Installation Procedure Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. Note: Check the O-ring seals, the gaskets, and the seals for wear or for damage. Replace the components, if necessary.

Note: Plastic gauge may not be necessary when the engine is in the chassis.

NOTICE Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.


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 1.


Illustration 1

g01152855

Typical Example

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 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. Copyright 1993 - 2025 Caterpillar Inc.

Camshaft - Remove and Install SMCS - 1210-010

Removal Procedure Start By: a. Remove the front housing. Refer to Disassembly and Assembly, " Housing (Front) Remove". b. Remove the rocker shaft assembly and the pushrods. Refer to Disassembly and Assembly, "Rocker Shaft and Pushrod - Remove". c. Remove the oil pan. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install". Note: In this removal procedure, the engine needs to be placed in the upside-down position. This will allow the lifters to remain in position after the camshaft is removed.

NOTICE Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.

NOTICE Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers


before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products. Dispose of all fluids according to local regulations and mandates.
