The Flex-Hone® is a flexible, resilient honing tool that breaks the glaze on cylinder walls and imparts an ideal surface finish.
Los Angeles, CA (PRWEB) September 11, 2013
Brush Research Manufacturing (BRM), maker of flexible hones and a full line of industrial brushes, is announcing cylinder honing tools for overhauling diesel engines. The Flex-Hone® is a flexible, resilient honing tool that breaks the glaze on cylinder walls. Left unbroken, an overly smooth surface finish can impede lubrication and increase friction.
After engine cylinders are manufactured, their walls or liners are surface-finished to impart a series of oil-retaining grooves or valleys that promote oil retention. During engine break-in, the reciprocating movement of the pistons removes peaks and leaves a uniform series of ridges. Over time, however, the up-and-down movement of the pistons creates a polish or glaze on the cylinder walls.
Diesel Engines and Glaze Breaker Hones
In an article entitled Rebuilding International’s 7.3L IDI Engine Heads and Crank, Diesel Power magazine explained how an engine builder used the BRM Flex-Hone® to break this glaze and improve the surface finish of cylinder walls. Made by International Harvester, the eight-cylinder diesel powerplant was used in Ford F-Series pickups, Ford E-Series vans, school buses, and commercial vehicles.
As the article’s author explained, only one of the eight cylinders had “some surface rust” with the other seven free of “major scratches or blemishes”. While a machine shop cleaned the crankshaft, resurfaced the heads, and completed a valve job, the do-it-yourself (DIY) mechanic used a flexible honing tool from BRM in a handheld electric drill.
How to Use Flexible Honing Tools
With the flexible hone lubricated generously and spinning at the recommended RPMs, the diesel mechanic stroked the cylinder according to the recommendations in the Flex-Hone® Resource Guide. As BRM’s free, downloadable technical book explains, ball hones are low RPM tools that are self-aligning to the bore, self-centering, and self-compensating for wear.
When cylinder honing is complete, Flex-Hone® customers such as Caterpillar use warm soapy water for cleanup. In addition to high-quality brush tools, BRM supplies high-quality cylinder wash brushes made of 6-12 Nylon in diameters ranging from 3.5-in to 6.5-in. After cleaning an engine block, remember to lubricate metal surfaces properly.
