Let's take a closer look at why this flywheel deserves your attention.
Features and Benefits
Flywheel 612630020051 is not just a metal disk. It performs several critical tasks at once, ensuring smooth and predictable operation of the power unit. First of all, it accumulates kinetic energy and smoothes out uneven rotation of the crankshaft. In addition, the flywheel ring gear interacts with the starter, ensuring reliable engine starting even in cold weather.
- Precise balancing:Each flywheel is dynamically balanced to reduce vibration and extend crankshaft life.
- Wear-resistant ring gear:The crown is made of hardened steel, so it withstands repeated starts and resists chipping of teeth.
- Smooth friction surface:the working plane is machined with high precision, which ensures reliable grip and minimal slippage.
- Forward Compatibility:The part fully corresponds to the original mounting dimensions of the Weichai WP12 engine, so the installation takes place without modifications.
- Factory price:Since Mettlead works directly with production, you get a favorable price without intermediary markups.
Application and Compatibility
Before placing an order, it is important to ensure that the correct part is selected. Flywheel 612630020051 is designed specifically for heavy equipment, so it copes well with high loads. Below we have compiled key information about compatibility and typical replacement scenarios.

When replacement is required
Over time, even the most durable part wears out, and then timely replacement helps avoid costly repairs. Pay attention to the flywheel in the following cases:
- Damage or breakage of the teeth of the flywheel ring gear, causing the starter to rotate with a characteristic grinding noise.
- Wear of the friction surface, which leads to clutch slipping.
- The appearance of cracks or deformation of the disk due to overheating or shock loads.

Client History
One of our partners, a wholesale distributor of auto parts from Kazakhstan, faced massive requests regarding the failure of flywheels on trucks with a Weichai WP12 engine. Their previous supplier regularly missed deadlines, and the ring gear of some parts quickly wore out. After switching toflywheel 612630020051From Mettlead the situation has noticeably changed for the better.
We promptly shipped a trial batch, and the client personally assessed the balancing accuracy and quality of the friction surface. As a result, the number of warranty returns has decreased, and repeat orders have begun to arrive monthly. Today, this partner purchases flywheel 612630020051 regularly, because he is confident in stable quality and predictable delivery times. This story clearly shows that choosing the right supplier directly affects the reputation of your business.
Frequently Asked Questions (FAQ)
Will flywheel 612630020051 fit Weichai WP12 engine?
Yes, this part is designed specifically for the Weichai WP12 engine and SINOTRUK HOWO equipment. However, we always recommend checking the part number before ordering to ensure there are no errors.
How do you know when it's time to change the flywheel?
Look for warning signs such as a grinding noise when the starter cranks, clutch slippage, or vibration. Most often, the cause is torn teeth of the ring, wear of the friction surface or cracks on the disk. If you notice at least one of the symptoms, it is better to replace it in advance.
What material is flywheel 612630020051 made of?
The flywheel housing is made of high-strength cast iron, and the ring gear is made of hardened steel. Thanks to this combination, the part can withstand high loads and resist tooth wear.
Can a new ring gear be installed separately?
In some cases, the crown is actually changed separately. However, if the friction surface is also damaged, we recommend replacing the entire flywheel to ensure reliable operation of the unit.
What is the delivery time and minimum order?
Lead times and minimum quantities depend on volume and logistics. Write to us, and our manager will quickly prepare an individual offer for you with the current price and deadlines.
