The fluid replacement process for the Kubota B7200 is the same as it is for most of the other Kubota B-series tractors. The fluids that require changing consist of the engine oil, transmission oil and the front axle case oil. The fluids protect the moving parts inside of each component by preventing heat friction. The fluids are essential to prolonging the life of the tractor. Change all of the fluids at the proper intervals as recommended by the Kubota B2700 owner’s manual. Once the fluids break down, they will not be able to properly protect each component.

Things You’ll Need

• Wheel chocks
• Drip pan
• Protective gloves
• 1/2-inch drive socket set and ratchet
• Torque wrench
• Oil filter wrench
• Oil filter

• Funnel
• Engine oil
• Nonflammable solvent
• Transmission fluid filter
• Transmission fluid
• Front axle fluid

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.

Tips & Warnings

• All of the fluids can be added with a single funnel. Clean the funnel after each use.
• All of the fluids, filters and filter wrenches for the Kubota B7200 can be found at most all tractor supply stores or tractor parts stores.
• Refer to the tractor’s owner’s manual for exact fluid amounts and proper changing intervals.

• Always use caution when working around a hot engine to prevent serious burns. Wear protective gloves if necessary.
