Crawler all-terrain vehicle "Yumas"

Tracked all-terrain vehicle Yumas built by Alexander from the Nizhny Novgorod region. He is on the forum site is registered under the nickname "Rainbow".

Break-in moments in the video.

Where does the name of the off-road vehicle come from? Everything is very simple. Like the USSR, it is deciphered by the first letters, so is Yumas. The first letter "Yu" is the name of the wife who gives me time to work and it suffers, "M" is the name of the daughter who was born while the project was under construction, "A" is my name, and "C" is just a family.

The performance characteristics.
The engine from the VAZ-2103.
Gearbox (gearbox) - two pieces in series to reduce travel speed.
Front-wheel drive with a bridge from the "classics".
Turns - differential from the rear axle. The final drive ratio is 3.9.
The boat is welded from sheet metal 2 mm thick, the thickness of the side sheets is 1.5 mm, and the entire top of the sheet is 1 mm thick.
Bottom of the boat: width-800 mm, length-2700 mm, height-500 mm. Add-on height 300 mm.

The windshield is made of the rear luggage compartment cover of the VAZ-2108.

The driver's seat is also automobile.

The engine from the VAZ-2103 car is removed from the engine compartment assembly with a radiator.

The base of the drive sprocket is assembled on the hub of a VAZ-2108 with disc brakes. The teeth are bolted to the sprocket.

Suspension of support wheels on balancers without shock absorbers. As shock absorbers, springs from a foreign car were used, which came in diameter.

The axis of the balancer is turned.

The brake system and steering controls are hydraulic.

The transmission consists of two gearboxes connected by a sponge clutch.

The first run-in revealed several omissions during the construction of the Yumas tracked all-terrain vehicle. The caterpillar pitch does not match the tooth pitch on the drive wheel by 5 mm.
I had to remove the tracks and wrap the drum with a layer of conveyor belt, which was previously provided for during the manufacture of the leading star. But during the assembly I just forgot to do it.

All terrain vehicle completed, coated with polycarbonate. But the failure of the glass heating thread.

You can use the factory method and seal with glue.

But there is also a folk remedy from materials that are always at hand. On the basis of varnish, nail polish will come off, a mixture of metal sawdust and varnish is made. The place where the thread breaks with zero is cleared, a layer of the mixture is applied to the glass, and a magnet is attached to the outside of the glass until the mixture dries. After drying, you can check the operation of glass heating.
