Q & A
What is the main focus of today's tech talk by Brian Perego?
-The main focus of today's tech talk is on wheel end products, specifically Guardian HP and Sentinel technology, and how they contribute to making roadways safer.
How long has Stemco been serving the industry with their seals?
-Stemco has been serving the industry with their seals for 70 years.
What does the number in the prefix of the product numbering system represent?
-The number in the prefix represents the type of vehicle component: a seven indicates a trailer, an eight indicates a steer, and a nine indicates a drive.
What is the purpose of the extra wear ring in the Guardian HP seal?
-The extra wear ring in the Guardian HP seal is designed to protect the axle, making it a preferred choice in trailer manufacturing and for those seeking extra protection on their spindle.
What is the proper method for removing the axle ring from the spindle shoulder?
-The proper method for removing the axle ring is to use a ball peen hammer to lightly flatten it out, ovaling it, which prevents damage to the spindle.
How often should the spindle be replaced if the measurement difference between the top and bottom is more than a certain amount?
-If the measurement difference is more than six to ten thousandths, it's time for a replacement of the spindle.
What is the 211 procedure for installing the hub onto the spindle?
-The 211 procedure involves initially seating the hub by torquing it to 200 foot-pounds, spinning the hub at least one full turn, re-torqueing, and repeating this process three times. Then, the hub is backed off one full turn without spinning, re-torquing to 100 foot-pounds, and repeating this process three times. Finally, the hub is backed off one more full turn and a face mark is used to indicate the final position.
Why is it important to avoid mixing lubricants when working on bearings?
-Mixing lubricants can lead to reduced performance and potential damage. It's best to have the same lubricant throughout the whole procedure to ensure proper functioning and longevity of the bearings.
What are the benefits of using the Sentinel hubcap compared to standard hubcaps?
-The Sentinel hubcap has a duckbill valve for pressure release and a Gore-Tex membrane that makes it fully waterproof and dustproof, protecting the wheel end from water infiltration and contamination, which can lead to premature failure.
How does the Sentinel technology work to prevent water infiltration in the hub cavity?
-The Sentinel technology uses a Gore-Tex membrane in the hubcap, which is fully waterproof and dustproof. It allows pressure to be released when needed but prevents water from entering the hub cavity, even under high vacuum pressure.
What is the final step in the installation process of the wheel end assembly?
-The final step is to install the hubcap with a new gasket, ensuring it is properly sealed by tightening it in a star pattern to prevent leaks. The assembly is then filled with oil until it reaches the appropriate level on the hubcap.
