INSTALLATION
CRANE INSTALLATION
Mainframe and subframe are very heavy
components (7000lbs and 3000lbs
respectively) and caution should be used
as well as proper lifting devices.
1. Assemble the mounting tiedown bolts for
each corner of the mainframe and for the aux­
iliary outriggers. Assembly includes:
tiedowns, hardened flat washers, jam nuts,
and lock nuts. Drive the lock nuts onto the
tiedown bolts and lock into place with the jam
nut on top of the lock nut.
An acceptable method of getting the lock
nuts on the bolt is to clamp the bolt in a vise
and turn the nut with an impact wrench.
Note: Make sure the threads are free of
contamination and damage, and are
properly lubricated, or galling may occur.
2. When all mounting preparation is com­
plete, the subframe should be placed on the
truck frame as determined by your frame stiff­
ener placement.
3. Install the auxiliary outriggers as illus­
trated on the Aux. Outrigger Install drawing.
Make sure to center on the frame stiffeners.
The outrigger assembly can be lifted into
place with two lifting straps, one on either side
of the subframe. The auxiliary outrigger clamp
plates are installed over the top of the sub­
frame. Using an impact wrench, snug the
tiedown bolts evenly.
4. Connect the auxiliary outrigger hoses to
the vertical outrigger jacks and the electric
selector valve. These typically consist of 3/8"
hoses for the jacks, 3/8" for the selector valve
supply and 1/2" for the selector valve return.
Keep track of each hose and it's connec­
tion to be sure of connecting them correcty
during mainframe installation
5. Bring in mainframe and place in position
on subframe as per the M/F Turret installation
drawing. The use of alignment pins in the
tiedown holes will facilitate mainframe place­
ment and hole alignment.
6. Insert the tiedown bolts into the clamp
bars, and insert the assembly , from the bot­
tom of the truck frame, and through the main­
frame mounting holes as shown below.
Thread a lock nut onto each tiedown bolt.
When all four clamp bar assemblies are
installed, snug up the tiedown nuts.
