Improper assembly when replacing the Bearings (251-82) and the Spacer (87-2750) can cause early
failure of the APU Shaft Bearings and Spacer. Spacer (87-2750) should be inspected for correct length
to ensure intended bearing support. Refer to the Installation Instructions below
for correct assembly procedure and part specification data.
