Longton Sakura Servicing: Engine Oil and Filters

Sakura oil filters help remove unwanted abrasive particles and fine debris from the engine, however, as the internal surface gets blocked with debris and even an oil-water emulsion; the Sakura oil pump has to work harder to circulate lubricating oil

Modern Multigrade & Synthetic Engine oil is not just a lubricant; it contains antioxidants to help resist corrosion, surfactants to hold contaminating particles in suspension and water scavengers to handle small amounts of water contamination in your Sakura Engine

Longton Brake Fitting - New Disc Brakes & Pads

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle

The brake pedal controls the Master Cylinder (a fluid filled hydraulic piston) that transfers stopping power to the brakes

Sakura brakes can last for thousand of miles depending on use and regular service

Braking increases hydraulic brake fluid pressure

Modern Sakura braking systems use hydraulic links to transfer stopping power

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc

Sakura Disc Brakes and Drum Brake Systems

Drum Brakes are an older system than Sakura disc brakes and use two half moon shaped brake shoes that move outwards during use to apply a frictional stopping force against the inside of a brake drum

Sakura disc brakes have a pair of high friction brake pads mounted either side of a brake disc

Drum Brakes, if fitted, are usually found on Sakura rear wheels

In hydraulic braking systems, braking pressure operates a slave cylinder

Hydraulic braking pressure forces a brake calliper to press the brake pads against the disc to apply the necessary stopping force

Sakura Brake Servicing - Sakura Brake Maintenance & Parts Replacement

If the Sakura brake discs warp then they should be replaced immediately

Sakura Brakes will safely function correctly without the need for replacement for many thousands of miles

Sakura brake discs will wear and need replacing eventually and should be inspected for pitting

The brake pads on your Sakura should wear first

if the Sakura brakes overheat and are allowed to cool with pressure still applied for m the brake pads/shoes then it is possible for the disc to warp.

Sakura Steering - Steering System Inspection

Common symptoms of Sakura steering alignment problems include:-
Vehicle Drift - Your Sakura tends to pull left or right when travelling in a straight line
Modern Power steering and Drive by Wire Systems do not have the same mechanical linkages between the steering column and drive wheels making it difficult to 'feel' how the steering is performing.

The tyre tread is rapidly removed from the inner or outer tyre edge of your front tyres

One of the first signs of a potential problem with your Sakura steering system is uneven tyre wear

The tyres will need to be replaced much sooner than necessary until the steering rack is adjusted to bring your wheels into correct alignment

Your Sakura steering inspection can include:-

Sakura Tyre wear and wheel alignment

Correct wheel nut torque to manufacturer's recommendations

Steering Rack Gaiter condition

Steering Linkages for wear and corrosion

Power Steering Reservoir Levels and Top Up

Correct Tyre Pressure - inc Spare

Wheel Bearings for wear - play or noise

Sakura Services Braking System Servicing and Repair

Brakes can last for thousand of miles depending on use and regular service.

Modern braking systems use hydraulic links to transfer stopping power.

The brake pedal is attached the Master Cylinder; a fluid filled hydraulic piston.

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle.

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc.

Braking increases hydraulic brake fluid pressure.

Sakura Replacement Timing Belt or Cambelt Longton

The Timing Belt synchronizes the camshaft to the crankshaft position ensuring the valves open and close at the correct time in relation to the piston. Some vehicles use a cam chain in place of the belt or a timing gear system instead

Timing belts must be replaced at a specified manufacturer's interval. The timing belt should also be inspected regularly and replaced immediately if there is any evidence of cracking or fraying cuts or excessive wear

The toothed belt connecting the engine crankshaft to the camshaft is known as the Cambelt or Timing belt

Generally Sakura belts should be replaced every 60,000 miles or less. So, if you have just bought a secondhand Sakura that has 40,000 to 80,000 miles then it is important to know if the timing belt has been replaced or needs replacing. Check the Sakura Owner's manual for your model for the recommended changing frequency

Often it is prudent to replace a combination of items associated with the timing system. Most of the needed Sakura parts can be obtained as timing kits containing the appropriate timing components; such as: Sakura timing belt
timing belt tensioners
timing belt tensioner idler roller
front lower crank shaft seal
water pump gasket

High compression diesel engines are normally interference engines

Since Sakura Timing Belts are hidden inside the engine they tend to be forgotten when purchasing a used Sakura

If the timing belt snaps it will most probably cause serious engine damage. The camshaft stops turning with some of the valves left in the open position. In a Free Running Engine there is enough clearance between a fully open valve and the piston head to avoid serious damage. In an Interference Engine there is no clearance and the engine relies upon accurate timing to keep the valves and piston head separated. With a broken timing belt; the inertia helps the crankshaft to rotate freely forcing the pistons to strike the open valves resulting in damaged valves, pistons, and possibly even damage to the cylinder head

