The Komatsu 930E-5 truck platform is still a relatively recent entrant to most mining fleets. But for the earlier adopters – especially those that have racked up significant hours over the past five years – the first wave of major component overhauls is now due. 

And that’s where the pressure starts. 

Across the board, maintenance teams are flagging the same issue: GDY106B wheel motors are expensive, increasingly hard to source, and difficult to replace. New spares are limited, and replacement cores are scarce – creating a major supply risk just as trucks reach their first scheduled rebuild cycle. 

That’s why we built the VALC 930E-5 | G707B. 

A Smarter Wheel Motor for a New Phase of Fleet Life 

Launched in August 2025, the VALC G707B Wheel Motor is a direct replacement for the Komatsu GDY106B – engineered to be fully compatible, rebuild-ready, and performance-enhanced for the next generation of 930E-5 operations. It’s based on our proven G707A platform, trusted by 930E-4 operators in some of the world’s most demanding haul environments. But with the G707B, we’ve taken the design even further – introducing a major upgrade to address one of the most serious failure modes observed in GDY106B-equipped trucks worldwide.

The Breakthrough: Our Heavy-Duty Low Speed Carrier, Standard

One of the improvements that sets the G707B apart is its inclusion of the VALC Heavy Duty Low Speed Carrier – a proprietary enhancement engineered to eliminate the internal bolt shear failures that have plagued a growing number of 930E-4 and 930E-5 motors. This isn’t theory. It’s a field-proven solution, backed by: 

• Finite Element Analysis (FEA) validation 
• Metallurgical and structural testing 
• 10,000+ operational hours across live sites 
• A design that simplifies inspection and dramatically reduces failure risk 

Key benefits: 

• 6-bolt external configuration for reduced stress and easier inspection 
• Lower localised stress concentrations = longer service life 
• Enhanced pin interface and simplified maintenance 
• Designed for higher loads – built with 360T trucks in mind 

What Else Makes the VALC G707B Different? 

While supply chain volatility affects every part of the mining value chain, truck OEM wheel motors can be a particularly vulnerable choke point. With limited core availability, high capital cost, and long lead times, many operators are left scrambling. The G707B provides a better option: 

• Plug-and-play GDY106B compatibility – no retrofit required
• Full rebuild and service exchange programs
• Thermal and mechanical upgrades derived from G707A learnings
• Heavy Duty Low Speed Carrier included as standard
• Global technical and after-sales support
• Lower total ownership cost – without compromising performance

Why Now? 

930E-5 fleets are reaching a pivotal moment. As fleets mature, the cost and availability of spares – especially wheel motors – become mission-critical. And with the GDY106B becoming increasingly difficult and expensive to source, waiting and hoping for a solution is no longer a viable strategy.
