SEAL 1989428 - Caterpillar

+
Determine the location for the placement of the Product Link. Before you weld or before you drill, check that the location will not invalidate the structure certification for the following items: ROPS, FOPS and other protective structures. Refer to Special Instruction, SEHS6929, "Inspection, Maintenance and Repair of Rollover Protective Structures (ROPS) and Attachment Installation Guidelines" as well as any other published guidelines that are specific for a serial number.
Do NOT install the unit in the following locations:
Do not attach to the underside of the machine.
Do not attach in a location that obstructs the view of the operator.
Do not attach to the ROPS by drilling holes through the structure.
Do not attach to the ROPS by welding to the structure.
Do not attach to the roof, unless no other location is available.
Do not attach if there is any exposure to water.
Do not attach with connectors that point upward in order to avoid collecting water.
Do not attach to a location that is subject to abrasion by debris.
Do not attach in the engine compartment unless the factory is in approval.
Structural damage, an overturn, modification, alteration, or improper repair can impair this structure's protection capability thereby voiding this certification. Do not weld on or drill holes in the structure. Consult a Caterpillar dealer to determine this structure's limitations without voiding its certification.
When you select the location, remember the following consideration:
The Product Link Module will be connected to an antenna that is mounted on the roof. Keep the routing of the cable in mind. The length of the antenna cable is 6.07 m (20 ft) or 0.91 m (3 ft).
The antenna cable must not be routed near the exhaust system.
The antenna cable must not be bent sharply.
Determine if the shock mounting will be used. Shock mounting is required on all track-type vehicles. On all other machines, shock mounts are not required if the unit is being installed in a cab that has shock mounts. If the unit is being installed outside the cab or if the cab does not have shock mounts, the shock mounts must be used.

Dimensions For Attaching Weld Bosses For The Product Link
If the mounting location is thick metal or if drilling holes is not desired, attach the four 4E-8266 Bosses in the pattern that is shown in Illustration 3. Note the different measurements for non-shock mounted units. If the mounting location is not metal or if drilling holes is easy, drill four 6.35 mm (0.25 inch) holes through the mounting surface.

Assemble the shock mounting components. Push a 8C-5607 Mount (1) into the 15 mm (0.59 inch) hole in each side of the 170-9198 Plate (2). Slide a 8C-5608 Spacer (3) inside the two mounts. Repeat this procedure for the remaining three holes.
