For many years Hobbies of technical creativity as the main source of materials and machinery for me was a different sort of scrap yard. Out in my shed “migrated” all that seemed valuable to me, and was waiting for their application to varying design. Unclaimed gradually accumulated, and eventually the question arose: what to do with it? Would not go. Here and decided to maximize all these different glands in your new tractor. Design “Angara” started with a sketch drawing of the design. Then, after the detailed execution of working drawings, started construction. The result was, in my opinion, quite aesthetically pleasing, technologically advanced and reliable machine, with a reserve for possible future upgrades.


The cab did not do for the following reasons.


First, it is designed to operate only in the summer, although it has sufficient versatility and has a record for various mounted and trailed implements.


Second,the driver-mechanic quite often have to stop the car, quickly leave and re-occupy their workplace. In such cases, the cabin him hindrance.

Thirdly, for the effective and safe operation on a small plot of good all-round visibility from the seat, which again is not in favor of the cab. However, over the seat, if necessary, you can install a simple canvas awning on a tubular rack — the design of the tractor is provided.

What is “Angrez”?

The main bearing element design “Angara”, like any other tractor is a powerful force frame with multiple brackets, which are attached to almost all the basic mechanisms and units of the tractor. With her and began the manufacture of my car.


The FRAME has a rectangular shape and is welded from two longitudinal side members and three cross-beams, reinforced walls, and various scarves.


Front and rear beam made of channel in the form of boxes, tanks, equipped with water necks with screw caps and drain valves. In these tanks is stored an extra supply of fuel.



To the front beam of the bottom are welded two thick steel plates with holes — loop suspension Assembly of the front axle, and the top ears of fastening of facing of a radiator and guiding hand crank (for starting the engine manually).


The walls of the front member for greater rigidity are connected by three cross-cutting varname bushings with internal thread М14х1,5 screw fastening ring (front). The ring here — not only hitch: it also serves as a bracket for mounting of some attachments.


All the frame are located in different places seven mounts for these guns. Four of them (in the corners of the frame) formed by a continuation of the channel walls of the side members at the front and rear beams and are reinforced on both sides by powerful fatty washers.


The average beam welded from sheet metal and is mainly intended for attaching some elements of the hydraulic system and lever of a manual brake.

In the design of a tractor “Angrez” for effective vibration control is used numerous rubber mounts and bushings-shocks. In particular, the pillow includes an engine, transmission, transfer case and frame radiator. Dampers are the struts of the frame of the radiator, frame, fuel tank, instrument panel sockets installation of the hood.


The DRIVETRAIN of the tractor. It uses transmission units scrapped cars of famous brands. Transmission with PTO — GAS-53. Torque from it through the universal joint assembled from two flange plugs and crosses from the GAZ-51 is transmitted to the transfer case from the GAZ-66. Driven shaft “transfer case” is used as a braking device (it is put on a drum hand brake), and — if necessary — for extra PTO.


The torque from the transfer case to the rear axle is transmitted through the universal joint, similar to that described above. Moreover, the hinge is attached to the shaft drive… front axle “transfer case”. To make this possible, the drive shaft is modified: the front splined section is cut and moved back that is welded to the rear end of the shaft. For this purpose, the welded joints were made deep chamfer, and welding was carried out in a jig, where the item is cooled to cool and finishing on a lathe. The thus obtained Val successfully works already more than one year. Of course, it would be better to carve the necessary detail and slice it slots, as the saying goes, “new”, but my technical capabilities did not allow for that.


ENGINE. As I had diesel pflanzenol execution, who has worked for ten years on water transport, one had to adapt it to the coast guard. In particular, to establish inentionally air filter, add a closed crankcase ventilation system, replace the sea water pump drive pump GP-10, to alter the controls decompressionmethods and fuel pump and so on.

Just the design of the engine made more than twenty all kinds of changes. The most difficult and time consuming was the installation of clutch and connection of the transmission to a flywheel housing of the engine. These problems were solved in the following way.

Instead of regular nuts of fastening of a flywheel installed new combination nut with pressed into her closed ball bearing, which is now part of the front end of the gearbox shaft.

