the ford class “a” motorhome chassis is
supplied in several wheelbase lengths. the
standard length is a 178” wheelbase. longer
wheelbase coaches will require an additional
extension pipe. these are available from gale
banks engineering in a 33” and 53” length
to fit 208” and 228” wheelbase coaches,
respectively. other wheelbase coaches may
be accommodated by cutting one of these two
extension pipes.
extension pipes are required to fit wheelbase lengths
as follows:
178” wheelbase
no additional extension pipe required.
(use 28” extension pipe supplied in all kits.)
179-208” wheelbase
requires 33” additional extension pipe.
209-228” wheelbase
requires 53” additional extension pipe.
229-258” wheelbase
requires 33” and 53” extension pipes.
install the appropriate additional extension pipe(s) if
required. Wheelbases other than 208 or 228 inches will
require that the extension pipe be shortened to place
the rear muffler hanger u-clamp over the center of the
muffler outlet. check by installing the 3 1 ⁄
2
” u-clamp with
hanger bracket into the original muffler hanger mount
on the chassis and measuring forward. See Figure 6 .
rotate muffler on extension pipe to place outlet
in line with 3 1 ⁄
2
” u-clamp hanger. install muffler
on extension pipe. temporarily support rear of muffler
in 3 1 ⁄
2
” u-clamp hanger.
31.
install tailpipe in muffler outlet. note that end of
tailpipe with bend close to end goes into the
muffler. See Figure 6 . do not tighten hanger u-clamp
at muffler outlet at this time.
32.
install 3 1 ⁄
2
” u-clamp and universal hanger
bracket to support the outlet end of the tailpipe.
because there are many coach configurations, the
installer will need to choose a suitable location from
which to hang the universal hanger. the hanger should
be attached to some part of the metal frame structure
if possible. if the optional chrome tailpipe tip is to be
installed, make sure the hanger will allow the tip to be
slid far enough onto the tailpipe so as not to hit the
hanger u-clamp. a 3 ⁄
8
–16 x 1 1 ⁄
4
hex bolt, 3 ⁄
8
–16 locknut,
two 3 ⁄
8
washers are provided. shorten the hanger strap
as required to allow the tailpipe to clear the coach
body and run level if possible. See CAution
concerning heat shielding in later section.
33.
install the chrome tip and chrome tailpipe heat
shield on the tailpipe as shown in figure 6 . tip
may be slid in or out on the tailpipe to match the body
width.
NOTE: If possible, leave tailpipe within 2” of end of chrome
tip inside the tip. This will protect the chrome from
changing color from high exhaust heat. Shorten tailpipe if
required.
34.
once all piping has been installed and adjusted for
position, tighten all u-clamps.
35.
if extension pipes are not supplied with heat
shields welded in place, separate clamp-on heat
shields will have been provided. install the short heat
shield on the 28” extension pipe as shown in Figures 6
and 7 . heat shields install with the shield at the top, to
protect the coach floor.
