Changing Oils and Filters On the TC48 / TC55
TC48DA – for PIN #'s HV11282 and above
TC55DA – for PIN #'s HX11752 and above
Before performing any of the following operations, be sure that engine is stopped and has been given adequate time to cool down

 

Changing the Engine Oil and Filter

  1. While engine is still somewhat warm take out drain plugs and drain oil

  2. Put plugs back in

  3. Remove old oil filter (be careful as oil will drain from filter)

  4. Apply a small amount of engine oil to the rubber seal of the new filter

  5. Tighten filter until it touches the mounting surface

  6. Tighten filter an additional ¾ turn by hand

  7. When a new filter is installed, engine oil typically decreases a little. Ensure that oil does not leak through the seal of the filter, then refill oil as needed.

Change oil and filter after first 50 hours and every 100 subsequent hours under normal conditions. If operating under sever conditions change every 70 hours after the first change.

 

Draining the Fuel Filter

  1. Ensure that there is fuel in the tank

  2. Close fuel shutoff valve (so that the handle is pointing towards the “C”)

  3. Take fuel sediment bowl off

  4. Open fuel shutoff valve and allow it to flow until only fuel is flowing from the filter base, no water

  5. Close shutoff valve

  6. Reattach fuel sediment bowl

  7. Open fuel shutoff valve

  8. Bleed fuel system

Drain fuel filter after every 100 hours of use

Changing the Fuel Filter

  1. Close fuel shutoff valve (so that the handle is pointing towards the “C”)

  2. Take fuel sediment bowl off by rotating the retaining nut

  3. Open fuel shutoff valve and allow it to flow until only fuel is flowing from the filter base, no water

  4. Install new fuel element

  5. Check the two O rings for any damage and replace them as needed

  6. Install the spring between the bottom of the fuel filter and the sediment bowl

  7. Reattach the sediment bowl

  8. Open fuel shutoff valve (so that the handle is pointing towards the “O”)

  9. Bleed fuel system

Replace fuel filter after the first 50 hours of use, and then after every 200 subsequent hours

 

Bleeding the Fuel System

Fuel system needs to be bled for the following reasons:

  • System has been drained

  • Filter has been replaced

  • Tractor has run out of fuel

  • Fuel lines have been disconnected

  • Injection pump has been replaced

To bleed fuel system:

  1. Ensure that there is fuel in the tank

  2. Open shutoff valve (so that the handle is pointing towards the “O”)

  3. Open the bleed screw on the fuel pump

  4. Close bleed screw when air-free fuel begins to flow

  5. Put throttle in the highest speed position

  6. Turn engine over for a few seconds

 

 

Bleeding the Injector Lines

Injector lines need to be bled for the following reasons:

  • Tractor has run out of fuel

  • Injectors have been replaced

  • Injection pump has been removed

To bleed injector lines:

  1. Loosen injector line fittings at the injectors

  2. Push hand throttle to highest speed position

  3. Crank engine until air-free fuel flows from each connection (do not crank engine continuously for more than 30 seconds)

  4. Tighten fittings to 18-22 ft-lbs (24-29Nm) of torque

If air remains in the system, repeat the above steps

  

Changing the Transmission, Rear Axle, and Hydraulic System Oil

  1. Oil drains best when engine is at operating temperature, but not hot

  2. Remove the filler plug and drain plugs to drain oil

  3. Reinstall drain plugs

  4. Fill with Ambra Multi G134 hydraulic oil to correct level on dipstick

  5. Replace dipstick and filler plug

Oil capacity – 11.1 gallons (42 liters)

Change transmission, rear axle, and hydraulic system oil after every 300 hours of use

 

 

Changing the Power Steering Oil

  1. Oil drains best when engine is at operating temperature, but not hot

  2. Take out drain plug to drain oil

  3. Put drain plug back in

  4. Turn the filter / reservoir assembly counterclockwise to detach it

  5. Apply a small amount of oil to the rubber seal of the new filter

  6. Tighten filter until it touches the mounting surface

  7. Tighten filter an additional ¾ turn by hand

  8. Remove filler plug / dipstick and fill the reservoir with Ambra Multi G 134 hydraulic oil

  9. Put filler plug / dipstick back in

Power steering oil needs to be changed after every 600 hours of use

 

 

Hydraulic Filter

  1. Remove old filter

  2. Apply a small amount of oil to the rubber seal of the new filter

  3. Tighten filter until it touches the mounting surface

  4. Tighten filter an additional ¾ turn by hand

  5. Run engine and check filter for leaks

  6. Stop engine

  7. Check hydraulic oil level and refill as needed

Replace hydraulic filter after first 50 hours and then after every 300 subsequent hours

 

 


Changing the Front Axle Differential Case and Final Reduction Gear Case Oil (Front-Wheel Drive)

  1. Take out drain plug and drain oil while it is still warm

  2. Put drain plug back in

  3. Take out dipstick / filler plug

  4. Fill axle with Ambra Multi G 134 hydraulic oil

  5. Put dipstick / filler plug back in

Oil Capacity – approximately 1.5 quarts (1.4 liters)

Front axle differential case and final reduction gear case oil should be changed after every 300 hours of use
