My machines 200psi pumptec pump burnt out on me on friday. I ordered a replacement electric motor as head is spare i had,which arrived today ouch postage. Opened the box and first thought I'd been sent the wrong motor. Was advised that this is the new improved motor as the older ones burnt the armeture. Fitted with fingers crossed and once i switshed it on all i get is a humming noise a bit like a set of hair clippers!! Any thoughts?? I've checked pumptec site and from what i can see the head and said motor are compatiable. M72 motor and 112 head. Could it be that the cam bearing isn't engaged in the head??
Powerflight pfx 1350
Lost of ideas at the moment anybody in the Manchester area could help out??
