Maintenance
Warning! Before performing any maintenance or repairs, disengage the PTO, move the speed control pedals to the neutral position, engage the parking brake, stop the engine and remove the key to prevent unintended starting.
Engine
Refer to the Yanmar Owner’s Manual for all engine maintenance intervals, procedures, specifications and instructions.
NOTE: Maintenance, repair, or replacement of the emission control devices and systems which are being done at owner’s expense may be performed by any engine repair establishment or individual. Warranty repairs must be performed by a Cub Cadet Dealer.
Changing the Engine Oil
Warning! If the engine has been recently run, the engine, muffler and surrounding metal surfaces will be hot and can cause burns to the skin. Exercise caution to avoid burns.
Maintain oil level as instructed in engine manual. Change the oil and filter after the first five hours. The oil filter should be changed at every oil change interval. Be careful not to spill oil on any of the belts.
To complete an oil change, proceed as follows:
1.Run the engine for a short time to warm the engine oil. The oil will flow more freely and carry away more impurities. Use care to avoid burns from hot oil.
2.Locate the oil drain plug on the left lower side of the oil pan. See Fig.
Washer
Oil Drain Plug 
Figure
3.Place an appropriate oil collection container below the oil drain plug, to collect the used oil. Remove the plug and washer to start draining the oil. Remove the oil fill cap/ dipstick from the oil fill tube.
4.After draining the oil, wipe any residual oil from the oil
drain hose. Thread the oil drain plug and washer into the oil pan fully tighten the plug.
5.Refill the engine with new oil. Refer to the Yanmar Owner’s
Manual for information regarding the volume and weight of engine oil.
Fuel Specifications
Use good quality fuel to get the correct power and perform the engine. The recommended fuel specification for diesel engines is shown below.
Cetane number — 45 minimum
Viscosity — 2.0/4.5 centistrokes at 40 C (104 F)
Density — 0,835/0,855 kg/litre
Sulphur — 0.2% of mass, maximum
Distillation — 85% at 350 C (662 F)
Cetane number: Cetane number indicates ignition per Fuel with a low cetane number can cause cold start problems and affect combustion.
Viscosity: Viscosity is the resistance to flow and if this is outside limits, engine performance can be affected.
Density: Low density will reduce engine power, higher density will increase engine power and exhaust smoke.
Sulphur: High sulphur content (not normally found in Europe, North America or Australasia) can cause engine wear. If only high sulphur fuels are available, it will be necessary to use a highly alkaline lubricating oil in the engine or reduce the lubricating oil change interval.
Distillation: This is an indication of the mixture of differ hydrocarbons in the fuel. A high ratio of light weight hydrocarbons can affect the combustion characteristics.
Low temperature fuels: Special winter fuels may be available for engine operation at temperatures below 0 C (32 F). These fuels limit the formation of wax in the fuel oil at low temperatures.
If wax forms in the fuel oil, this could stop the flow of fuel oil through the filter.
Aviation kerosene and R.M.E. type fuels: These fuels may be used, but can effect the engine performance and starting ability. The only aviation fuels that are permitted for use with these engines are: JP5, Jet A and JP8 providing that 5% spindle oil is added, Aviation fuel JP4 is not recommended. For more information on aviation fuels refer to the Service department. Only up to 5% R.M.E. in mineral oil diesel fuel is permitted. Biodiesel blends of up to 20% B100 and #2 diesel fuel (B20) are allowed.
