is 133 shiped a bad price for the JUN collar?
read the writeup a bit more carefully. in order to install the collar you need to remove the crank. if you remove the crank you typically want to use new fasteners, in which case may change your big end tolerances, requiring new bearings. then you might as well build the bottom end.
if you plan to fix the crank collar, i would rebuild the motor.
if you don't want to rebuild the motor yet, just get a new pump and put it on.
