I recommend anything with the XPR transmissions (but the Hammer Drill versions are not value added so avoid them) Specifically:
DC980KA (12V version)
DC983KA (14.4V version)
DC987KA (18V version)
The parts you need are at the link for service parts above.
I have set up a sham account: login: "chiefdelphi" pswd: "team47"
Go to "saved orders" look under "FIRST ORDER" It totals a bit over $100 for the lot (including a motor).
Mike Martus is working hard on the whitepaper. I am pedalling as fast as I can.
We will get things up as soon as we can.
This is a link to a PDF file showing an exploded view of the DC980KA drill and the associated part numbers.
