The types are differ- entiated by the pinion stem diameter....1-3/8", 1-3/4", 1-7/8".? The choice of axle pinion assembly was determined based on the application. 1-3/8" small stem pinion... (aka. '741')... Carrier casting numbers:? 1820657 (1957-1964), 2070741 (1964-1972). This assembly was typically used in low weight/low horsepower applications through low weight/medium horsepower and high weight/low horsepower applications. Pinion depth and bearing preload is set with shims.? Differential bearing setting (ie. backlash ) is set with threaded adjusters. 1-3/4" large stem pinion... (aka. '742')... Carrier casting numbers:? 1634985 (1957-1964), 2070742 (~1961-1969). This assembly was replaced by a phase-in of the 1-7/8" pinion starting in the 1969 model year.? 1970 RW (Plymouth and Dodge mid-size) were the last models to use the 1-3/4" which appeared in a 2881489 case. This assembly was typically used in high weight/medium horsepower applications through high weight/high horsepower applications. Pinion depth and bearing preload is set with shims.? Differential bearing setting (ie. backlash ) is set with threaded adjusters. 1-7/8" tapered stem pinion... (aka. '489')... Carrier casting numbers:? 2881488, 2881489 (1969-1974). This assembly was introduced in 1969 and was phased-in to relace the 1-3/4" unit through 1970.? Note:? the 1-3/4" pinion also appeared in some '489' carriers during this period.? By 1973, the '489' was the only unit available in passenger car applications. This assembly was typically used in high weight/medium horsepower applications through high weight/high horsepower applications. Pinion depth is set with shims, preload is set with a crush sleeve.? Differential bearing setting (ie. backlash ) is set with threaded adjusters. -- [Non-text portions of this message have been removed] =========================================================== Need to find the right school to fit your needs CollegeInformation.info has already found it.
