Alternator Installation

The alternator is factory-installed by the engine manufacturer (Lycoming) using Lycoming mounting
brackets. Removal and installation instructions may be found in the appropriate vendor service
publication or in the instructions / drawings for Lycoming Kit No. 05J22487.
With a belt installed, align alternator idler pulley in the belt plane by adding or removing shims
between the alternator mounting ears and the alternator mounting bracket. (See 21-50-00, Figure
13.)

Alternator Belt Tension Adjustment

(1) Loosen bottom mounting bolt and belt adjusting bolt. Adjust alternator belt tension by
applying pressure to the adjusting lug of alternator with a one-inch open end wrench. Use a
calibrated belt tension gauge to adjust a new belt to 90 - 120 pounds of static tension. Run in
for 15 minutes. If tension falls below 50 lbs., re-tension to 70 lbs.
CAUTION: IF AIR CONDITIONER IS OPERATED ON THE GROUND FOR
(2) Run engine 15 minutes at 1200 rpm.
(3) Shut down engine, remove engine cowling, and check both belt tensions.
(4) Check all idler and bracket bolts for safety. After tension is set and upper bolt safetied, tighten
lower mounting bolt 450 to 500 lb.-in. There should be no end play in alternator mount. Add
thin washers between alternator and mount to remove end play.
(5) Install engine cowling.
(6) Re-check tension every 100 hours or annual inspection, whichever comes first.
2. Battery (See Figure 22 and see also 12-10-00.)
The battery is located in the aft fuselage, aft of the rear baggage compartment. Access to the battery is
through the aft fuselage access panel in the rear baggage compartment, below the hat shelf.
The manifold-type battery and its associated acid recovery sump jar are shelf mounted. Fumes
accumulated from the natural charging process are vented to the outside of the aircraft, through the
sump jar. This vent must be checked for corrosion. The battery manifold drains into the acid recovery
sump jar through the manifold overflow/vent line. The sump jar vents through the fuselage vent line
connected to a vent located on the bottom of the fuselage.
The battery should be checked for fluid level, but must not be filled above the baffle plates. A hydrometer
check should be performed to determine the percent of charge in the battery. All connections must be
clean and tight. If the battery is not up to normal charge, remove it from the airplane and recharge.
