BONDERITE® L-GP 39SY201 (310 PENT), previously known as 39SY201, is a formulated gear marking compound specifically engineered to evaluate the alignment of matched gear sets in the automotive sector. This product comes in the form of a vibrant yellow paste that is simply applied to the mating surfaces of gear sets with a brush. Once applied, as the gears engage and rotate, the compound creates a distinct and visible pattern, effectively exposing any misalignment or inconsistencies on the gear surfaces. This visual representation not only aids in identifying areas that may cause gear howling but also pinpoints potential issues that could result in premature wear or significant part damage if not addressed. By using BONDERITE® L-GP 39SY201 (310 PENT), automotive professionals can ensure optimal gear performance and longevity, facilitating smoother operations and preventing costly repairs in the long run.
