Tag: 1HZ LC100 1/99-On; 4Terrain

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.

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 LC100 owners to modify their diesel Landcruiser’s for more extreme off-road driving and when these modifications are done it’s important to also upgrade the clutch system. For these enthusiasts, a clutch modification that can handle greater torque while also increasing heat dissipation and providing a superb pedal feel is essential. 4Terrain has been engineering different options for Landcruisers for decades, one of the most popular products being in the 4Terrain Ultimate brand.
