Kubota M5091 Transmission Troubleshooting

(1) Transmission is making noise

Nasty backlash or gears that are worn out. Install the new gears and make sure the backlash is correct. Shift forks are broken or worn down.

Shift forks should be replaced. The splines on the shaft are broken or worn. Change the shaft. Transmission oil is insufficient.

Add oil to the housing of the transmission. Bearings that are worn or broken. We need to change the bearings—transmission oil contamination. Switch out the oil.

(2) Hard Shifting

Gear shift linkage that is worn or rusty. Change the linkage that moves the gears—misaligned or worn clutch. The clutch needs to be fixed or changed. Shift forks are broken or worn down. Switch the shift levers. The mechanism for changing gears is broken. Parts that are broken must be replaced.

There needs to be more oil pressure and a low transmission fluid level. I was checking the transmission fluid level and adding more if needed clogged transmission oil filter elements (if fitted).

The transmission filter should be cleaned or changed, and the stuck relief valve should be. As needed, change the relief valve.

(3) External oil leaks

Gaskets or seals are worn out. Replace seals or gaskets that are worn. The transmission fluid level is too high. Drain off the extra liquid.

Kubota M5091 Steering System Troubleshooting

(1) The steering wheel has too much free-play

Most wear is on the steering column rod or coupling. Change the broken part. The problem is with the hydraulic steering pump.

Check this same steering pump and, if it needs to be, replaced it. The assembly of the steering linkage is worn out or loose. Check and make changes as needed.

The control valve for the power steering is broken or worn out. Check and change as necessary.

(2) Stiff steering

Steering system air. Exhale clogged steering filter. Fix or replace the steering filter—more steering fluid. Fill the steering fluid appropriately.

The power steering valve is broken. You can fix or replace the steering control valve—a broken hydraulic steering pump. Replace the steering pump.

You are steering a blocked pump control valve. Replace and clean your control valve broken or misassembled steering column. Rebuild or replace the steering column—uneven tire pressure.

Change tire pressure. Unadjusted toe-in. Toe-in properly. Steering cylinder leaks. Worn piston rods or cylinder seals.

(3) The tractor is pulling to the left or right

The control valve for the power steering is worn or broken. Check and make changes as needed. The steering cylinder has been damaged. The steering cylinder needs to be changed or fixed.

Not adjusted toe-in. Correctly set the toe-in—loose as well as worn steering linking components. Check and make changes as needed.

The bearings in the front wheels are worn or set up wrong. Correctly adjust or replace the bearings—uneven tire pressure. Fill the tires upright.

Kubota M5091 Engine Troubleshooting

(1) The engine starts hard or doesn’t start

Fuel filter plugging. Replace the filter element—the atmosphere in the fuel system. Bleed fuel system. Fuel injection nozzles blame. Spray nozzles should be cleaned or replaced. The fuel injection pump has been broken. Replace or fix the pump that injects fuel.

(2) Diesel shuts off while driving

The timing is off on the fuel injection pump. Set up the way it’s told—dirty fuel filter. Change the element of the filter. The engine needs to warm up more. Start the car’s engine.

(3) Diesel starts and stalls immediately

The fuel filter was plugged in. Fix the filter or get a new one—fuel injection pump harm. Put in a new compressor or fix the old clogged filter element. The air filter needs to be taken care of.

(4) Engine overheats

The radiator core is dirty, or the radiator cap is broken. The clean radiator as well as replaced cap. There needs to be more coolant in the system.

Fill up the coolant and look for any leaks. Fan belt that is broken or worn. Change the fan belt—low oil level in the engine. Put oil in the crankcase of the engine.

(5) Poor engine power

The fuel injectors are broken or dirty. You can change the injection nozzles—dirt in the lines or hoses that carry fuel if you need to. Clean the fuel lines and hoses. The air cleaner is not plugged in. Clean it or get a new one—damaged cylinder-head gasket. Change the gasket on the cylinder head.

(6) Strange noises from the engine

The engine has yet to warm up. Get to the right temperature—more oil in the engine. Check the oil level and add more if needed—incorrect fuel injection timing.

Change the timing of the fuel injection pump in the right way. The pistons are broken or worn out. Have the pistons changed? The connecting rod is broken or out of place. Connecting rods must be replaced or put in the right place.

(7) When the engine stops idling

The setting for low idle speed needs to be corrected. Make the right changes. More room between the valves. Get it changed. The problem is with the fuel injection pump. Put in a new compressor or fix the old one.

(8) Low oil pressure

More oil. Oil is needed—oil pump failure. Fix or get a new one. Able to plug engine oil filter. Customer support or change motor oil filter element.

Kubota M5091 Hydraulic System Troubleshooting

(1) The hydraulic system got too hot

The type of hydraulic fluid needs to be corrected. It is essential to use the right kind of fluid. It contaminated hydraulic fluid.

Change hydraulic fluid air in the hydraulic system. Seep atmosphere from the hydraulic system—faulty relief valve. Replace the relief valve.

(2) The pressure of the hydraulic fluid is low

There needs to be hydraulic fluid. As needed, add water. The hydraulic oil filter seems to be complete. If you need to, replace the filter element and clean it.

Hydraulic piping has been leaking. Look for leaks in the system and fix them. A hydraulic control valve needed to be set up right.

Fix things right. The hydraulic pump still needs to be fixed. Change or fix the oil pump for the hydraulic system damaged hydraulic cylinder. Repair or replace the hydraulic cylinder.

(3) Hitch either doesn’t go up or goes up very slowly

Hydraulic pump malfunction. Repair or replace the hydraulic oil pump. The primary relief valve would be defective. The relief valve should be changed.

The block for the hydraulic spool valve is broken. Fix or change the valve. The hydraulic cylinder has been broken. Change out or fix the hydraulic cylinder.

There needs to be hydraulic fluid. As needed, add a water filter element for dirty hydraulic oil. If you need to, replace the hydraulic chamber or have it serviced with too much weight on the hitch. There should be less to do.

(4) You can’t drop the hitch, or it drops too slowly

The hydraulic cylinder has been broken. Put in a new cylinder or fix the one you have. A hydraulic control valve needed to be set up right.

Fix things right; the worn cross shaft of the hitch. Switch the shaft out. The hitch was not adjusted. The three-point hitch needs to be changed.

(5) Jerky hitch drop or lift

Hydraulic oil that was tainted. Change hydraulic oil faulty hydraulic pump. Replace or repair the hydraulic fluid pump. There is air stuck in the hydraulic system.

Let the air out of the system’s faulty hydraulic shaft valve. Fix or replace the hydraulic valve broken hydraulic cylinder. Replace or repair the hydraulic cylinder.

Kubota M5091 Electrical System Troubleshooting

The clamps on the terminals need to be changed. The battery is broken. I need to change the battery. The belt is old or too loose. Replace the belt, as well as adjust the belt tension.

(2) Slowly, the starter turns

Low capacity of the battery. The battery has run out, so charge it. The battery won’t stay charged. Fix or replace the battery: cables that aren’t connected or wrong terminals. Connect the wires in the right way or switch the terminals.
