ENGINE EXHAUST

(1) REMOVAL

(a) Remove the cowl as described in section 6.3.14.
(b) Disconnect all of the SCAT ducts from the heat shrouds by loosening the hose
clamps.
(c) Remove the forward induction elbow on each side of the engine. Do this by
loosening the winged hose clamps and sliding the rubber couple inboard along
the induction tube. Remove the nuts and washers holding the elbows to the
engine. Set the elbows aside.
(d) Remove the nuts that attach the exhaust flanges to the engine cylinders and
lower the exhaust system away from the engine.

(2) INSPECTION

(a) Inspect the components of the exhaust system for signs of cracking. Have any
cracks repaired by an FAA-approved or Cub Crafters-approved repair facility. If
the cracking is excessive, replace the exhaust system component(s).
CRACKS IN THE EXHAUST SYSTEM WILL ALLOW CARBON MONOXIDE TO BE
PRESENT INSIDE THE COWL. THIS MAY TRAVEL THROUGH THE FIREWALL AND INTO
THE COCKPIT. CARBON MONOXIDE MAY RESULT IN DEATH. NEVER OPERATE THE
AIRCRAFT WITH ANY CRACKS IN THE EXHAUST SYSTEM.

(3) INSTALLATION

(a) Install the exhaust system in the reverse order that it was removed in. Replace
the gaskets on both the exhaust flanges and on the induction elbows. Torque the
nuts on the engine cylinders as specified in the Teledyne Continental overhaul
manual.
