ISSPRO MAGNET KITS
R8911 (¼” square)
INSTALLATION INSTRUCTIONS
Other materials required: Alcohol, a clean rag, and emery cloth or coarse sandpaper
WORK SAFELY: Park the vehicle on a flat surface, set the parking brake. Block up the front of the vehicle, if
necessary, to access the engine harmonic balancer, damper or pulley. A splash pan may have to be removed on
some vehicles.
PREPARE SURFACE: Locate a mounting position for the sensor. Select areas for the two magnets (on the
balancer, damper or pulley) which are directly across (180º) from each other and pass directly beneath the point
where the sensor tip will be located. Do a thorough inspection to ensure magnets won’t obstruct or pass close to
existing sensors. Scrape away the paint and roughen the metal with emery cloth (or sandpaper) at the two
selected areas. Clean the roughened areas and magnets with alcohol so that the glue will bond.
ORIENT MAGNETS – IMPORTANT: Magnets must always be mounted on pulley, damper or balancer with
blue side out!
NEW MAGNET INSTALLATION: Glue each magnet to the selected surface of the pulley or damper with the
magnets directly across (180º) from each other to maintain balance.
Suggested method for glue application:
Apply the glue to the area on the damper where the magnet will set, then apply the accelerant (crush tube)
to the magnet face (non-blue side), then apply the magnet to glue area on damper. Be sure to apply
enough glue to fill the gap between damper and magnet. Repeat for other magnet. Let glue set for 10-15
minutes. Follow the instructions on the glue packet enclosed in your kit to allow the proper glue curing
time before starting the engine.
REPLACING LOST MAGNET: Locate the area where the magnet was lost, chip off the old glue, then roughen
the area with emery cloth (or coarse sandpaper). Clean the area and the new magnet with alcohol and a clean rag
so that the glue will bond. Follow the remainder of the instructions from the “ORIENT MAGNETS” section.
INSTALL SENSORS: Install the sensor so there is approximately ⅛” to ¼” clearance between the sensor tip and
the magnet. Do not bend the sensor bracket at the sensor end as this could cause the sensor to break free of the
bracket. The sensor-magnet clearance is not critical, but should not be so small that a magnet contacts the sensor
at any time. If erratic pointer movement on Tach, move sensor further from magnets.
