Powertrain UMZ-417 is a classic motor with four inline cylinders placed. To activate the pistons used a common crankshaft. The motor is equipped with carburetor, contact distribution fuel supply and distribution fixture type OHV, which provides bottom location of the camshaft. Consider its characteristics and features.
The Engine UMZ-417 features an aluminum cylinder head and the housing. Cast iron liners are planted in a block through o-rings made of rubber. This design applies to negative points in the engine as reduces its strength.
Consider the power unit – this is an advanced version of the UMP-4141 has a similar configuration with the engine ZMZ-402. Differences UMZ-417 from its predecessor:
Some modifications to the engine equipped with the crankshaft 421-series, mounted without shaft seals. From ZMZ motor differ only cylinder liners, which are placed with the help of copper strips, provide additional strength of the Assembly.
Designed several variations on this engine. The most popular among them are the following modifications:

Below are the options of the technical plan of the considered powertrain:
The Engine UMZ-417 simple prevention and maintenance. Requires periodic replacement of engine oil (every 10 thousand km) and adjustment of thermal backlashes in valves timing (after 15 thousand km).
Possible malfunctions of the motor is shown below:
Carbureted engines UAZ UMZ-417 often undergo changes, which is aimed at improving the capacity of the unit. One way is to replace an existing node in the injector system. The cost of such alterations is not always justified, since it is easier to buy a new engine with distributed injection.
Among the other methods of upgrading the reporting engine note such factors as:
These manipulations will increase the power plant up to 100 horse power.
Consider the Fix of the motor is divided into current and capital repairs. In the first case is the restoration of the health of the individual parts or their replacement. The capital portion provides for full recovery of the motor values to the nominal by a full bulkhead installed. This will require disassembly of the motor.
The Reasons for the overhaul of the engine UMZ-417:
Conducting repair work with the motor, you must follow certain rules. During disassembly of the power unit it is necessary to check each item for wear and the possibility of its further operation.
Restore the working life of the engine by complete or partial replacement of worn parts or resuscitation if it is rational. Often replacement are the connecting rod and crankshaft bearings camshaft, valve seats, bushings and other the active part.
Performing repairs need to be mindful of regulatory gaps and the tension of the timing belt. The deterioration of these indicators leads to disruption of the interaction of moving parts, poor lubrication. This leads to accelerated wear of the elements. Don't forget to put labels in places further installation of usable parts.
It is Worth noting that reducing the control size also unacceptable, because it leads to deterioration in heat transfer to pistons and bushings. This leads to excessive overheating. Before starting work the power unit UMZ-417 should be cleaned of dirt and wash. The process is preferably carried out on the swivel stand.
