    Hi all

    Anybody had or know of new or old pumps having problems with new oil from suppliers i.e. Seizing up etc?

    Not heard of much trouble with Riellos lately.
    Got to check the oil filter on oil line isn't nearly blocked to cause oil pump to seize.
    Any sign of water inside pump?
    I did see one job many years ago where the kerosine delivery contained a lot of water

    get a gauge on and see if the pump is pulsing, then check for air in the oil supply.

    Yes, quite a few. Caused by reduced sulphur content in oil.

    Read some place that suppliers were adding certain amounts of bio fuel which were playing a bit of havoc with some!

    Reducing Sulphur content also reduced the lubricating properties of the oil. I've had a few were seal on pump fails, throws oil into motor, softens coating on windings, motor fails, mess made by leaking oil.
