Ok let's see if this helps you ....The metal bearing has two holes in the side which take the two metal pins( they will probobly only go in one way they are normally worn at one end of each pin so gentle see which way they fit in ) this bearing then slips over the pump shaft , collar towards the pump, hole side up . The drive pin with the spring fits into the hole in the top of the metal bearing with the Spring sticking up . This is all on the pump side of the motor/ pump assembly. Now onto the motor side , ( your motor is not in the pictures but you'll need it to assemble these parts ) the diamond shaped cast housing fits on top of the drive motor and then the plastic drive plate and the small curved plate fit together with the plate inside the plastic drive to hold it by Spring tention onto the motor drive shaft . Then when you attach the pump onto the motor you have to locate Spring sticking up from the pump bearing into a hole on the motors plastic drive plate , any of the holes will do, then bolt the assembled back together. Sounds easy but you may have to try several times . Personally I find it easy to leave the pump and bearing on the bench with the drive pin and Spring sticking up and lower the motor and plastic drive plate half onto the Spring and pin and then twist the two halfs together to align to bolt holes and bolt together . Hope that helps ?
