CHAPTER 12 STORAGE

Because a Mixer Feeder is year–round implement, it should be in ready–to–operate condition at all times. Several provisions have been designed into the Mixer Feeder to enable it to be used in cold, moderate and warm outside temperatures. The most important factor for continuous proper operation is lubrication. Routine lubrication should be repeated more frequently in both temperature extremes. If the trailer-type unit is stored outside, BE SURE to remove the Drain Plugs and adjust the Hitchjack to angle the unit to be lower in front, when the unit is NOT being used.

NOTE: When operating the Mixer Feeder in freezing temperatures, the unit should be stored inside, if possible.

Chapter 13 Troubleshooting

NOTE: This Troubleshooting guide presents problems, causes and suggested remedies beyond the extent of loose, worn or missing parts and it was developed with the understanding that the machine is in otherwise good operating condition. Refer to the index at the back of this manual for Chapter and Topic page references. BE SURE to exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8), BEFORE making any adjustments or repairs.

CHAPTER 14 SET-UP & ASSEMBLY

General Information

MF7000 Series Trailer-type Mixer Feeders are shipped in varying stages of disassembly, as well as with the optional One-Piece or Two-piece Discharge Conveyor NOT installed. This Set-up & Assembly chapter is divided into two sections; Standard Components and Accessory Components. The following procedures should be performed inside an enclosed workshop which is equipped with the proper tools and an overhead hoist. Although the procedures imply a single set-up person, two people can and will be able to assemble the components to the machine more quickly and easily.

NOTE: The following abbreviations are used herein:

CS-Cap Screw (Hexagon Head)

RHMS-Round Head Machine Screw

SHSS-Socket Head Set Screw

N-Nut (Hexagon)

LN-Lock Nut (Hexagon)

L-Lock (Washer)

P-Plain (Washer)

NPT-National Pipe Thread

Unless otherwise noted, the standard fastening procedure is to secure two parts with a CS, L and N. A part with a mounting slot should be secured with a P against the slotted surfaces. LN’s are sometimes used to prevent two parts from separating but still to allow one part to move or rotate next to the other. Attaching hardware, which will require installation in the path of material flow should always be installed with the head of the screw on the same side of part which will be in contact with the material.

Standard Components

Telescoping PTO Drive

Connect the Telescoping PTO Drive to the Mixer Feeder Drive Shaft making sure that the Shaft is clean and lightly greased before installing the Drive Yoke. Slide the Yoke all the way onto the Shaft and secure it with the Key and Set Screw and the CS and LN.

One-piece Discharge Conveyor (Fig. 28)

NOTE: If Mixer Feeder is going to be set-up with an accessory Single Valve Conversion package, those components should be installed first. The One-piece Discharge Conveyor is shipped in three component subassemblies; the One-piece Conveyor subassembly, the hydraulic Hoses and the completing parts package. Assemble the components of the Onepiece Conveyor to the Mixer Feeder, in the following manner:

1.Using an overhead hoist or other appropriate safe means of raising and supporting the Conveyor assembly, proceed to position and install the Conveyor assembly to the Discharge Door opening. When properly positioned, the top flange of the Conveyor assembly should be below the flange at the bottom of the Discharge Door opening and the Side Panels of the Conveyor should be to the inside of the Mounting Plate on each side of the Discharge Door. Attach the Conveyor Side Panels to the Mounting Plates with (3 each side) 3/8 x 1 CS, N and L. A pair of upper mounting holes are provided in each Mounting Plate to enable attaching the Conveyor assembly in either a 30° or a 40° position. BE SURE that the Conveyor is attached in the same upper mounting hole on both sides. If the 30° position is used, the middle holes will need to be reamed-out to pass a Cap Screw through them. Tightly secure the attaching hardware after all six Cap Screws are installed.

2.Install 90° Elbow Fittings into each of the Motor ports. Install the Check Valve into the Elbow Fitting in the right Motor port (as viewed from the Shaft end). Position both Elbow Fittings so they point away from the shaft of the Motor.

3.Properly position and install the Orbital Motor to the bottom Shaft of the Conveyor with the Shaft Coupler, a 1/4 x 1 Woodruff Key and (2) 5/16 x 5/16 SHSS. When properly positioned, the hydraulic Fittings on the Motor should be next to the Mixer Feeder Frame. Secure the Motor to the Motor Mount Bracket with (4 each) 3/8 x 1 CS & L. Then, tightly secure the (2) SHSS to secure the Motor to the Conveyor Shaft.

4.Route the Hydraulic Hoses as follows: a.For setting-up a unit for a standard hydraulics hookup, pass one end of each of the hydraulic Hoses through the Access Hole in the top of the Front Bearing Stand, over the Drawbar and through Hose Holder at the front lower left corner of Mixer Feeder Tank. b.For setting-up a unit for operation in conjunction with a Single Valve Conversion package, route each of the Hoses coming from the 3-Position Valve with Detent (on left side) over the Drawbar and through the Hose Holder at the front lower left corner of the Mixer Feeder Tank.

5.Connect one Hose to Elbow Fitting on the upper Motor port and connect the other Hose to the Check Valve on the lower Motor port. Install quick-disconnect couplers (purchased locally) to the tractor connection ends of the Hoses. Properly tighten all Hose and Fitting connections before test-running the unit.
