Dual Mass Flywheel Replacement Kits

Posted on by admin

 


Relates To: All Dual Mass Replacement Kits
FLYWHEEL ORIENTATION
Many Dual Mass Replacement flywheels need to be installed in a particular orientation. ALWAYS check for dowel holes, timing marks or uneven bolt spacing and make sure the flywheel is oriented the correct way. Failure to do so will result in the engine miss firing or not starting.

HANDLING

Take care when handling the flywheel. Do not drop the flywheel onto the timing ring as the teeth can get damaged. If installed with damaged timing ring teeth the engine may miss fire or not start.

ELECTRONIC CONTROL UNITS
Some vehicles require the ECU to be reset after installation of a Dual Mass Replacement Kit. Failure to do so will result in the engine miss firing or not starting.

DRIVELINE NOISE

Dual mass replacement clutch kits (utilising a rigid flywheel and multi-rate clutch plate) are not as efficient at dampening driveline noises as are dual mass flywheel kits. When installing a dual mass replacement some additional noise should be expected. This noise is not detrimental to the performance or durability of the driveline components.

The Importance Of Changing The Power Steering Fluid

Posted on by admin
*|MC:SUBJECT|*

 


The power steering fluid reservoir is positioned beneath the hood, normally on the passenger side, but it can also be found on the driver's side. The container is typically white or yellow, with a black lid that says "power steering" or "steering fluid" on top.

Power steering fluid is typically red, amber, pink, light, and/or clear. If it's dark brown or frothy, it's probably time to change it.

Power steering fluid keeps the hoses, pistons, valves, and power steering pump in good working order. The power steering pump will begin to deteriorate if you do not maintain the quality of your vehicle's power steering fluid by cleansing and replacing it as needed.

Although power steering fluid does not expire, if it is not changed or flushed as necessary, it will wear down in the system over time.

When power steering fluid is neglected, it can cause harm to components such as the power steering pump and power steering rack. It is far more expensive to replace these items than to service the power steering fluid.

What happens when a vehicle's power steering fluid runs out? It will make turning the vehicle considerably more difficult. In the worst-case situation, you'll damage the power steering pump, necessitating an expensive replacement.

What Exactly Is Power Steering?
A vehicle's power steering system employs engine power to help lessen the amount of effort required to turn the vehicle's front wheels. It's a technology that gives the driver more control and management of the vehicle.

Hydraulic or electric power steering systems are available. Hydraulic systems use fluid to apply hydraulic pressure to the system, which helps turn the wheels of a car. An electronic system detects how much force a driver applies to the steering wheel using an electric motor and several sensors, and then determines how much assist the system should provide.

What Is the Purpose of Power Steering Fluid?
The hydraulic fluid utilised in the steering system to form a hydraulic link between the steering wheel and the front wheels is known as power steering fluid. This reduces the amount of effort needed to turn the wheels.

Power steering fluid additionally lubricates the steering system's working parts. It reduces foaming and prevents corrosion in the power steering gear and steering pump, allowing cars to run at peak performance.

What Are the Many Kinds of Power Steering Fluid?
The fluid used inside the automatic transmission is known as automatic transmission fluid (ATF). Certain power steering systems can also use ATF. Dexron and Mercon are two ATF kinds.

Synthetic power steering fluid is a lab-created non-oil-based fluid. Synthetic power steering fluid is usually designed specifically for the vehicle or system for which it is intended. Most contemporary automobiles use synthetic power steering fluid.

Non-synthetic, mineral-based oil power steering fluids are also available for use in applications that utilise ATF fluids.

"Is power steering fluid the same as transmission fluid?" many people wonder.

While both ATF and power steering fluid are hydraulic fluids, ATF contains modifiers and detergents that are specifically designed to remove dirt and grease from the transmission system.

When Should You Replace Your Power Steering Fluid?

When you should change your power steering fluid is determined by the type of fluid used and the amount of fluid in the system. Following the original equipment manufacturer's (OEM) instructions is the best approach to determine when your power steering fluid should be updated. In general, power steering fluid should be changed every five years or 50,000 miles.

There may be physical indications that the power steering fluid needs to be replaced. The power steering fluid should be light in colour when inspected. If it's dark, it's time to make a change. If you notice any dirt, debris, or sludge in the power steering fluid, it's time to cleanse the system.

When you spin the steering wheel, you may also hear a moaning or whining sound, which indicates that your power steering system needs to be checked. If turning the wheel becomes more difficult, this could be another clue that the fluid needs to be changed. If there are any leaks, you should also check the power steering fluid level.

To service steering wheel fluid, drain or flush the old power steering fluid from the vehicle and replace it with new power steering fluid. It is critical to service power steering fluid since it can assist extend the life of other power steering components.

When Ball Joints Wear Out

Posted on by admin
*|MC:SUBJECT|*

 

Ball joints are components found on a vehicle's front suspension system. They aid in the formation of the link between the control arms and the steering knuckles. This provides relatively smooth movement within the suspension.

