Hi All, I'm trying to convert a couple of USA spec. HP 7914 hard drives to UK spec. This involves not only changing the input tappings from 110 Volts to 240 volts but also changing the main drive pulley and drive belt to compensate for 60 Hz / 50 Hz mains frequency difference. Machining up a revised (larger) pulley isn't a problem but finding the drive belt is proving difficult. Is there anyone on list that has the necessary parts (perhaps a scrapped drive in the UK)? I think that the parts are common for the 7911, 7912 and 7914 drives - the HP part number for the belt and pulley are - 07912-20013 (pulley) and 07912-40018 (drive belt). Does anyone have experience of these drives? The pair that I have are quite grubby on the outside, have probably been knocked about a bit in transit but have had the spindles locked and the head leaver in the 'locked' position - is it likely that they will still work?
