Product Features

• Structure: Made of high-strength alloy steel, heat-treated for maximum tensile strength. It features a flange head design and a precision-machined threaded section for a secure, torque-controlled fit.

• Performance: The alloy steel construction withstands the extreme rotational forces and vibration of the engine, maintaining a tight, reliable connection between the flywheel and crankshaft.

• Design: Engineered to meet OEM torque specifications, with a flange head that distributes clamping pressure evenly to prevent damage to the flywheel or crankshaft mating surfaces.

Core Function

• Secures the flywheel to the crankshaft, ensuring precise alignment and transferring rotational power from the engine to the transmission.

• Maintains the critical balance of the crankshaft-flywheel assembly, preventing vibration and premature wear of engine and transmission components.

• Resists loosening under high-load conditions, ensuring the flywheel remains safely attached during vehicle operation.

Frequently Asked Questions – Flywheel Bolt 200V90020-0419

What is the correct installation torque for Flywheel Bolt 200V90020-0419?

The installation torque must follow the SINOTRUK engine workshop manual for the specific engine model (MC11, MC13, D12, or WD615). Typically, flywheel bolts of this grade require a multi-step torque-plus-angle tightening procedure to achieve proper preload. We recommend always using a calibrated torque wrench and following the OEM torque sequence.

Can Flywheel Bolt 200V90020-0419 be reused after removal?

SINOTRUK service guidelines generally classify flywheel bolts as torque-to-yield (TTY) fasteners. Once stretched to their yield point during installation, they should be replaced with new bolts during every flywheel or clutch service to ensure safe clamping force. We strongly advise against reuse.

How does this flywheel bolt differ from aftermarket alternatives?

Our 200V90020-0419 flywheel bolt matches OEM metallurgical composition, heat treatment profile, and dimensional tolerances. Many generic aftermarket bolts use lower-grade steel or skip precision heat treatment, which can lead to premature fatigue failure, flywheel loosening, or catastrophic engine damage under load.

What quantity should I order per vehicle?

SINOTRUK engines typically use 8 to 12 flywheel bolts per engine depending on the model. For fleet maintenance stock, we recommend ordering in multiples of the full set quantity plus a safety margin for inspection rejects or damaged threads during removal.

Is this flywheel bolt compatible with Weichai-powered SINOTRUK trucks?

Part number 200V90020-0419 is specific to SINOTRUK’s MAN-technology engine series (MC11/MC13). For Weichai WP-series engines used in some SINOTRUK models, a different flywheel bolt part number applies. Contact us with your engine nameplate data and we will confirm the correct part for your application.
