Daihatsu has been in the market for many decades since 1960. The long existence in the market without being kicked off by the market forces is that this minitruck delivers beyond its owner’s expectations. It has earned a good reputation and recommendations. The manual transmission Hijet is common in the market and serves better those who love driving a vehicle with three pedals. Three in this context represent the brake, the accelerator, and the clutch. All manual transmissions have a clutch pedal.

Overview Of The Clutch System

The clutch plays the role of coordinating the driving and the driven shafts. It can cut the power supply to the driven shaft when the engine is on. It also facilitates gear changing. When a driver feels the vehicle is demanding new gear shift. They press the clutch pedal to cut the power supply to the driveshaft for the gear to engage smoothly. The clutch does backbreaking work that exposes it to wear and tear. You must understand how your Hijet behaves when the clutch is worn out. In this guide, we will focus more on what you should be looking out for to do a Daihatsu Hijet clutch replacement.

Sings That You Need To Do Daihatsu Hijet Clutch Replacement

When the clutch becomes faulty, you will see the following signs from your Daihatsu Hijet.

Inverse Proportionality in the Rates at which both the Engine and the Daihatsu Hijet are Moving

You will realize that the engine will move faster, but your mini truck will move slowly. It occurs when the clutch slips and cannot generate enough friction. It is friction that turns the flywheel, and inadequate friction will make the clutch to strain to produce energy, which will result to the feeling of more power in the engine and less power transferred to the wheels. When the pressure plate is damaged, the clutch is likely to slip.

Grinding Noise

You will feel this sound when you step on the clutch pedal, resulting from the problem with the pressure plate or the release mechanism. When you press the clutch pedal, it should be able to release the Clutch. If the pedal cannot remove the Clutch, you will feel the noise because the gears will grind each other as they change. If this happens, you will have to change the entire clutch assembly.

The Daihatsu Hijet is not Able to Pick Up Gears

If you realize that your mini truck cannot pick a new gear whenever you engage, it indicates that the Clutch is developing problems. In this situation, the mini truck will likely retain the previous gear when you try to change or go to neutral whenever you change. It might be a problem if your Clutch works with the hydraulic system. Other causes of this could be the clutch disk or pressure plate.

Conclusion

The clutch is an integral system of a Daihatsu Hijet and any other manual vehicle. It does cumbersome work, which wears and tears out. Listening to any of the above signs of a faulty clutch is necessary. Doing this will help you to save your Clutch from further damage. Never repair the Clutch alone unless you have the experience required. Always involve your mechanic.

A universal joint, popularly known as U joint, is that part of your Daihatsu Hijet that makes it possible for the rotating crankshaft of the engine to transmit the rotating motion to the rear wheels. The U joint offers a flexible connection at the end of the driveshaft, making it possible for it to make an up and down motion at a particular angle to the engine as the Daihatsu Hijet is moving on various road surfaces. Different materials like stainless steel, brass, or any alloy that can withstand the high temperature and torque from the engine, as well as the materials like thermoplastics which can resist rust and corrosion, are used to make the U-joints. In this guide, we will go through some of the things to watch out for and know when to be replacing a u-joint in a Daihatsu Hijet.

Functions of a Universal Joint

The U joint connects two shafts in an inclined position. They rotate the Kei truck’s rear wheels by transmitting the rotation motion from the engine to the rear wheels.

The role of the propeller is to send power to the rear wheels despite the difference in the transmission height and the rear axle. Universal joints are used both at the propeller’s front and back parts.

The universal joints enable power transmission, and the rotary motion as the axel moves up and down because of the irregular driving surfaces.

The crucial role played by the universal joints might make them loose or faulty.

Signs of a Bad U-Joint 

The Daihatsu Hijet will give the following signs when the U-joint is faulty.

Squeaking Sound When Your Minitruck Starts a Forward or Reverse Motion

All bearings of the U-joint are lubricated at the factory. As your Daihatsu Hijet uses them, the grease concentration reduces, and their lifespan reduces. The reduced grease on the bearings makes the U-joint produce a squeaking sound when your mini truck starts to move. This sound is a warning that you should service the U-joint.

The Minitruck Vibrates on Forward Motion

The vibration indicates worn-out bearings, and the driveshaft can no longer move outside the rotational path. The frequency of this vibration is high compared to the vibration due to poor wheel balance. The U-joint can damage other parts like the transmission if it is not solved.

Leakage of Transmission Fluid

You will notice that the transmission fluid leaks from the rear transmission because of a bad U-joint. If you experience the leakage, it shows that you ignored the vibration, and now the transmission output shaft seal is worn out.

Dislocated Driveshaft

You will see trucks parked beside the road with the driveshaft below them. This results from a failed and broken U-joint; therefore, the driveshaft fell on the road. If this happens, the repairs become costly because you will need to replace the entire driveshaft. The dislocated driveshaft is the ultimate end.

Conclusion

Daihatsu Hijet has two parts that aid in transmitting power from the engine to the rear wheels. The engine produces power for moving the Daihatsu Hijet minitruck. The U-joint facilitates the rotation of the driveshaft as it transmits power to the rear wheels. As it works, it wears out with time. This guide has stressed common signs experienced by Daihatsu Hijet when the U-joint is faulty.
