Updated -11/02/2015
Keep all parts clean from contaminants.
Contaminants may cause rapid wear andshortened component life.
Note: Cat does not recommend the checking of the actual bearing clearancesparticularly on small engines. This is because of the possibility of obtaining inaccurate resultsand the possibility of damaging the bearing or the journal surfaces. Each Cat engine bearing is quality checked for specific wall thickness.
Note: The measurements should be within specifications and the correct bearings should be used. If the crankshaft journals and the bores for the block and the rods were measured during disassembly, no further checks are necessary. However, if the technician still wants to measure the bearing clearances, Tooling (A) is an acceptable method. Tooling (A) is less accurate on journals with small diameters if clearances are less than 0.10 mm (0.004 inch).
NOTICE
Lead wire, shim stock or a dial bore gauge can damage the bearing surfaces.
The technician must be very careful to use Tooling (A) correctly. The following points must be remembered:
• Ensure that the backs of the bearings and the bores are clean and dry.
• Ensure that the bearing locking tabs are properly seated in the tab grooves.
• The crankshaft must be free of oil at the contact pointsof Tooling (A).
1. Put a piece of Tooling (A) on the crown of the bearing that is in the cap.
Note: Do not allow Tooling (A) to extend over the edge of the bearing.
2. Use the correct torque-turn specifications in order to install the bearing cap. Do not use an impact wrench. Be careful not to dislodge the bearing when the cap is installed.
Note: Do not turn the crankshaft when Tooling (A) is installed.
3. Carefully remove the cap, but do not remove Tooling (A). Measure the width of Tooling (A) while Tooling (A) is in the bearing cap or on the crankshaft journal. Refer to Illustration 1.
Illustration 1 g01152855
TypicalExample
4. Remove all of Tooling (A) before you install the bearing cap.
Note: When Tooling (A) is used, the readings can sometimes be unclear. For example, all partsof Tooling (A) are not the same width. Measure the major width in order to ensure that the partsare within the specification range. Refer to Specifications Manual, "Connecting Rod Bearing Journal" and SpecificationsManual, "Main Bearing Journal" for the correct clearances.

NOTICE
Do not damage the lobesor the bearings when the camshaft is removed or installed.
Note: During the installation of the camshaft, rotate the camshaft in both directions in order to prevent binding in the camshaft bearing bores.
1. Lubricate the camshaft lobes and the valve lifter bore with a 50/50 mixture of Tooling (B). Apply clean engine oil on the camshaft bearing journals. Carefully install camshaft (10) in the cylinder block.

g03356207
NOTICE
When installing the camshaft, make sure the number one cylinder isat top center of the compression stroke withthe timing bolt installed in the flywheel. The camshaft timing is very important. The timing mark on the camshaft drive gear must line up with the timing mark on the idler gear. Refer to the Specifications Manual for more information.
2. Correct fuel injection timing and correct valve mechanism operation is determined by properly timing crankshaft gear (8) and camshaft gear (6) to idler gear (7). Also, high-pressure fuel pump gear (5) must be timed to camshaft gear (6). During installation of the front gear, timing marks (9) on idler gear (7)
must be in alignment with the timing marks on crankshaft gear (8) and the timing marks on camshaft gear (6). The "0" mark on camshaft gear (6) must align with the timing mark on idler gear (7). The "V" mark on camshaft gear (6) must align with the "V" mark on fuel pump gear (5).
Illustration 3 g01032348
3. Install thrust plate (4) and bolts (3).
4. The maximum permissible end play for a worn camshaft is0.46 mm (0.018 inch). The maximum permissible end play for a new camshaft is0.13 ± 0.08 mm (0.005 ± 0.003 inch).
5. Use Tooling (A) to position the valve liftersin the cylinder block.
6. Calibrate the speed/timing sensor. Refer to Troubleshooting, "Engine Speed/Timing SensorCalibrate".
End By:
a. Install the front cover. Refer to Disassembly and Assembly, "Front Cover - Install".
b. Install the rocker arm and the shaft. Refer to Disassembly and Assembly, "Rocker Arm and ShaftInstall".
