b. LSI Sensor Installation
1. Ensure threads of both bolt holes are clean and free
from rust, water and debris.
2. Clean the bare metal with a degreasing agent, Loctite
®
7063.
3. Remove any excess degreasing agent and allow to dry.
4. Apply a thin film of Loctite
®
Initiator #1 (may also be
denoted as Initiator #5) activator approximately 6 cm² (1
in²) to the two flat metal surfaces (8) of the sensor,
ensuring the adhesive is spread evenly over the entire
surface.
Note: Follow all adhesive manufacturer’s recommendations
including storage life.
5. Apply an 3mm (0.125 in) bead of Loctite
®
A2460
Adhesive to each metallic mounting pad (9) on the
sensor. The bead should center on the mounting hole
and be equally spaced between the hole and the edge
of the mounting pad as shown above.
6. Do Not spread the bead prior to mounting the sensor.
7. Fit the sensor, ensuring the lead exits in the corner
direction. Secure with two new bolts - Socket HD
Capscrew M10x35x1.5, Grade 12.9.
Note: It is important to prevent distortion of the sensor
element, therefore tighten each bolt finger tight. Alternately
tighten each bolt to 35 Nm (26 lb-ft) and finally to 70-80 Nm
(52-59 lb-ft).
8. Permanently mark position of bolt head and sensor
body.
