A reciprocating saw includes a housing assembly and a motor positioned substantially within the housing assembly. The motor includes a pinion. A drive mechanism is positioned substantially within the housing assembly and includes a gear driven by the pinion, a spindle, and a connecting rod to transmit rotation of the gear into reciprocation of the spindle. A bushing is positioned substantially within the housing assembly about at least a portion of the spindle. The bushing is pivotable relative to the housing assembly to accommodate non-linear rocking motion of the spindle. A seal surrounds a portion of the bushing and includes a first lip extending radially from the bushing and a second lip spaced apart from the first lip and extending radially from the bushing. The second lip is movable relative to the first lip. Both the first lip and the second lip continuously engage the housing assembly when the bushing pivots relative to the housing assembly.
