Topic: New Design Piloted Input Adjuster Released for D170 and D190 Models
Affected Models: All D170, D190, D590 Carrier Assemblies
As of August 1, 2006 all Dana D170, D190 and D590 forward carrier assemblies will be manufactured with a piloted input
shaft adjuster and input cover design. This change was made to address premature retainer bolt failures and excessive
radial play between the input adjuster and cover. The piloted design can be visually identified by the portion of threads
that have been removed from the adjuster and cover and replaced by a pilot. Additionally the current 8mm input adjuster
retaining capscrew has been replaced with a 12mm stud and jam nut. A part number reference listing is shown at the end
of this bulletin, pictured below are the new parts and detailed replacement procedures.
