Owner Kenneth Beene performed a major overhaul on
this engine (O320-E3D; L-29634-27A) in January 1998. Tear down and inspection after it was removed
from service on N664FL at 2222 hrs TT indicated a failing camshaft and lifters
on #1 & #2 intake lobs. It was
attached to RV-6 N94KB and first run in October 1999 for initial pressure
tests. Overhaul was in accordance with
Lycoming manual 60294-7 with modifications according to STC: SE3692SW, which
increases the HP to 160. All machine
work was done by Bolduc Aviation, Anoka County Airport, Minnesota. The following parts were replaced with new
except for the fuel pump, cam followers and vacuum pump, which are rebuilt with
yellow tags.
