match the hole in the front housing to prevent coil
movement and the lead wire must be correctly lo-
cated.

2. Support the compressor on the four mounting ears at
the compressor rear side. If using a vise, clamp only
the mounting ears, never the compressor body itself.
Align the rotor assembly squarely on the front hous-
ing hub.
Using a hammer and a special tool, tap until the rotor
bottoms to the compressor front housing hub.
3. Reinstall the internal bearing snap ring.
