New Pin Design for 10x4, 14x6, and 18x8 H & HM Brakes
 

The base pin, shoe pin, and arm pin designs for 10x4, 14x6, and 18x8 Type H and HM brake assemblies have been improved. The following brake assemblies and pin kit numbers have been affected:   Size Type Brake No. Pin Kit No. Note 10x4 10x4 14x6 14x6 18x8 18x8 H HM H HM H HM J2926 J34780 J2929 J34735 J2932 J40065   J105197, J73925, J73926   J105197, J73925, J73926   J105198, J73927, J73928, J73929   J105198, J73927, J73928, J73929   J105199, J73928, J73929, J73930   J105199, J73928, J73929, J73930 (1)   (2)         (1) Also applies to J53958 and J107077 (10" H brakes with air release/spring set actuator).   (2) Also applies to J53957 (14" H brakes with air release/spring set actuator).   When installing these pins on existing brakes (seven total per brake assembly), it will be necessary to enlarge the present holes to allow the new pins to mount in the appropriate base, top arm, shoe, and shoe arms. Pins are provided with snap rings.   New Pin Construction (Typical)   Brake Size Pin Dia. 10x4 14x6 18x8 3/4" *1" 1" & 1-1/4"  *1-1/4" for base pins     1" all other pins   Please note items 5 and 8 on the illustration below as an example of pin locations.     This new pin design has been initiated in June 1992. New brakes will utilize this new design. The brake base, top arm, shoe, and shoe arms will also be manufactured for this pin design. If a customer purchases a replacement brake base, top arm, shoe, or shoe arm to repair an existing brake assembly, he should also purchase a new pin kit. At that time, the brake assembly can be updated to the new pin design.
