Model Code:
BD-144 (typically)
Displacement:
144 cubic inches (approx. 2.36 liters)
Bore X Stroke:
3.5625 in x 3.75 in (90.5 mm x 95.3 mm) - Typical
Horsepower Rated:
Approximately 40-45 PTO HP (varies with configuration and engine tuning)
Torque:
Good low-end torque characteristic of diesel engines.
Injection System:
Direct Injection, typically Lucas or CAV distributor type injection pump.
Oil Type:
CD or CE rated diesel engine oil, viscosity dependent on ambient temperature (e.g., SAE 15W-30, SAE 10W-30).
Oil Capacity:
Approximately 5.5 US quarts (5.2 liters) with filter.
Type:
Constant Mesh Gearbox
Speeds:
Typically 8 Forward, 2 Reverse speeds (4 main gears with a high/low range selector).
Transmission Options:
Possible variations might include a torque amplifier or creeper gear options on some models, though not standard.
Gear Selection:
Manual shift via gear levers.
Transmission Fluid:
API GL-4 lubricant, SAE 80W-90 gear oil is common. The manual will specify exact IH or equivalent fluid.
Safety Features:
While modern safety ratings do not apply, standard safety features include brakes, steering, and a robust chassis.
Safety Considerations:
PTO safety shield, brake operation, clutch engagement, proper tire inflation, and stable operation on uneven terrain.
Operator Station:
Basic operator station with fenders and a seat. ROPS (Roll-Over Protective Structure) and seat belts were not standard but can be retrofitted on many models.
Engine Oil Change:
Typically every 100-125 operating hours or annually, whichever comes first.
Air Filter Cleaning:
Check and clean air filter pre-cleaner and element regularly, especially in dusty conditions.
Fuel Filter Replacement:
Recommended replacement at scheduled intervals or if experiencing fuel delivery issues.
Transmission Fluid Change:
Recommended every 1000-1200 hours or every 2 years.
Hydraulic Fluid:
IH Hy-Tran (or equivalent tractor hydraulic fluid) meeting IH B-6 specification.
Coolant Type:
Ethylene glycol based antifreeze mixed with distilled water (50/50 ratio recommended for freeze and corrosion protection).
Common Problems:
Hydraulic leaks, worn clutch components, front seal leaks, starter issues, carburetor wear (on petrol variants if applicable), and general wear and tear associated with older agricultural machinery.
Preventative Maintenance:
Regular lubrication, checking fluid levels, keeping air filter clean, and addressing minor issues before they become major problems are crucial for longevity.
Parent Company:
International Harvester (IH)
