I'm attempting to repair a cheap pressure washer which quit working after
just using it a few times. Karcher ( the manufacturer of this piece of junk
) does not appear to offer replacement parts only exchange on units which
are still in warranty . 
I've found the problem, the plastic ball bearing cage is chewed up. The
bearing ride on a wobble cam and operate the cylinders that pressurize the
water. 
The wobble cam has a groove that the bearings ride in and the top plate
(race) is spring loaded to sandwich the ball bearings in place ( in the
groove). 
Well my question,  do you think I could simply not use the cage to evenly
locate the ball bearings around the cam and instead use more ball bearings
so they remain evenly spaced?
( Simply put does the cage in a ball bearing unit function only to space the
bearings and can packing more ball bearings into the unit substitute for
using a cage?)