The flywheel housing of the engine is enhanced by the so-called doubler, welded from sheet steel, the outer dimensions of which correspond to the internal dimensions of the casing. The doubler has a flange with threaded holes for the bolts securing the clutch housing from the GAZ-53. Flywheel housing with inserted therein a backup is attached to the crankcase with screws, the heads of which scontrini circle soft steel wire.


On the tractor installed tnodes – big deal grip from the GAZ-51. Due to the fact that the engine flywheel is hollow, the clutch cover had to be fixed to it via a special adapter — thick steel washer. I had to carve under it in the rear end of the flywheel of the landing recess with a diameter equal to the diameter of the casing of the clutch. For joint fixing washer, clutch casing and flywheel to the body of the last performed blind threaded holes for the screws.

When you install the clutch housing and mixed nuts of fastening of a flywheel I used the fixture for centering the axis of the shaft. (Description not cite, because it is not original. More or less experienced Amateur designers, tend to have device not worse.) Flywheel Assembly with clutch subjected to careful balancing.


TRANSFER BOX is suspended under the middle beam of the frame of the tractor on two special brackets that serve at the same time covers technological hatches Carter “transfer case”. The brackets are welded mainly of sheet steel of different thickness, and the holes attaching them to the box drilled. In addition, the right bracket has an axis for the lever for the PTO, at the transmission.

FRONT AXLE — wheels from UAZ. Balancer axle is made of steel tube section 80x80x6 mm long, the ends of which with longitudinal and transverse slopes respectively 3° and 5° welded cups pivot bearings 206 and 8207. Two pairs of king pins and axle shafts machined separately, then connected by welding. The pivot bearing is lubricated through the grease fittings as needed (bearings of the wheel hubs — only before installing it on the axle).
In the suspension unit of the front axle used roller bearings 2206. This increasing complexity is due to the scarcity in our area bronze. However, destruction of these bearings even in the most severe conditions was not.
The hub and drives the front wheels of the car GAZ-69 Swivel arms improvised, forged, with subsequent machining and metal processing. The camber is constant (2°), incorporated in the design of the front axle. Convergence is governed by their shortened tie rod from the GAZ-51.
The FRONT WINGS are homemade, with rubber mud flaps. Back — factory made tractor T-20 but with a partially changed the mounting brackets.
REAR AXLE of the car GAZ-53 (with shortened housings axle shafts). Wheels — ZIL-157 as the most suitable for the operating conditions of the tractor. Main gear — from GAZ-66, as its Cam limited slip differential eliminates slippage one of the wheels that increases the permeability “of Angara” for damp, sand and arable soil. To the frame of the tractor rear axle attached ladders.
Alteration of the bridge (shortening the rod casings) made at home. The process sequence was as follows.
From Carter bridge, I drained the oil. Dismantled the axle, the hub and main gear. From the factory the welds connecting the axle with cover measured to the center of the length of the deleted sections. Line cutting firebreaks along the perimeter superchanel and arable soils.

