The Delco Remy 40SI brushless alternator design dramatically increases both the durability and the life of the alternator. Here’s why: Brushless alternators have fewer moving parts, which means less wear on the alternator. The end result is longer life. Alternators pull air from the back to the front in order to cool the internal electronics.

PULLEY INSTRUCTIONS: Use pulley from old alternator if this alternator does not have one or pulley supplied is different from pulley
on alternator being replaced. NOTICE! When changing the pulley, keep the alternator shaft in the horizontal position and do not
apply any pressure to end of the shaft. Internal damage may occur if the shaft is pushed back and turned.All alternators are
shipped with spacers that go behind the pulley. During installation of the pulley, assure these parts are in the same order as
received. If the old alternator has different spacers, use them and Install on this alternator in same order as removed. Assure the
pulley turns freely prior to installation.
Hold the shaft by placing a hex wrench in the hexagonal hole in the shaft while removing or installing the pulley. Tighten the pulley nut
to 95-108 Nm (70-80 lb ft). Do not install the fan.
BELT TENSIONING INSTRUCTIONS: Improper belt tension can cause premature alternator failure. If the belt must
be tightened manually, place a wood block between the alternator and pry bar, as illustrated at right. Pry as close to
the center of the unit as possible. Use a torque wrench to tighten mounting bolts to the proper torque as specified in
vehicle or engine manufacturer’s specifications for belt tension and mounting bolts torque. DO NOT OVER TIGHTEN
BELT!

TERMINAL DESCRIPTIONS (Alternator will function without connecting the S, I or R terminals):
“B+” Terminal -Output terminal connects to the positive (+) battery terminal.
“S” Remote Sense™ Terminal – Connect to system voltage at the battery or a common distribution point.
“R” Terminal – Relay / Phase terminal carries half system voltage and may be used for certain types of control relays, charge
indicators, tachometers or similar devices. The current draw should not exceed four (4) amperes. Frequency = Alternator RPM/10.
Notice!
The “R” Terminal is not the Remote Sense™ terminal – do not connect to B+!
“I” Terminal - The Indicator lamp/ignition terminal can serve as a current source, sink or both, depending on how it is connected. The
diagram above shows one configuration. Current capability is 1.0 Amp in either direction.
Ground Screw
– Ground lead ensures alternator is grounded and is strongly recommended for optimum performance.

Note: Instructions for 24SI & 28SI toreplace 21SI, 22SI
& 24SI alternators are onthe www.delcoremy.com web site.
WARNING!!!!
ALWAYS USE PROPER EYE PROTECTION WHEN PERFORMING ANY MECHANICAL REPAIRS TO A VEHICLE
- INCLUDING, BUT NOT LIMITED TO, ANY INSTALLATION AND OR REPAIRS TO THE DELCO REMY
®
ALTERNATORS. FAILURE
TO USE PROPER EYE PROTECTION CAN LEAD TO SERIOUS AND PERMANENT EYE DAMAGE.
Only perform the mechanical functions that you are properly qualified to perform. Mechanical repairs that are beyond your technical
capabilities should be handled by a professional installation specialist.
DANGER!!!
To avoid injury or damage, always disconnect the negative cable at the battery before removing or replacing the alternator.
The alternator output terminal is always live (“hot”). If the battery is not disconnected, a tool accidentally touching this terminal and
ground can quickly get hot enough to burn skin or damage tools and surrounding parts.
NOTICE!
Some of these are extremely high output Alternators. Always ensure your application is equipped with the appropriate
size and gauge cable. CHARGING LINE CABLE VOLTAGE DROP SHOULD NOT EXCEED 0.5 VOLTS (12V system), 1.0 Volts
(24V system) (ALTERNATOR OUTPUT [B+] TERMINAL TO BATTERY POSITIVE TERMINAL AT FULL OUTPUT). FOR
OBTAINING ADDITIONAL WIRING INSTALLATION INFORMATION, SEE HEAVY DUTY APPLICATION MANUALS OR
CONTACT A REMY INC. REPRESENTATIVE.
FOLLOW ENGINE OR VEHICLE MANUFACTURER’S INSTRUCTIONS FOR REMOVING THE OLD ALTERNATOR FROM THE
ENGINE AND INSTALLING THE NEW ALTERNATOR.
REMOVAL & INSTALLATION INSTRUCTIONS
Disconnect the negative (-) cable at the batteries.
Identify and tag all leads when removing the old alternator and install them on the same terminals of the new alternator.
Insure all leads are reconnected or contained where they cannot ground.
Torque all fasteners to values labeled in Figures 1, 2 & 3
This alternator may have more terminals than the one being replaced had or used. It will charge properly with only the battery and
ground leads connected. Use of the other terminals is optional based on need. See “TERMINAL DESCRIPTIONS”, Pages 2 and 3.
