Toyota Land Cruiser J100 is known as one of the best off-road classic designs. However, if this car is a versatile, comfortable SUV, designed mainly for urban use, then there was a simplified version for particularly difficult conditions. Next, consider the TLC-105: specifications, maintenance, tuning.

Features

The car in question is the GX and STD starter trims of the Toyota Land Cruiser J100, separated into a separate version based on a different design. It was produced from 1998 to 2006. The car has undergone two restyling along with the main model (in 2003 and 2005). Since this modification is designed for particularly difficult operating conditions, the design was simplified as much as possible. Technically, it is an intermediate version between the J80 and J100, since many components are borrowed from the 80 series: chassis, transmission, engines, suspensions, and the bodywork is from the Land Cruiser J100.

The car was only available in African,Australian, South American and Russian markets.

As it was during production, it is now being purchased for off-road and expeditionary use. For other purposes, buying a car is impractical, especially now that this simplified version in the secondary market is more expensive than the top-end J100.

The specifics of operation necessitates a particularly thorough diagnosis of such machines upon purchase. It should be borne in mind that Toyota Land Cruiser J105 as a specialized version has a significant proportion of modified units. Tuned copies must be evaluated very carefully: how well the modifications were made and what components were used. In addition, there are few J105s on the market, so finding them is very difficult. On the other hand, episodes 80 and 100 previously enjoyed great criminal popularity. This is not typical for J105.

Rama

The frame design is borrowed from the 80 series. The body is fixed on it with twelve bolts.

Body

TLK 105 has the same 5-door wagon body as the regular Land Cruiser J100. It features unpainted bumpers and vertical tailgate flaps (except for the Australian market version). The length is 4.89 m, width - 1.941 m, height - 1.849 m, wheelbase - 2.85 m. At the same time, the chassis is slightly narrower. Externally, the GX J105 is very similar to the Land Cruiser J100, given that simplified versions of the latter were offered in Australia.

Engine

TLK-105 was equipped with two in-linesix-cylinder engines borrowed from the Land Cruiser J80:

1. 1HZ. Atmospheric 12-valve diesel engine with a volume of 4.2 liters, which was also used on the J70. Develops 129 liters. With. at 3800 rpm and 271 Nm at 2200 rpm

2. 1FZ-FE. 4.5 liter petrol engine. Its power is 212 hp. With. at 4600 rpm, torque - 373 Nm at 3200 rpm

To simplify the design, the engine control unit has been removed.

Transmission

Gearbox - 5-speed manual. Initially, the H55F was used, and after restyling it was replaced by a borrowed one from the Land Cruiser J80 R151F. The gear ratio of the main pair is 4.3 for diesel and 3.9:1 for gasoline engine.

The drive is full, with a rigidly connected front axle and a reduction gear. The axles are thicker than the 80 series, as are the axle shafts, and have five studs instead of six. The rear axle is an unloaded type (with hubs), like the Land Cruiser J100. This makes it possible to move when it breaks.

TLK-105 has up to three forced differential locks, depending on the configuration. So, STD is equipped with only a locking center differential, GXR1 - additionally interwheel, GXR2 - and interaxle, and both interwheel.

In addition, the latest equipment is equipped with a winch.

Chassis

The front suspension, unlike the Toyota Land Cruiser J100, is dependent on the 80 series. Due tothis car has a higher seating position. Rear suspension - also dependent, like the J100.

ABS is only available on the GX trim, and then only in some markets.

To ensure the same track as the J100, the TLK-105 rims with a narrower chassis due to the front dependent suspension have a convex shape. STD has forged wheels, GX has cast wheels.

Interior

Salon TLK-105 has an expanded capacity, simplified trim and reduced equipment. The first is provided with additional seats: the front passenger seat is expanded for two people, and double benches are installed in the trunk along the sides. As a result, up to 10 passengers are placed in the car. The STD has vinyl upholstery. There are no power accessories and airbags. GX is equipped with air conditioning and simple power accessories. Upholstery - fabric. The car has two stoves. In any case, the interior of the Toyota Land Cruiser J105 is more comfortable than the corresponding versions of the 80 series.

Maintenance

Due to its simplified design, the J105 is significantly more reliable and easier to maintain than the 100 series. Many breakdowns occur not due to wear and tear, but due to illiterate operation or insufficient maintenance of the TLC-105: cabin electronics glitch, steering column play, breakage of handles and locks.

Rama

The frame is stronger than the J80. And yet it is susceptible to corrosion along the welds, especially in the rear, in the area of \u200b\u200bthe cross member and spring pads. Since the designleaky, water and dirt gets inside, so you need to clean it or fill it with anticorrosive or grease.

Body

The main points of body corrosion are fenders, windshield frame, areas under bumpers, lower part of the tailgate, body attachment points, sandblasting areas.

At the same time, the presence of rust both on the frame and on the body is largely determined by the climate conditions where the car was used.

Engine

Motors are very durable. Their service life can be more than 700 thousand kilometers. However, they are characterized by high fuel consumption: 15-20 liters for a gasoline engine and 10-15 for a diesel engine.

