How to Maintain Your Toyan Engine After a Period of Use
Similar to most RC engines, regular maintenance of your Toyan RC engine is essential to ensure smooth operation and extend its service life. Key maintenance practices include preventing the engine from overheating, using high-quality fuel, and replacing air filters regularly.
Recommended After-Run Oil: Zap PT31 PT-31 After Run Engine Oil (28ml)
This oil is ideal for cleaning the engine and preventing rust. Its protective effects can last for several months. It is particularly suitable for the metal push rod inside the engine casing. Apply the oil to the surface of the push rod before inserting it into the tube.
| Product | Volume | Key Benefits |
|---|---|---|
| Zap PT31 PT-31 After Run Engine Oil | 28ml | Cleans the engine, prevents rust, and provides long-lasting protection. |
Using After-Run Oil to Maintain Your Toyan RC Engine
Let’s take the Toyan 4-Stroke RC Engine as an example.
To reduce internal erosion, after running the engine, add 6-7 drops of after-run oil through the carburetor. Important: Do not use WD-40! Rotate the engine for 2-3 seconds without connecting the fire head and power. This allows the after-run oil to circulate inside the engine. Avoid adding the oil into the exhaust vent or the fire head hole.
After-run oil is cost-effective and provides excellent protection for your engine. Do not use unbranded engine oil or substitutes like WD-40 or gasoline engine oil. After-run oil contains ingredients that dissolve nitro components in the fuel and prevent rust on aluminum pistons and parts. If you use "vegetable oil," there is no need to add after-run oil.
| Step | Action |
|---|---|
| Add After-Run Oil | 6-7 drops through the carburetor. |
| Rotate Engine | 2-3 seconds without fire head and power. |
| Avoid | Adding oil into the exhaust vent or fire head hole. |
Other Maintenance Tips for Your Toyan RC Engine
Greasing the Rocker Camshaft
After the engine has run for 10-15 hours (approximately 5 liters of fuel), apply grease to the top rocker camshaft. The Toyan 4-stroke engine has an independent valve mechanism but no independent lubrication system. The internal piston connecting rod is lubricated by the combustion of the lubricating oil component in the fuel. However, the lubricating component cannot reach the top of the rocker camshaft, which may cause wear. Regularly check and add grease to prevent this.
| Maintenance Task | Frequency | Action |
|---|---|---|
| Grease Rocker Camshaft | Every 10-15 hours | Apply grease to the top rocker camshaft. |
Long-Term Use Inspection
If the engine has been used for 60-80 hours, contact your supplier or an experienced RC engine player. They can inspect the engine for proper operation and check for wear on the connecting rods and front and rear bearings. To avoid damage, seek assistance from a professional model shop and use specialized bearing-removal tools.
| Inspection | Action |
|---|---|
| Check Connecting Rods | Inspect for wear and tear. |
| Inspect Bearings | Check front and rear bearings for wear. |
Air Filter Replacement and Storage
When replacing the air filter, store your engine in a dry place. Proper maintenance, including cleaning and adding after-run oil, will keep your engine performing well.
| Storage Tip | Action |
|---|---|
| Store in a Dry Place | Ensure the engine is kept in a moisture-free environment. |
| Replace Air Filter | Regularly replace the air filter for optimal performance. |
