IDENTIFYING GAPS BETWEEN THE CBC AND THE VEHICLE BED

Once the CBC is in its final mounting position on the vehicle bed, the weather stripping seal must be

inspected in order to detect any gaps that may exist between the weather stripping (1) on the underside

of the mounting plate and the vehicle bed (2). These gaps are typically caused by dents and other

irregularities in the surface of the vehicle bed.

To inspect the quality of the weather stripping seal, have a person with a flashlight enter the CBC,

partially close the personnel door, and shine the light along the bottom of the mounting plate where the

weather stripping and vehicle bed meet.

On the outside of the CBC, use chalk, masking tape, or other temporary marking instrument, and mark

those areas of the CBC where light shines through and gaps can be seen. To inspect the quality of the

weather stripping seal at the front of the CBC, it will be necessary to enter the CBC and conduct the

inspection from the inside.

Estimate the width of each gap area in order to determine whether 3/16 inch or 1/8 inch weather stripping

is required to properly fill the gap. Make a note of the thickness required with chalk or on a piece of

masking tape placed in the area of the gap. Note that in some cases in may be necessary to use some

combination of both sizes of weather stripping in order to properly close the gap.

Once the gaps have been identified and marked, remove the two bolts temporarily securing the gusset

plates and raise the CBC using the hoisting sling to a comfortable working height and apply additional

weather stripping in the marked areas.

When the additional weather stripping has been installed, lower the CBC back into position on the vehicle

bed. Inspect the quality of the seal using the method described above. If any gaps are still seen, mark the

areas and apply additional layers of weather stripping as required.

Continue this process until no gaps are present. Do not secure the CBC to the vehicle bed at this time.
