Engine Family:
Likely Zetor's own direct-injection diesel engines, common in this era and series.
Engine Configurations:
Typically 3-cylinder and 4-cylinder naturally aspirated diesel engines.
Horsepower Range:
Estimated range from 35 HP (3320) to 60 HP (6340), specific figures vary by model within the series.
Torque Specifications:
Specific torque figures vary by engine variant; manual will provide precise values.
Injection System:
Direct injection, likely with rotary or inline fuel injection pumps (e.g., Zetor's own or Simms/Bosch).
Engine Oil Change:
Typically every 250 hours of operation, or annually.
Fuel Filter Replacement:
Recommended every 500 hours or as needed based on fuel quality.
Air Filter Cleaning Or Replacement:
Check and clean every 100-150 hours, replace as necessary.
Hydraulic Oil Filter Replacement:
Typically every 1000 hours or annually.
Engine Oil Type:
API CD/CE/CF or ACEA E2 specification diesel engine oil, viscosity SAE 15W-40 is common. Specific Zetor recommendations should be followed.
Transmission Hydraulic Oil Type:
Zetor recommends specific hydraulic oil or equivalent meeting UTF (Universal Tractor Transmission Oil) specifications, or ISO VG 46 hydraulic oil for some applications.
Coolant Type:
Ethylene glycol based antifreeze, mixed with distilled water (typically 50/50 ratio).
Common Wear Items:
Clutch wear, PTO seal leaks, hydraulic pump wear, and potential for radiator leaks are common on older tractors.
Electrical Gremlins:
Corrosion on electrical connections, especially in damp environments, can lead to intermittent issues.
