Products Description

This is the front crankshaft oil seal with part number 61500010037, specially made for HOWO heavy trucks, and it's an essential engine spare part. It stops engine oil leaking out from the front crankshaft close to the pulley, so the engine can keep steady internal oil pressure while running. We use heat-resistant and wear-proof fluororubber for production. Even with heavy loads, high engine temperatures and long-hour continuous driving, it can stay tightly sealed without failing. It's manufactured strictly following OEM size standards, tough to wear out and simple to mount. It works as a direct replacement for HOWO, Shacman, AUMAN and other heavy trucks fitted with WEICHAI WD615 or WP10 engines.

Applicable

① Applicable Vehicles: Fits heavy-duty trucks and construction machinery matched with WEICHAI WD615, WP10 engines, including HOWO, Shaanxi Delong, Foton AUMAN, Steyr series heavy trucks, loaders and engineering vehicles.

② Adaptable System: Perfectly matches original WEICHAI engine crankshaft front end assembly. It can be directly installed without cutting, polishing or structural modification, and fits original crankshaft, gear chamber and pulley assembly accurately.

③ OE Reference Number: 61500010037

④ Interchangeability: Produced strictly in accordance with OEM original size 95×115×12mm, consistent with original inner and outer diameter, thickness and lip structure. Direct replacement for original oil seals, fast disassembly and assembly, effectively reducing maintenance time and labor expense.

⑤ Value-added Service: We can confirm product compatibility according to your truck brand, engine model and VIN code. We also supply professional guidance for installation, oil leakage inspection and daily engine maintenance to avoid early seal aging and oil seepage caused by incorrect fitting.

Materials & Craftsmanship

Core Materials

This crankshaft front oil seal is mainly made of high-performance fluororubber, fitted with a sturdy metal inner frame to hold its shape well. It can stand high engine heat, erosion from motor oil, as well as dirt and mud splashing up during driving. Its flexible sealing lip stays tightly pressed against the spinning crankshaft even after long hours of high-speed running, so it won't turn stiff, warp or leak oil. An inner tension spring keeps steady pressure all the time, stopping oil seepage caused by engine vibration or heat expansion. Whether the truck makes frequent stops and starts or runs long-distance heavy loads, it keeps reliable sealing inside the hot engine bay.

Surface Treatment

The sealing lip is precisely polished to reduce friction loss with crankshaft and avoid abnormal wear. The outer rubber surface is treated with anti-aging and anti-oil coating, effectively delaying rubber cracking and embrittlement. The metal skeleton undergoes rust-proof treatment to prevent oxidation and deformation after long-term contact with oil and muddy water. The whole seal maintains stable elasticity and tightness in dusty, high-temperature and vibrating engine working environment.

Production Craftsmanship

We adopt mature rubber vulcanization and skeleton integrated molding technology to ensure the oil seal has uniform hardness and stable elasticity. All key dimensions including inner diameter, outer diameter and thickness are precisely controlled during production to achieve seamless matching with original crankshaft installation position. Every finished oil seal passes strict quality inspection: high-temperature aging test, oil immersion corrosion test and rotary sealing leakage test. Each batch is fully inspected to eliminate defective products. We produce fully following OEM original design standards, so our oil seals reach the same sealing performance and service life as factory original parts.

FAQ

Q: What advantages does this oil seal have over ordinary aftermarket seals?

A: It is made of high-temperature resistant fluororubber with built-in reinforced metal skeleton and constant force tension spring. Compared with ordinary nitrile rubber oil seals, it has stronger anti-aging, oil-resistant and high-temperature resistant performance, not easy to crack or leak oil after long-term operation. Standard OEM size ensures close fit with crankshaft to eliminate seepage risk.

Q: Is the quality reliable? How long is its service life?

A: All products are manufactured according to OEM standards and pass independent sealing and aging tests. With excellent wear and corrosion resistance, it can normally work for 1–2 years under standard vehicle maintenance, suitable for long-distance freight and daily heavy-duty transport vehicles.

Q: What benefits will you get after replacing this oil seal?

A: It thoroughly solves engine oil leakage at crankshaft front end, keeps engine oil volume stable, avoids oil shortage damage to engine components. It reduces oil consumption and chassis pollution, protects crankshaft and pulley from oil corrosion, and lowers follow-up engine maintenance cost. Meanwhile, it keeps the engine compartment clean and improves vehicle operation stability.
