Engine Model:
Likely a diesel engine from a reputable manufacturer (e.g., Case-Cummins, Perkins, or similar).
Displacement:
Typically in the 2.5L - 3.5L range for this class of equipment, exact details vary by specific sub-model and year.
Horsepower:
Estimated 45-60 HP, depending on the specific engine variant and configuration.
Torque:
Torque figures would be optimized for low-RPM pulling power, typical of diesel engines in this application.
Injection Type:
Likely direct injection or indirect injection, possibly with mechanical or early electronic fuel pumps depending on year.
Type:
Hydrostatic transmission (HST) is common for skid steers and many crawler loaders, offering variable speed and directional control.
Type:
Some models might feature a power shuttle or conventional manual transmission with torque converter for certain configurations (e.g., larger dozers).
Drive System:
Four-wheel drive or track drive, with differentials and final drives for power transfer.
Length:
Variable, but generally around 10-12 feet with standard bucket/blade.
Width:
Variable based on track width or tire size, typically 5-6 feet.
Height:
Around 7-8 feet to the top of the ROPS.
Operating Weight:
Likely in the 5,000 - 8,000 lb range, depending on configuration and options.
Engine Oil Change:
Typically every 250-500 operating hours, depending on application severity and oil type.
Hydraulic Fluid Change:
Often recommended at 1000-2000 operating hours or as indicated by fluid analysis.
Air Filter Replacement:
Inspect and replace as needed, typically based on hour meter or vacuum indicator.
Track Tension Adjustment:
Regular inspection and adjustment are critical for track life and performance.
Engine Oil:
API CD or CE classification, SAE 10W-30 or 15W-40 diesel engine oil (verify with manual for exact specification).
Hydraulic Fluid:
ISO VG 32 or 46 hydraulic fluid, or universal tractor transmission fluid (UTTF) depending on specific system design (verify with manual).
Coolant:
Ethylene glycol based antifreeze, typically a 50/50 mix with water.
Hydraulic Leaks:
Common in older, high-hour machines due to wear in pumps, cylinders, and hoses.
Undercarriage Wear:
Tracks, rollers, and sprockets are wear items and require regular inspection and replacement.
Starter And Alternator Issues:
Standard wear and tear on electrical components, especially in dusty and vibrating environments.
Transmission Control Issues:
Potential for wear in hydraulic control valves or charge pumps affecting drive performance.
Manufacturer:
CASE Construction Equipment, a long-standing manufacturer of heavy machinery.
Lineage:
The '450' designation has been used by CASE for various models over the years, typically indicating a compact to mid-size tractor or crawler loader.
Typical Production Era:
Likely produced from the 1970s through the 1990s, with potential updates and variations within this period. Specific model year is crucial for exact specs.
