BOOM SHIMMING PROCEDURE
NOTE:
Throughout this procedure, boom sections are identified
numerically, 1-5. Boom Section 1 is at the base, Boom Sec-
tion 5 is the fly.
1.
Measure and record any sweep dimension and direction
of Boom Section 5 per spec drawing 1280284 and
record in Quality logbook. Measure and record the
inside width and inside height of the Boom Section 4
opening.
2.
Install the Internal Side wear pads on the Section 5 sides
and shim as required to match the corresponding
dimension recorded in step 1 within plus or minus 1/32”.
Shims should be divided as evenly as possible between
the side pads unless corrections are needed to compen-
sate for any sweep recorded in step 1. If the sweep is to
the left the internal side pads on the right should have
more shims than the left side pads and vice-versa.
NOTE:
When installing wear pads in the following steps, the wear
pad bolt lengths may need to be adjusted as shim thick-
nesses are adjusted. Bolt lengths should be flush to one
thread below the surface of the insert.
3.
Install the bottom wear pad(s) on Section 5 boom as
specified on the boom assembly drawing.
4.
Install the top wear pad(s) on Section 5 boom and shim
as required to obtain the total dimension 0” to1/16”
under the corresponding dimension in step 1.
5.
Slide Section 5 into Section 4 with 2 to 6 feet exposed.
6.
Install the bottom wear pad(s) onto the end of Section 4
as specified on the boom assembly drawing.
7.
Temporarily insert the External Side pads on one side
and slide Section 5 boom to that side. Insert the other
side pads using shims measure how many will be
required to fill the remaining space. Once this is estab-
lished, install the total amount of shims as evenly as pos-
sible between the two sides unless corrections are
needed to compensate for out of square booms or for
additional corrections for any sweep recorded in step 1.
Care should be taken to keep the bottom pads evenly
loaded while shimming the side pads. If the sweep is to
the left the external side pads on the left should have
more shims than the right side pads and vice-versa.
NOTE:
Do not use a wedge to install more shims than will fit with
the use of a pry bar. This may result in a boom being
shimmed too tight. The use of pry bars should only be used
to finish installing a shim that can be installed by hand
more than ½ of its length.
8.
Install the top wear pads and shims into the end of Sec-
tion 4 leaving a gap of 0” to 1/16” between the top of
the Section 5 and the pad inside Section 4.
