2HL290 Mission Complete Transmission Overhaul Seal Kit High-Temp Elastomers for Heavy Machinery Gearbox

When overhauling a heavy-duty power shift transmission or gearbox, missing a single internal seal or using sub-standard rubber can result in costly transmission teardowns, gear slipping, and internal fluid leaks.

The 2HL290 Mission Seal Kit provides a complete, all-in-one rebuild package. Every elastomeric component in this kit is forged from 100% Taiwan-imported GEMORS premium raw materials, engineered specifically to endure continuous rotational friction, high gear oil temperatures (up to +150°C), and extreme hydraulic shifting pressures.

As illustrated in our product photographs, this comprehensive overhaul set includes precisely engineered components specifically matched for 2HL290 transmission applications:

• 3 x High-Performance Rotary Shaft Oil Seals (Brown FKM/Viton Cased Lip Seals):

  • Function: Installed on rotating input and output transmission shafts.

  • Material Advantage: Made of high-grade brown GEMORS FKM (Viton) with metal reinforcement and tension springs. Exceptional resistance to extreme gear oil heat and high-speed rotary abrasion.

• 4 x Heavy-Duty Dynamic Sealing Rings (Large Black Outer Rings):

  • Function: Provides critical dynamic sealing across rotating clutch packs and gear assemblies.

  • Material Advantage: Low-friction, wear-resistant compound engineered to prevent internal oil bypass and maintain firm clutch engagement.

• 4 x Large Static Housing O-Rings (Medium-to-Large Black Rings):

  • Function: Seals transmission case housings, pump covers, and intermediate mating flanges.

  • Material Advantage: High-tensile Taiwan GEMORS NBR/FKM compound that will not harden, shrink, or degrade under continuous thermal cycling.

• 1 x Complete Set of Valve & Hydraulic O-Rings (Multi-Size Small Black O-Rings & Back-ups):

  • Function: Seals shifting control valves, pressure regulators, and internal hydraulic routing channels.

  • Material Advantage: Exact structural tolerances ensure tight pressure retention for responsive, jerk-free gear shifting.

• Q: Are these seals suitable for high-temperature transmission environments?

  • A: Yes! Because we use 100% Taiwan-imported GEMORS FKM and premium compounds, these seals easily tolerate continuous elevated gear oil temperatures that would cause standard rubber to melt or crack.

• Q: How do you ensure the dimensions match my transmission assembly?

  • A: Precision is our priority. Our warehouse team performs strict physical measurements and quality verification on every kit before it leaves our facility.

• Q: What global payment and shipping options do you support?

  • A: We support fast, low-fee payment channels including T/T, WorldFirst,  and WeChat Pay. Orders are securely packed in protective anti-static bags and shipped globally via trusted air or sea express.
