CUMMINS Corporation has long been renowned for its durable engines dating back to 1919. During its existence, CUMMINS employees have made it clear that they are the reliable suppliers of diesel engines with great potential and at the same time low fuel consumption.
Let's try to figure out how the GAZ Valdai model changed after they began to produce these cars with the CUMMINS ISF3.8 diesel engine, what is so "unusual" about these engines, and what is the fuel consumption at Valdai with a Cummins engine.
Scope of the truck
Its main application is the transportation of various cargoes, small-sized and overall dimensions, with a total weight of not more than four tons. It is also possible to install various special equipment on the car platform: tarpaulin, manufactured goods vans, refrigerators, crane-manipulator installations, and side bodies of various sizes.
The GAZ-33106 tow truck, as well as vehicles equipped for the transportation of bakery products, have become widely used, as they have excellent maneuverability and small overall dimensions. This greatly facilitates movement in urban areas.
Based on the foregoing, it can be noted with confidence that the domestic GAZ-33106 truck is rightfully a universal medium-duty vehicle with a wide range of applications. And both in terms of equipment, and in terms of terrain features.
GAZ-33106: specifications and reviews
This car is equipped with a Cummins ISF 4-cylinder diesel unit with a displacement of 3.8 liters, whose power is 150 horsepower. At the same time, reviews note low fuel consumption - at a speed of 80 kilometers, only 15 liters. The drive is carried out by transmitting torque to the rear axle. The curb weight of the truck is 3325 kilograms, and when loaded - 7400 kilograms.
The area of the cargo platform is 7.6 square meters. Reviews say that the car has high maneuverability. This is evidenced by the minimum turning radius - 6.7 meters.
Opinion
RUSLAN YAKUBOV, individual entrepreneur Moscow
- The Valdai car with the MMZ-245 engine has been working with us for the seventh year already, but the total mileage is still small - only about 40 thousand km. A car with an onboard tented body, loads - the most diverse, except for food. We travel mainly in Moscow and the region, but there are also orders for flights to neighboring regions, including those on bad roads. Nevertheless, the undercarriage of the car has not yet required repairs - no backlash in the pivot joints of the front axle and steering linkage joints was found during the last inspection. The engine and transmission are also in perfect working order. Of the little things, I note the periodically falling voltage of the generator, as evidenced by the sharp deviations of the ammeter needle. But so far there has been no critical discharge of the battery. The tires on the front wheels have already had to be replaced with Cormoran of the same size, while the rear wheels still have native ones. Fuel consumption on the highway is about 16 l / 100 km, in the city - about 20 l / 100 km.
Modernization and improvement
A considerable amount of work was carried out in 2010 to improve and modernize the car, a set of measures aimed at improving the performance and characteristics of the GAZ-33106 Valdai was translated into reality. The main stage of modernization was the equipping of the car with a new Cummins diesel power plant, which made it possible to expand the technical capabilities of the already popular truck. At the same time, judging by the reviews, fuel consumption has decreased by 10 percent, which plays an important role in our time. The cab of the car is equipped with a new radiator grille, a modified bumper, which consists of three parts, and plastic expansion pads on the wheel arches are installed. In the process of improvement, the cab interior received an updated interior and a modified instrument panel, which can be seen in the photo, as a result, driving became more comfortable.
Reviews note a reliable braking system. It is equipped with pneumatics, and ventilated disc brakes are installed on the wheels of both axles. Through the use of such a drive, it became possible to operate a truck with a trailer. Motorists say that the car can reach a decent speed, which is 100 kilometers per hour, which is quite enough for a truck of this class. Cruise control, power steering, anti-lock wheel system are attached to the basic configuration of the car. Regardless of what type of cargo the car carries, it has excellent stability on uneven roads and a noticeable softness.
Fuel consumption of CUMMINS ISF3.8 engine
The consumption rate for Valdai with Kamens engines ranges from 14 to 17 liters per 100 km. According to official figures, if the engine power is set to 154 hp, then at a constant speed of 60 kilometers per hour, the car will require 12 liters of diesel fuel, and at a speed of 80 kilometers per hour, this figure will be 15 liters.
By the way, when compared with the “export Valdai”, the GAZ-3310 consumption rate on the Minsk MMZ-245.7 engine at 60 kilometers per hour is 13.5 liters, and at 80 kilometers per hour - 18 liters.
To summarize: the GAZ-3310 Valdai car can rightfully be called the “pride” of the Gorky Automobile Plant. At the same time, it is the model with the CUMMINS ISF3.8 engine that is the most practical, combining both low operating costs (including fuel consumption) and a long motor resource with a reliability guarantee of up to two years.
At the same time, the price for Valdai is lower than for Korean trucks, by about 20-30%! This car is worth the money spent on it, so it's time to support the domestic manufacturer in the current situation.
dimensions
Due to its size, Valdai can easily move around in urban areas, transporting oversized cargo, while not obstructing the movement of other vehicles. The dimensions of the transported goods largely depend on the modification of the model and which cabin is installed on the chassis. So, depending on the purpose, it can be equipped with various types of cabins, which ultimately affects the usable loading area and dimensions of the car:
- Single row cab:
- Length - 6100 mm.
- Base - 3310 mm.
- The mass of a car with such overall dimensions is about 4100 kg.
