Owner reviews and prices

YaMZ - from 250,000 rubles;
Renault - from 350,000 rubles;
Mercedes - from RUB 550,000;
MAN - from 250,000 rub.

Stanislav, 42 years old, Tver: “I worked at MAZ with a Chinese engine for about three years. I recommend not saving, but immediately buying a good and powerful motor, because... The Chinese one breaks down every 2 weeks. For example, you can buy a dump truck with a Cummins engine.”

Peter, 53 years old, Penza: “I installed a Tutaev engine on a MAZ-55102. The equipment works well, without failures, oil does not leak, fuel consumption is low. The unit weighs about 12,000 kg.”

Vasily, 35 years old, Ulyanovsk: “I worked at MAZ with a YaMZ engine for 4 years. The unit is unpretentious in maintenance, all spare parts are freely available on the market. During the entire period of operation there was only 1 breakdown - oil leaked in the gearbox.”

Grigory, 46 years old, Lipetsk: “Before buying, I recommend checking the labeling so as not to buy a Chinese fake. At YaMZ, the number is located in the upper part of the cylinder block housing.”

Maxim, 48 years old, Magnitogorsk: “I worked at MAZ with a Mercedes engine for 2 years. This is a powerful unit, but maintenance is expensive. Fuel and oil must be of high quality, otherwise breakdowns will immediately begin.”

How to distinguish a new YaMZ engine from one that has undergone a major overhaul

We guarantee the factory origin of the engines presented on the site!

The easiest way to distinguish a new factory YaMZ engine from a repair one (a YaMZ engine after a major overhaul) is by the block number.

In the engine block number (also known as the engine number), the first digit is the year of manufacture; in 2022 it looks like K0ХХХХХХ, in 2022 it looks like J0ХХХХХХ. There cannot be new engines with other numbers!

Previously released engines:

H0хххххх - engines manufactured in 2022
G0хххххх — engines produced in 2016

B0хххххх — engines produced in 2011
A0хххххх — engines produced in 2010
Fully digital numbering - engines produced before 2010

The block number on six and eight-cylinder engines is stamped on a special ebb. The ebb is located in the flywheel area, on the left under the intake manifold. On counterfeit engines, the ebb with the block number is often painted over or sanded down. A metal plate (nameplate) is attached to the camber of the cylinder block in the area of the fan drive.

The ebb for the block number on twelve-cylinder engines is located in the flywheel area, on the right under the intake manifold. On counterfeit engines, the ebb with the block number is often painted over or sanded down. A metal plate (nameplate) is attached under the left intake manifold, opposite the ebb with the block number.

The block number is duplicated on the nameplate with the YaMZ engine marking (nameplate). An example is the YaMZ-650 engine (the plate is installed on the cylinder block on the left side in its middle part).

Information on the plate: 1. Trademark of JSC Avtodizel (YaMZ) Yaroslavl Motor Plant. 2. Mark of conformity with the national standard and code of the authority that issued the certificate. 3. Mark of compliance with the requirements of the Special Technical Regulations. 4. YaMZ engine model and its equipment. 5. The year when the YaMZ engine was produced, indicated by the last digit of the year of manufacture, where 9 is 2009. YaMZ engines of 2010 are designated by the letter A. 6. Serial number of the YaMZ engine.

The year of manufacture and engine number of the YaMZ 650 are duplicated on a plate attached to the block on the right side in its middle part.

The designation of the electronic control unit on the YaMZ engine and its number are indicated on a plate attached to the control unit housing.

The model of the high pressure fuel pump (HPFP) of the YaMZ engine and its number are indicated on the plate attached to the fuel pump housing.

The designation of the turbocharger and its serial number are indicated on a plate attached to the compressor housing of the YaMZ engine.

Particular attention should be paid to the issue of factory origin if you are purchasing an engine for agricultural purposes - these engines are not subject to registration with the State Traffic Inspectorate and their unscrupulous suppliers most often pass off repair ones as new ones.

Reliability, problems and repair of YaMZ-238

The YaMZ-238 series was put into production in 1962 and replaced the YaAZ-206.
This engine has a V-shaped 8-cylinder cast iron block, with a camber angle of 90°, with cast iron wet liners and with the cylinder rows offset relative to each other by 35 mm. Inside the block, a forged crankshaft with a piston stroke of 140 mm and a main journal diameter of 110 mm and a connecting rod journal diameter of 88 mm is installed on 5 supports; the connecting rods themselves are steel, and their length is 265 mm. For these engines, cast aluminum pistons with a diameter of 130 mm and a height of 100 mm were used, with a piston pin diameter of 50 mm. The cylinder block is covered with two cast iron heads with 8 valves each. The diameter of the intake valves is 61 mm, the exhaust valves are 48 mm, the stem diameter is 12 mm. A gear drive of the camshaft is used here, and the camshaft itself is located in the cylinder block and, through pushers, steel rods and steel rocker arms, actuates the valves. Camshaft characteristics: phase 246/266, lift 13.5 mm. Valve adjustment on YaMZ-238 (turbo and atmospheric) is carried out after every 500 hours of operation (if necessary). Valve clearances for both intake and exhaust are 0.25-0.3 mm. The adjustment order is 1–5–4–2–6–3–7–8, the same as the order of operation of the cylinders (both turbocharged and naturally aspirated). These engines use direct fuel injection with fuel injection pump 80-30 (on YaMZ-238M2) or with other pumps (modifications are described in detail below). Nozzle pressure 261 - 230 kgf/cm2; nozzles 267 - 270 kgf/cm 2. The oil pressure on a warm engine should be within 4-7 kgf/cm2 (this applies to both turbo and atmospheric).

In addition to atmospheric variants, turbocharged ones were also produced, the list of which knows no bounds. The main differences between them are listed below.

This motor had a related series YaMZ-236.

The production of 238 continues to this day, but they are being replaced by more environmentally friendly YaMZ-7511 and YaMZ-658.
