Tighten filter an additional ¾ revolve by hand

When a new filter is installed, engine oil frequently decreases a little. Ensure the oil does no leak through the seal the the filter, then refill oil as needed.

You are watching: New holland tractor hydraulic fluid change

Change oil and filter after first 50 hours and also every 100 subsequent hrs under normal conditions.

Draining the Fuel Filter

Ensure that there is fuel in the tank

Close fuel shutoff valve (so the the handle is pointing in the direction of the “C”)

Take fuel sediment bowl off

Open fuel shutoff valve and permit it to circulation until only fuel is flowing from the filter base, no water

Close shutoff valve

Reattach fuel sediment bowl

Open fuel shutoff valve

Bleed fuel system

Drain fuel filter ~ every 100 hours of use

Changing the Fuel Filter

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

Take fuel sediment key off by rotating the retaining nut

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

Install new fuel element

Check the two O rings for any kind of damage and also replace them together needed

Install the spring between the bottom the the fuel filter and the sediment bowl

Reattach the sediment bowl

Open fuel shutoff valve (so the the take care of is pointing towards the “O”)

Bleed fuel system

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

Changing the waiting Cleaner Elements

Outer Element

Remove air cleaner covering by pushing under on it and rotating that counterclockwise

Pull outer aspect out that assembly

Clean loosened dirt from element

Check the finish of the canister for dirt

Blow compressed air (under 30psi) native the inside of the filter come clean it

Check within diameter seals for damages (if damaged, change element)

Put a light inside the aspect to examine for file leaks or because that the bonding the the record to the end plate (if leaks are found, change element)

Push major element ago into canister and also reinstall

Put air cleaner cover into place

Clean outer facet after every 100 hrs of service

Inner Element

Remove wait cleaner cover and also outer element to expose the inner element

Inspect the inner aspect by put a light inside the element. If small or no light shines v the element it is partially clogged.

Clean dirt from element and also canister

Check seals for damages (if damaged, change element)

Push element back into canister

Push outer facet over the peak of the within element and also clamp wait cleaner cover into place

Change inner aspect after every 1000 hours or every 3rd outer element change, whichever comes first

Hydraulic Filter

Remove old filter

Apply a tiny amount that oil come the rubber seal that the new filter

Tighten filter until it touches the mounting surface

Tighten filter second ¾ rotate by hand

Run engine and also check filter because that leaks

Stop engine

Check hydraulic oil level and refill together needed

Replace hydraulic filter after first 50 hours and also then ~ every 300 succeeding hours

Changing the Transmission, behind Axle, and Hydraulic mechanism Oil

Oil drains ideal when engine is at operating temperature, however not hot

Remove transmission and rear axle drainpipe plugs

Drain oil and reinstall plugs

Take the end filler plug and also fill through NH 134 hydraulic oil to correct level ~ above dipstcik

Put dipstick and also filler plug back in

Bleeding the Fuel System

Fuel system needs to be bled for the adhering to reasons:

System has actually been drained

Filter has been replaced

Tractor has run out of fuel

Fuel lines have been disconnected

Injection pump has actually been replaced

To bleed fuel system:

Ensure that there is fuel in the tank

Open shutoff valve (so that the manage is pointing towards the “O”)

Open the bleed screw top top the fuel pump

Close bleed screw once air-free fuel starts to flow

Put throttle in the greatest speed position

Turn engine over because that a couple of seconds

Bleeding the Injector Lines

Injector lines need to be bled for the following reasons:

Tractor has run the end of fuel

Injectors have actually been replaced

Injection pump has actually been removed

To bleed injector lines:

Loosen injector line fittings in ~ the injectors

Push hand throttle to highest possible speed position

Crank engine till air-free fuel operation from each link (do no crank engine repeatedly for much more than 30 seconds)

Tighten fittings to 18-22 ft-lbs (24-29Nm) the torque

If air remains in the system, repeat the above steps

Changing Clutch housing Oil

Detach clutch assembly

Remove inspect plug

Drain oil from check plug opening

Fill through NH 134 hydraulic oil through the check plug hole

Oil is full when oil level is in ~ the bottom the the opened for the examine plug

Reinstall check plug and clutch assembly

Oil need to be confirm after every 50 hrs and readjusted after every 600 hours

Changing the power Steering Oil

Oil drains best when engine is at operation temperature, yet not hot

Take out drainpipe plug to drainpipe oil

Put drainpipe plug back in

Turn the filter / reservoir assembly counterclockwise come detach it

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

Tighten filter until it touches the mounting surface

Tighten filter second ¾ turn by hand

Remove filler plug / dipstick and also fill the reservoir with NH 134 hydraulic oil

Put filler plug / dipstick back in

Power steering oil demands to be adjusted after every 600 hrs of use

Wheel Bolt Torque

Check wheel bolts regularly as follows:

Front wheel speak 90 ft pounds

Rear wheel torque 125 ft pounds

Lubrication Fittings

Grease the complying with points ~ every 50 hours (or an ext if operating under extremely dirty conditions)
