Motorcycle IW Planet 5 It is deservedly considered a legend of the domestic motorcycle industry, and its durability depends largely on the condition of key components, among which the generator cover occupies a special place. It is this element that protects the electromechanical part of the engine from water, dust and dirt, ensuring stable operation of the ignition and battery charging system. Any malfunction or leakyness of this part can lead to serious breakdowns, so understanding its design and principles of operation is necessary for every owner of a classic motorcycle.
In this article, we will take a detailed look at the generator cover, look at the typical problems faced by motorcyclists, and provide step-by-step maintenance instructions. Quality sealing And the right clearance adjustment is the key to making sure that your bike starts in all weather and runs smoothly for miles, and we'll also talk about upgrades, because standard solutions are sometimes inferior to today's.
Before starting disassembly or repair, it is important to realize that the generator cover is not just a piece of metal, but a complex unit that requires careful attention. On IZH Planet 5, the generator cover also serves as a support for the kick starter lever, which creates additional mechanical loads on its mounts. Ignoring this fact often leads to licking of the thread or the appearance of cracks in the places of attachment of the axles.
Design features and structure of the node
Generator cover on IW Planet 5 It's an aluminum alloy cast piece that's attached to the cartridge on the left side of the engine, and it's got the basic elements of the ignition system inside it: the stator, the rotor (anchor), the spark moment sensor (SMI) or the breaker, and the engine start mechanism, and it's designed to be service-friendly, but over time, the materials lose their properties.
The most important element is the seal. Between the lid and the crankcase of the engine is installed. paroniteThe condition of this gasket is critical: even a microscopic break can cause the engine to start sweating with oil or, worse, water to get inside the crankcase when crossing the fords.
- 🔧 The main purpose is to protect the generator and ignition system from the external environment.
- 🔧 It serves as a reference node for the axis of the kick starter lever and the bushing.
- 🔧 It contains holes for wiring and installation of adjusting screws.
Inside the lid are also bearings or bushings in which the crankshaft rotates. the tightness of this unit is ensured by a coil installed in a special seat. Deformation of the lid or wear of the seat under the omentum is a common cause of oil leakage, which is difficult to eliminate without replacing the part or using sealants.
Manufacture materials
Cast aluminum has good thermal conductivity, but soft. When the bolts are tightened, the thread can easily get damaged, so it is recommended to use a dynamometer key or be more accurate.
Typical malfunctions and methods of their diagnosis
Operating a motorcycle in difficult conditions often leads to characteristic problems. One of the most common is leakage. Owners notice oil leaks in the bottom of the lid or around the mount bolts. This can be caused by both wear and tear of the gasket. land-plane deformation The lid itself.
Another common problem is the kick starter mechanism, which causes the lever axle to be under heavy loads, and causes the seat in the lid to break or the sleeve to wear out, causing the lever to skew, making it difficult to start the engine, and causing the start mechanism to fail quickly. Diagnosis requires visual inspection and check of the axle backlash.
⚠️ Warning: If you find a crack in the area where the kick starter axis is attached, the motorcycle is prohibited, and the vibration of the engine will cause the lid to quickly collapse and metal shavings to enter the engine.
Also worth noting is the state of the electrical contacts: oxidation of the wires going through the lid to the generator often causes a spark to disappear or the battery to undercharge, wires can be rubbed on the edges of the holes, which creates a risk of short circuit.
Removal and installation of generator cover
To perform a quality repair or replacement of the gasket, you need to properly dismantle the lid. The process does not require complex tools, but requires carefulness. Before starting work, be sure to drain the oil from the engine to avoid spilling it when removing the part.
First, unplug the battery's sub-plate terminal and remove the wires going to the generator. Then unscrew the bolts of the lid around the perimeter. It's important to twist them evenly, diagonally, to avoid skewing. After removing all the bolts, gently apply the lid with a screwdriver, trying not to damage the landing plane.
☑️ Checklist of dismantling
The new lid or the old one is installed in reverse order. surface-cleannessThey should be free of any old sealant, oil or dirt, and the new gasket should be smeared with a thin layer of oil or sealant for a better fit.
