NOTE: Cracks can also be detected by using either mag- netic inspection or the dye method. Replace the liner if cracks are found in the flange area. Visually inspect the exterior of the liners. Hot steam can cause serious personal injury. Page Inspection If pistons are unacceptable for reuse, do not use the mating piston pins.
Cummins recommends replacing pistons and pins in sets. Visually inspect the piston ring lands and ring grooves for wear. Piston Pin Bore Page Inspection Connecting Rod Assemblies - Cleaning and Inspection Cylinder Block Page Inspection Visually inspect the connecting rod and the cap for fret- ting damage on the mating surfaces.
The rod and the cap must be replaced as an assembly if any fretting damage is visible on either piece. Visually inspect under the capscrew heads for cracks. Measure the capscrew outside diameters.

Move the dial holder to position the contact points of the indicators on the mandrel in the piston pin bore. Tighten the bracket to hold the indicators in position. Connecting Rod Length Page Connecting Rod Bearings - Cleaning and Inspection Cylinder Block Page NOTE: If large areas of copper lining are visible in the bear- ings before the engine has accumulated , kilometers [, miles] or 3, hours, inspect the engine for con- tamination from fine dirt particles; Also, the wire brush must be rated for the RPM being used if the brush is motor driven.
Use an emery cloth or a steel wire brush. Outside Pilot Diameter Spun Steel Crankshaft Pulley I. Personal injury can result. ST, and solvent to clean all the oil drillings. Warning: When using a steam cleaner, wear protective clothing and safety glasses or a face shield. Visually inspect the crankshaft gear for cracks and broken or chipped teeth. Where the front and the rear crankshaft seals contact the crankshaft, the maximum allowable wear is 0.
Crankshaft Main Bearing Journal O. Crankshaft Thrust Face Width Install the puller jaw and the bridge assembly. Use engine oil to lubricate the puller jackscrew. Page Crankshaft Gear - Replacement Cylinder Block Page Visually inspect the crankshaft gear fit area for burrs or damage. Use a fine crocus cloth to remove the burrs. Inspection Visually inspect the crankshaft gear for cracks and broken or chipped teeth.
Visually inspect the gear and the keyway for nicks or burrs. Crankshaft Gear Fit Area O. Use Lubriplate No. Caution: The timing mark 1 and the part number 2 on the gear must be facing away from the crankshaft after the gear is installed. Bearing shells are identified by steel stamped characters on the back of the bearings to indicate either standard or the amount of oversize.
Page 40 oil before handling. Inspection Visually inspect the valve and injector lobes for damage. If the camshaft is damaged, it must be replaced. Camshaft Bushing Journal O. Measure the camshaft thrust washer. Camshaft Thrust Washer Thickness 2. If you use a heating torch, a new gear must be installed. Push the shaft from the gear. NOTE: If the camshaft key is marked with an arrow, record the direction the arrow on the key is pointed toward or away from the camshaft for future reference.
Camshaft Gear Bore I. Flangeless Caution: If the area of fretting is longer than a 3. Remove the gear from the oven. Caution: The aluminum gasket surface can be easily damaged if caution is not used when removing gasket material. An oil leak will result. Use a gasket scraper to remove all gasket material. Accessory Drive Seal Bore I. Measure the crankshaft seal bore.
Accessory Drive Bushing Bore I. Use gear cover bushing mandrel, Part No. Use solvent to clean the rear cover. Dry with compressed air. Inspection Inspect the rear cover for cracks or other damage. Measure the rear cover crankshaft seal bore. ST Injector Sleeve Expander Roll and seal the upper portion of the injector sleeve in the cylinder head. Tool Description Tool Illustration Injector Sleeve Holding Tool Hold the injector sleeve in place when rolling the upper portion of the sleeve and testing the cylinder head.
Page Cylinder Head - General Information Cylinder Head Cylinder Head - General Information Page Cylinder Head - General Information The cylinder head group consists of the cylinder head, valves, valve guides, valve springs, stem seals, valve seat inserts, cylinder head capscrews, fuel crossover, collets, spring retainer, crossheads, and the injector sleeves. The exhaust valves are manufactured from a material that is capable of operating at a higher temperature than the intake valves.
Blow out all capscrew holes, fuel passages, and oil passages. Inspection Visually inspect the fuel drillings and the water passages for restrictions or foreign material. Remove any obstructions. Visually inspect the valves and the valve springs for cracks, bent or broken valve stems, broken valve springs, or other damage. Visually inspect the valves for indications of leakage or burning.
Discard the valve collets. Slowly release the pressure on the valve spring. Remove the valve spring retainer. Remove the valve spring s. Remove the valve stem seal. Remove the valves. Install the cylinder head and the parts in a tank of clean- ing solution. Remove the cylinder head and parts from the cleaning tank. Flatness Per Limit NOTE: Install the valve on the tool with the valve head contacting the tool as shown. If the valve head is even with, or extends beyond the end of the tool, the valve can be reground.
Valve Seat Area Width 1. Page Grinding The Valve Seats Cylinder Head Cylinder Head - Rebuild Page Remove the injectors from the cylinder head and check the pattern of the blueing compound in the injector sleeve. The blueing pattern in the injector seating area 1 must be visible degrees around the seating area.
The injector bore seating width 2 must be a minimum of 1. Page Cylinder Head - Rebuild Cylinder Head Page Hold the drive unit in a vertical position, and use an up-and-down movement of Remove the grinder unit from the arbor.
