Engine Manufacturer:
Allis-Chalmers
Engine Model:
Based on the 7000 series, likely a diesel engine, specific model designation would be within the manual.
Engine Type:
Typically a naturally aspirated or turbocharged diesel engine, known for durability.
Displacement:
Varies by specific engine variant, but typically in the range of 400-500 cubic inches (6.5-8.2 liters) for this class of tractor.
Horsepower Range:
Likely in the 100-150 PTO horsepower range, subject to specific engine configuration.
Torque:
High torque output for pulling power, specific figures depend on engine variant.
Injection System:
Typically direct injection, using Bosch or similar quality fuel injection pumps.
Wheelbase:
Varies, but typical for a tractor of this class, designed for stability.
Operating Weight:
Substantial, designed for traction and stability, likely in the 10,000-15,000 lb (4,500-6,800 kg) range.
Infotainment System:
Basic, focused on operational function rather than entertainment. May include a radio as an option.
Driver Assistance Features:
Limited to operational aids like power steering and potentially PTO engagement controls.
Connectivity Features:
None in the modern sense; mechanical and electrical connections for implements.
Engine Oil Change:
Typically every 250-500 operating hours, detailed in the manual.
Transmission Fluid Change:
Manufacturer recommended intervals, often annually or based on operating hours.
Engine Oil:
API CD or CE rated diesel engine oil, SAE 15W-40 or SAE 30, specific viscosity depends on ambient temperature (detailed in manual).
Hydraulic Fluid:
Tractor hydraulic fluid (THF) meeting Allis-Chalmers specifications, or equivalent Universal Tractor Transmission Oil (UTTO).
Transmission Fluid:
Refer to manual for specific transmission fluid type (e.g., THF or specialized gear oil).
Hydraulic System Wear:
As with many tractors of this age, potential wear in hydraulic pumps, cylinders, and valves can occur, requiring seal kits or component replacement.
Electrical Connector Corrosion:
Corrosion of electrical connectors due to exposure to elements is a common issue requiring inspection and cleaning.
Engine Overheating:
Can be caused by radiator blockage, faulty thermostat, or cooling fan issues.
Manufacturer History:
Allis-Chalmers was a prominent American manufacturer of agricultural and construction equipment, known for its orange tractors.
7000 Series:
The 7045 is part of the Allis-Chalmers 7000 series, which represented their premium tractor line introduced in the late 1970s.
Production Period:
The 7000 series was produced from approximately 1976 to 1985.
