Valtra T133 H, T153 H, T173 H, T193 H service schedule

1. Three-point linkage: levelling screws, top link, lifting cylinder lower pins and upper pins, two nipples each.
2. Pick-up hitch and front linkage nipples; front linkage lifting cylinder pins and lifting links shaft every 50 hours.
3. Brake cam: nipples both sides with Calsium LF, plus the sliding surfaces.
4. Front axle mounting bearings: lift the front end a little (not by the axle or weight bracket), grease both bearings and tilt the axle so grease goes in evenly. Air-suspended axle: nipples on the mounting.
5. Flexible front mudguards if fitted.

Tools: Grease gun

1. Park on level ground, lower any implement or loader to the ground, apply the parking brake, stop the engine, take the key out and chock the wheels.
2. Run the engine briefly to warm the oil, then stop it. Let it stand a few minutes so the oil drains back, but wear gloves because the oil can still be very hot.
3. Remove the sump drain plug and let the oil run into a container, clean the plug and refit it.
4. Unscrew the old oil filter, wipe away any oil that ran onto the chassis, smear a little oil on the new filter's seal and tighten it by hand only.
5. Refill through the filler to the upper mark on the dipstick.
6. Start the engine, check for leaks, stop it, wait a few minutes and recheck the level on the dipstick.
7. Check that the crankcase breather pipe is open and not blocked.

Tools: Drain tray (25 L), Sump plug spanner, Filter wrench, Funnel, Rags and gloves

1. Park on level ground, lower any implement or loader to the ground, apply the parking brake, stop the engine, take the key out and chock the wheels.
2. Put a container under each filter and clean the housing and the area around it.
3. Remove the housing and element, wash the housing in diesel, oil the new element's seal and fit it.
4. Refit the housing and tighten to 200 Nm.
5. The hydraulic return filter is labelled HYD; filters are on the right of the tractor under the cab.

Tools: Container, Torque wrench (200 Nm), Diesel for washing housings

1. Grease the door hinges and the rubber surfaces of the trailer quick couplings.
2. Check the ventilation hole of the engine breather is not blocked.
3. Brake pedal free travel 45–55 mm (T133 H) or 35–45 mm (others); check the parking brake.
4. Front axle: oil level to the inspection hole in the differential and each hub.
5. Front PTO (if fitted): change the oil via the rear plug, wash the oil filter in diesel, fill to the level hole; check the rubber couplings.
6. Engine valves: the handbook has an authorised workshop adjust them after 500 hours (and then every 1,000 hours).

Tools: Ruler, Grease gun

1. Park on level ground, lower any implement or loader to the ground, apply the parking brake, stop the engine, take the key out and chock the wheels.
2. Raise and lower the lift until the oil is a little warm, then lower the lift (and front lift).
3. Remove the drain plug under the housing, drain, clean and refit it.
4. Refill by pump through the hydraulic return coupling so the oil goes through the return filter. Check the dipstick (left of the front gearbox housing) is between min and max, start the engine and recheck.

Tools: Drain tray, Pump, Funnel

1. Differential: drain at the plug, refit it and fill through the inspection hole to its level.
2. Hubs: turn each wheel until the hole points down, drain, then turn until the hole line is horizontal and fill to the hole.

Tools: Drain tray, Spanner

1. Clean around the filters and unscrew by hand (no wrench). Never drain fuel on the ground.
2. Prefilter: disconnect the water detector wire, remove the filter, move the detector to the new one, oil the O-rings with fuel, fill the new filter with fuel and fit it.
3. Main fuel filter: turn it anticlockwise off its bracket, fill the new filter, oil its O-rings and fit it.
4. Bleed the fuel system.

Tools: Container, Rags

1. Open the housing cover (one centre nut), take out the main filter (one centre nut), then carefully take out the safety filter.
2. Fit new ones and refit the cover.

Tools: Clean cloth

1. Replace the cab ventilation filter.
2. Remove the recirculation knob (not on automatic A/C) and grille, pull out the old filter and fit the new one.

Tools: Screwdriver

1. Lift the steps down, unscrew the battery holders and disconnect the battery (negative first), then take out the battery.
2. Remove the rubber cover and the filter cover (27 mm), pull out the filter parts and fit the new elements.
3. Tighten the cover to 20–25 Nm, reconnect the battery (positive first) and refit.

Tools: 27 mm wrench, Torque wrench (20–25 Nm)

1. Ring gear: grease through the access hole.
2. Toe-in: 0–2 mm.
3. Unscrew the old hydraulics breather, oil the new seal and tighten by hand.
4. Power shuttle operation: book with an authorised workshop.
5. Tighten frame nuts and bolts.

Tools: Grease gun, Tape measure

1. Park on level ground, lower any implement or loader to the ground, apply the parking brake, stop the engine, take the key out and chock the wheels.
2. Warm the oil, drain from the gearbox and final-drive plugs, clean and refit them.
3. Clean the suction strainer in diesel, change the transmission oil filters (see the 500-hour job).
4. Take off the top link to reach the filling plug behind it, fill through the cap, check the dipstick and run the engine.
5. Brake circuits use the same oil but are not drained with the transmission. Bleed each brake circuit with a hose to a container until clear oil runs, and bleed the front axle brakes too (about 0.2 L from each side).
6. Change the transmission breather.

Tools: Drain tray (80 L), Diesel and compressed air, Hose for brake bleeding

1. Open the expansion tank cap carefully (about 1.0 bar when hot).
2. Drain, clean if needed, refill with a correct mix and fit a new cap; run the engine and recheck the level.

Tools: Container (35 L), Hose
