Description:Couplers usually are secured to the nose base with a hammerless retainer that pulls the coupler tight. In some cases, coupler pocket has a dual load bearing surfaces to minimize nose stress and wear. Moreover Coupler pocket evenly distributes load on nose base to reduce stress. in case of Extended life couplers, the maintenance time is decreased by increasing the wear material thereby reducing the number of times for change outs. Also. material added to top of coupler to create a uniform profile maintains penetrations and material flow. Added material around retention system also decreases the wear on renettion system.
