Product Features

• Structure: A multi-lip, composite seal made of oil-resistant, high-temperature nitrile rubber, with a metal reinforcement framework and a spring-loaded lip for consistent sealing pressure.

• Performance: The rubber lip maintains a tight seal against the crankshaft, preventing oil leakage even under high rotational speeds and temperature fluctuations. The ribbed outer casing ensures a secure press-fit installation in the engine block.

Core Function

• Seals the rear end of the crankshaft to prevent engine oil from leaking into the flywheel housing.

• Blocks dust, water, and other contaminants from entering the engine’s internal components, protecting the crankshaft journal and flywheel from wear.

• Maintains proper oil pressure within the engine, ensuring reliable lubrication of critical components.

Crankshaft Rear Oil Seal 201V01510-0283 SINOTRUK – OEM Quality, Factory Direct Price

When your SINOTRUK engine demands flawless sealing performance at the crankshaft-to-flywheel housing junction, the Crankshaft Rear Oil Seal 201V01510-0283 stands as your most reliable guardian against oil leakage. Engineered to OEM specifications, this seal works tirelessly to keep engine oil exactly where it belongs — inside the crankcase — so your fleet stays on the road and your maintenance costs stay low.

Key Functions & Benefits of Crankshaft Rear Oil Seal 201V01510-0283

This SINOTRUK crankshaft rear oil seal is purpose-built to prevent engine oil from escaping through the gap between the crankshaft rear end and the flywheel housing. Without a properly functioning rear oil seal, oil migrates onto the clutch or flywheel surface, causing slippage, contamination, and costly downtime.

• Precision Leak Prevention – Creates a dynamic seal at the crankshaft rear journal, blocking oil from reaching the flywheel housing cavity even under high crankcase pressure.
• High-Temperature Resistance – Manufactured from fluoroelastomer (FKM/Viton) compound that withstands continuous operating temperatures up to 200°C without hardening or cracking.
• Extended Service Life – The PTFE sealing lip minimizes friction against the crankshaft surface, reducing wear and delivering a service life exceeding 300,000 km under normal operating conditions.
• OEM Dimensional Accuracy – Matches original SINOTRUK specifications to ensure drop-in fitment with zero modification required.
• Dust & Contaminant Exclusion – Integrated dust lip prevents external particles from entering the seal interface, protecting both the seal and the crankshaft journal.

Application: Compatible SINOTRUK Vehicle Models

The Crankshaft Rear Oil Seal 201V01510-0283 is designed for SINOTRUK vehicles equipped with the MC11/MC13 series engines (MAN technology platform). It fits the following models:

• SINOTRUK SITRAK C7H – 6×4 Tractor Head, 440HP/480HP configurations
• SINOTRUK HOWO T7H – 6×4 Tractor & Dump Truck variants
• SINOTRUK HOWO T5G – 4×2 and 6×4 Cargo & Mixer Truck
• SINOTRUK HOWO A7 – Select models with MC engine platform
• SINOTRUK SITRAK C5H – Medium-duty applications with MC11 engine

This seal specifically addresses the critical sealing point where the crankshaft exits the engine block and meets the flywheel housing assembly. When this seal fails, operators typically notice oil spots beneath the bell housing, a burning oil smell, or clutch slippage caused by oil contamination.

Frequently Asked Questions – Crankshaft Rear Oil Seal 201V01510-0283

What are the symptoms of a failing crankshaft rear oil seal?

A worn crankshaft rear oil seal typically announces itself through oil dripping from the bell housing area, visible oil residue on the flywheel or clutch disc, and in severe cases, clutch slippage due to oil contamination. If you notice a persistent oil puddle forming beneath the transmission-to-engine junction, this seal is the most likely culprit.

Is part number 201V01510-0283 interchangeable with other SINOTRUK seal numbers?

This part number is specific to the MC11/MC13 engine platform used in SITRAK C7H, HOWO T7H, and HOWO T5G models. It is not interchangeable with the older WD615 engine rear oil seal (part number VG1500010047). Always verify your engine model before ordering to ensure correct fitment.

What material is this crankshaft rear oil seal made from, and why does it matter?

The seal uses FKM (fluoroelastomer) with a PTFE sealing lip. FKM resists degradation from engine oil, high temperatures, and chemical additives found in modern synthetic lubricants. The PTFE lip reduces rotational friction by up to 50% compared to standard nitrile (NBR) seals, which directly translates to longer seal life and less crankshaft journal wear.

How difficult is it to replace the crankshaft rear oil seal?

Replacement requires removing the flywheel and flywheel housing to access the seal seat. For experienced technicians with proper tooling, the job typically takes 3–5 hours. The seal itself is a press-fit component — a seal driver tool matching the 150 mm outer diameter ensures even installation without damage to the sealing lip.

What is the expected lifespan of this oil seal under normal conditions?

Under standard operating conditions (proper oil level, no excessive crankcase pressure, and normal engine temperatures), this seal is engineered to last 300,000+ km or approximately 5,000 engine hours. Premature failure is usually caused by a blocked crankcase ventilation system that creates excessive internal pressure.

Can I order a sample before committing to a bulk purchase?

Absolutely. We encourage buyers to evaluate quality firsthand. Sample orders are available with standard lead times, and sample costs can be credited toward your first bulk order. We also welcome customers to visit our facility in Jinan, China for on-site inspection.
