I'm trying to repair a hammer drill for a buddy. The unit is leaking grease near the cooling fins and near the chuck. I would think there is a seal or two bad. The big question is, is it very hard to repair? and are there any things I need to look for when disassembling this unit. I never done one before but have repaired many other tools so the challenge is to do it right.
If you can help that would be great.
