SPECIAL TOOL(S) SPECIFICATION Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) or equivalent

1. Use a Dial Indicator Gauge with Holding Fixture to measure the camshaft runout. Rotate the camshaft and subtract the lowest indicator reading from the highest indicator reading. For additional information, refer to the specification chart in the appropriate ENGINE MECHANICAL article. If out of specification, install new components as necessary. Refer to the appropriate ENGINE MECHANICAL article for the procedure.

Scheme 715

1. Measure each of the crankshaft main bearing journal diameters in at least 2 directions. Refer to the appropriate Engine Mechanical article for the procedure. If out of specification, install new components as necessary. Refer to the appropriate Engine Mechanical article for the procedure.

Scheme 716

1. Measure each of the crankshaft main bearing journal diameters in at least 2 directions at each end of the main bearing journal. Refer to the appropriate Engine Mechanical article for the procedure. If out of specification, install new components as necessary. Refer to the appropriate Engine Mechanical article for the procedure.

SPECIAL TOOL(S) SPECIFICATION Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) or equivalent

Scheme 717

1. Use a Dial Indicator Gauge with Holding Fixture to measure crankshaft end play.
2. Position the crankshaft to the rear of the cylinder block.
3. Zero the indicator.
4. Move the crankshaft to the front of the cylinder block. Note and record the crankshaft end play. If crankshaft end play exceeds specifications, install a new crankshaft thrust washer or crankshaft thrust main bearing. Refer to the appropriate ENGINE MECHANICAL article for the procedure.

SPECIAL TOOL(S) SPECIFICATION Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) or equivalent

1. Use the Dial Indicator Gauge with Holding Fixture to measure the crankshaft runout. Refer to the appropriate ENGINE MECHANICAL article for the procedure. Rotate the crankshaft and subtract the lowest dial indicator reading from the highest dial indicator reading to figure the crankshaft runout. If it is out of specification, install new components as necessary. Refer to the appropriate ENGINE MECHANICAL article for the procedure.

SPECIAL TOOL(S) SPECIFICATION Scraper, Piston Ring Groove 303-D033 (D81L-6002-D) or equivalent

Scheme 718

Scheme 719

Scheme 720

1. Clean and inspect the (1) ring lands, (2) skirts, (3) pin bosses and the (4) tops of the pistons. If wear marks, scores or glazing is found on the piston skirt, check for a bent or twisted connecting rod.
2. Use the Piston Ring Groove Scraper to clean the piston ring grooves. Make sure the oil ring holes are clean.

SPECIAL TOOL(S) SPECIFICATION Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) or equivalent Clearance Gauge, Valve Guide 303-004 (TOOL-6505-E) or equivalent

Note. Valve stem diameter must be within specifications before checking valve stem to valve guide clearance.

1. Install a Valve Guide Clearance Gauge on the valve stem and install a Dial Indicator Gauge with Holding Fixture. Lower the valve until the Valve Guide Clearance Gauge contacts the upper surface of the valve guide.
2. Move the Valve Guide Clearance Gauge toward the indicator and zero the indicator. Move the Valve Guide Clearance Gauge away from the indicator and note the reading. The reading will be DOUBLE the valve stem-to-valve guide clearance. Valves with oversize stems will need to be installed if out of specification.

Scheme 721

1. Inspect the following valve areas: The end of the stem for grooves or scoring. The valve face and the edge for pits, grooves or scores. The valve head for signs of burning, erosion, warpage and cracking. The valve margin for wear.

Scheme 722

1. Use a ball gauge to determine the inner diameter of the valve guides in 2 directions at the top, middle and bottom of the valve guide.
2. Measure the ball gauge with a micrometer. Refer to the appropriate ENGINE MECHANICAL article for the specification.
3. If the valve guide is not within specifications, ream the valve guide and install a valve with an oversize stem or remove the valve guide and install a new valve guide.

Scheme 723

1. Use a hand-reaming kit to ream the valve guide.
2. Reface the valve seat.
3. Clean the sharp edges left by reaming.

Scheme 724

1. Measure the installed length of each valve spring. Refer to the appropriate ENGINE MECHANICAL article for the procedure. If out of specification, install new components. Refer to the appropriate ENGINE MECHANICAL article for the procedure.
