How to Change Fluids on Other Vehicles

by Contributing Writer; Updated June 12, 2017

The Trucks other is a heavy duty automatic Trucks other designed for larger Trucks other. Changing the fluid is not the same as changing the fluid in a regular car or Trucks other. The system is more prone to metal chard and debris getting into the Trucks other. Flushing the fluid rids the system of all the old Trucks other fluid and any debris that is caught up in the Trucks other. Your Trucks other will be able to get any job done for many miles by regularly flushing and changing the fluid on a regular basis. Do not forget to replace the filter at every fluid change as well.

 How to Change Fluids on a Kubota B7200

Changing the Engine Oil

Park the Kubota B7200 on a level surface and turn the tractor off with the transmission still in gear. Place the wheel chocks in front of both rear wheels and behind both rear wheels.

Slide under the front of the engine and locate the two drain plugs on the bottom of the two engine oil pans. There is one oil pan on the left-hand side of the engine and one oil pan on the right-hand side of the engine. Place a drip pan under one of the drain plugs.

Loosen and remove the drain plug with a ratchet and a socket. Wait for all of the oil to drain out of the oil pan, and screw the drain plug back into the bottom of the oil pan. Tighten the drain plug down tight with the ratchet and socket. Torque the drain plug between 25 and 35 foot-pounds with a torque wrench and a socket.

Move the drip pan under the other oil pan drain plug. Loosen and remove the drain plug with a ratchet and a socket. Wait for all of the oil to drain out of the oil pan, and screw the plug back into the pan. Tighten the plug with the ratchet and socket. Torque the plug between 25 and 35 foot-pounds with the torque wrench and socket.

Move the drip pan under the oil filter that is located on the driver side of the engine. Loosen and remove the oil filter with a oil filter wrench. Place the oil filter into the drip pan. Spread a small amount of oil around the gasket of the new oil filter. Tighten the new filter with the filter wrench until the filter is tight. Once the filter is tight, turn the filter another half of a turn with the filter wrench.

Remove the oil cap from the side of the engine. Insert the funnel into the oil fill tube. Pour 2 qts. of the new engine oil into the fill tube. Check the oil level on the dipstick. Continue adding the new engine oil until the oil level on the dipstick in on or near the upper groove on the bottom of the dipstick. The upper groove is the "full" groove.

Crank the engine and let it idle for about 30 seconds. Turn the engine off and recheck the oil level on the dipstick. Add more oil if necessary until the oil level is on the upper groove of the dipstick.

Changing the Transmission Fluid

Place the drip pan underneath the four drain plugs on the bottom and sides of the transmission case. There are a total of four drain plugs on the bottom of the transmission case. One drain plug is on the front of the transmission case, one drain plug is on the back of the transmission case, and one plug is on each side of the transmission case.

Loosen and remove one of the transmission case drain plugs with the ratchet and a socket. Wait for all of the transmission fluid to drain out of the transmission case, and screw the plug back in to the transmission case. Tighten the drain plug down tight with the ratchet and socket. Torque the transmission case drain plug down to between 30 and 40 foot-pounds with a torque wrench and a socket.

Remove drain plugs one at a time from the transmission case until the transmission fluid has been drained from all four drain plugs. Torque each of the transmission case drain plugs down to between 30 and 40 foot-pounds with the torque wrench and a socket.

Slide the drip pan under the transmission case strainer bolt that is located under the transmission fluid filter on the driver side of the engine. Remove the strainer bolt with a ratchet and a socket. Clean the strainer with a nonflammable solvent. Once the strainer is clean, screw the strainer bolt back into the bottom side of the engine. and tighten the strainer bolt down tight with the ratchet and socket. Torque the strainer bolt down to between 30 and 40 foot-pounds with the torque wrench and socket.

Loosen and remove the transmission fluid filter with the filter wrench. Unscrew the transmission filter and place it into the drip pan. Spread a small amount of transmission fluid around the seal of the new transmission fluid filter and screw the new filter onto the side of the transmission. Tighten the filter down tight. Once the filter is tight, turn the filter another half of a turn with the filter wrench to properly seat the new filter to the transmission housing.

