Product review (4 stars): Easy Repair
The product had a different color package and brand than shown (brand name Supco).  Mine came with the cup, 4 cam dogs, retainer ring, o-ring for cap, and rubber washer for bolt.  It did not include instructions.  Fortunately for me I am technically inclined enough to both search the internet for how to videos and complete the task without coaching.

It repaired the agitator in my 1994 Roper RAL5144AW0 washing machine to proper operation.  Including grease and instructions would have been very helpful.  The local repair parts place wanted over 20 for this kit.  Worth every penny.
