Standard replacement double row bearing for all manual gearboxes with large type double row bearings, and is also used on auto gearboxes as the input shaft support bearing. This heavy duty bearing recieves the most abuse and thus it is critical that it is not worn. If the plastic retainers or balls show any sign of damage, wear, or noise, this bearing should be replaced. 
 
Not supplied with outer circlip, reuse your old one.
