The length of the all-terrain vehicle is 3000 mm.
The width of the all-terrain vehicle is 1600 mm.
Caterpillar 400 mm wide.
Ground clearance - 400 mm.
Independent suspension: unequal balancer at the rear and a lever in front.
Track rollers - wheels 155R13LT-6 pcs.
The idler is active.
The frame is from a profile pipe, and the lining is made of ST3 metal with a thickness of 1.2 mm boat, and 1 mm up the all-terrain vehicle.

Tripport hydraulic brakes.
There are two seats, the waterline passes while swimming along the upper branch of the caterpillar.

The theoretical minimum speed is 3 km \ hour, almost a little more than about 5 km \ hour.
Maximum speed for 30 km \ hour.
The left engine is located at the rear of the stern.
Right engine.
Driver's seat. No control levers. There are pedals.
Passenger or navigator seat. The seats are taken from the boat, very durable.
The all-terrain vehicle goes mostly straight. Only occasionally need to taxi.
The reverse is up to the clutch, and the clutch is belt and therefore it was necessary to make the belt preload evenly with left-right rotation.
Profile A belt, one on each side.
Initially, there was one countershaft, torn apart by a cam clutch. The cam clutch has its drawbacks: the inability to turn on under load,
shock loads when turned on at speed. Then the shaft was broken by an electromagnetic clutch, but then two independent intermediate shafts remained on each side.
The nose of the ATV is empty.
In the stern there is a place for a buter and spare parts.
The chassis is a simplified version of the TT-4 suspension. The uneven balancer.

Some flaws were revealed after the break-in.
I cut the key on the left intermediate shaft and on the drive shaft. Moreover, all 8 keys were made of one piece of metal 10HSND, shaft St40, asterisk-St3.
Asterisk could be removed only with a grinder. Left-hand side.
The right side is whole.
Leading asterisk.
The all-terrain vehicle is repaired and ready for the next test. The dowels are made of high quality metal, the driven sprockets are installed 2 more teeth, which increased the gear ratio. Lengthened the chain and tension is done by moving the engine.
Installed tension on final drives.
The right tensioner is redone (wedge) and the tensioning mechanisms are covered with covers.
The holes for the silencer are made oval, taking into account vibration.
Taped the entire all-terrain vehicle Shumkov. Redid the gas control levers.
Management became clear and obedient. Turning radius 10-12 meters. Withdrawal from a straight line on a single engine 10-15 degrees.
Chinese shock absorbers sank and therefore the course became tougher. Engines overheat in a closed housing.
Another break-in on a snowy field began. video.

The all-terrain vehicle turned out to be very successful. We wish good luck to Alexei in his endeavors.
