Standard rear differential lock, foot or hand operated
Engine Oil Change:
Typically every 100-150 operating hours, or annually. Specific recommendation in manual.
Air Filter Service:
Check/clean every 50 hours, replace as needed. Follow specific instructions for oil-bath or dry type filters.
Fuel Filter Change:
Replace annually or every 250 hours, or as indicated by fuel system performance.
Hydraulic Fluid Change:
Typically every 500-1000 operating hours, or annually. Filter replacement also crucial.
Engine Oil Viscosity:
SAE 30 or 10W-30 Diesel engine oil (API CD or equivalent). Check manual for specific grade based on temperature.
Hydraulic Fluid Type:

Transmission Fluid Type:
Gear oil (e.g., SAE 80W-90) for manual transmission, and UTF/hydraulic fluid for power director and final drives. Manual is critical for correct application.
Common Wear Items:
Clutch wear, PTO clutch engagement issues, hydraulic pump wear, injector pump calibration, steering box wear, electrical connections.
Potential Failures:
Overheating (due to cooling system maintenance), fuel system blockages, electrical wiring degradation, seal leaks in hydraulics and transmission.
Importance Of Manual:
Strict adherence to the manual's lubrication schedule and component inspection routines is vital for preventing costly repairs.
Brand Context:
Allis-Chalmers was a prominent American manufacturer of agricultural, construction, and industrial machinery from the early 20th century until its acquisition by Deutz-Allis in 1985.
D Series Lineage:
The D-17 was part of Allis-Chalmers' successful 'D' series tractors, known for their distinctive 'Allis-Orange' paint scheme and robust engineering. The Series IV represented the final iteration with various refinements.
Production Years:
The D-17 was produced from 1957 to 1967. The Series IV typically covers the later years of this production run.
Manufacturing Location:
Harvey, Illinois, USA
Tractor Acclaim:
The D-17 Series IV was a highly regarded tractor in its era, known for its durability, power, and versatility in agricultural applications.
Diagnostic Tools Availability:
While not a 'technology' feature, the manual's detailed diagnostic procedures and specifications are the primary 'tools' for understanding and repairing the tractor.