The steering knuckles can travel in different directions while remaining attached to the car thanks to ball joints. This motion allows the wheels to travel up and down as needed, as well as side to side.

A ball joint is made up of a metal housing, a stud that may spin within the housing, and a lubricated socket. When you're driving, the ball stud is continually moving.

Upper and lower ball joints are available depending on the vehicle and suspension. Upper ball joints are normally non-load-bearing, whereas lower ball joints are typically load-bearing.

When Should Ball Joints Be Replaced?

Ball joints will endure daily wear and tear due to their position in the suspension system. They will need to be replaced at some point.

Because of the continual movement of the ball stud, it might become loose and move around inside the socket. As a ball joint wears down, there is more space between the stud and the socket, which can cause problems. If ball joints become too worn out, the stud can pull out of the socket and cause a wheel to become partially separated from the vehicle, putting your safety in danger.

Manufacturers frequently provide standards for the allowable amount of space between the stud and the socket, which you should get familiar with. You can also look for signs of worn ball joints, such as:
  • A vehicle pulling to one side of the road could be due to poor alignment, but it could also be a sign of worn-out ball joints.
  • Irregular tyre wear: Damaged ball joints can produce uneven wear on the inside or outside of the tyres.
  • Rattling or clunking noises: When moving over bumps or turning, ball joints that have become loose in their sockets can generate a variety of noises, including knocking, clunking, or slamming.
  • Excessive vibration: Rattling and shaking in the suspension or through the steering wheel can indicate ball joint wear and strain. 
It is critical that you send your car to a certified technician who is equipped to diagnose and repair this critical component of your suspension!

The Toyota Hilux is an unbreakable vehicle with a tough exterior, the ability to carry large loads, and a smooth petrol engine. On average, this Toyota engine will last between 250,000 and 300,000 kilometres. This means that the petrol engine in the Hilux has an average life of 14-18 years. The 3RZ-FE engine was developed in 1994 and became not only the most powerful but also the most successful example of the "RZ" series of engines. Toyota designers were able to maximise the benefits of the I4 inline 4-cylinder layout (low manufacturing cost, simplicity, and reliability of operation) while minimising its drawbacks due to the use of complex balance shafts in the design.

As a result, Toyota received a reasonably powerful and reasonably priced petrol engine, which was successfully installed on the company's light commercial vehicles for 12 years both domestically and in other automotive markets around the world (Europe, North America, Asia, and the Middle East).

To that extent, the 3RZ-FE Toyota Hilux engine is extremely dependable. Major engine components such as the block, cylinder heads, and internals are extremely durable and should never fail.

As this is primarily a commercial vehicle a heavy-duty clutch kit is a logical modification to increase durability and reliability. Clutch Industries has a range of clutch kits available including 4×4 performance kits in the 4Terrain range, the 4TUSRF1584N being the highest spec system in the range.  

4WD Clutch Kit – Ultimate Heavy-duty Upgrade
 

When a new clutch kit is installed the flywheel must be either replaced or ground. This is because excessive heat from normal driving changes the structure of your flywheel surface which creates less friction affecting the performance of your clutch. If this is not done common issues experienced are shudder and or slipping after installing the new clutch kit.

Why grind when you can replace?

There are three main technical reasons to replace a conventional flywheel instead of grinding it.

  1. Issues caused by a bad grind. There are various issues that can come out of a poor grind, these include;  (a) Flywheel surface being too smooth which can cause shutter or slipping. (b) Incorrect flywheel step or recess ground; in the case where a flywheel is not flat the recess or step must be maintained. Failure to do this can cause engagement or disengagement issues.
  2. Risk of catastrophic failure; in situations where the flywheel is placed under extreme heat damage can occur to the steel microstructure weakening the flywheel which can lead to cracking or destruction of the flywheel.
  3. Decreasing the overall stack height. Modern actuation systems have limited bearing height adjustment so after 2-3 grinds the overall stack height of the clutch system can be reduced enough to cause disengagement issues.

 

It's not uncommon for Hilux owners to modify their petrol vehicle for more extreme off-road driving and when these modifications are done it's important to also upgrade the clutch system.

How To Prevent Vehicle Rust

Posted on by admin

There is no specific age at which cars begin to corrode. Wear and tear can degrade protective coatings and expose metal to moisture over time.

Although older models were built before rust-proofing compounds were commonly employed in the production process, the most likely causes of your car rusting are due to other circumstances.

When iron combines with oxygen and water, rust forms. The oxidising appears as a reddish-brown coat, which might cause corrosion.

This type of damage typically occurs in automobiles as a result of a combination of factors:

  • Consistent exposure to rain, sleet, and snow increases the likelihood of moisture oxidising with metals on your vehicle. Salts used to grit icy roads can also hasten the corrosion process, and greater temperatures are associated with higher rates of corrosion. 
  • Paintwork and protective coatings can suffer from wear and tear over time. When metalwork is exposed to moisture, it rusts and corrodes.
  • Because older cars were typically built without non-reactive coatings, they were more prone to rusting. Arch liners are also used in newer cars to protect the wheel wells.
  • If you frequently drive off-road or through puddles, you may be increasing the danger of corrosion.

