  • Prazi SD300 lubrication question

    Hi all,
    I need help on how to lubricate my Prazi SD300. I know how to lube most components but haven’t figured out how to lube the following:

    -Leadscrew thrust and slide bearings

    -Drivetrain stepped V belt pulley – the manual shows it is to be oiled before every use but there is no oil hole or lube fitting.
    This pulley can be taken off its shaft by removing a snap ring but I wouldn’t think that would be done before every use. So how is it supposed to be lubed?

    -Are there any other lube points in the drive train?

    Thanks,
    henryr

    I am not familiar with the Prazi SD300 (East German I think).
    You say there is no way to lube lube the stepped pulley. Is it a sealed bearing?
    What do the lead screw bearing consist of?
    If you could post a few clear pictures of the areas in question perhaps it could give us all some better insight into your question and allow us to help you better.

      I learned that there are two sealed bearings on the pulley holder shaft.
