Motorcycle IZH Planet 5 and the characteristic features of the installed engine.
Two-wheeled motorcycle IZH Planet 5 engine, which developed only 22 hp. pp., throughout almost the entire period of its production, and from 1987 to 2008 it was considered one of the most common middle-class motorcycles among domestic buyers.
This motorcycle was developed and manufactured at the Izhevsk Machine-Building Plant (Izhmash), which is located in the capital of the Republic of Udmurtia. The main advantages that ensured the popularity of Izhevsk motorcycles, and not only in Russia, should be considered:
- Ease of use.
- Simplicity of design and maintenance.
- High overall reliability.
- Economical, repairable motors.
- Affordable prices.
In addition, Izhmash constantly sought to make changes and improvements in the design of its products, including the Izh Planet 5 motorcycle model and the Izh Planet 5 engine. At the plant itself, production was regularly modernized in order to improve quality. Thus, the assembly of power units, including the assembly of the IZH Planet 5 engine, was carried out at a specialized technological site.
Masses of main assembly units in kilograms
Complete frame – 27.6 kg. Engine – 40 kg. Wheel and tire assembly – 12.6 kg. Saddle – 5.7 kg. Gas tank – 5.2 kg. Telescopic fork – 11.9 kg. Stroller V M Z 9.203 – 93 kg. Stroller V M Z 9.202 – 92 kg.

Engine for the fifth model.
The Izh Planet 5 engine contains the following main characteristics and indicators:
- – two-stroke with one cylinder;
- cylinder - 345 cc. cm;
- – 72 mm;
- – 22.0 l. With. at 4800 crankshaft rpm;
- – 12 volts;
- – air;
- – contactless;
- oil and gasoline (A 76) - 1/30.
Such engine characteristics gave it a very important feature, which was to provide high traction performance at low speeds, which is important in rural road conditions.
Reasons for repair.
Complete disassembly of the Izh Planet 5 engine during repair work is carried out if damage or breakdown of the following elements occurs:
Failure of these parts can occur due to engine jamming, general severe wear, which is accompanied by increased noise during operation, as well as various knocking noises in the crankcase. In addition, repair of the Izh Planet engine with its complete disassembly is carried out when the crankshaft seals are worn out.
The presence of such a breakdown is indicated by the following points: difficult starting of the internal combustion engine, loss of power, increased smoke.
At the initial stage of production of power units, the reed valve on the Izh Planet 5 had certain technological shortcomings associated with low strength. Therefore, it quickly collapsed, its elements fell inside the cylinder, which required further disassembly and, in most cases, replacement of the Izh Planet 5 piston. After a certain time, the manufacturer eliminated this defect.
If, when operating the engine, all routine and technical maintenance procedures established by the manufacturer were observed, and appropriate technological materials and fluids were used, then it was operated for a long time, while maintaining its technical parameters.
Electrical equipment of the Izh 56 motorcycle
Motorcycle IZH-56 electrical equipment consists of a generator, a relay regulator, a headlight, a central switch, a battery, a rear light and connecting wires. The IZH-56 is equipped with a G-36 M 1 generator, the armature of which is mounted at the end of the crankshaft, and the stator is mounted on the engine crankcase. The G-36 M 1 generator differs from the G-36 M generator by the presence of a device mounted on the breaker cover. The battery is type 3-MT-7.
The PP-30 relay-regulator has a voltage regulator and a reverse current relay, combined into one device with a common electromagnet and two windings: current and voltage. Adjustment of the PP-30 relay regulator is described here in great detail. The ignition coil and breaker are similar to those discussed above. The headlight consists of a housing 1, an optical element 3 and a rim 2. A central switch with an ignition switch, a battery warning light and a neutral warning light is mounted in the headlight housing.
The central switch has a panel with terminal posts for connecting wires and a rotor with a slider. Depending on the position of key 1, which turns the rotor together with the slider, the necessary connections of lighting devices and current sources are made.
Engine modernization.
The design features of the IZH Planet 5 motorcycle are that the owner, having certain technical skills, could do tuning work with his own hands to give his motorcycle a more modern look and increase its power.
External changes consisted mainly of installing higher wings, replacing turn signals, using an individual windshield, using larger side mirrors and a number of other attachments.
Tuning the Izh Planet 5 engine was aimed at increasing its power. Such work usually began with repressing the crankshaft of the IZH Planet 5 engine, which made it possible to increase its power by 10-15%.
The next measure to increase power was to bore the cylinder to a repair size of 76 mm and modify the piston group. In some cases, a piston group from an IZH Sport motorcycle was installed.
The next step was to change the basic clutch since it could not work with a more powerful engine. For this purpose, the clutch was disassembled and the standard discs were replaced with thicker metal ones. This increased the heel area, which correspondingly reduced slippage during shifts.
For more charged versions, turbocharging was used on the engines of IZH Planet 5 motorcycles. But, no matter how well the work on modifying the IZH Planet 5 engine is carried out on your own, this still leads to a decrease in service life and an increase in the number of repairs.