If you’re looking to buy a car and notice signs of rust you should ask yourself a few important questions before deciding whether to part with your cash.

Fortunately, there are a few things you can do to prevent rust and corrosion:

  • If you live near the sea or have been driving in bad weather, give your car a short rinse with water. A quick hose down can keep the dirt and grime of the day from accumulating on your paintwork and eventually rusting it. Just make sure to finish with a quick chamois rub over.
  • A application of wax will offer a layer of protection to your paintwork. You can also use a wax injection gun to reach regions where moisture is prone to accumulate over time.
  • WD40 or similar products are a fantastic aid in the fight against rust and corrosion. Using a smart straw to apply the solution can assist you in extracting moisture from hinges, joints, and other difficult-to-reach regions.
  • Parking your car in a garage will help protect it from the elements, but you may want to go a step further to keep it rust-free. After parking your automobile in a garage, you can use a dehumidifier to remove any moisture from the air.

Jeeps are dependable, have a lengthy history, are capable of keeping up with traffic, and have a distinct style. It is well-known for its longevity, lasting between 200,000 and 400,000 kilometres. That’s an incredible vehicle lifespan. Your Jeep can easily last between 15-20 years if well maintained, even with lots of driving and adventure.

Wrangler has a more sporty appearance thanks to removable roofs, doors, and windshields. It’s a complete blast to drive, and it handles rough roads far better than smooth ones. While you might see Wranglers mostly around the city, ultimately its designed as an offroader.

Cherokee, on the other hand, appeals to someone who wants a Jeep that can cover them both for daily driving, weekend highway trips, with the off-roading bit being on the side menu.

It’s not uncommon for Jeep owners to modify their vehicle for more extreme off-road driving and when these modifications are done it’s important to also upgrade the clutch system.

When Should Differential Fluid Be Replaced?

Posted on by admin

A differential is a set of gears that allows the driven wheels of a vehicle to rotate at different speeds when traveling around corners or over rough terrain. These gears necessitate lubrication, which is commonly referred to as differential fluid, gear oil, or gear lube. Despite the fact that modern vehicles have significantly more horsepower, torque, and towing capacity than their predecessors, the design of differential gears and bearings has remained largely unchanged.

When Should Differential Fluid Be Replaced?

The answer is determined by the manufacturer. For the proper service interval, always refer to your owner’s manual. In most cases, differential fluid should be changed every 30,000 to 50,000 miles. Because metal-on-metal contact generates heat from friction, it’s critical to stay on top of changing differential fluid. It also wears down surfaces and weakens gears. This can result in differential failure, which is a costly issue.

Differential fluid keeps the differential operating at peak performance for an extended period of time.  It is intended to perform under high-pressure conditions rather than at high temperatures, as engine oil is. It lubricates clutch packs, gears, and bearings; lubricates the ring and pinion gears that transfer power from the driveshaft to the wheel axles; and -cools and lubricates the differential.

The differential would overheat if there was no differential fluid because of metal-on-metal contact. That means it would burn out, potentially causing safety issues and necessitating costly repairs.

Differential fluids are classified into two types. Mineral oil, for example, is a natural, crude oil-based fluid. The other type of differential fluid is synthetic differential fluid, which is created in a laboratory. Synthetic differential fluid oils, like all synthetic oils, can be fine-tuned for optimal performance.

When differential fluid levels fall below a certain level, the gears begin to grind, which can lead to differential failure. Differentials do not have an oil filter, unlike motor oil, which does. Small metal shavings or pieces may appear when a differential experiences unwanted friction, causing significant damage to the differential.

LC100 was designed to provide more power than the 80 Series it replaced while maintaining the nameplate’s high levels of reliability. Furthermore, because of its longer wheelbase, it has improved passenger comfort. Despite its unremarkable design, the LC 100 provided a commanding view of the road thanks to its tall and flat front area, as if aerodynamics had never existed. Nonetheless, because it began with the 80 series to show some curved lines, it continued. As a result, the areas around the wheels on the front fenders were enlarged. On the rear quarter panels, a similar enlarged area was applied around the wheels.

Depending on the options, the interior featured either fabric or leather upholstery. The dashboard appeared to be a cross between a car and a truck, with a comprehensive instrument cluster that displayed more gauges than a standard car. Nonetheless, the center stack was not installed by truck-makers. Furthermore, the tall center console created a separate area for both front occupants. The middle row could accommodate three passengers, while the last row could accommodate two more.

Europe’s weapon of choice was the 4.2-liter inline-six turbo-diesel. In any case, it was a large vehicle that, thanks to its all-wheel drive system and two-speed transfer case, could still handle off-road situations well.
