Your engine does not stay fresh forever. Oil gets dirty, parts wear out and a turbo can fail if you keep skipping maintenance. Hyper Realistic Maintenance 2 puts a deep, ongoing mechanical simulation into every motorized vehicle in your saved game. That includes tractors, trucks, harvesters and cars. The changes matter while you play, not just on a cosmetic number screen.
The DEF Pack mod is recommended if you want to simulate the new DEF systems. The DEF Mod Pack and Variable Tire Pressure mods work together without compatibility issues. More translations are in development.
Features
- Engine: you get 5 independent parts, cylinder, piston, bearings, crankshaft and valves, and they influence each other. Cylinder wear creates more blow-by, dirtying the oil and pushing wear even further.
- Thermal: put the engine under load and coolant temperature rises. If the radiator is degraded, the engine overheats.
- Fluids: you can check the oil level, oil contamination and coolant level, and each one needs maintenance.
- Transmission: clutch, gearbox, turbo and battery/starter motor all wear over time.
- Failures: above approximately 35% wear on the relevant component, failures become much more likely. Critical overheating above 118 °C is guaranteed, so luck does not decide it.
- Behaviour by vehicle type: tractors, trucks, harvesters and cars wear at different realistic rates.
- Real power loss cuts the engine’s effectively available torque. You can feel that loss when you are working in the field.
- Real no-start conditions: a flat battery or worn starter motor can truly keep the engine from turning over, and a warning appears on screen.
- Harvesters lose real threshing efficiency when their engine condition gets worse.
- Scheduled maintenance gives you 10 maintenance items to look after, engine oil, filters, hydraulic/transmission oil, coolant, grease, belts and much more. Each has its own interval and a real cost for the farm, adjusted automatically to the vehicle’s actual power. Leave the service too long and wear accelerates by up to +120%.
- Vehicle HUD with 3 pages, an overview, detailed engine diagnostics and maintenance status. You can change its position in the game Settings menu.
- The game’s repair screens, shop, farm workshop and mobile workshop can now handle a complete HRM2 service too.
- Works completely standalone.
- Have the 4×4 Traction System mod installed as well? The two mods detect one another automatically, and using 4WD or the differential lock gives the transmission a real additional driving effect.
- Multiplayer is significantly improved and was tested on a real dedicated server. Check the changelog for details and known limitations.
- Maintenance progress is saved in the saved game.
Changelog
V3.1.5.0
Fixed: a flat battery could not be recovered. Since the engine would not start, the alternator never charged it.
New: on foot, stand next to the machine and use “Charge the battery” in the Daily care tab to charge it to 90%.
A new battery from the workshop now comes fully charged.
Finish any workshop job and the machine comes back with at least 90% charge.
The weak battery message shown when starting now tells you where to charge it.
V3.1.4.0
Fixed: the maintenance window, Left Alt + M, would not open inside a vehicle. You can now open it on foot or in the vehicle.
New: the instrument cluster can be moved. Open the window, choose Settings > “Cluster position” > “Move with the mouse”, and drag it wherever you want. Right click or Esc finishes the move. Choose “Reset” to return it to the original place.
Fixed (multiplayer): every player now keeps their own cluster position, cluster size, cluster on/off and work sounds. Previously, the server and the savegame overwrote those settings for everyone.
V3.1.4.0
HRM2 ULTRA, complete rewrite: every part simulated like the real machine.
- Every machine is made from its real parts, engine internals, injection, turbo, after-treatment EGR / DOC / DPF / SCR, cooling, electrics, transmission, hydraulics, PTO, brakes, steering, tracks and EV parts. Each part has its real service life, wears from what the machine actually does and fails in its own ways, through 4 stages.
- Engine oil comes with real chemistry, including viscosity, soot, fuel dilution, glycol, TBN and wear metals, as well as lab oil analysis.
- The thermal model has thermostat, radiator fouling, boiling and ECU protection. Warm-up is quicker in game, about 1 °C every 4 s at idle. Park the engine and it cools on the game clock, with about 1 hour needed to lose half the heat.
- Battery / alternator, glow plugs and cold starts, hot shutdown damage on turbos, DPF regeneration, passive, active and parked, and DEF inducement.
- Machines with an ECU use J1939 fault codes. Older machines are diagnosed through smoke, noises and gauges.
- Workshop: service packs at 500 / 1000 / 2000 / 3000 h, inspections, repairs, overhauls, parts quality with delivery times, dealer, mobile mechanic or do it yourself, plus opening hours.
- Press the game’s workshop “Repair” button to start a dealer job, then the HRM2 window opens on the Workshop tab. It shows the parts arrival, the workshop work and when the machine will be ready, today / tomorrow at hh:mm.
- Workshop jobs and parts delivery run with the game clock. In the HRM2 window, use “Time speed – / +” to speed up time and finish sooner. Parked machines keep progressing too.
- Daily care on foot lets you do a walk-around, grease the machine, drain the water separator, blow out the radiator and air filter, and top up fluids. The bar fills right away after the care.
- Workshop sounds include the ratchet when you do the work, the dealer’s impact wrench, pouring oil, the grease gun and compressed air for blowing filters. You can switch these sounds off.
- Fluids included: DEF tanks, 5 000 / 10 000 / 15 000 L, plus pallets of 5 L engine oil 15W-40 and hydraulic oil UTTO cans, 56 x 5 L. A pallet near the machine gets used first when you top up or change the oil yourself. Empty cans disappear.
- Implements and trailers are included too: shares, tines, discs, knives, knotters, chains, PTO shafts, gearboxes, bearings and brakes. Worn tools raise the draught.
- Real machine hours are read on load. Once a tractor reaches 3000 h, it is no longer like new. You can see the hour meter on the instrument cluster and in Zasty HUD.
- Reads the 4×4 Traction System: drive with 4×4 or diff locks engaged and the differentials, final drives and front drive shaft wear.
- Realistic exhaust smoke, failure noises with the machine’s own sounds, brand reliability, used machines with hidden faults and farm parts store.
- New windows keep the camera locked while open, and there is an own instrument cluster with 16 warning lamps.
- Singleplayer, multiplayer and dedicated servers.
KEYS (default)
Left Alt + M: Maintenance window, in the cab, or on foot next to a machine.
Left Alt + N: Show / hide the instrument cluster.
These are the default keys. If one of them is already used by the game or by another mod, go to Options > Controls and set the key you prefer, to avoid conflicts.
