2. FASTENING THE SUBFRAME TO THE CHASSIS FRAME
1) MOUNTING
a Use U-bolts to fasten the sub-frame to the chassis frame. Do not
fasten the bolts to the flanges of the chassis frame or weld the sub-
frame to the chassis frame.
b When there is little space between the U-bolts, use flat U-bolts (U-
plates).
2) SPACERS
a Spacers should be added to the places where U-bolts are used in
order to avoid warping the flange.
b In most cases, wooden spacers may be used. Near mufflers or in
other locations where there is a danger of wood catching fire, steel
spacers should be used.
c Use wood for spacers that is not easily warped by heat, etc.
Shrinkage may cause the U-bolts to come loose.
d The spacers should be designed to clear the brake pipes, fuel pipes
and the like.
