Komatsu D32E-1 / D32P-1 / D38E-1 / D38P-1 / D39E-1 / D39P-1 Bulldozer Shop Manual

This 629-page factory documentation serves as the primary reference for 1990–1997 Komatsu D32E-1 through D39P-1 bulldozers. It delivers critical clearance, fluid, and pressure data directly to your workbench, helping you accurately assess drivetrain and cooling system conditions. Because heavy machinery maintenance inherently involves high pressures, heavy loads, and crushing hazards, always rely on authoritative OEM specifications and observe proper shop safety protocols before initiating any hands-on work or diagnostic tests.

• Covers D32E-1, D32P-1, D38E-1, D38P-1, D39E-1, and D39P-1 models
• Identified by official Komatsu publication form number CEBM000301 (March 1997)
• Applies to serial numbers starting at P075501 (D32 series), P085501 (D38 series), and P095501 (D39 series)
• Includes 51 detailed exploded-view diagrams mapping out radiator, torque converter, and rear housing assemblies

Component and System Overview

When you have a machine down in the bay, you need fast access to reliable teardown logic. This text outlines the complete disassembly and rebuild sequence for vital cooling systems, walking through radiator core and tank refurbishment. You will find detailed power flow charts mapping the drivetrain from the engine flex plate straight through the torque converter, steering drive, and transmission. Diagnostics get easier, too. The material covers exact procedures for setting up external gauges to verify stall speeds and run pressure tests. Need to evaluate track wear? It also details undercarriage service, specifying exact pin and bushing alignment tolerances to help you make the right call on replacements.

Technical Data and Specifications

Guessing bolt tightness leads to comebacks. This reference eliminates that risk by supplying comprehensive torque values for standard bolts ranging from 8-32 to 1-3/4 inches, alongside metric fasteners from M6 to M39. Fluid capacity charts clearly separate coolant, engine oil, and hydraulic system requirements across all three machine series. You get baseline reference pressures for transmission lubrication and torque converter circuits during both neutral and stall conditions. Furthermore, the text lists explicit component clearances and mounting torques for final drives, engine blocks, and cooling assemblies.
