Hydraulics and Transmission Oil Transmission Oil Oil Level Check Level Level

The Transmission, Hydraulics and Steering use oil from a common reservoir. To check the oil level proceed as follows : dipstick.

1. Keep the tractor on level ground and clean the area around dipstick.

2. Remove the dipstick (A), clean it and refit it in the housing till it reaches its bottom.

3. Again remove the dipstick and check oil level. The oil level should be maintained between upper and lower mark on it. Refill oil via the filler neck up to the required level if necessary. The oil should be replaced initially at 50 hours and subsequently after every 400 hours of operation. The Oil filter element shall be also replaced whenever oil is changed.

Adding Oil Oil

While changing the complete oil of transmission, 6.60US gallon (25 litre) oil has to be filled in transmission housing. To add oil, proceed as follows :

1. Keep the tractor on level ground and clean the area around dipstick.

2. Remove the dipstick to expose the port.

3. Add oil of specified grade through the port

4. Allow the oil to settle down and check oil level as detailed above.

Oil Drain Drain Oil Drain Drain

To drain oil, proceed as follows :

1. Keep the tractor on level ground.

2. Remove the drain plug (B) and allow oil to drain out.

3. Refit drain plug (B after the oil is completely drained out.

Note : Note : Note : Note : Draining oil consumes time. Allow sufficient time for draining the oil.

Hydraulics and Transmission Oil Filter Hydraulics Transmission Filter Hydraulics and Transmission Oil Filter Hydraulics Transmission Filter

The Transmission, Hydraulics and Steering use oil from a common reservoir and share a common oil filter element. The oil filter element should be replaced initially at 50 hours and subsequently after every 200 hours of operation.

This filter shall be also replaced whenever oil is changed. The oil filter mounted on transmission housing can be accessed after removing the LH - Connecting plate (A).

To replace the oil filter element, proceed as follows : To replace the oil proceed as follows

Front - Front Wheel “Toe-in” Check

In the event of the tie rod setting being interfered with, then it is necessary to adjust the TOE-IN. Before measuring and adjusting the TOE-IN, ensure the front wheels are in the straight ahead position and the front axle is not tilted.

After adjusting the front wheel tread and with all connections secured, the front wheel Toe-in ( A – B ) shall be Zero.

Measure the distance between the outer edges of the wheel rims at the same height as the hub. Mark the point measured and turn the wheels half revolution so that the marked points are at the rear. This distance must be the same as measured before earlier.

Loosen the nut (C) on both sides of tie rod and turn the tie-rod (D) clockwise or anticlockwise to adjust the TOE-IN as required.

Oil has a limited working life after which the effects of time, condensation, engine heat and by-products of combustion will combine to reduce its lubricating properties. It is therefore, detrimental to use a lubricant for more than the specified period. The intervals between lubricant changes detailed in this manual have been determined after prolonged tests and have been proved the most suitable for normal operation. In extremely arduous conditions, however, it may be necessary to reduce these periods and this point should be discussed with Mahindra tractor dealer.

Oil can go bad while in the engine due to condensation and leakage of Diesel. Also running of engine in cold conditions may lead to such contamination.

It is generally advised not to mix different brands or types of oil. Certain additives blended by the oil manufacturers to meet certain performance levels may adversely affect that of other brands causing compatibility problems.

NOTE : The term heavy duty as used here does not refer to the viscosity rating or “weight” of the oil.

Lubricant Storage

Lubricant Storage

Tractors can operate efficiently only when clean oils are used Oils when stored shall be protected from dust, moisture and other contaminants. Store containers on their side to avoid water and dirt contamination. Please ensure that old and used oils are suitably disposed.

Alternate and Synthetic Lubricants

Alternate and Synthetic Alternate and Conditions in certain locations may warrant usage of other lubricants than specified in the manual. In such cases the alternates may be used provided they meet the minimum performance levels specified. Synthetic lubricants may be used if they meet minimum performance levels specified in the manual.

Manufacturers of these oils may be consulted for temperature applicability and suitability.

Bio-degradable oils and fuels are not advised.

Diesel Oil

Engine oil (for use in the crankcase) should be a well refined petroleum oil free from water and sediment. Heavy duty oils are additive type oils possessing the oxidation-stabilising, anticorrosive and anti-sludging properties necessary to make them generally suitable for high speed diesel engines. They provide the most satisfactory lubrication and should be used in diesel engines with present day diesel fuels. The quality of the base oil and the amount and type of additives used, determines their suitability for use in high speed diesel engines under severe operating conditions and also their suitability for use with diesel fuel containing sulphur or other injurious products.

Please note that engine breathes even while it is not running and once condensation take place rapid deterioration of oil may happen.Hence storage time for the engine should not be longer than one year but it is advisable to check the oil after 6 months. It is not the policy of the Mahindra & Mahindra Ltd. to guarantee oil performance under the conditions of operation, and its compatibility with the diesel fuels used, must remain with the supplier of the lubricant. High-speed diesel fuels and lubricants should be procured from a reliable source. When in

Refer table A for oil specifications. Other oils can be used if they meet minimum requirement of :

- CCMC D-4 / G-4 / PD-2

- MIL - L - 2104E.

Multi-Viscosity Diesel Engine oils are preferred.

Note Note Note : If diesel fuel with sulphur content greater than 0.5% is used, reduce the service interval by 50%.

Selecting the Viscosity of Engine Oil (EO) the Viscosity of Engine Oil Oil

During cold weather the selection of oil should be based on the coldest anticipated operating temperature to make starting easier.

During hot weather, selection should be based on the highest anticipated operating temperature.

When the prevailing temperature changes substantially, even though the regular intervals of lubricant change have not been reached, the lubricant must be changed.

Refer Oil Specifications Chart for oil specifications at different range of ambient temperatures.

Following oils of SAE grade 15W40 are recommended for temperature range of -15°C to 50°C.

1. Citgo - Citgard 500 15W40.

Oil Specifications Chart (Table A)

It is generally advised not to mixed different brands & types of oils.

Note Note Note Note Note : It is not necessary to change the lubricant when the temperature enters into a different range during a working day, unless difficulty in starting is experienced. Change oil if the tractor is not used for 6 months.

PRECAUTIONS :

After changing the oil, operate the engine at low speed without load, for at least 5 minutes. This will allow the oil to work into the bearings and onto the cylinder walls.
