Make Model:
Likely a Mitsubishi industrial diesel engine (e.g., S4S, S4Q2 series, or similar, specific model dependent on exact FD50 variant and year).
Engine Type:
Diesel (most common for this class of forklift)
Displacement:
Typically 2.0L to 3.5L for this capacity forklift, exact displacement varies by engine option. For example, S4S-DT is 2.5L.
Horsepower Range:
Estimated 45-65 HP, depending on specific engine variant and emissions standards.
Torque:
Specific torque figures will be detailed in the manual; typically in the range of 120-170 lb-ft.
Injection Type:
Direct injection, likely with mechanical or electronic rotary injection pump depending on the year/model.
Coolant Type:
Ethylene Glycol based coolant with corrosion inhibitors (specific type and mixture ratio detailed in manual).
Type:
Automatic transmission (Torque Converter with Powershift planetary gearsets) is standard for this model series.
Type:
Manual transmission may have been an option on some very early or specific configurations, but automatic is predominant.
Shift Control:
Typically lever-actuated (e.g., forward, neutral, reverse, 1st, 2nd gear selection).
Transmission Fluid:
Dexron III/Mercon compatible ATF (Automatic Transmission Fluid) or equivalent industrial lubricant; specific Mitsubishi specification will be in the manual.
Overall Length:
Varies significantly based on mast type and configuration; typical for a 5000 lb capacity forklift. Manual will provide specific dimensions.
Overall Width:
Standard configuration usually around 48-52 inches. Manual will detail.
Mast Height Lowered:
Varies by mast type (e.g., 2-stage, 3-stage); typical range 80-90 inches. Manual will specify.
Mast Height Raised:
Varies significantly by mast type and lift height; can range from 160-200+ inches. Manual will detail.
Operating Weight:
Approximately 8,000 - 10,000 lbs, depending on configuration and attachments. Manual will provide precise weight.
Rated Capacity:
5,000 lbs (2,300 kg) at a standard 24-inch load center.
Industry Standards:
Designed and manufactured to meet relevant industry safety standards (e.g., ANSI/ITSDF B56.1 for North America, FEM standards in Europe).
Operator Presence System:
Standard feature that prevents hydraulic functions and travel if the operator is not seated.
Parking Brake:
Typically a mechanical or hydraulic type, designed to hold the forklift securely when parked.
Overhead Guard:
Standard protective structure to guard the operator from falling loads.
Seatbelt:
Standard safety restraint for the operator.
Load Backrest:
Extension to prevent a load from shifting backward towards the operator.
Initial Service:
Typically at 50 hours or 1 month for initial break-in service (e.g., oil and filter change).
Routine Oil Change:
Every 250-500 operating hours or 6-12 months, depending on operating conditions. Manual will provide precise intervals for engine and hydraulic oil.
Air Filter Replacement:
As needed based on operating environment, but typically inspected daily and replaced every 500-1000 hours.
Engine Oil:
CD or CE grade diesel engine oil (e.g., SAE 15W-40) or specific Mitsubishi-approved lubricant. Capacity around 7-9 quarts. Manual to confirm.
Hydraulic Fluid:
ISO VG 32 or 46 hydraulic fluid, or a high-quality universal tractor transmission oil (UTTO) if specified. Capacity around 10-15 gallons. Manual to confirm.
Coolant Capacity:
Approximately 10-12 quarts. Manual to confirm.
Common Wear Items:
Brake pads/linings, hydraulic filters, engine air/fuel filters, seals in mast cylinders, tire wear.
Potential Failures:
Hydraulic pump wear leading to slow lift/tilt, transmission torque converter issues, engine overheating due to radiator clogging, starter/alternator failure, common in high-usage environments.
Manufacturer:
Mitsubishi Heavy Industries, Ltd. (forklift division, often marketed under the Mitsubishi brand or as part of a larger conglomerate).
Fd Series:
The FD series represents Mitsubishi's line of internal combustion engine (ICE) forklifts, known for their robustness and reliability. The FD50 is a mid-range pneumatic tire forklift.
Production Years:
The FD50 model has been in production across various generations; specific year ranges for this manual would depend on the exact revision, but generally covers models from the late 1980s through the 2000s, with updates for evolving engine and emission standards.
