Dodge Ram 1500/2500/3500 1995–2001 Service Manual (P/N 81-370-5108)

This PDF reproduces Chrysler Corporation’s factory service manual for the 1995 Dodge Ram 1500, 2500, and 3500, P/N 81-370-5108. It covers whole-vehicle service for the BR truck family, including 2WD and 4WD pickups and cab-chassis configurations, regular/conventional and Club Cab bodies, and single- or dual-rear-wheel applications where specified.

PDF Search, Chapter Bookmarks, and Diagram Detail

Search and drawing access: An embedded OCR text layer supports searches across the service chapters, but some illustrated pages and drawing labels are not searchable. The PDF has 38 bookmarks covering the main groups and electrical subsections. Small wiring codes, connector numbers, and dense schematic labels require zooming.

The download contains one printable PDF with 1,794 pages, including the original cover and 36 blank separator pages.

Powertrain, Chassis, and Electrical Repair

The following selected coverage highlights summarize part of the manual. Additional topics include snowplow hydraulic and electrical service and trailer-towing specifications.

• Engine and fuel systems: Step-by-step engine removal and installation, cylinder-head and valvetrain service, timing-drive and lubrication repair, gasoline multi-port injection tests, and Cummins injection-pump timing, transfer-pump, injector, intake-heater, and water-separator diagnosis.

• Transmissions and four-wheel drive: NV3500 and NV4500 disassembly, inspection, assembly, and adjustment; 42RH/46RH/47RH hydraulic diagnosis and overhaul; overdrive-unit repair; and NP231 HD/NP241/NP241 HD transfer-case service.

• Axles, suspension, and steering: IFS and link/coil suspension, alignment, Model 44/60 front axles, 9-1/4-inch and Model 60/70/80 rear axles, Trac-Lok/Power-Lok differentials, propeller-shaft vibration diagnosis, power-steering pressure testing, and recirculating-ball steering-gear repair.

• Brakes and clutch: Front disc and rear drum service, master-cylinder overhaul and bench bleeding, booster and diesel vacuum-pump tests, parking brakes, RWAL and optional all-wheel ABS diagnosis, hydraulic bleeding, and clutch troubleshooting.

• Electrical systems: Battery, starting, charging, and ignition tests; PCM inputs and outputs; airbag diagnosis; instruments, speed control, and power accessories; plus system wiring diagrams.

• Cooling, HVAC, and body: Cooling-system pressure tests, R-134a refrigerant service, A/C performance and vacuum-control tests, body repair, urethane-set glass replacement, and water-leak and wind-noise diagnosis.

The material suits technicians and experienced owners who understand automotive systems and have lifting equipment, precision measuring tools, electrical test equipment, and the specified service tools. It assumes workshop knowledge rather than teaching automotive repair from the beginning; refrigerant work is expressly reserved for qualified service personnel.

Gasoline and Cummins Engine Detail

Engine identification: Gasoline sections cover the 3.9L V6, 5.2L V8, 5.9L V8, and 8.0L V10. The diesel section covers the turbocharged 5.9L Cummins inline-six. The eighth VIN character identifies these engines as X, Y, Z/5, W, and C respectively, with separate Z and 5 designations for the 5.9L LDC and HDC gasoline versions.

The fuel and emissions chapters distinguish light-duty-cycle and heavy-duty-cycle systems. Engine-driven air injection applies to the HDC gasoline configurations, so those procedures should not be treated as interchangeable with the LDC sections.

Diesel repair depth: Cummins coverage extends to cylinder-head, piston and connecting-rod, crankshaft, camshaft, gear-housing, and lubrication-system work, along with valve-clearance adjustment. Turbocharger removal, installation, and wastegate checks are included; internal turbocharger repair is directed to an authorized facility.

Transmission Applications and PTO Service

The NV3500 section covers 3.9L and 5.2L installations. NV4500 coverage distinguishes standard-duty 5.2L/5.9L applications from heavy-duty V10/Cummins applications, including their shaft differences and shared overhaul procedures. Clutch coverage also includes NV4500 clutch-housing runout checks.

The automatic-transmission chapters separate the 42RH application in 3.9L 4x2 1500 trucks, gasoline V6/V8 applications using the 46RH, and V10/Cummins applications using the 47RH.

NP231 HD, NP241, and NP241 HD procedures cover removal through reassembly. Their internal parts are not interchangeable despite similar overhaul procedures. The optional NV 021 PTO adapter has its own diagnosis, removal, overhaul, installation, and linkage-adjustment section for applicable 2WD 2500/3500 automatic-transmission trucks.

Fault Isolation, Schematics, and Service Tools

Diagnostic support: Axle-noise and driveline-snap charts accompany the mechanical procedures. Automatic-transmission road-test analysis, clutch-and-band application charts, hydraulic-pressure tests, stall tests, and air tests help distinguish possible internal faults before teardown.

Gasoline and diesel DTC descriptions and component tests are included. DRB operation and some PCM circuit tests require the separate Powertrain Diagnostic Procedures manual, which is referenced by this book.

Drawing examples: Gasoline and diesel fuel/ignition circuits, transmission-control schematics, RWAL and all-wheel ABS circuits, transfer-case exploded views, vacuum-hose routing diagrams, and connector pin-out/location drawings support diagnosis and assembly identification.

Tool references include terminal-release tool 6742, probing package 6807, IAC motor exerciser 7558, cylinder-bore indicator 6879, propeller-shaft angle tool 7663, steering-wheel puller C-3428B, and A/C Tool Kit 6125.

Workshop Specifications and Component Precautions

The service data includes component torque tables, fluid capacities, alignment settings, pressure-test specifications, electrical resistance and voltage values, bearing preload, end play, gear backlash, wear limits, and transmission adjustments. Separate light-duty, heavy-duty, and diesel maintenance schedules identify the corresponding inspection and fluid-service requirements.

The suspension sections explain how tightening rubber-bushed components away from normal ride height can cause premature bushing wear. Axle-service cautions also address bearing-surface damage caused by spinning cleaned bearings with compressed air.

Use suitable lifting and support equipment for heavy assemblies, and observe the manual’s airbag isolation and refrigerant recovery precautions.

A Preview of Cummins Valve-Clearance Data

For the 5.9L Cummins diesel, the valve-adjustment section specifies intake clearance of 0.254 mm (0.010 in.) and exhaust clearance of 0.508 mm (0.020 in.), with the engine cold and below 60°C (140°F). Timing-pin illustrations and valve-position diagrams accompany the adjustment procedures.
