Key Features:
Robust construction, powerful engine options, advanced hydraulic system for its time, optional Power-Shift transmission, comfortable operator station, a wide range of factory and dealer-installed implements.
Systems Covered:
Engine (gasoline, diesel variants), transmission (manual and power-shift), hydraulic system (lift, draft control, remote hydraulics), electrical system (charging, ignition, lighting), steering system, braking system, front axle, rear axle, PTO (Power Take-Off), hitch system, sheet metal, operator controls.
Procedures Included:
Engine tune-up, carburetor adjustment, injection pump timing, cylinder head removal/installation, piston and connecting rod service, crankshaft inspection, transmission gear removal/installation, clutch service, hydraulic pump rebuilding, cylinder seal replacement, electrical component testing and replacement, brake adjustment and repair, front and rear axle overhaul, PTO clutch service, routine maintenance procedures, troubleshooting guides for common problems, torque specifications, diagnostic flowcharts.
Technical Depth:
Comprehensive, covering everything from basic maintenance and adjustments to complete engine, transmission, and hydraulic system overhauls. Includes detailed diagrams, exploded views, and step-by-step instructions.
Engine Options:
Gasoline: Allis-Chalmers 262ci (4.3L) 4-cylinder. Diesel: Allis-Chalmers 262ci (4.3L) 4-cylinder (various configurations, including turbocharger option for some models, although primarily associated with D19/200). The D-17 Series IV typically featured the naturally aspirated 262ci diesel.

Standard Transmission:
Constant mesh, sliding gear transmission with 6 forward speeds and 2 reverse speeds.
Optional Transmission:
Allis-Chalmers Power-Director (two-speed power shift unit for each gear, effectively doubling speeds to 12 forward and 4 reverse).
Clutch Type:
Single dry-plate or dual-plate clutch (depending on PTO option).
Transmission Fluid Type:
Refer to manual for specific fluid, typically API GL-4 rated gear oil for transmission/differential and AC Type 'U' or equivalent hydraulic fluid for hydraulic system.
Safety Features Design:
While not subject to modern tractor ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) standards, the D-17 Series IV was designed with operator safety in mind for its era. The manual will cover brake system functionality and proper operation.
Active Safety Systems:
Effective braking system, secure steering, operator presence lever (clutch safety switch on some models).
Passive Safety Features:
Operator station, lighting for visibility (if equipped).
Engine Oil Change Interval:
Every 50 hours of operation or annually, whichever comes first (typical for the era).
Fuel Filter Replacement:
As needed, or every 250 hours (diesel).
Transmission Fluid Change:
Refer to manual, typically every 500-1000 hours.
Engine Oil Specification:
SAE 30W or 10W-30 depending on ambient temperature. Refer to manual for exact API service classification (e.g., API CC/CD for diesel, API SF/SE for gasoline).
Hydraulic Fluid Specification:
Allis-Chalmers Type 'U' Hydraulic Oil or equivalent universal tractor transmission fluid (UTTF) with good anti-wear properties.
Transmission Gear Oil:
API GL-4 rated gear oil.
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors, typically a 50/50 mix with water.
Common Issues:
Hydraulic system leaks (worn seals, hoses), carburetor issues (gumming, adjustment), injection pump timing drift (diesel), PTO clutch wear, brake fade, starter motor problems, electrical wiring degradation over time.
Troubleshooting Approach:
The manual provides systematic troubleshooting steps for engine starting problems, power loss, hydraulic system malfunctions, and transmission engagement issues, crucial for diagnosing and repairing common faults.
Brand Heritage:
Allis-Chalmers was a prominent American manufacturer of agricultural and industrial machinery, known for its innovation and robust product line from the early 20th century until its acquisition in 1985.
Model Evolution:
The D-17 was first introduced in 1957, evolving through several series. The Series IV, produced from 1965 to 1967, represented a refinement of the D-17, often featuring updated styling, improved hydraulics, and the introduction of the Power-Director transmission as a key option.
Production Years:
1965-1967 (Series IV)
Manufacturing Location:
Galesburg, Illinois, USA
