1970-1975 Allis Chalmers Model 160 Tractor Shop Manual (P/N AC-160-SM)

• Covers the 1970–1975 Allis Chalmers Model 160 tractor equipped with the Perkins AD 3.152 diesel engine and 10-speed dual-range transmission
• Original OEM publication P/N AC-160-SM, Shop Manual for Allis Chalmers Model 160, published circa 1970
• Contains 146 figures. Includes detailed exploded-view diagrams of the power steering, hydraulic lift system, transmission gear trains, and electrical wiring
• 51 pages of technical schematics and factory-recommended clearance values for engine and chassis systems
• Provides the factory-specified torque values and tolerance charts required for the 160 series rebuild and maintenance

Mechanical and Systems Documentation

This manual details the complete mechanical layout of the 1970–1975 Allis Chalmers Model 160. It breaks down heavy jobs. You get a clear look at the procedures for splitting the tractor, overhauling the diesel fuel system, and servicing the hydrostatic steering gear. Major chapters map out the timing gear housing, camshaft, and valve train configurations, alongside the dual-range transmission assembly. The text provides a direct path for component inspection on the rear axle and differential lock mechanisms.

Later chapters break down the hydraulic lift system. You will see exactly how the lift arm control valve and draft sensing linkages operate. Technical depth is high for the Perkins AD 3.152 engine. It covers critical areas like timing specifications and piston ring assembly. The entire document is indexed by starting paragraph. This makes jumping between engine, steering, hydraulic, and electrical system diagnostics fast and efficient on the workbench.

Specification and Reference Data

Technical specifications are categorized for quick shop reference. The tables list exact tolerances for crankshaft journals, valve guides, and cylinder liners. You will find critical fastener specs directly. Cylinder head nuts take 55–60 Ft.-Lbs. of torque. Main bearing cap screws require 110–115 Ft.-Lbs. Cooling system capacity sits at 8 quarts. For the hydraulics, relief valve pressure is set at 2300–2400 PSI. The tune-up data table lists intake valve clearance at 0.010 hot or 0.012 cold.

Always prioritize shop safety. Heavy mechanical work demands following proper procedures and relying on authoritative factory data to prevent injury or equipment failure during a teardown.
