19. Note: Cat does not recommend the checking of the actual bearing clearances particularly on small
engines. This is because of the possibility of obtaining inaccurate results and 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 points of 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

parts of Tooling (A) are not the same width. Measure the major width in order to ensure that
the parts are within the specification range. Refer to Specifications Manual, "Connecting
Rod Bearing Journal" and Specifications Manual, "Main Bearing Journal" for the correct
clearances.
