The pump builds up pressuer to 80 to100 psithe motor cant turn any more due the pressuer in the pump, can you tell me why this happens dayton compressor model 5Z592 5hp it had a 3phase motor when it was new, i got it with a 1phase motor model hdn56mrb34d51 5hp volt 208-230. the compressor sat outside under a carport before i got, put it together. hooked it up, first time the motor stoped at 80psi got very hot so i changed pump oil. got it up 100 psi the the motor stoped again. i took the air tube that goes from the head to the tank, checked for restriction, also did the same to the tube from the tank to the pressure switch none found, new pressure switch was installed also. pump turns easy with no pressure by hand. its very hard to turn with pressure. pump sounds good when it runing. hope you can help joe.
