INTRODUCTION
MBW Inc. SCREED is intended for use in many applications. It offers the highest level of finishing consistency
available today. Precision machining of all components, combined with all bolted construction, are the key
factors for ease and speed of assembly and for true alignment job after job.
MBW Inc's exclusive 45 degree AĆframe cast aluminum design assures that all sections are exactly the same
and totally interchangeable. They come in 8'4", 4'4" and 2'4" lengths, so you can mix and match the length
you need up to 65 ft (20 m) for gas models and 65 ft (20 m) for air models.
The gasoline engine driven SCREED gives you a maximum eccentric speed of 2800 rpm, and permits idling of
the SCREED without stopping the engine. The air driven version gives you cycle vibration ranging from 5000
to 8000 VPM at 40 psi to 60 psi using about 4 CFM per vibrator.
The gasoline engine driven SCREED has winch kits available. The hand winch kit and the hydraulic winch kit.
The air powered SCREED offers the same fine features as our mechanical unit. It comes with optional handles
and an air system that includes filter, regulator and lubricator. It features an air line that is protected from damĆ
age by running inside the length of the AĆframe structure, and has flexible hose couplings between the air supĆ
ply tubes.
MBW Inc. has invested a great deal of time and effort in developing its SCREED. The equipment you have
purchased is built with a great deal of pride and designed to give you long life, efficient operation, durability and
dependability.

so could result in personal injury or equipment damage.
Major points of safe operation are detailed on the SAFETY PRECAUTIONS page of this manual. The SAFETY
PRECAUTIONS page is located on page 1.

SECTION ASSEMBLY
GENERAL
The following describes the assembly procedure of screed sections for both Mechanical
and Air Screeds. Most figures shown are of a Mechanical Screed. Section assembly of an
Air Screed is identical except where otherwise stated. It is essential to follow the proper
set-up sequence when assembling the screed for optimum performance.
IMPORTANT!
For steps 1-10, the screed sections
must be on a flat surface.
1. Determine the number of sections reĆ
quired to obtained the proper screed
length. Arrange the sections so the lonĆ
ger sections are in the middle and the
shorter sections are at the ends.
2. For the mechanical screed affix an enĆ
gine kit to one of the end sections or to
the middle section. Refer to Engine
Assembly for engine kit installation.
3. If an air screed is being used, refer to
Air Drive Assembly for instruction on
assembling air drive and end frames.
4. Assemble end frames and winches to
the end sections. Refer to End Frame
Assembly for installation of end
frames.
FIGURE 2
For the air screed join the threaded
manifold ends with a manifold hose.
Use a pipe wrench to prevent the manĆ
ifold from turning while the hose ends
are tightened onto the manifold ends
(see Figure 3). Assemble all sections in
this manner. Sight down top tubes of all
sections joined and straighten sections
if necessary.
5. Start assembling sections at one end of
the screed. For mechanical screeds
place a flex coupling along with two flex
coupling collars between the two couĆ
pling drivers of adjoining sections. ColĆ
lars should be slid out to the ends of the
flex coupling (see Figure 2).
IMPORTANT !
Check that the two vibrating shaft
offsets are in line.
Assemble all sections in this manner.
Sight down top tubes of all sections
joined and straighten sections if necesĆ
sary.

edging. Install a four hole splice plate
on the outside of edging and loosely
install four blind nuts (see Figures 4 and
5).

8. Make sure the bottom of the four edgĆ
ings are in the same plane. Tighten
both splice plates hard.
9. Take a right turnbuckle eye and install a
right-hand jam nut about three quarĆ
ters of the way up the shaft. Now install
the eye onto the turnbuckle a little over
half way. Do the same with the left turnĆ
buckle eye (see Figure 8).

7. Install a four bolt splice plate thru the
strikeoff edging. Install a four hole
splice plate on the inside of the edging
and loosely install 4 blind nuts (see FigĆ
ures 6 and 7).

10.Loosely install the turnbuckle assembly
directly above the flex coupling to both
clevises using a 5/8-18 X 2-1/2 bolt,
lockwasher, and a hex nut (see Figure
9). Install all the turnbuckles in the
same direction as you progress
down the screed. There is a notch cut
on one end of the turnbuckle to indicate
its direction. Remember, do not tighten
the turnbuckle hardware yet.