From Carter bridge, I drained the oil. Dismantled the axle, the hub and main gear. From the factory the welds connecting the axle with cover measured to the center of the length of the deleted sections. Line cutting firebreaks along the perimeter of the storage-
bill to a depth of 1-2 mm, to better see them in the blinding light of the gas torch. And gently separated first axle, and then shortened the shrouds.
After complete cooling cleaned the place from cutting slag. Missed through the crankcase long stud, for all put it on the axle with the guides and gently tightened the nut. Tapping the axles hammer plumbing, installed them in the middle section casings, controlling the size of the caliper. Tightened the nut to the end of the first tack, and then multi-pass and symmetric welding seams (to reduce warpage of the structure) was finally connected with the axle housings.
Pinch the pin with guide bushings dismantled after the complete cooling of the metal.
Thick and rigid walls of a crankcase of the rear bridge allowed me to place any additional equipment in the form welded to the brackets, support pads and loops.
BRAKES. The tractor is equipped with two braking systems: a hydraulic working acting on rear wheels, and a mechanical handbrake operating on the transmission (transfer case). The first brake system — entirely from GAZ-53, second from GAZ-51.
THE TRIGGER SYSTEM OF THE ENGINE. Unfortunately, diesel engine, mounted on “Angara”, has a difficult start. It takes time for preheating the spark plug even at positive temperature of air on the periodicity of the starter and so on. Therefore, the use of standard electric starter ST-15 and warm candles require this engine battery with a capacity of not less than 75-180 Ah.
Buy a battery I was expensive, and I chose a different, unconventional way of starting the engine — with the use of asynchronous three-phase motor power 1,5 kW (at 2850 rpm) power supply 380 V Mounted together with bracket-casing left on the frame of the tractor, it through a chain transmission with a gear ratio of I = 1 rotates the composite cushion pad of the device, and that, in turn, the flywheel of the engine crankshaft.
The starter consists of housing (front cover starter ST-15); head (of a glass bearing 60205 and an integral cushion on which you sit, the driven sprocket, clutch, starter gear, thrust washer and bronze bushing bearing); switch with a lever and a pusher (anchor of the traction relay of a starter ST-15); arm rocker.
Engine “Angara” starting system installed on the place of the regular starter.
The engine is started in the following way. The socket electrical connector on the frame of the tractor, I connect the cable plug from the special remote control, and wire the circuit warming up the candles — to the terminals of the electrical shield on the tractor. Only after that connect power cable control panel with power supply of 380 V.
On the remote triggered automatic switch and light bulb circuit warm-up candles. On the engine is ready to start judging by the control element on slack-troxide, the intensity of which indicates the degree of heating of candles.
By hand turn the lever of the switch, and enter the starter gear fully engages with the ring gear of the flywheel on the crankshaft of the engine, and leg press the button on the remote control and switching on the motor. As a rule, a good warm candles the engine starts immediately. Then I unplug the console from the mains.
So as to power the starter motor used life-threatening stress, I have taken all the necessary safety precautions. Namely, the power to the panel is via a circuit breaker of the series A-3100; a power transformer through the circuit breaker of series AB-25M; all connecting cables are four-wire in a metal braid; the tractor’s chassis, remote control, motor and cables are properly grounded.
When the engine of the tractor, standing on the open ground, the remote provides an additional device in the form of a removable ground pin. The pin is inserted into the socket of the panel, fixed by a wing nut and all the way stuck in the ground.
The control panel is welded from steel sheets 2 mm thick in a rectangular enclosure. It has a removable bottom cover, side ventilation louvers. Automatic inclusion of the power transformer and the signal light bracket is protected from mechanical damages. Connecting cables and conductors insulated from the sides of the chassis by rubber bushings. Inside, a removable housing cover mounted machine AB-25M, power transformer TR-OSO-0,25, and magnetic starter, PME-211.
The magnetic circuit of the transformer additionally is wound 16 turns of insulated copper wire 14 mm2. Remove them with a variable voltage of 12 V serves as a power electrical circuit of the heating candles.
Of course, the method of starting the engine is quite complicated, but for me it was a way out. Now, when on the “Angara” installed everything needed for normal operation of the tractor electrical equipment, you can easily go to the start using the starter. And the mounting bracket of the starter motor to use to install the platform under the battery.
A HYDRAULIC SYSTEM. Tractor mounted hydraulic system designed to control the driver’s workplace all mounted and semi-mounted implements. It includes the valve, gear pump HLU-10, power cylinder, oil tank, piping low and high pressure valves
The hydraulic pump with the actuator attached to the crankcase timing gears of the engine through a homemade reducer that increases the nominal speed of the pump 1.2 times. Drive allows you to turn on the pump with one hand.
Gear drive used slightly modified gears and shafts from the transmission of the motorcycle “IZH-56”. In the case of a reducer welded from galvanized sheet steel, filled with gear oil TAP-15V.
The valve R75-23 three-piece. Constantly working on one section, the other two only when mounting additional equipment.
The hydraulic power cylinder from the combine harvester. Cylinder rod with adjustable forks and the finger is connected with the pivoting arm of the hinged device.
Oil tank is structurally designed at the same time with the right Polikom that four bolts M10 attached to the respective brackets on the frame of the tractor. For reliable operation of the hydraulic system all input and output connections of the tank are provided with filters.