At 1FZ-FE, you only need to monitor the oil level, change the timing chain in time and adjust the valves. The main problem is a break in the ignition coil winding inside the distributor. Please note that cars for the Japanese and Arab markets were equipped with different versions of the engine, so they are not interchangeable.

Diesel is also very unpretentious and slightly sensitive to fuel quality, especially compared to engines equipped with Common Rail. Fuel equipment can be disabled only by very low-quality diesel fuel. The main problem is chemical corrosion and cracking of the cylinder head. With proper operation, the engine makes 500-800 thousand km.

Transmission

From the checkpoint, the H55F is considered problematic. The other gearbox is quite reliable. With regular oil changes (every 40-50 thousand km), it lasts about the same as engines. Even the clutch endures 150-200 thousand km.

Often whenoperation in difficult conditions, the front axle differential and the main pair are damaged. In addition, the splined part of the front cardan suffers. Although with proper maintenance (syringing universal joints and checking the adjustment of wheel bearings every 50 thousand km), the service life of the hubs and cardan shafts is more than 200 thousand km. The rear axle hubs and the front shaft wear out first.

Differential locks can go sour.

The transfer box serves more than 500 thousand km. Its main problem is the corrosion of the drain plug and the aluminum case.

The front axle must be sorted out every 150-200 thousand km. In addition, it can bend or leak due to depressurization of the beam welds.

Chassis

The greatest threat to the chassis is forcing the fords. So, the resource of the beams reduces the ingress of water at the same time. The breathers must be cleaned to prevent leakage of the seals. In addition, after overcoming the fords, you need to inject the crosses, as with every maintenance.

The service life of the front levers and ball bearings is from 60-80 to 150 thousand km, shock absorbers - from 150 thousand km, bushings of stabilizers - 40 thousand km.

The brakes are very stressed on such a heavy car, so they wear out quickly. On the 1HZ version they are more durable.

Electronics

From electronics, headlights and generators wear out most quickly (about 150 thousand km). Especially with a large number of additional equipment.

Tuning

J105 is usually purchased specifically for off-road and expeditionary use whereits standard features are not enough. Therefore, tuning TLK-105 is very common.

Body

Off-road tuning usually involves the installation of a power body kit, including bumpers and side skirts.

In addition, it is necessary to protect the bottom with metal sheets.

For large wheels, wheel arch extensions are usually used.

The winch should be installed.

Often they mount an expeditionary trunk. Additional lighting fixtures are usually placed on it (many options have specialized mounts).

Some parts were equipped with versions for certain markets. So, the Arab modification has a ladder to the roof, a spare wheel mount and an additional 50-liter fuel tank in the rear overhang. There are also non-standard additional tanks of larger volume.

Sometimes they make a body lift by installing spacers.

Engine

Tuning of the TLK-105 modification equipped with 1HZ is very common: the diesel engine is rather weak for such a heavy car, especially if it is equipped with additional equipment. Therefore, it is often turbocharged. To do this, use a turbine from 1HD-T or ready-made kits. In any case, a more efficient fuel system and a modified exhaust will be required. It is also desirable to install an intercooler. In addition, there is an opinion about the need to replace the piston. In addition, sometimes they install a 24-valve cylinder head from 1HD-FT.

Another option is a 1HD-FT swap, which can be both easier andcheaper.

The performance of the 1FZ-FE is enough for many.

In cold conditions, a pre-heater is very relevant. In addition, you can install a heated fuel filter, as well as heating the tank and lines.

You need a snorkel to get through the water.

In order to avoid water ingress into the crankcases when crossing fords, the breathers should be raised higher.

Due to the fact that off-road tuning usually installs a lot of additional equipment that requires energy, the car is equipped with a second battery.

Transmission

Many options for modified main pairs (up to 4, 88:1) are offered for the transmission. Versions with an incomplete set of differential locks are retrofitted with them.

When increasing engine power, replace the clutch.

Chassis

Complete suspension tuning kit includes springs, dampers, tie rods and castor boards or castor kit. Lift kits provide a 2" to 6" ride height. The castor kit, which includes silent blocks of axle levers with a modified central hole, is necessary to maintain controllability, since the castor changes during the lift. There are calculated for a certain size of the elevator and adjustable options. Another option is to bring the pivot angle to the factory setting by using castor plates (spacers) over the rear trailing arm mounts. Since the stock Panhard rods will lead to a displacementbridges, use split and extended rods. In addition, you will need to install spacers between the anti-roll bars and the body.

Due to the increase in suspension travel, it may be necessary to lengthen the brake hoses by installing spacers or replacing.

When choosing off-road wheels, you need to consider that 35-inch options are considered optimal. They allow you to maintain the durability of the main pair and CV joints. When installing large wheels (often 37- and 38-inch ones are used), the resource of these elements, as well as bridges, will be significantly reduced. In any case, large wheels require an increase in clearance: 32- and 33-inch - by 2 inches, 35-inch - by 4 inches.

Often, a car is equipped with a tire pressure change system, including a compressor and a receiver.

Interior

Prepared for raids, instances are usually equipped with a radio station, and expeditionary ones - with a bed in the trunk.

The flooring is often replaced with aluminum sheet for easier cleaning.
