NOTE: If a reinforcement channel is required, the
top and bottom flanges should be 0.250 inches nar-
rower than the side rail flanges. Weld only in the
areas indicated (Fig. 8).
FRAME FASTENERS
Bolts, nuts and rivets can be used to repair frames
or to install a reinforcement section on the frame.
Bolts can be used in place of rivets. When replacing
rivets with bolts, install the next larger size diameter
bolt to assure proper fit. If necessary, ream the hole
out just enough to sufficiently receive the bolt.
Conical-type washers are preferred over the split-
ring type lock washers. Normally, grade-5 bolts are
adequate for frame repair. Grade-3 bolts or softer
should not be used. Tightening bolts/nuts with the
correct torque, refer to the Introduction Group at the
front of this manual for tightening information.
