Mobil Dynagear™ 4000 open gear lubricant enhances protection

Mining equipment lubricant

Caterpillar BI495 Shovel – Hoist Mining Company

Quebec, Canada


A Canadian mining company operating a BI495 shovel received a service notice identifying a change to Caterpillar's specifications for the open gear lubricant on that shovel model's hoist. Company personnel approached ExxonMobil to identify a lubricant for the shovel hoist that met the new system specifications.


ExxonMobil recommended Mobil Dynagear™ 4000 open gear lubricant along with a performance study to evaluate the product. Mobil Dynagear 4000 lubricant was formulated to meet the Caterpillar™ SD4713 specification and provide outstanding protection of heavily loaded gears while using solvent free technology to help reduce run-off during application.


Maintenance personnel were thoroughly impressed by the performance capabilities of Mobil Dynagear 4000 open gear lubricant. Results of the performance study indicated the new hoist lubricant performed well, maintained its characteristics while in service and helped to protect the gears. The company estimates the change will result in improved production reliability and reduced equipment maintenance, costs that can be significant for a shovel. Confident in the enhanced protection, the company has since transitioned three of its shovels to Mobil Dynagear 4000.

The product performance of Mobil Dynagear 4000, alongside the application expertise provided by local ExxonMobil engineering support, is helping to improve customer productivity potential.
