Air Conditioner Support Bracket - Remove and Install SMCS - 1802-010

Removal Procedure

Illustration 1

g01064408

1. Remove bolts (1) with the nuts and the washers. 2. Remove bolts (2) and the washers. 3. Remove air conditioner compressor support bracket (3) .

Installation Procedure NOTICE The air conditioner support bracket provides additional support for the mounting pad on the engine front housing. However, due to the increased stiffness of this bracket, extra care is needed when installing the air conditioner compressor support bracket on the engine. Following the correct installation procedure will avoid applying assembly stresses to the engine front housing mounting pad which may lead to a crack.

Illustration 2

g01064408

1. Install air conditioner support bracket (3) with the following procedure. a. Install bolts (1) with the nuts and the washers. Finger tighten the bolts. b. Install bolts (2) and the washers. Finger tighten the bolts.

NOTICE Ensure that there is no gap between the air conditioner compressor support bracket and the engine front housing. Ensure that there is no gap between the air conditioner support bracket and the cylinder head. Reposition the air conditioner compressor support bracket in order to eliminate the gap.

c. Lightly tighten bolts (1) and bolts (2) . d. Ensure that air conditioner support bracket (3) remains tight against the engine front housing and the cylinder head. e. Tighten the bolts to a torque of 47 ± 9 N·m (35 ± 7 lb ft). Copyright 1993 - 2024 Caterpillar Inc. All Rights Reserved. Private Network For SIS Licensees.

Alternator - Remove and Install SMCS - 1405-010

Removal Procedure

Personal injury can result from failure to disconnect the battery. First, disconnect the negative battery cable. Then, disconnect the positive battery cable. A positive power lead can cause sparks if the battery is not disconnected. Sparks can possibly result in battery explosion or fire.

1. Remove the drive belt from the drive pulley on the alternator. 2. Place an index mark on all of the harness assemblies that are connected to the alternator. Disconnect the harness assemblies from the alternator.

Illustration 1

3. Remove bolt (1) . 4. Remove nut (2) and the bolt from mounting bracket (3) . 5. Remove alternator (4) .

Installation Procedure

g01028740

Illustration 2

g01028740

1. Position alternator (4) on mounting bracket (3). Install the bolt and nut (2). Hand tighten nut (2) . 2. Install bolt (1). Do not tighten. 3. Install the drive belt on the drive pulley of the alternator. 4. Adjust the tension on the drive belt. Refer to the Operation and Maintenance Manual for the correct adjusting procedure. 5. Tighten bolt (1) . 6. Tighten nut (2) . 7. Connect all harness assemblies to the alternator. Use the index marks to correctly connect the harness assemblies. Copyright 1993 - 2024 Caterpillar Inc.

Bearing Clearance - Check SMCS - 1203-535; 1219-535

Measurement Procedure Table 1 Required Tools Tool

Part Number

Part Description

Qty

198-9142

Plastic Gauge (Green) 0.025 to 0.076 mm (0.001 to 0.003 inch)

198-9143

Plastic Gauge (Red) 0.051 to 0.152 mm (0.002 to 0.006 inch)

198-9144

Plastic Gauge (Blue) 0.102 to 0.229 mm (0.004 to 0.009 inch)

198-9145

Plastic Gauge (Yellow) 0.230 to 0.510 mm (0.009 to 0.020 inch)

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.

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 - 2024 Caterpillar Inc.

1. Install Tooling (A) . Note: Ensure that camshaft (2) and Tooling (A) are clean. Apply clean engine oil to the lobes and journals of camshaft (2) and Tooling (A) . Note: During installation of camshaft (2), rotate the camshaft in both directions in order to prevent binding in the camshaft bearing bores. 2. Carefully install camshaft (2) in the engine.

NOTICE When installing the camshaft, make sure the number one cylinder is at top center of the compression stroke with the 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.

3. Ensure that the timing marks (3) on the idler gear are aligned with the timing marks on the crankshaft gear and the camshaft drive gear. 4. Install thrust pin (1). Tighten thrust pin (1) to a torque of 28 ± 7 N·m (20 ± 5 lb ft). Remove the wires that were used to hold the valve lifters. End By: a. Install the camshaft position sensor. Refer to Disassembly and Assembly, "Camshaft Position Sensor Remove and Install". b. Install the front cover. Refer to Disassembly and Assembly, "Front Cover - Install".

c. Install the rocker shaft and the pushrods. Refer to Disassembly and Assembly, "Rocker Shaft and Pushrod - Install". Copyright 1993 - 2024 Caterpillar Inc. All Rights Reserved. Private Network For SIS Licensees.