REPEAT STEPS 6 - 10 UNTIL ENTIRE SCREED IS ASSEMBLED.
After all needed sections are assembled
the edging can be trued horizontally.
11.If the pour surface is to be crowned or
flat, rotate the turnbuckles so the turnĆ
buckle eyes are pushed away from
each other taking out the slack at the
clevis connections. If the pour surface
is a valley, rotate the turnbuckles so the
turnbuckle eyes are drawn towards
each other taking out the slack at the
clevis connections (see Figure 10).
Tighten down the 5/8 bolts going
through the clevises and turnbuckle
eyes HARD once the slack is removed.

12. The screed is now ready for grade adĆ
justment. Place the assembled screed
on blocks or forms. String a taut chalk
line across the back of the float edge of
the screed (see Figure 11). Start with
the centermost turnbuckle and adjust it
so the bottom edge of the screed
moves up or down until it is adjusted to
the desired grade (see Figure 12). AdĆ
just each turnbuckle, working out from
the center, until the desired grade is
achieved. As the turnbuckles are adĆ
justed from the center out, previously
adjusted turnbuckles may need to be
readjusted to grade. Readjust the cenĆ
termost turnbuckles and continue adĆ
justing outward. When all adjustments
are completed, hold the turnbuckle
from further movement and tighten the
jam nuts.
FIGURE 12
CAUTION!
If there is a significant difference beĆ
tween the ambient temperature at set up
and the temperature of the concrete to
be screeded, the edgings may warp due
to thermal expansion. Recheck the
grade of the screed if this is the case.

ENGINE ASSEMBLY
GENERAL
The engine can be put on any mechanical screed section on the left end where there are
bearings in two adjacent A-frames.
1. To install sheave, first remove left couĆ
pling driver. Support end of shaft when
driving out the spiral pin. Now remove
left end A-frame and clevis. Slide
#09126 sheave onto main shaft. Also
put both V-belts, supplied with engine
kit, around main shaft and over top of
the top tube (see Figure 13). ReassemĆ
ble left A-frame, clevis and coupling
driver (see Figure 14). Do not install the
top tube bolts at this time.
FIGURE 13
ing bracket thru holes aligned above
(See Figure 15). These bolts replace
the original 3/8-16 X 2 bolts that were
removed earlier.
FIGURE 15
3. Place engine mounting deck (#09787)
on top of mounting bracket installed in
Step 2. Loosely install engine mountĆ
ing deck using four whiz-lock bolts
and flange nuts thru slots in mounting
deck and thru holes in mounting brackĆ
et (see Figure 16). The mounting deck
should be in its lowest position.
FIGURE 14
2. Remove the two top tube bolts from
right A-frame next to left A-frame reĆ
moved in Step 1. Set #09090 mounting
bracket on top tube and align holes up
over the two A-frames. Use four
3/8-16 X 2-1/2 bolts to secure mountĆ
FIGURE 16
4. Bolt engine tight to the mounting deck
using four engine mounting bolts,
washers and flange nuts (see Figure
17).

FIGURE 17
5. Slip one V-belt over engine clutch.
Place V-belt on sheave and align
sheave with engine clutch. Secure
spare V-belt to an A-frame using tie
wraps (see Figure 18).
7. Adjust belt tension by sliding engine
mounting deck upward in slots. Check
belt tension by pinching belt between
your fingers.
Single Belt - The two sides of the belt
should touch or go slightly past each
other (see Figure 19).
Dual Belt - A 2" gap should remain beĆ
tween the two sides of both belts.
Tighten the four whiz-lock bolts holding
the engine mounting deck to the
mounting bracket. NOTE: Do not over
tighten belt.
FIGURE 18
Make sure the shaft is rotated to its
lowest position at this time. (set
screws in bearings are up).
6. Rotate pulley so the thick side of bore
is on top of the shaft. Tighten sheave
onto shaft by tightening the two screws
in the tapered bushing of sheave.
FIGURE 19
8. Bolt the belt guard to the mounting
bracket using three 5/16-18 X 1/2
screws (see Figure 20).
