B&M 80885 HAMMER SHIFTER - Manual

The B&M Hammer shifter can be used in
vehicles equipped with most popular three
speed or four speed automatic transmissions.
Your B&M Hammer comes equipped with
Neutral safety and backup light switches,
transmission brackets and levers and a five
foot shift cable. Optional shifter cables in 2 ft.
(80830), 3 ft.(80831), 4 ft.(80832), 8
ft.(80834), 10 ft.(80835) and 12 ft. (80836)
are also available. To use the B&M Hammer
with the Ford AOD transmissions you will
need optional accessory kit #40496. To use
the B&M Hammer with a GM 4L80E or 4L85E
transmission equipped with a PRNDL switch
you will need the optional accessory kit #75498
otherwise you can use the GM bracket sup-
plied.
To use this shifter with a GM four speed
automatic transmission (TH-700R4, TH-200
4R, 4L60,4L80E or 4L85E) you will need to
remove the three speed blocker bolt and nut.
(See figures 1 and 3.) For the Ford AOD four
speed transmission do not remove this bolt.
Please read the instructions and review
the illustrations thoroughly before beginning
the installation.
The mechanical components of this shifter
are precision made and assembled at our
factory. Any modification or disassembly of
these parts can cause the shifter to malfunc-
tion and will void the warranty. You should
disassemble only those items outlined in the
instructions.
The vehicle should be about 2 feet off the
ground for ease of installation. Use jack stands,
wheel ramps or a vehicle lift. Make sure the
vehicle is firmly supported before attempting
to work on it.
IMPORTANT: If your vehicle is equipped with
a locking steering column, securing the col-
umn lock lever in the engine compartment in
the full up position will allow the steering wheel
to be locked and unlocked and the ignition key
to be removed.
WARNING: This allows the steering wheel to
be locked WHENEVER the ignition key is turned
to the “lock” position WHILE THE VEHICLE IS
MOVING, OR AT ANY OTHER TIME. Securing
the steering column lock lever in any other
position will both PREVENT the steering wheel
from locking and removal of the ignition key.
INSTALLATION
NOTE: If you are installing this shifter with a GM
TH-700R4, TH-200 4R, 4L60, 4L80E or a
4L85E four speed automatic transmission you
must remove the bolt and nut indicated in
figures 1 and 3. Removing this bolt gives the
shifter four forward positions rather than
three. For Ford AOD four speed transmissions
do not remove this bolt and nut, since this
transmission has only three forward posi-
tions. Also do not remove the bolt and nut for
three speed automatic transmissions.
STEP 1.
Remove stock shift linkage;
Column Shifters: Remove all rods, levers or
cables from column and transmission. Place
column shift lever in “Park” position. Remove
pin holding shift lever in column and remove
lever assembly. If your vehicle is equipped
with a locking steering column, secure the
column lock lever in the full up position. WARN-
ING: This allows the steering wheel to be
locked and ignition key removed WHENEVER
the ignition key is turned to the “lock” position
WHILE THE VEHICLE IS MOVING, OR AT
ANY OTHER TIME.
Console Shifters: Remove shifter mecha-
nism from console. Disconnect rod or cable
from transmission. Remove cable bracket if
equipped. If there is a cable or linkage from the
console shifter or transmission to the steering
column lock, it must be blocked in the “Park”
position as described above.
NOTE: Shifter installation may require con-
sole modification or complete console removal
depending on the space available in your
vehicle.
STEP 2. Pull the carpet away from the floor-
board where the shifter is to be mounted. If the
vehicle has a bench type seat, move seat to
the full forward position. Place the shifter on
the floor with the stick shifted to the rearmost
gate position. Locate the shifter for ease and
convenience of operation, See figure 2. Make
sure the trigger and T-handle clear the dash
with the shifter in the “Park” position. Mark the
position of four mounting holes on the floor.
STEP 3. Drill four 9/32" mounting holes
where marked. Temporarily mount the shifter
in place using washers as required to get it
level. Do not bend mounting brackets on
bottom of shifter. Mark the location for the
shifter cable hole, 3" ahead of the left front
shifter mounting hole. Drill or cut 1-1/2" diam-
eter cable hole in floorboard. NOTE: Some
floorboards are extremely thin and will not
adequately support the shifter mechanism
when bolted to the floor. For those vehicles we
recommend that you fabricate a stiffener plate
for additional strength.
STEP 4. Install (but do not secure) carpet
back to it’s original position. Cut holes in the
carpet for the mounting holes and cable. DO
NOT use a drill bit to make holes in carpet.
STEP 5. Assemble Neutral Safety and Re-
verse light switches to bracket using two #4-
40 x 1" screws and nuts, as shown in figure
1. Beware, Over tightening the switch attach-
ment screws will crack the switch housings.
Install Switch assembly on shifter. To adjust
switches loosen screws and slide switches in
or out as required, then retighten screws.
STEP 6. Install cable on shifter as shown in
figure 1. The cable attachment tab should be
bolted to the outside surface of the shifter
base using 1/4" x 1/2" hex bolt, lock washer
and nut. Install the E-Ring that secures the
cable to the cable pin.
STEP 7. Before the final installation of the
shifter in the vehicle, add longer wires to the
indicator light (LED) and attach the indicator
cable to the side of the shifter. Attach longer
wires to the indicator light leads, use butt
splices or solder and tape the wires. The
extension wires should be color coded or
marked, since they must be connected with
the correct polarity. The black wire must go to
ground and the red wire must go to a 12 volt
positive (+) supply. The LED will not illuminate
if they are connected backwards. The red