Gaps adjustment and ignition system maintenance
After the lid is installed, the ignition system must be adjusted. IW Planet 5 With the contact ignition system, this means that the correct gap between the contacts of the interrupter is set up. The optimal distance should be 0.35-0.45 mm with maximum cam dilution.
To adjust, use a probe and a key to rotate the generator anchor. Relax the screw of the fixed contact and move it to get the desired value. Then tighten the screw securely and check the gap again, as it can change when tightened.
| Parameter | Normative value | Tool. |
|---|---|---|
| Clearance of contact | 0.35 - 0.45 mm | The spike is flat |
| Bolt tightening moment | 6 - 8 Nm | dynamometer key |
| Angle of advance | 2.5 - 3.5 mm before TMD | Indicator/Lampoline |
Remember to check the condition of the capacitor, which is also attached to or near the lid. its malfunction leads to burnout contacts and unstable operation of the engine at high revs. Checking the condenser It is carried out by a multimeter in the resistance measurement mode.
When assembled, lubricate the thread of the lid mount bolts with graphite lubricant. This will prevent the bolts from boiling and make it easy to remove the lid next time without the risk of tearing the edges or breaking the bolt.
Replacement of oil and elimination of oil leaks
One of the main causes of loss of compression and engine contamination is the wear of the crankshaft coil installed in the generator lid, which is a sign of malfunctioning when oil is released through the sapoon or leaks directly from under the lid. Replacement requires accuracy and knowledge of technology.
To replace, you need to knock out the old omentum. This should be done carefully so as not to damage the seat. The new omentum is recommended to be lubricated with engine oil before installation and pressed evenly, without distortion. The use of the hammer is allowed only through a wooden shelf or a special mandrel.
⚠️ Warning: Never install a dry oal. This is guaranteed to damage the working edge when the engine starts and recurs after a few hours of operation.
If the seat under the ossuary in the aluminum cover is worn out or has a production, a simple replacement of the seal will not help, in such cases, either a replacement of the entire lid, or the use of repair bushes, or the use of special high-temperature sealants to seal the pairing.
Tuning and modernization: transition to electronic ignition
Many owners IW Planet 5 They decide to upgrade the motorcycle by installing a contactless ignition system (FIS), and the standard generator cover allows for such an upgrade with minimal modifications, instead of a interruptor, they install a Hall sensor, and a magnetoconductor is attached to the rotor.
The benefits of this solution are obvious: there is no need for constant adjustment of the gap, spark formation improves, the engine operates more stable in all modes, and electronic ignition is less sensitive to moisture, which is important for the generator cover.
- 🚀 Increase the power of the spark and the stability of the engine.
- 🚀 No mechanical wear of the contacts of the interrupter.
- 🚀 Simplification of service and increase of service interval.
When installing the BSP, it is important to choose the right switch and ignition coil compatible with the generator. OLIOften used ready-made kits designed specifically for domestic motorcycles, which are easily mounted in regular places.
The transition to electronic ignition is the most effective way to improve the performance of the IL engine of Planet 5 without deep interference with the design of the CNG.
Frequently Asked Questions (FAQ)
How often should the generator cover be changed?
Re-use of the old gasket, even if it looks whole, often leads to oil leaks due to loss of elasticity of the material.
Can I use a sealant instead of a gasket?
It is not recommended to use only a sealant instead of a gasket. The best option is a new gasket, lubricated with a thin layer of sealant on both sides for better sealing of irregularities.
Why is it licking the lid mount bolts?
This is due to vibrations, moisture and the use of low-quality bolts, and it is recommended to replace the regular bolts with high-quality hardware and their condition.
How to check the integrity of the cover without removing?
Visually inspect the surface for cracks, especially around the kick starter axis, and a permanent oil fogging at the bottom of the node may also be a sign of a breach of integrity or tightness.
Will the lid from IZ Jupiter fit to Planet 5?
No, the generator covers have different seating, openings and interior dimensions, and you can't install an inappropriate cover without a major overhaul.
