SERIAL NUMBER LOCATION SCREED AND HYDRAULIC WINCH SERIAL NUMBERS The serial number for each screed section is located on the side of the left most A-Frame. The serial number is also stamped into the top of each A-Frame. SCREED FRAME HYDRAULIC WINCH SERIAL# (Stamped) SERIAL# DECAL PARTS ORDERING PROCEDURE The Warranty is stated in this book on page 7. Failure to return the Warranty Registration Card renders the Warranty null and void. PARTS ORDERING: MBW Inc.
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.
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). FIGURE 4 FIGURE 8 FIGURE 5 10.
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).
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. ing bracket thru holes aligned above (See Figure 15). These bolts replace the original 3/8-16 X 2 bolts that were removed earlier. 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.
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 17 5. Slip one V-belt over engine clutch.
END FRAME ASSEMBLY GENERAL The end frames are symmetrical and can be used on either end. NOTE: The end frames for the hydraulic drive are left hand and right hand. 1. Set an end frame on one of the screed ends and align the two bottom holes with the two holes in the edging. SeĆ cure with two 3/8-16 X 1 whiz-lock screws and two flange nuts (see Figure 21). 2. Attach eye bolt to clevis and place thru hole in center of cross brace.
HYDRAULIC DRIVE ASSEMBLY 4. Make sure the bottom of the four edgĆ ings are in the same plane. Securely tighten both splice plates. 1. Install end frames on either end of screed. 2. Install a three bolt splice plate on the inĆ side of the float edging. Install a four hole splice plate on the outside of the float edging and loosely install three blind nuts. (see Figure 23) 3. Install a four bolt splice plate on the outĆ side of the strikeoff edging.
OPERATING INSTRUCTIONS INTRODUCTION MBW Inc. Compaction Equipment is intended for use in very severe applications. They are powered by four cycle engines and are available in different sizes and a selection of engines. This parts manual contains only standard or standard option parts. Variations of these parts as well as other special parts are not included. Contact your local MBW, Inc. Distributor for assistance in identifying parts not included in this manuĆ al.
HYDRAULIC OIL SUPPLY - For Screeds with hydraulic winch kits, check to ensure there is an ample supply of Hydraulic Oil in the tank. DRIVE GEAR LEVER - For Screeds with hydraulic winch kits, check to enĆ sure lever is in the disengaged position, before starting the engine. STARTING 1. Open fuel valve. 2. Move choke control to the closed posiĆ tion. A warm engine may not need to be choked. DO NOT START OR RUN THIS MAĆ CHINE IN AN ENCLOSED AREA. THE ENGINE PRODUCES CARBON MONĆ OXIDE, A POISONOUS GAS.
4. Before starting up again, pick up screed and set it back about a foot, then proceed. 5. If there is a time delay between conĆ crete trucks, the unfinished concrete should be rough graded back and well below screed strike off height. This will prevent a cold joint when screed operaĆ tion is resumed. FIGURE 25 CLEANING 1. After using screed for the day, immediĆ ately wash the screed down with a waĆ ter hose or high pressure washer and scrub any hard buildup of concrete with a stiff brush.
SCREED MAINTENANCE & SERVICE A-FRAME REPLACEMENT Make sure offset of coupling driver matches offset of eccentric bearings when installed (thick side of couĆ pling driver matches orientation of thick side of eccentric bearings). Support end of shaft when driving the spiral pin through. The pin should be driven in so an equal amount of the pin is protruding from the coupling driver on either side. 12. If applicable, tighten drive pulley and align as described in ENGINE ASĆ SEMBLY. REMOVAL (Mechanical) 1.
BEARING REPLACEMENT (Mechanical Screed) 1. Remove A-frame (Refer to section on A-FRAME REPLACEMENT). 2. Knock out or press out old bearing out of A-frame. 3. Press new bearing into A-frame. 4. Install A-frame into screed (refer to AFRAME REPLACEMENT). DRIVE BELT REPLACEMENT (Mechanical Screed) GENERAL There should always be two drive belts on the screed. One for driving and one for emerĆ gency replacement. It is assumed the engine kit is installed on the left side of screed for this procedure. 1.
LONG STORAGE (Mechanical Screed) Before storing screed for an extended period of time: 1. Grease bearings with one shot of low temperature grease after final usage before storĆ ing. Run screed at operating speed for one minute after greasing all bearings. 2. Refer to engine's OPERATORS MANUAL for instructions on storage procedure for enĆ gine. CHANGE HYDRAULIC OIL (Hydraulic Winches) 1. Remove winch assembly from screed sections. 2.
BEARING LOCATIONS (MECHANICAL SCREED) The eccentric bearings are located in the screed A-frames as shown below.
AIR EXCITER & GROMMET LOCATIONS (AIR SCREED) Air exciters and grommets are located on the screed as shown below.
