The #8055CA is the same as the 8055 part. This kit includes snap ring and nut and it attaches to the 8054 Actuator Bracket Assembly. If any of these parts fail, it is a good idea to order both the 8055CA AND the 8054 at the same time.
DISCONTINUED PART NOTICE:
The original MEC part, #8053, has been replaced by #1308054, which also includes the cam roller kit set screw. If this part goes bad on your loader, please also look at replacing the #1308055 operating rod as well.
