so i have the 870 k loader from rc4wd and i had them send me a new pump motor and when i paid for it lol i then compared them and the new one i got was for the 4200 excavator and it was alot biger than the one in the 870 alot bigger both in the size and in the shaft size that goes in the pump i figured i will use the bigger pump motor in a screening plant i want to build
