Webb Severe Duty has announced that its Vortex drums will be offered as direct replacements for all its previous MAN transit axle part numbers. Webb Vortex drums are designed for lighter weight than standard grey iron drums while maintaining superior strength, with enhanced heat management characteristics important in transit operations. Vortex drums are designed to increase safety and performance, provide added durability and help decrease maintenance costs.
MAN transit axle brake drums can be ordered from Webb distributors as 74040B, which is the replacement for 64040B and 74089B to replace 64089B. The new 70000 series Vortex drums will supersede the previous part numbers for all MAN axle applications, including Superpak products.