Remove the transmission dipstick on the side of the engine. Insert the funnel and pour 3.8 gallons of the Kubota Super UDT transmission fluid into the transmission. Remove the funnel and replace the dipstick. Check the fluid level on the dipstick. The fluid level should be on the upper mark of the dipstick. Add more fluid if necessary.

Changing the Front Axle Case Oil

Place the drip pan under the driver side front axle drain plug. Pull the filler plug out of the top of the driver side front axle case with your hand. The filler plug is also the dipstick. Lay the fill plug on the tractors seat.

Loosen and remove the drain plug with a ratchet and a socket. Wait for all of the axle fluid to drain out of the driver side of the axle case, and screw the drain plug back into the bottom of the front axle case. Tighten the drain plug with the ratchet and socket. Torque the front axle case drain plug down to between 30 and 40 foot-pounds with a torque wrench and a socket.

Move the drip pan under the passenger side of the front axle case. Pull the filler plug out of the passenger side top of the front axle case and place the fill plug on the tractor's seat.

Loosen and remove the passenger-side axle case drain plug with the ratchet and socket. Wait for all of the fluid to drain out of the passenger side of the axle case and screw the drain plug back into the axle case. Tighten the drain plug with the ratchet and socket. Torque the drain plug down to between 30 and 40 foot-pounds with the torque wrench and a socket.

Fill up each side of the front axle housing from one of the the fill plug holes with the new axle oil. Reinsert the fill plug/dipstick, and wait about five minutes for the axle oil to fully drain throughout the front axle housing on both sides of the front axle case.

Pull the dipstick out and check the fluid level on the dipstick. The fluid level should be on or near the upper groove. The front axle case holds approximately 4.7 qts. of axle oil. Add more axle fluid if necessary.

Remove the wheel chocks from the rear wheels. Move the drip pan out of the way of the tractor. Crank the engine and drive the tractor around for about 10 minutes. Turn the engine off, and recheck all of the fluids that were changed. Add more fluids if necessary.

 How To Change Fluid On An Allison Transmission

Draining the Transmission Fluid

Park the truck on a flat level space and make sure the parking brake is set.

Place a large drain pan underneath the transmission. Locate the drain plug at the bottom of the transmission drain pan.

Unscrew the drain plug with a socket wrench. Allow all the fluid to drain out.

Locate the cooler return line which is labeled "From Cooler". The lines are located next to the transmission filter. Pull the retaining clip, out of the way with a small flat head screwdriver. Pull the line out and place a 5/8-inch plastic hose over the line. Insert the other end of the line into a gallon jug.

Unscrew the transmission filter with an oil filter wrench. Pull the filter down and take the magnet off the top of the filter. Clean any debris off the magnet and place it on the new filter. Fill the filter with automatic transmission fluid and lubricate the gasket. Rub transmission fluid around the gasket with your fingers. Tighten the filter back to the filter housing by hand. Do not wrench tighten as this will strip the threads of the filter.

Flush and Filling the Transmission

Open the hood to access the transmission fluid fill pipe. Take the dipstick out and insert a funnel into the fill tube. Pour 8 quarts. of the recommended transmission fluid in to the funnel.

Make sure the hose is sunk into the fill bottle. You may need a partner to help by instructing them to start the truck so you can watch the bottle. You will need to be sure that no more than 2 quarts of fluid gets pumped out into the tube. Turn off the truck when 2 liters have flowed into the gallon container. Dump the 2 liters into the waste transmission fluid. Replace with an additional 2 liters of transmission fluid into the fill tube.

Place the hose in to the gallon container. Be sure to set the brake and then start the truck. Engage each gear while holding it for one second. Bring the shifter back to the park or neutral position and turn the truck off. Make sure you do not lose more than 3 liters of transmission fluid to the container.

Dump the old transmission fluid out and replace with 3 liters of new transmission fluid. Repeat the process one more time to be sure the transmission fluid coming out of the return line is clean. Replace any fluid lost.

Push the cooler return line back to the transmission. Make sure you place the locking ring back toward the top of the line to lock it in place.

Check to be sure the fluid level reads full. If not add more fluid a liter at a time. Drive the truck for at least an hour and check the fluid one more time to be sure the level is accurate.

Items you will need

  • Socket wrench

  • Socket set

  • Drain pan

  • 16 liters transmission fluid

  • Flat head screwdriver
