Modifications
Based on the dump truck, numerous modifications were created for various tasks. There are non-standard modifications, for example, armored army ones. Next, the most popular car modifications will be considered.
Car Ural 55571-40
Dump truck with rear unloading based on the original model. Used for transporting construction waste, sand, soil and other construction materials. The main difference from the original model is the load capacity increased by three tons.

Main characteristics of the car
| Length, mm | 7735 |
| Width, mm | 2500 |
| Height, mm | 2980 |
| Load capacity, kg | 10000 |
| Maximum loaded weight, kg | 20775 |
| Engine Variation | YaMZ-236NE2 |
| Engine power, l. With. | 230 |
Fire truck
Modification of the original model, three-axle tanker AC 5.5 40. Used for fire fighting. It has characteristics that are almost identical to the base model in almost all respects. The dimensions have changed (now they are 8000 x 2500 x 3400). A fire installation has appeared that can accommodate six cubic meters of water. There is a foam block with a capacity of 360 liters. Pump capacity is 40 liters per second and higher.

Dump truck
The car was originally a dump truck, but currently the 55571-44 modification with dimensions 8170x2500x3275 mm and a YaMZ-236NE2 engine is most often used as a dump truck. The model has a double all-metal cabin with a sleeping bag.

Farmer
For more convenient use in agriculture, the Ural 5557 is sometimes equipped with a hydraulic body lifting mechanism, which also allows unloading in two directions - this is most convenient for bulk cargo. Usually the Ural model 5557-8603043 mechanism is used. Models with this mechanism are called “agricultural machines” and one of the most popular is the Ural 5557-10 with a load capacity of 6745\16500 kg.

Relays and fuses
URAL relays and fuses are located in the cab on the mounting block to the right of the instrument panel under a removable cover. The serial number of fuses in the list corresponds to their numbering on the blocks.
1-relay for unloading terminal “15” (P2); 2-starter relay (P1); 3, 4, 6, 8, 9, 11 - fuse blocks; 5-relay for unloading terminal “15” (R3); 7-windshield wiper relay (R4); 10-rear fog lights relay; 12-diagnostic connector; 13-relay pneumatic brake signal switch (R12); 14-mirror heating relay (R11); 15-stop signal relay (R10); 16-horn relay (R9); 17-high beam relay (R8); 18-low beam relay (R7); 19-side light relay (R6); 20-relay additional rear fog lights (R5).
CAR ELECTRONICS REPAIR
General information
The electrical equipment system is single-wire, the negative pole of power sources and consumers is connected to the vehicle ground.
The sources of electricity are two batteries connected in series and a generator operating in conjunction with a voltage regulator. The connection of units and electrical equipment is carried out using wires with polyvinyl chloride insulation of various sections. The wires included in the bundles are made of a certain color to make them easier to find and easier to install. Single wires can be made in any color. The color of the wire can be indicated on the cuffs installed at both ends of the wire, the first letter of the color. The wires are connected to each other and connected to devices using plug connectors.
The car is equipped with a mechanically driven speedometer, electronic instruments and systems: tachometer, generator with a rectifier unit, etc. To avoid breakage of the flexible shaft of the GV300-05 speedometer, when installing and dismantling the instrument panel, lay the flexible shaft in such a way that the mark painted on shaft shell, was located outside the cabin directly behind the sealing sleeve of the flexible shaft passage hole, while the flexible shaft must be routed without forming a loop behind the instrument panel.
For reliable operation of these devices and systems, it is necessary to monitor the condition of the fuses installed in the blocks. Do not use non-standard fuses in the form of bent wire, bolts, washers, since in the event of a short circuit in the electrical circuit this will lead to immediate failure of electronics-based products. A blown fuse should be replaced with another one of the same intended operating current.
