Real Mechanical Wear v1.0.0.0 FS25
Real Mechanical Wear
Real Mechanical Wearadds a detailed mechanical wear and maintenance system to Farming Simulator 25.
Instead of vehicles simply losing a generic amount of condition, this mod simulates the wear of individual mechanical systems based on engine load, operating conditions, contamination, temperature and usage.
The harder you work your machines, the more mechanical stress they experience.
Features
Engine Wear
The engine is divided into several internal components:
Cylinder wear
Piston wear
Bearing wear
Crankshaft wear
Valve wear
Compression loss
Blow-by
Internal friction
Carbon buildup
Power loss
Increased fuel consumption
Starting reliability
Idle stability
Engine wear is affected by the actual operating stress of the vehicle.
Constantly running an engine under heavy load will cause significantly more wear than normal light-duty operation.
Oil System
The oil system is simulated independently and includes:
Oil level
Oil quality
Oil contamination
Oil filter condition
Poor oil condition increases internal friction and accelerates mechanical wear.
Cooling System
The cooling system includes:
Coolant level
Coolant quality
Radiator dirt
Cooling fan condition
Thermostat condition
Water pump condition
Poor cooling can increase thermal stress and accelerate mechanical damage.
Turbocharger
Turbocharged vehicles can experience:
Turbo bearing wear
Turbo shaft wear
Turbo wear is integrated into the overall mechanical condition of the vehicle.
Transmission & Drivetrain
The drivetrain includes independent wear for:
Clutch
Transmission gears
Differential
Transmission oil
Heavy work and prolonged high-load operation can accelerate drivetrain wear.
Fuel System
The fuel system includes:
Injector condition
Fuel pump condition
Fuel filter condition
As components deteriorate, vehicle performance and reliability can be affected.
Battery & Starting System
The electrical starting system includes:
Battery capacity
Battery charge
Starter condition
Alternator condition
A severely damaged battery or starter can prevent the engine from starting.
A jump-start function is also available when necessary.
Exhaust Smoke & Performance
Mechanical problems can have visible consequences.
Depending on the condition of the engine, the vehicle may experience:
Increased exhaust smoke
Reduced engine power
Increased fuel consumption
Poor idle stability
Reduced starting reliability
Realistic Failure System
Severe mechanical deterioration can eventually lead to failures.
Ignoring maintenance is therefore no longer just a cosmetic issue — it can become an actual operational problem.
Maintenance System
The mod provides a comprehensive maintenance system with separate service options:
Engine oil change
Oil filter replacement
Air filter service
Coolant service
Radiator cleaning
Water pump replacement
Cooling fan replacement
Thermostat replacement
Turbocharger service
Clutch replacement
Transmission repair
Transmission oil change
Battery replacement
Starter replacement
Alternator replacement
Fuel system service
Complete engine overhaul
Maintenance costs are calculated according to the vehicle price and the severity of the wear.
Dynamic Wear Simulation
Wear is not simply based on operating hours.
The system uses a mechanical stress model where sustained high-load operation causes disproportionately higher wear.
For example:
Light work → Low mechanical stress → Slow wear
Normal work → Moderate stress → Normal wear
Heavy work → High stress → Rapid wear
Additional factors such as oil contamination and overheating can further increase the wear rate.
This means that two identical tractors with the same operating hours can have completely different mechanical conditions depending on how they were used.
Carbon Buildup
Carbon buildup is simulated separately.
Extended low-load and idle operation can increase carbon accumulation, while sustained higher-load operation can gradually reduce buildup.
This creates another reason to operate and maintain machines properly.
Persistent Vehicle Condition
Mechanical condition is saved with the vehicle.
Your machines retain their:
Engine wear
Oil condition
Cooling condition
Turbo wear
Transmission wear
Battery condition
Fuel-system condition
Active failures
Other mechanical data
The machine therefore develops its own mechanical history throughout your savegame.
In-Game HUD
The mod provides a dedicated mechanical HUD displaying important information about the vehicle’s condition.
The HUD can be switched between different display modes or hidden completely.
Difficulty
Wear difficulty can be adjusted in-game.
Increase the difficulty for a more demanding mechanical simulation, or reduce it if you prefer a more relaxed gameplay experience.
Compatibility
Real Mechanical Wear is designed to automatically attach to motorized vehicles.
This means it can work with tractors, harvesters, trucks and other motorized vehicles without requiring modifications to the original vehicle files.
Important
This mod is designed for players who want a deeper and more realistic vehicle maintenance experience.
If you prefer a simple arcade-style gameplay experience with minimal maintenance, this mod may make vehicle operation considerably more demanding.
Recommended for players who enjoy realistic farming, machinery management and long-term vehicle ownership.
Keyboard Controls
The default keyboard controls are:
| Key | Function |
| ————– | ———————————– |
| F2| Toggle Mechanical HUD |
| F3| Open Maintenance Panel |
| F5| Increase Wear Difficulty |
| F4| Decrease Wear Difficulty |
| F6| Jump Start |
| END| Select next maintenance item |
| DELETE| Confirm selected maintenance action |
F2 – Mechanical HUD
Press F2to cycle through the available HUD display modes:
Compact → Full → Hidden
This allows you to keep the mechanical information visible without taking too much screen space.
F3 – Maintenance
Press F3to open the maintenance panel.
Use:
END– Select the next maintenance operation
DELETE– Perform the selected maintenance operation
Maintenance costs depend on the vehicle price and the severity of the component wear.
F4 / F5 – Difficulty
F5increases the mechanical wear difficulty.
F4decreases the mechanical wear difficulty.
Higher difficulty results in faster mechanical deterioration.
F6 – Jump Start
Press F6when the vehicle has a battery or starter problem and requires a jump start.
A jump start does not repair the underlying mechanical problem. Proper maintenance or component replacement may still be required.
Changing the Controls
The default controls can be changed through the Farming Simulator 25 control settings.
Open:
Options → Controls → Keyboard
Search for the Real Mechanical Wearactions and assign your preferred keys.
Recommended default layout:
F2– HUD
F3– Maintenance
F4/ F5– Difficulty
F6– Jump Start
The maintenance navigation uses the END key and DELETE by default.
