5.6 Installing Underside Covers
The underside covers are an accessory item ordered to specification per BSBAC mark. The underside
covers are shipped separately on a skid. The only exception is the underside covers installed on the
BSBAC drive sections.
The overall width of the underside cover is approximately 1/8" less than the between frame width of the
BSBAC section. All underside covers supplied come with underside cover splice plates for installation.
The order of installing underside covers is as follows:
1. Drive section.
2. Tail Section.
3. Noseover Section – if applicable
4. Bed section.
The following instructions outline the operational procedure to install underside covers.
1. Identify the underside cover for the installed BSBAC section.
2. It is recommended to install (1) splice plate at every corner of the underside cover and at least (1)
splice plate every 36" on each side. Refer to Figure 20 that shows an exploded view of the splice
plate install on the side covers. The splice plate is installed using 3/8" carriage bolt and serrated
flange nut. The torque requirement for the 3/8" carriage bolt and serrated flange nut is 31 ft-lbs.
