Engine Family Overview:
These models typically feature robust, multi-cylinder diesel engines manufactured by Allis-Chalmers, with some variants potentially offering gasoline options. Specific engine families include the 149, 175, and 201 series diesel engines, and potentially Waukesha or Continental gasoline engines for earlier or specific models.
Horsepower Range:
Horsepower ratings vary by model and engine configuration, generally ranging from approximately 60 HP to over 100 HP.
Torque Characteristics:
Engines are designed for strong low-end torque, essential for agricultural applications, with specific torque figures detailed in the manual.
Diesel Injection:
Typically utilize Roosa Master or similar rotary or inline injection pumps. The manual covers pump timing, rebuilding, and injector servicing.
Turbocharger:
Models like the 190XT and 7000 often feature turbochargers. The manual provides specific service procedures for turbocharger maintenance, including lubrication and sealing.
Engine Oil Change:
Typically every 100-200 operating hours, depending on operating conditions. Manual will specify exact intervals and oil types.
Hydraulic Fluid Change:
Recommended at intervals such as every 600-1200 operating hours. Manual will specify fluid type (e.g., Hy-Trans or equivalent) and capacity.
Fuel Filter Replacement:
Typically every 250-500 operating hours or as needed for diesel fuel systems. Manual will provide specific part numbers and procedures.
Engine Oil Viscosity:
Commonly 15W-30 or 20W-40 for diesel engines, depending on ambient temperature. Manual will confirm exact specifications.
Transmission Hydraulic Fluid:
Allis-Chalmers Hy-Trans or equivalent UTF (Universal Tractor Transmission Fluid) meeting specific friction and viscosity requirements. Capacities typically range from 10-15 gallons.
Coolant Type:
Ethylene glycol based antifreeze mixed with distilled water, typically a 50/50 ratio for freeze protection and corrosion inhibition. Manual will specify coolant type and capacity.
Hydraulic Leaks:
Commonly found issues include worn hydraulic pump seals, cylinder seal leaks, and control valve spool wear, all detailed in the manual's troubleshooting section.
Transmission Wear:
Over time, clutch packs in Power-Director transmissions and gear wear in standard transmissions can occur. The manual provides guidance on inspection and replacement.
Diesel Injection Problems:
Routine maintenance of the fuel filter and occasional adjustment or rebuild of the injection pump are essential to prevent issues like hard starting or rough running.
