OVERHAUL


CYLINDER HEAD

NOTE: Before grinding valves or valve seats, measure installed valve height and record measurements for reassembly reference.

Cylinder Head
Measure cylinder head warpage. If warpage exceeds specification, resurface cylinder head. If resurfacing reduces cylinder head height to less than specification, replace cylinder head. Maximum resurface limit of cylinder head and/or cylinder block combined is .008" (.20 mm).

Valve Springs
Measure valve spring free length, out-of-square and pressure. If measurements are not within specification, replace springs.

Valve Stem Oil Seals
Install spring seat. Using Valve Stem Oil Seal Installer (J-38955), seat NEW oil seal onto valve guides.

Valve Guides
1. Heat cylinder head to 302-320°F (150-160°C). Using press or hammer and drift, force guide out of cylinder head from combustion chamber side. Allow head to cool to room temperature.
2. Ream valve guide bore to specification. Reheat cylinder head. Press guide into cylinder head until installed height is as specified in CYLINDER HEAD table. See Fig. 18 . Use reamer to finish reaming valve guide I.D. to specification.

Fig. 18: Measuring Installed Valve Guide Height (Protrusion)
Engines18
Valve Seat
1. If seat width is less than specified, machine or replace seat as necessary. Before servicing or replacing valve seat, repair valve guides. Bore valve seat until it collapses. Remove seat. Ream valve seat bore for .020" (.51 mm) oversize valve seat.
2. Heat cylinder head to 302-320°F (150-160°C). Press seat into bore until fully seated. Grind or cut valve seat. After machining, lap valve seat with lapping compound.

Valves
Measure valve face angle, head diameter, margin, length and stem diameter. Replace valve if measurements are not within specification. If grinding valve stem tip, DO NOT exceed valve tip maximum refinish specification.

CYLINDER BLOCK ASSEMBLY

NOTE: Number on top of piston does not indicate cylinder number; it is a grade number used to determine piston diameter.

Piston and Rod Assembly
1. Cylinder number is stamped on connecting rod and bearing cap. Before disassembling piston and rod assembly, mark cylinder number on piston. To separate piston and connecting rod, remove snap ring from piston. Heat piston in oil to 140-158°F (60-70°C). Press piston pin out of connecting rod. Remove remaining snap ring.
2. Measure rod bend and twist. If bend and twist exceed specification, replace rod. Measure piston pin bore diameter, piston fit and rod fit. If measurements are not within specification, replace piston, rod bushing and/or piston pin. If replacing rod bushing, align oil holes. Ream new bushing until rod fit is as specified.
3. To reassemble piston and rod, install NEW snap ring in piston. Heat piston in oil to 140-158°F (60-70°C). Orient rod in relation to piston so front mark on piston will face front of engine, and cylinder number on rod will face left side of engine.
4. Press pin through piston pin bore and rod bushing bore. Install remaining NEW snap ring. Ensure rod is centered on pin. Ensure connecting rod swings freely. Install piston and rod assembly with front mark on piston toward front of engine.

Fitting Pistons
1. Measure cylinder bore diameter at middle of bore. Measure piston diameter 2.05" (52.1 mm) from top of piston, at 90-degree angle to piston pin.
2. If piston clearance is not within specification, replace pistons with appropriate standard size piston, or bore all cylinders and install oversize pistons.
3. Before boring, install main bearing caps and tighten bolts to specification to prevent cylinder distortion. If installing standard diameter piston, ensure grade number on top of piston matches grade number stamped on cylinder block deck, left of each cylinder.

Piston Rings
When installing piston rings, ensure punch mark on ring faces upward. See Fig. 19 . If no mark is present, rings can be installed in either direction. Ensure ring end gaps are properly spaced around circumference of piston.

Fig. 19: Installing Piston Rings and Positioning End Gaps
Engines19
Rod Bearings
1. If journal out-of-round or taper exceeds specification, grind rod bearing journal and install undersize bearings.
2. Measure rod bearing diameter with bearing caps installed and bolts tightened to specification. If oil clearance is not within specification, replace bearings with NEW standard size bearings.
3. Standard size bearings are available in 3 sizes. To determine bearing size for specific journal, check connecting rod grade number on crankshaft throw. See Fig. 20 . Connecting rod grade number represents bearing diameter. If clearance is still not as specified after installing standard size bearings, grind rod bearing journal, and install undersize bearings.
4. If rod side play exceeds specification, replace rod or crankshaft as necessary.

NOTE: Upper and lower main bearings are not interchangeable. Upper bearings have an oil groove or hole. Ensure main bearing oil feed holes in block are clear.

Crankshaft and Main Bearings
1. Before removing crankshaft, check crankshaft end play. Loosen main bearing cap bolts in 2 or 3 steps, starting outside and working inward. If crankshaft runout exceeds specification, replace crankshaft.
2. If journal out-of-round or taper exceeds specification, grind main bearing journal, and install undersize bearings. After grinding, ensure fillet roll thickness exceeds .004" (.10 mm).
3. Measure main bearing diameter with bearing caps installed and bolts tightened to specification. If oil clearance is not within specification, replace bearings with new standard size bearings.
4. Standard size bearings are available in 3 sizes. To determine bearing size for specific journal, check crankshaft grade number on crankshaft throw. See Fig. 20 . Check cylinder block grade number on bottom of cylinder block, on right oil pan gasket surface. Grade number on crankshaft throw represents journal diameter. Grade number on cylinder block represents main bearing block bore diameter.
5. Add grade number on cylinder block to grade number on crankshaft throw to obtain crankshaft main bearing grade number. Each bearing grade number corresponds to a bearing color. Install bearing with appropriate color code. If clearance is still not as specified after installing new standard size bearings, grind main bearing journal, and install undersize bearings.
6. Before tightening main bearing cap bolts, shift crankshaft forward. Tighten cap bolts in 2 or 3 steps, starting at center bearing and working outward. Ensure crankshaft rotates smoothly.

Fig. 20: Locating Crankshaft and Cylinder Block Grade Numbers
Engines20
Thrust Bearing
Thrust bearing is part of main bearing No. 3. To measure crankshaft end play, shift crankshaft in either direction as far as it will go. Measure clearance between thrust bearing surface and crankshaft surface (end play). If end play is not as specified, replace thrust bearing.

Cylinder Block
1. If maximum deck warpage exceeds specification, resurface deck. If resurfacing reduces deck height to less than minimum specification, replace cylinder block. Maximum resurfacing limit of cylinder head and/or cylinder block combined is .008" (.20 mm).
2. If cylinder bore diameter, maximum taper or maximum out-of-round exceed specification, bore all cylinders, and install oversize pistons. Before boring, install main bearing caps and tighten bolts to specification to prevent cylinder distortion.
3. Standard diameter of cylinder bores may differ from cylinder to cylinder. Cylinder bore grade number on cylinder block deck surface, next to each cylinder bore, represents standard diameter of cylinder. If installing standard diameter pistons, ensure grade number on top of piston matches cylinder bore grade number.
