Takeaways

• 🔧 The video explains how to install a cylinder block (blok seher) on a Revo Absolute motorbike.
• 🛠️ The cylinder block issue is caused by excessive oil consumption, which leads to oil burning and engine smoke.
• 🔄 The block has been overhauled and resized (korter) to address the problem.
• ⚙️ The piston rings need to be properly installed, as shown in a previous video.
• 🔩 The tutorial covers the process of attaching the piston and cylinder block, including the use of oil for lubrication.
• 🔧 Attention is given to installing and aligning the camshaft (gigi sentrik) to ensure correct engine timing.
• 🔑 Valve clearance adjustments are made, with specific gaps for intake and exhaust valves (0.05 mm and 0.08/0.09 mm respectively).
• 🚗 The installation of a new timing chain (rantai keteng) is checked, ensuring it's properly tensioned.
• 🧰 The tutorial also highlights the importance of sealing components with gasket glue to prevent oil leaks.
• 🔑 After the installation, the video checks engine compression and ensures the engine starts properly with smoother sound from the timing chain.

Q & A

What is the main topic of the video?

The video provides a tutorial on how to install a cylinder block and piston, particularly for a Revo Absolute motorcycle.

What issue does the video aim to address?

The video addresses the issue of excessive oil consumption and smoke from the motorcycle, which is likely due to piston block problems.

What modification has been made to the cylinder block before installation?

The cylinder block has been rebored to an oversized 50 mm to address the problem of excessive smoke and oil consumption.

What precautions are mentioned for piston ring installation?

The video emphasizes the importance of correctly positioning the piston rings before installing the cylinder block, ensuring they are properly aligned.

What role does oil play in the assembly process?

Oil is applied to components like the piston and cylinder to ensure smooth installation and to prevent damage during initial engine startup.

Why is it important to align the marks on the timing system?

The marks on the timing system must be aligned correctly to ensure the engine is at its proper 'top dead center' (TDC) position, which is crucial for the correct timing of the engine's valve operation.

What tool is recommended for tightening bolts during assembly?

The video suggests using a torque wrench to ensure the bolts are tightened evenly and to the correct specification, ensuring a proper seal and preventing damage.

What is the recommended valve clearance setting?

The recommended valve clearance is 0.05 mm for the intake valve and 0.08-0.09 mm for the exhaust valve.

Why is it important to check the cam chain tension?

It is important to check the cam chain tension to ensure it is neither too loose nor too tight, which could affect engine performance or cause damage.

What final steps are taken after reassembling the engine?

After reassembling the engine, the video recommends replacing the oil, checking the compression by hand, and starting the engine to check for smooth operation and ensuring the engine runs without excessive noise.
