Engine Manufacturer:
Perkins
Engine Variants:
Likely Perkins 3.152, 3.904, and potentially 4.236 diesel engines, depending on the specific model within the 500 series.
Engine Configuration:
Inline 3-cylinder or 4-cylinder
Horsepower Range:
Approximately 45-75 PTO horsepower, depending on the specific engine and model variant.
Torque Characteristics:
Designed for strong low-end torque delivery for pulling heavy loads and operating at lower RPMs.
Fuel Injection System:
Typically rotary or inline fuel injection pumps (e.g., CAV DPA, Simms, or Stanadyne), with mechanical governor control.
Engine Oil Type:
API CD or CE classification, SAE 15W-30 or 10W-30 depending on climate. (Refer to manual for exact spec).
Engine Oil Capacity:
Approximately 7-8 liters (7.4-8.5 US quarts), depending on engine variant. (Refer to manual for exact spec).
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors, typically a 50/50 mix with water. (Refer to manual for exact spec).
Primary Transmission Type:
The series offered multiple transmission options, including an 8-speed gearbox.
Optional Transmission 1:
Multi-Power transmission (offered on some models like MF590), providing a synchronized 'high-low' range selection without disengaging the main drive.
Optional Transmission 2:
Select-O-Speed transmission (less common for this series, more typical of earlier models, but may be present in variations or as an aftermarket option).
Clutch Type:
Dual-stage clutch (for PTO engagement and transmission drive) or a single-stage clutch depending on specific configuration.
Pto Speeds:
Typically 540 RPM PTO, with options for 1000 RPM or ground speed PTO on some variants.
Transmission Hydraulic Fluid Type:
Massey Ferguson Approved Hydraulic Fluid (e.g., M-1111, M-1127, or M-1135 depending on the specific transmission and hydraulic system design). Often a UTF (Universal Tractor Transmission) fluid or suitable mineral oil. (Refer to manual for exact spec).
Transmission Hydraulic Fluid Capacity:
Approximately 25-35 liters (6.6-9.2 US gallons), for the combined transmission, hydraulic, and rear axle lubrication system. (Refer to manual for exact spec).
Engine Oil Change Interval:
Typically every 250-500 operating hours, or annually. (Refer to manual for exact intervals).
Fuel Filter Replacement Interval:
Every 250 operating hours or as needed if fuel quality is suspect. (Refer to manual).

Frequent checks, cleaning every 100-250 hours, replacement as needed depending on operating conditions. (Refer to manual).
Hydraulic Filter Replacement Interval:
Typically every 500-1000 operating hours, or annually. (Refer to manual).
Transmission Hydraulic Fluid Spec:
Massey Ferguson Approved Hydraulic Fluid (M-11xx series) or equivalent UTF. Critically important to use the correct fluid to avoid damage to transmission and hydraulics.
Common Wear Items:
Clutch wear, hydraulic pump wear, PTO engagement issues, and potential for front axle kingpin wear are common over time. Electrical harness degradation can also occur.
Multi Power Transmission Concerns:
The Multi-Power system can be prone to issues with its internal clutch pack and hydraulic control valve if not properly maintained or if subjected to abuse.
Select O Speed Transmission Concerns:
If equipped, the Select-O-Speed can be sensitive to fluid quality and fill levels, and clutch pack wear can affect shifting.
Grease Points Schedule:
Regular lubrication of steering joints, PTO shaft, front axle pivot, and clutch linkage is crucial. Specific intervals detailed in the manual.
