skimmed, ensure the piston-to-block height dimension is within 0. Only standard and 0. Check the flatness of the cylinder block-to-head surface.
Resurface if not within 0. Prior to reassembly, check the piston-to-bore clearance as follows: Measure the cylinder bore diameter in a crosswise direction, then measure the piston diameter at right angles to the piston pin.
Subtract the piston diameter from the bore diameter and the resultant figure should be within the 0. NOTE: Pistons are available in both standard and oversizes. New pistons should be installed if the clearance exceeds the specified limits. If the clearance is greater than specified, try a similar new piston. If the clearance still exceeds the specified limit, measure the other cylinder bores and pistons and determine the cylinder with the greatest clearance.
Based on the greatest clearance, rebore the cylinders to take the next oversize piston as previously described in this section. If the clearance is less than specified, hone the bore to obtain the desired clearance as previously described in this section.
Lubricate all components with engine oil, then assemble the piston to the connecting rod with the notch, 1, on the piston crown aligned with the pip, 2, on the connecting rod and install the piston pin and retainers snap rings. Check the piston rings, 2, for minimum gap using a feeler gauge, 1, prior to installation in the rele- vant cylinder. Use a piston crown to squarely lo- cate the ring in the bore.
New rings should be checked for side clearance in the piston as pre- viously described in this section. Use an expander to install the piston rings, start- ing with the oil control ring in the bottom groove and working upwards. The service ring set comprises: 1 coiled wire expander for oil control ring 1 oil control ring 3 compression rings 48 Oil Control Ring Open the coiled wire expander to fully reveal the inner guide wire.
Position the coiled expander in the oil groove and insert the inner guide wire into the open end of the coil. Close the coil until the ends abut. Install the cast iron ring either side up with the inside groove over the coiled expander. Position the ring gap diametrically opposite the coiled wire ends.
NOTE: To facilitate assembly, the 2nd and 3rd compression rings are marked with a punched dot or the letters TOP engraved on their upper surfaces. Top Compression Ring Bright chrome finish with a chamfer on the inside diameter which must face upwards on assembly.
NOTE: Some top compression rings do not have a chamfer and may be installed either side up. After installing the rings, stagger the ring gaps around the circumference of the piston. After honing, thoroughly wash and dry the bores and coat the walls with oil. Select the correct bearing liners, as described later in this section, and install in the connecting rod and cap. Ensure the bearing liner tang lo- cates in the slots of the rod and cap. Turn the crankshaft to position the No.
Oil the pistons, rings, cylinder bore, and bearing liners. Use a compres- sor, 2, to install the piston into the cylinder. En- sure the notch on the top of the piston is toward the front of the engine. Using a hammer handle, 1, push the piston into the bore until the connecting rod bearing liner seats on the crankpin.
Install the connecting rod bearing cap with the number on the cap on the same side as the number on the rod. Install new nuts and tighten to 55 Nm 63 ft. Use feeler gauges to check the side clearance of each connecting rod. Replace or repair if not within 0. Install the remaining piston and rod assemblies in the same manner.

Measure the diameter of each journal in four places to determine out-of-round taper or wear. Measurement A compared with B indicates verti- cal taper while measurement C compared with D indicates horizontal taper. Measurements A and B compared with C and D indicate journal out-of- round.
If the journal exceeds the specified wear limit, refinish the journals to the next undersize bearing. Always reproduce the original journal side radii and after refinishing, chamfer the oil holes. Examine the rear oil seal journal for score marks. Remove minor imperfections with fine emery 52 cloth and, if severely damaged, replace the crankshaft. Reassembly 1.
Check the crankshaft bearing clearance with mi- crometers or preferably using Plastigauge as fol- lows: Position a piece of correct size Plastigauge across the full width of the bearing cap and approximately 6. Install the cap and tighten the bolts to the specified torque. Remove the cap and use the scale to check the width of the flattened Plastigauge.
The width of the Plastigauge at the widest point establishes the minimum clearance and, at the narrowest 53 point, the maximum clearance. The difference between the two readings is the taper. NOTE: Normally, main bearing journals wear evenly and will not be out-of-round. However, if a liner is fitted to an out-of-round journal which is within specifications, be sure to fit the bearing to the maximum diameter of the journal. Standard size liners are color coded red or blue Specifications Service Standards in this and are available in a copper lead or aluminum section.
Position the bearing liners in the block and caps and coat with oil. If the crankshaft has been refin- IMPORTANT: The engine may be assembled with ished, fit the correct undersize main bearing lin- liners of different material, but liners of the same ers.
