❏ The gap between the magnet mount and sensor must be 3/8”-1/2”
(10-13mm). There should be a clearance zone of at least 3/4” (19mm)
above the drive shaft where the magnet is mounted.
! Place the magnet in its mount, then slide the large tie wrap through the
magnet mount to keep the magnet in place as shown below.
" Loosely cinch the large tie wrap around the CV joint with the magnet mount
oriented as shown.

installing the reed switch.
I‚‡r) Do not overlap the CV-joint boot with tie wrap.
I‚‡r) Do not mount the bracket on the vehicle chassis because of engine torque.
I‚‡r) Do not use fluid retaining bolts to retain the brackets.

Refer to these guidelines when you mount the speed sensor. The illustration on
the following page shows a typical bracket assembly. Due to the variations in
individual vehicles, adapt the bracket as necessary to fit your particular vehicle
and to maintain the required gap between the speed sensor and the magnet.
