2. Apply clean compressor oil to the new O-ring
and install it in the seal plate. Apply clean
compressor oil to the new hard ring. Ensure
that the hard ring installation tool
(P/N 204-953) is clean. Use the hard ring
installation tool to push the hard ring (with the
polished surface toward the installation tool)
fully into the seal plate. Do not pinch the
O-ring.
3. If the installation tool is not available, use the
pad in the new seal packaging to protect the
polished surface of the hard ring during
assembly.
NOTE: Do not replace the internal lip seal
unless it is damaged. To replace it, pry the old
one out and press the new one into place with
the lip facing into the seal plate. Make sure
the lip seal is pressed all the way down into
the seal plate. Oil the lip seal.
4. Apply clean compressor oil to the O-ring
inside the bellows. Slide the bellows on the
crankshaft, align the hex drive on the bellows
with the hex drive collar, and then push the
bellows firmly against the hex drive collar.
Leave the protective cap in place during
installation. If the hex drive does not slide on
easily, rotate the assembly 30 degrees.