Weaknesses and shortcomings of the IZH-P5 engine of the IZH Planet 5 motorcycle
Why did they stop producing the IZH Planet motorcycle in Russia? Oddly enough, the Kovrov Machine-Building Plant named after Dektyarev (ZID), as well as the former Soviet, now Belarusian Minsk Motorcycle Plant, still supply their motorcycles to the market. As for the Izhevsk Machine-Building Plant, which produces IZH motorcycles (Planet, Planet-Sport, Jupiter), the last production batch of motorcycles was produced in 2008, then, due to difficulties arising from the economic crisis, the production of IZH motorcycles was curtailed. It’s a pity, because the state could have provided assistance to the plant. At that time, Izhmash had a lot of experimental design work on promising motorcycles, both with two-stroke and four-stroke engines. I have a lot of positive memories associated with the IZh “Planet-3” and “Planet-5” motorcycles.
Any motorcycle model starting from Planet-2 gave a head start to Jupiters in terms of cross-country ability, old or new, it doesn’t matter. He didn’t sail on it, even in the taiga or in the forest, fishing or hunting. A very reliable “workhorse” with traction like a tractor, and my father and I never transported anything on it. We bought it in 1989 and to this day my father drives it, but it looks like new and makes my heart happy with its proper operation. Planet motorcycles, even its oldest models, continue to serve their owners regularly and reliably, despite the stoppage of production, there are no problems with spare parts for repairs on the market, and there is no limit to the maintainability stock. In this article, we will look at the IZH-P5 power unit of the IZH Planet 5 motorcycle, or more precisely, its technical characteristics, weaknesses and disadvantages. The IZH-P5 power unit differs from the IZH-P4 20 hp. the previous model of the motorcycle “IZH Planety-4” increased by 2 hp. power, a higher compression ratio and an engine head, the 4th model has two exhaust pipes, the 5th has one. Gearboxes differ in the number of teeth on the gears and, accordingly, in the gear ratios. Gearboxes are interchangeable.
Chassis of the IZH 56 motorcycle
The IZH-56 motorcycle chassis consists of: a frame with a pendulum fork, rear suspension, wheels with brakes and a side trailer. The frame is welded, made of steel pipes. In the steering column of frame 3, the front fork is mounted on two thrust bearings. An engine is installed in the middle part of the frame; tank. Saddles are installed on the upper rear pipe 8 and the welded edge 10. The top point of the rear suspension is attached to bracket 11. On brackets 13, a pendulum fork is installed on the axis.
The rear suspension of the IZH-56 motorcycle chassis consists of two spring-hydraulic shock absorbers and a pendulum fork. The pendulum fork is simple in design and reliable in operation. It consists of a body in which steel bushings 6 are pressed inside the main pipe 5 at both ends. Bushings 8 are inserted into the holes of the bushings, between which a spacer tube 10 is installed. Pipe 5 is sealed with oil seals 7, and to lubricate the bushings there is a press grease nipple 1. On the right A sleeve 3 is welded to the body, in which the rear brake drive lever is attached. Brackets 11 and 12 are welded to the stays, with the help of which the pendulum fork is connected to the shock absorbers. 13 strips are welded to the ends of both feathers, into the holes of which the axle extensions are installed. In grooves 14, the rear sprocket casing is installed and an axle passes through, with which the rear wheel is attached.
The front fork IZH-56 is telescopic, with hydraulic shock absorbers, mounted on two angular contact ball bearings. The main components of the front fork are a telescopic body, a shock-absorbing element and a steering shock absorber. The leg of the telescopic fork has a steel supporting pipe, which is rigidly connected to the pipe of the other leg by two bridges: on top - by an upper bridge and a threaded plug, and from below - by a lower bridge and a coupling bolt. Outside, a sliding pipe moves along the supporting pipe of the airfoil on bushings, inside which the shock absorber body is installed. The shock-absorbing element of the feather consists of a cylindrical spring 4 and a hydraulic shock absorber.
Wheels – easily removable, interchangeable, with straight spokes; have hubs, rim, spokes and tires. The wheel hub consists of two stamped discs that are welded to a hub. The right disk has a steel ring, spot welded to the disk. The bushings have splines with which the wheels are connected to the reverse gear; on the other side of the bushing, a thread is cut into which the oil seal housing with a felt seal installed is screwed. Ball bearings (No. 203, GOST 8338-57) are pressed into the holes of the bushing on both sides, and a spacer sleeve is between them. The wheel rim is made of sheet steel and its dimensions correspond to GOST 5652-57.

Modernization [edit | edit code]
Motorcycle Izh Planeta-5-01
is a further modernization of the Izh Planeta-5 motorcycle [2].
The motorcycle began production in 1989, production was completed in 2007. Some of the technical solutions for the motorcycle were licensed and were originally intended for the promising Izh-Orion model.
The electrical system uses a permanent magnet generator with a contactless ignition system that operates independently of the battery, with automatically adjustable ignition timing.
