Land Cruiser 17th year major repair! Part 6, wiring, tire balance, winding

Updated: Aug 12, 2022

Last time, I introduced that the lining was completed.

This time, it will be a little different from the last time, but I will introduce the assembly work from wiring.


 



Place each board in its original location


Painting is almost complete.


While wiring the speaker cable and other cables for all electrical components, various parts were returned to their original positions.


Replace the cables around the dashboard


If it doesn't happen, the energization test is repeated.

I reconnected the cables one by one and reconnected all the cables.


Return the board from the part where the wiring work is completed.



The fan doesn't work even if I connect the cable!


When I searched for the cause, I arrived at the fuse box.




The fuse itself was not broken, but the

metal parts to which the fuse was connected were damaged.


It was broken from the base of the large amperage fuse at the bottom of the photo on the right, so I replaced it with a new one.




It's very nice to have the cluttered and disjointed parts assembled one by one, become part of the car, and clean up the interior of the car.


I was absorbed in putting back the parts one by one.

All wiring and parts were returned by the caretaker.





Confirmed that all speakers worked, and returned the board to its original location.



When the wiring was completed, all the boards were returned to their original positions.


Speakers are woofer, tweeter, and 4 other groups.

The back is a woofer.

Music can be heard well even in the back seats.


I plan to attach the floor board later when I find a good material.


All sheet surfaces are sprayed with silicon spray.



High lift jack bent after many years of use



A high lift jack that comes in handy when stuck.

It's an indispensable jack for safari.

Purchased at the same time as the start of the ride 17 years ago, and continues to this day.


It was bent after many years of use. (made in china)



Certainly a press machine up to 50 tons



It was straightened back to a level that was not visible.


When the car parts were almost assembled, I went to balance the tires.



Remove all tires at the same time and start work



When painting the wheels, all the balance weights were removed, so the tires are well-balanced.

If you put out more than 60 km / h, it will be shaken.

A total of 6 including 2 spares.


To do balancing.


All tires are biased tube tires.

It slides well on wet roads, but I like the feeling of stickiness and biting on dry rough roads.

Tires that stick well to rocks. This is probably due to the deformation peculiar to bias tires.


A combination of old leaf spring suspension system and bias tires.

Especially, the ride quality on unpaved roads is quite well-balanced.


Recently, the number of people using tubeless tires has increased in this country as well, and the number of places where puncture repairs cannot be made has increased.


The advantage of tube tires is that they can be used even when the pressure is extremely reduced, such as when you want a grip.


With tubeless tires, if you reduce the pressure too much, air will leak from the gap between the rim and the tire.

Also, even if you hit it against a rock, air often leaks between the tire and the rim.

Once it leaks, it becomes a habit.


The experience of the caretaker, the story of shooting wild animals in Serengeti.

For a while, I was using a Land Rover with tubeless tires.


One day during the shooting, it became a puncture in a row, and it became a hindrance to the shooting.

I changed to tube tires and the punk was settled.

The cause seems to be that the rim and tires were not accurate and air was leaking through the gap.



It is not possible on a general paved road, but it often happens when driving off-road.


If you understand the merits and demerits, you will understand that there are merits even for fairly old ones.


Whenever a new product is made, only the advantages are emphasized, but don't forget that there are also disadvantages!



Electric balancing machine



Surprisingly few machines can balance tires of this size and this rim



I put the two newest tires on the wheel with the least runout and used it as the front tire.


For the wheel with the largest touch, put on the oldest tire and use it as a spare tire.


The center of the balance of all wheels was put out.



The Land Cruiser that the manager made in 1991 rides is a drum brake for all four wheels!



Before returning the tires to the car, the brake drum was removed and the area around the brake shoes was inspected.


Inspect all 4 pieces in front, back, left and right.

There is no problem with the remaining thickness of the shoe.

The minimum thickness is 1 mm or more.

I still had plenty of time to spare.


No brake oil or differential oil leaks were confirmed.

The oil seal relationship seems to be okay.

Leakage begins when the oil seal is damaged.


For the time being, the surface of the brake shoe is sanded to refresh the surface.


This drum brake has some drawbacks.

It doesn't work when it's submerged, and it doesn't work when it's downhill for a long time (paper lock phenomenon).


Due to its nature, disc brakes are more popular, but drum brakes also have some advantages.


Self-boosting effect, the effect of the brake trying to tighten itself when the brake is applied. (In the event of a brake booster failure, the brakes worked properly, and I was killed.)


This self-boosting effect, an effect not found in disc brakes.

It is this drum brake that is usually used for the side brake.

There is no need to attach a drum just for the small side brake.


And since the ground contact area of ​​the shoe is wider than the disc brake, it works quite well.

Especially at medium and low speeds.

It can be seen that there are merits because it is often installed in trucks and large vehicles.


The downside is

It needs to be adjusted from time to time, and another drawback is the characteristics of the braking effect.

Suddenly strong property.

The brakes suddenly work and lock when it starts to rain, so it is necessary to take this into consideration when braking.

If you lock it, the control will not work, so release the brake immediately after locking! Then step on the brake again.

I need such a technique.


You need to be especially careful when driving at night when it rains, and sometimes bumps on the road.


Full manual without ABS.

It makes driving more technical and enjoyable.

Therefore, concentration is maintained even when driving long distances, leading to safe driving.



HZJ75, my car that has finished almost all the work


After waiting about 20 days for the paint to dry sufficiently, I polished and waxed the surface of the car body.
