WG9003071105 Double Oil Seal 10513012 (110g) 1051308 (83.5g)

WG9003071105 is a dedicated dual oil seal assembly for Sinotruk gearboxes, consisting of two commonly used oil seal specifications with standard weight and dimensional parameters. It is suitable for key sealing positions such as the gearbox output shaft and flange.

Adopting a composite rubber and metal skeleton reinforced design, it features high rigidity, stable shape retention, and outstanding compression and torsion resistance.

Manufactured in strict accordance with original factory dimensional tolerances, it fits tightly after installation and allows in-situ replacement without modification.

Applicable to various working conditions of heavy-duty trucks such as Howo, its double-layer protection effectively prevents oil seepage, dust ingress and water penetration. It reduces wear on bearings and gears, keeps the gearbox transmission system clean and well-lubricated, and ensures stable and long-term operation.

This dual oil seal set consists of two matched specifications: 10513012 and 1051308, weighing 110g and 83.5g respectively. It is integrally molded from special oil-resistant and temperature-resistant rubber material.

The rubber compound features dense texture and excellent flexibility, with great resistance to aging, wear, high and low temperatures, perfectly adapting to the long-term high-temperature and heavy-duty operating conditions of gearboxes.

The lip is precisely finely polished to fit closely against the shaft surface with superior sealing performance. The double sealing structure effectively prevents lubricating oil leakage and blocks dust, mud and water from entering the interior.

Its dimensions strictly comply with original assembly standards, offering good resilience and resistance to hardening and cracking. It maintains lasting and stable sealing performance after installation, greatly reducing oil leakage failures and extending the maintenance cycle of the gearbox.