The engine is equipped with a separate lubrication system pump, which eliminated the need to prepare and use a mixture of gasoline and oil in the motorcycle’s power system.
The gearbox is four-speed with an eccentric clutch release mechanism and a reinforced motor chain.
The front wheel brake is hydraulically driven disc or mechanically driven two-cam.
The wheel suspensions use shock absorbers with improved characteristics and rebound springs, and the rear wheel suspension arm is mounted on rolling or sliding bearings.
The kinematics of the rear wheel brake drive have been changed.
"Izh Planet-6"
. Further development of Izh Planeta-5-01. The engine received a liquid cooling system, the CPG was taken from the Izh Planet-Sport engine (24.5 hp). A pilot batch of motorcycles was produced, but was not put into production.
Weaknesses of the IZH-P5 engine
More details about the weak points of the IZH-P5 power unit...
Air filter. To prevent dust from entering the engine, frequent washing and oiling of the filter element is required. Installing a paper filter would reduce the time spent on engine maintenance during maintenance and would improve the quality of cleaning the air supplying the carburetor.
The CPG wears out after 20,000-25,000 km due to the lack of water cooling.
Transmission . Over the years, due to wear and tear, the gears switch off on their own and adjustment does not eliminate the problem. In this case, it is necessary to overhaul the gearbox and replace worn out parts.
Motorcycle air purifier IZH 56
The IZH-56 motorcycle air cleaner is of a centrifugal type and consists of two cleaning elements of the same design. The elements are connected to each other by a pipe, which also serves to connect the air cleaner to the carburetor. Each element consists of a housing, in the upper part of which spiral blades are installed that direct the air flow; A dust collector is installed at the bottom, which has a lid with a hole for collecting dust. There is a rubber gasket to seal the cover with the element body and the dust collector.
Disadvantages of the IZH-P5 engine
- Loud in operation;
- Increased vibration;
- Oil sprays from the muffler;
- Long acceleration;
- High fuel consumption;
- Small resource;
- Strong return from kickstarter.
Loud operation has a negative impact on people around (interferes with rest), which causes corresponding reactions towards the motorcyclist.
Increased engine vibration is felt throughout the motorcycle, especially with your hands on the handlebars.
Oil splashes from the muffler, which, when driving, falls on the back of the driver or passenger. This disadvantage is eliminated by installing a stainless steel ladle of the appropriate diameter at the end of the exhaust pipe. The ladle should have a sector cut out in advance, which should be in the lower part when mounted with screws. This modification will prevent oil from getting onto the back, and the exhaust will be directed downward.
Long acceleration. Planet 5 with a sidecar takes longer to accelerate. The increased duration during acceleration is especially noticeable on a motorcycle with a sidecar.
High fuel consumption. The engine is not fuel efficient and the reason is primarily in the design of the two-stroke engine.
The resource is limited to an interval of 20-25 thousand km
Strong return from kickstarter. To prevent the kickstarter from hitting your leg, do not accompany the kickstarter with your foot when it returns to its original position. The impact on the kickstarter when starting the engine should be sharp and strong.
PS. Dear “Planetovod” motorcyclists! You can ask a question or add reviews and information on the weak points and shortcomings of the IZH-P5 motor in the comments.

Motorcycle engine power supply systems IZH-56
A neck is welded at the top of the tank, which is closed with a special plug. The plug is sealed with a gasket made of petrol and oil resistant rubber.
At the bottom of the plug there is a cup with a capacity of 0.1 liter for measuring oil when preparing the fuel mixture.
The gasoline tap has three positions: open, closed and reserve.
On the IZH-56 motorcycle, the power system is equipped with a K-28 D carburetor. The float chamber consists of a body 1 and a cover 4. A float suppressor 5 is mounted on the cover, and in the center of the cover there is a reinforced fitting 7 for the gas line. Inside the float chamber there is a float 2 made of thin sheet brass. A shut-off needle 3 passes through the float, which, when a certain level of fuel in the float chamber is reached, closes the hole in the fitting. The float chamber is attached to the mixing chamber using a connecting plug 38; fiber washers 34 and 37 are installed for sealing. The float chamber communicates with the mixing chamber through channel 41. The mixing chamber consists of a housing 18, into which the mixing chamber insert 29 is inserted from below, secured with a shaped nut. The insert is sealed with a fiber washer 30. A sprayer with a main jet 36 is screwed into the center of the insert. A throttle valve 21 and an air corrector 8 are installed inside the mixing chamber housing.
A conical metering needle 32 is attached to the throttle valve using a latch 20. The throttle valve and the corrector are lifted with the help of cables and returned back under the action of springs 9 and 17. The upper part of the mixing chamber is closed with a cover 12, which is secured with a nut 11. Adjustment fittings are installed in the cover shell of the throttle cable 15 and air corrector 14. In the mixing chamber housing and insert there are channels for the passage of gasoline and air 40, 24, 25, 27 and 28. The mixing chamber has two pipes: one for connecting to the air filter, and the other to the cylinder pipe . Fastening to the cylinder pipe is carried out using a clamp and a tightening screw.
