Air Conditioning System (Cabin)

Cleaning of Condenser and Wiremesh

For efficient cooling, the exterior of the condenser must be kept clean. This can be removed for cleaning as follows :

1.Open the hood; remove both side panels.

2.Loosen right wing bolt (A) of condenser and pull the bracket (B) towards RH side.

3.Further loosen the wing nut (F) and take out the bracket (G). Pull wiremesh (C) from RH side and take it out from upward direction.

4.Loosen wing nut (E) and slide out the condenser with receiver-drier assembly (D) towards RH side.

5.Condenser fins must be checked for blockage. This can be cleaned by blowing with compressed air or a highpressure washer not exceeding 7 bar (100 lbf/in2). Clean from the rear of the condenser. Fins blocked with oily substances may be cleaned with a detergent solution, preferably applied with a high pressure washer. Use soft brush or water carefully so as not to bend the fins.

6.When re-installing condenser, make sure that it engages properly in the lower and upper guide rails.

7.Also make sure that the condenser is securely centered in relation to the radiator or up to the bracket (H).

Clean the Cab Air Filters (Cabin)

For servicing the cabin air filters, remove 6 screws (A) of the filter grill and remove the front grill (B) along filters. Clean it with compressed air directed from upper side of the filters.

Cabin air filters should be cleaned after every 250 hrs. or even earlier if required.

During every service the cabin air filters should be cleaned. Even after this if the filter is found choked or damaged, replace it with a new one. Do not use dirty or damaged filter as the impure air may severely reduce the cooling effect.

Adding Hydraulic and Transmission Oil

Oil for hydraulic system & transmission is common in this tractor and reservoir for this common oil is the transmission case. Change Hydraulics and Transmission oil initially at 50 hrs. and subsequently at every 350 hrs. of operation. While changing, oil has to be filled in rear housing. Check the level of oil in the transmission & hydraulic reservoir as follows:

1.Keep the tractor on level ground.

2.Clean the area around dipstick cum filler cap (A) before removing.

3.Unscrew and remove the dipstick cum filler cap (A).

4.Clean the dipstick cum filler cap (A) and refit it in the housing.

5.Again unscrew the Dipstick cum filler cap and observe the level of oil on Dipstick of filler-level plug (A).

6.The oil level should be maintained between upper and lower mark on the Dipstick cum filler cap.

7.Add oil of specified grade only whenever required.

Front Axle Oil Level Checking

To check the oil level, keep the tractor on level ground. Clean the area around dipstick (B), remove the dipstick, clean it and refit it in the housing till it reaches its bottom. Again remove the dipstick and check oil level. The oil level should be maintained between upper and lower mark on it.

Draining Front Axle Oil

Drain oil from differential housing (C) as well as left hand side and right hand side hub housing (D) through respective drain plug.

Remove the respective drain plug and allow the oil to drain out. Be patient and allow the oil to drain for sufficient time. Refit the plug.

Filling Front Axle Oil

Reassemble the drain plug and fill the oil gradually from the oil filler neck till the oil reaches desired level on the dipstick. Be patient and wait till the oil settles down in housing before checking oil level on the dipstick.

Top-up Oil to Front Axle

To top-up oil in the front axle, open the dipstick (B) on both sides of swivel housing and refill oil via filling port (E) upto the required level and refit the dipstick. Ensure tightening the dipstick properly.

Hydraulic and Transmission Suction Oil Filter

Change Hydraulics and Transmission oil filter (A) initially at 50 hrs. and subsequently at every 350 hrs. of operation. These Spin-on type filters are located behind on RH side of the tractor. Remove old spin-on filters. Prime the new spin-on filter with clean oil, and fit them.

Hydraulic and Transmission Strainer

Clean suction strainer during every oil change. The suction strainer (B) is located on RH side of rear housing and can be removed as follows:

1)Remove suction filter of Hydraulic & Transmission.

2)Remove the cover plate by unscrewing four bolts.

3)Pull the suction strainer out from housing.

4)Clean the strainer in clean diesel fuel, using a soft brush, then blow dry with compressed air.

5)Refit the strainer.

6)Refit the cover plate and suction filter. For Service/Replacement of strainer contact your Mahindra Dealer.

NOTE : The Hydraulic and Transmission filter though resembles with engine oil filter, it differs in construction and usage. Hence these are not interchangeable.

Transmission Oil Drain

Drain plug (C) is provided on the transmission for draining transmission oil. The drain plug located at the bottom of the transmission case.
