HEPI Enhancements

FOCUS ON INNOVATION
The HEPI product line has a consistent record of creating proprietary processes and application-specific components that improve service life and machine availability. Some of H-E Parts innovations include:

• Planetary and brake redesigns
• Underground drive axle design and manufacture
• Gearing, differential, final drive, and other major component design and re-manufacture
• Mechanical drive wheel group redesign and manufacturing
• HEPI oil sample plugs
• HEPI brake wear gauges
• HEPI collated pins
• Electric drive wheel group redesign and manufacturing
• Suspensions systems

PROPRIETARY HEPI TECHNOLOGY
In order to achieve substantial improvements and offer distinct value to our customers, our dedicated team utilize proprietary HEPI technologies such as;

The HEPI Control Fit wheel bearing assembly, which includes:

• Flexible spacer
• Hardened spacer
• Proprietary bearing design and specifications as well as our proprietary bearing fit and preload adjustment

H-E Parts Mining divisions also offer proprietary HEPI contamination control innovations which include:

• Isolation seal
• Contamination guards and contamination control attributes

Other offerings include:

• Engineered gear design and manufacture

INNOVATIVE BRAKE MONITORING
The HEPI brake wear gauge (BWG) is used to measure brake wear by informing the user as to how much of the brake life remains. The HEPI BWG is installed during a brake rebuild and stays in the wheel group to make testing convenient and safe.

One direct measurement is all that is required to determine brake pack wear. Brake bleeding, which is considered an arduous and lengthy task, is no longer required following measurements as the brake wear gauge doesn’t need to be removed from the brake group.

Additional benefits to the HEPI BWG are:

• The elimination of oil spills that can lead to slips, burns or environmental contamination
• Improve brake life monitoring and change out planning
• Improved accuracy and repeatability of brake wear measurements allow maintenance plans to be made with confidence.

DESIGN BENEFITS
At H-E Parts, we have developed the HEPI Colleted Pin to eliminate the need for the lancing or pressing of seized pins traditionally used on haul trucks. Conventional pins used in these locations are notoriously difficult to remove, wasting time, money and causing damage to housings.

Due to the innovative design of our HEPI Colleted Pin the need for lancing and boring is greatly reduced. This solution reduces costs and improves safety associated with the lengthy and arduous task of replacing regular OEM pins. HEPI Colleted Pins can be used for rear suspension, control rod and A-frame hitch pin assemblies.

INNOVATIVE OIL PLUGS
The HEPI oil sample plug (BEST Plug) is a small and easy-to-install component for wheel groups and differentials which offers customers a reliable, safe and convenient option when it comes to checking for contamination. When checking the magnetic plug condition for wheel groups, it reduces the need to drive the truck back and forth during servicing. For differentials, it reduces the need to use additional equipment such as pumps and hoses, and the ability to control the drain rate.

In addition to the HEPI BEST plug assembly, the HEPI oil sampling plug is offered for customers with a preference for fast, simple and easy oil sampling in their wheel groups. The HEPI oil sampling plug features an easy-to-use valve that allows the magnetic plug and oil sampling tube to be inserted and removed without allowing oil out or contaminants in. Much like the HEPI BEST plug, correct use ensures that oil spills and scalding risks are eliminated.