2. Triple cab:
- Length - 7760 mm.
- Wheelbase - 4000 mm.
3. Triple cabin without a berth:
- Length - 7800 mm.
- Wheelbase - 4200 mm.
The height and width of all modifications remains unchanged and is equal to 4000 and 2400 mm, respectively.
As you can see, the overall dimensions of the GAZ-33106, as well as the usable area for cargo, vary depending on the cabin installed on it.
Specifications (late 2010)
- The cabin can accommodate three people or six people in a two-seater version.

Transmission
The car is equipped with a Sacs single-plate diaphragm clutch, which has a high degree of reliability and ease of maintenance. At GAZ, a five-speed gearbox with a power take-off drive operates in tandem with the engine.
Its body is cast from aluminum, which significantly reduces the total weight of the machine. But at the same time it has sufficient operational strength. The rear axle is equipped with a unit from the Soviet GAZ-53 truck with a slight change in gear ratio. Most of the transmission elements are interchangeable with elements of machines of this brand.
Modifications
In fact, there were only six of them, not counting the piece pre-series, equipped with GAZ-562 and IVECO 8040.45C engines - three with each of the engines. The use of the MMZ engine adds the number 4 to the GAZ-3310 designation, and the number 6 to the Cummins engine. If there are no more numbers, then these are short-wheelbase modifications with a 3.5-meter body. The appearance of an additional number 1 at the end of the marking indicates a long base, an elongated rear overhang and a body length of 5 meters. The number 3 in the same position indicates the Farmer modification with a two-row cab, a long wheelbase and a 3.5-meter body (see table). But these are only their own, factory cars. And there are also a lot of tax-like "stretch marks" that hundreds of organizations (including little-known ones) registered as vehicle manufacturers have the right to issue. However, in practice, about a dozen reputable rebuilders are seriously involved in the re-equipment of medium-duty vehicles, whose design and technological capabilities are boldly trusted by both dealers of domestic car factories and importers of foreign cars. The trailer LLC (Stupino, Moscow Region), known for its trailers, went the furthest in finalizing Valdai, where they created a three-axle modification with a carrying capacity of 5.5 tons with an air suspension of a “sloth” drawbridge - the benefit of compressed air from a compressor at Valdai enough. Such machines are needed, but so far they are exotic.
The first three years of production at Valdai were equipped with a Minsk 4.8-liter MMZ-245 engine in Euro-2 performance - with mechanical fuel injection, that is, equipped with an in-line high-pressure fuel pump and digesting low-quality fuel without problems. Since 2008, the Euro-3 engine has gone - with much more sensitive to impurities and very expensive Common Rail equipment from Bosch. The designation of the engine remained the same - MMZ-245.7, which cannot be said about the filling: many of the most important parts have changed, including pistons, connecting rods, piston pins, etc. At the end of 2010, the Chinese-made Cummins ISF3.8s3154 engine went to the assembly of Valdai cars, of course , also with Common Rail and also meeting Euro-3 requirements. For about six months, both engines were available, and then, from the beginning of 2011, only Cummins began to be installed on cars for the Russian market. The four-cylinder 3.8-liter unit with a declared resource of 500 thousand km is assembled on a non-sleeved cylinder block, has a rod drive of sixteen valves and a chain drive of the lower camshaft from the flywheel side. The chain is with an automatic tensioner, its durability is enough for the entire life of the motor before overhaul. Valve clearance adjustment is traditional - a screw with a locknut, the frequency is every 240 thousand km. High pressure fuel pump drive - gear from the front toe of the crankshaft.
Switching to Cummins made the car much more comfortable - the cab became much quieter, idle vibrations were gone, and fuel consumption decreased by about 1 l / 100 km. It is curious that the transition to modification 33106 was accompanied by an increase in the declared carrying capacity from 3.5 to 4.0 tons. Although the car initially, and with the Minsk engine, too, was physically four tons - the extra 500 kg was crossed out only on paper so that the buyer would not fall under the requirement to license transportation. On June 2, 2005, this was canceled by federal law, and the need for camouflage disappeared, but GAZ, by inertia, continued to advertise Valdai as a 3.5-ton vehicle for another five long years.
Chassis
Truck frame elements are made of high-strength steel by stamping and riveting, which affects the high load capacity and endurance.
Spars with a variable profile size are the main component of the frame, which is used as a basis in all models of this car brand, regardless of equipment. To increase the overall dimensions, it is possible to use special frame inserts in the spars, which are fastened with rivets. Thus, it is possible to change the length of the frame for a certain type of platform.
Such work can be carried out both at the factory and at firms that specialize in re-equipping cars of this brand.
GAZ-33106 is equipped with stamped steel wheels, rim size 6 / 17.5 mm, and tires 216/75 with a diameter of 17.5 ′, which is very convenient in terms of operation and interchangeability.
Model Benefits
Due to the fact that this car has established itself as a reliable and economical workhorse, with the ability to perform various types of work and transportation, even in the secondary market, the GAZ-33106 Valdai used has a high cost and competitiveness.
Indeed, unlike foreign cars of this class, it is easy to maintain and repair, spare parts and additional equipment are readily available and much cheaper than spare parts from foreign manufacturers.
So, we found out what characteristics the GAZ 33106 Valdai truck has.
