Technical Specification and Compatibility

Made from materials resistant to high temperatures and oil, it guarantees maximum service life.

Service Recommendation: Ensure Maximum Lifespan

Replacing the seal is a perfect opportunity to check the condition and level of the axle oil. If it is old or contaminated, replace it with new, high-quality HYPTRON oil, which will provide optimal lubrication and protect the entire mechanism.

Part's Role in the Machine and Failure Diagnostics

The pinion shaft seal is a critical component protecting the differential. Its failure leads to oil leaks, which can result in the seizure of bearings and gears due to a lack of lubrication.

  • › Visible oil leaks from the front of the axle, where the propshaft connects.
  • › Oil on the propshaft or under the machine near the axle.
  • › Low oil level in the axle with no other visible cause.
  • › Noisy axle operation, "whining" or "humming" (as a result of running with a low oil level).

Peace of Mind Guarantee: Why Choose Our Offer?

A leaking seal is a risk of seizing the entire axle.

The cost of a new seal is negligible compared to a differential overhaul. Don't take the risk – order a new, OEM-quality CORTECO seal and ensure your axle has 100% sealing and protection.

🔧 Expert's Guide: Key Installation Tips

  1. Inspect the shaft surface: Before installation, carefully check the pinion shaft surface for scratches or a groove. A damaged shaft will immediately destroy the new seal.
  2. Clean the housing bore: Thoroughly clean the bore in the axle housing of old sealant and dirt.
  3. Use a press or driver: Always use a press or a special sleeve with the same outer diameter as the seal to drive it in evenly and without damage.
  4. Lubricate the seal lips: Before installation, lubricate the inner lip of the seal with clean gear oil to avoid damage during the first rotation of the shaft.

Frequently Asked Questions (FAQ)

1. I have a leak from my axle. Is it definitely this seal?

A leak from the front of the axle at the propshaft is 99% of the time caused by the wear of this specific seal. Other possible causes are worn pinion bearings (which cause the shaft to wobble and destroy the seal) or a cracked axle housing.

2. What is the difference between a CORTECO product and cheaper replacements?

CORTECO is a world leader and an original equipment (OEM) supplier for many machine manufacturers. Their products are characterized by the highest quality rubber compounds and precision manufacturing, which guarantees a perfect fit and the longest possible service life, especially in harsh working conditions.

3. My old seal has worn a groove in the shaft. Can I install a new one?

Installing a new seal on a shaft with a worn groove is risky, as the new sealing lip will sit in the same spot and will quickly start to leak oil. In such a situation, it is recommended to replace the shaft or use a special repair sleeve.