Sakura Clutch Replacement Longton

The pressure plate comprises heavy-duty release springs, a metal pressure ring acting as a high friction surface to interact with the clutch disc, a thrust ring (or thrust fingers) for the release bearing, and release levers

Engaging the clutch forces the clutch against the flywheel transmitting power from the crankshaft to the transmission shaft

Sakura Clutch failure often occurs when one or more of the high friction surface materials wears out on the disc. Even when the pressure plate is engaged and a clamping force is applied, there is no longer sufficient friction to transmit power without the clutch slipping. Normally the Sakura clutch disc and pressure plate are replaced. Replacing the Sakura Clutch is a major operation and it is sometimes advisable to replace a number of items, often supplied as a Sakura Clutch kit:-
Sakura clutch disc
pressure plate
release bearing
pilot bearing - bushing (when required)
internal Sakura clutch slave cylinder

Disengaging the clutch acts on heavy-duty release springs to isolate the pressure plate so that the disc is no longer pressed against the flywheel

When the clutch is dis-engaged the clamping force is removed so the clutch disc spins with the flywheel and no power is transmitted

The centre of the clutch disc has a spline pattern that matches splines on the power input shaft of the transmission system

The Sakura clutch disc is, not surprisingly, a disc with each side covered in a high friction material. It is designed to engage with the high-friction surfaces of the pressure plate and flywheel. It is also designed to transmit power to theSakura transmission system

Sakura Fuel Injection Systems

Sakura Fuel Injection
Fuel injection systems mix fuel with just the right amount of air for optimal combustion & energy release in an internal combustion engine

Sakura Re-Mapping Longton
The Sakura ECU can be replaced with a programmable ECU or re-mapped to electronically alter the engine performance characteristics

EFI - Electronic Fuel Injection
The Sakura fuel injection system is controlled by a mini-computer or Electronic Control Unit (ECU) that assimilates data from a series of temperature sensors and oxygen or lambda sensors providing feedback to help optimise fuel efficiency and power under a variety of conditions

LPG Petrol or Diesel Metering
Fuel Injection systems have replaced carburetors for the accurate mixing and delivering of petrol, lpg or diesel fuel in modern Sakura vehicles

Sakura Engine Mapping
The Sakura ECU controlling engine performance is pre-programmed with software containing embedded data on engine performance for different combinations of engine speed and acceleration

Sakura Engine Oil Change

Moisture Scavengers - Detergents - Acidity Regulators
Moisture scavengers, detergents and acidity regulators prevent all kinds of contaminants degrading and abrading the internal moving surfaces of your Sakura engine minimising the effects that water, particles, and fuel combustion residus can have on Sakura performance
Once they have absorbed the maximum amount of water and other contaminants; the risk of corrosion and failure in your in your Sakura engine increases

Oil Composition
Engine Lubricating Oil is composed of hundreds of chemicals; some can interact chemically, polymerise, oxidise and break down with the extreme conditions of temperature & shear forces pulling the oil molecules apart in your Sakura engine thus, changing the lubrication properties.

Anti Oxidants
Preventing internal engine oxidation in your Sakura motor is the job of sacrificial anti-oxidants present in the lubricating oil; Anti oxidants are sacrificed to protect your engine and will eventually be depleted making it necessary to change your oil regularly

Oil & Filter Change
A new Sakura oil filter and oil change shouldn't need a specialist Sakura engineer and is minimal compared to the cost of an Engine Rebuild; with regular maintenance and routine servicing working out cheaper than disaster recover when your Sakura engine fails

Oil Change Masterclass
Keep a small amount of the engine oil used in your next oil change in a sealed container; then when you check your oil level with the dipstick you can compare the lubricity or lubricating properties of the oil against your fresh oil:- If the oil on the dipstick seems thin compared to your reference oil sample; it may be time to get an oil change to keep your Sakura running smoothly

Synthetic Oil Change - Longton
Modern synthetic oils can last longer than old petroleum based multigrades because they are more inert with a laboratory designed molecular structure and fewer natural catalytic impurities that increase oil breakdown compared to the cheaper engine oils

Oil Change Frequency
The mechanics rule of thumb with traditional multigrade engine oils used to be "change the oil every 3000 miles" but many vehicle manufacturers indicate 5000 to 7000 miles. Initially, follow the Sakura recommended oil change guidelines to ensure you validate your warranty.

Sakura Exhaust Fitting Longton

The Sakura exhaust system allows poisonous gases from the fuel combustionto vent into the atmoshpere away from the driver and cabin

Explosions from the instantaneous ignition of the compressed fuel and air igniting in the combustion chamber creat a lot of noise that needs to be silenced in the urban environment

The exhaust pipework helps muffle and deaden the noise from the fuel combustion process

Corroded exhaust pipes allow fumes and noise to escape; increasing the risk of poisonous carbon monoxide entering the cabin and significantly increasing noise making detection an easy task
