Repairing a growling Marcrist DDM3 Wet and Dry diamond core drill with a bad bearing and seals.

These Marcrist DDM3 and DDM2 core drill where quite popular at a time.
But I see them less and less now since marcrist stopped selling them.
They where a good enough machine for the job, but I always found repairing them very expensive.

This one in not all that expensive a repair for a change, the second hand housing has helped keep the costs down. But if you need the seals replaced in yours, your best bet js to remove them, read the size and order them from a specialist seal supplier.
