BRM Announces Cylinder Honing Tools for Universal Joints; Flexible Hones Improve Surface Finish of U-Joint Bores, Other Auto Parts

Share Article

Brush Research Manufacturing (BRM), American-owned maker of engine hones and automotive brushes, announces cylinder honing tools for surface finishing U-joint bores. Professional automotive technicians and do-it-yourself (DIY) mechanics alike use Flex-Hone® tools to impart an ideal surface finish to auto parts such as universal joints, important drivetrain components in cars and trucks.

Brush Research Manufacturing (BRM), maker of cylinder hones and automotive brushes, is announcing Flex-Hone® tools for surface finishing the bores of universal joints. Flexible hones are used in a range of automotive applications, including engine block honing, brake rotor finishing, cylinder wall deglazing, and cross-hole deburring.

Automotive Repairs and U-Joint Replacement

Universal joints help to transfer power from a car or truck’s engine to its wheels. These drivetrain components have four “legs,” each of which ends in a needle-bearing cup. Two cups connect to the driveshaft. The other two cups attach with yokes to the transmission or rear differential, depending on the vehicle.

Although routine automotive maintenance can extend component life, universal couplings can wear and fail. Some vehicle owners prefer to have a professional auto technician replace bad U-joints. Other car and truck owners choose to replace universal joints themselves, often as part of a larger DIY project that includes replacing related auto parts such ball joints and hubs.

Bad U-Joints and Good Automotive Tools

Such was the case with a mechanic and member of Turbo Diesel Register (TDR), an on-line automotive forum where users ask questions, get answers, and describe their automotive repairs. For ENafzinger, the owner of a Dodge RAM 3500 truck, the hardest part of a U-joint replacement project was loosening the old universal joints.    

Removing the U-joints deformed the yokes, but the truck owner used handheld tools to restore their proper shape. The DIY mechanic then used what he called a “cylinder dingle ball hone” to “clean up the U-joint bores.” The cylinder hone that he used, the Flex-Hone® from Brush Research Manufacturing (BRM), is sometimes called a ball hone or dingleberry hone because of its distinctive abrasive globules.

Flexible Honing Tools

Flexible hones are known for more than just their abrasive “balls” or “dingleberries,” however. Self-centering, self-aligning to the bore, and self-compensating for wear, BRM’s cylinder honing tools mount in handheld electric drills and are easy-to-use. Rigid, elaborate setups aren’t required, and the Flex-Hone® tool imparts a plateau finish that optimizes lubrication.

Flex-Hone® tools are always specified in an oversized condition (larger than the bore) and are available for any size or type of cylinder. Standard BRM cylinder hones range in diameter from 4mm to 36”, and come in 8 abrasive types and 11 different grit selections. The Flex-Hone® Resource Guide, a free downloadable technical book from Brush Research, provides more information on tool selection.
