MC-92P/S CONCRETE MIXER — MAINTENANCE (MIXER)

Ball Socket and Clamp Face Maintenance

1.If the towing vechicle is equipped with a ball socket, smear socket periodically with multi-purpose grease. This will keep the ball socket well lubricated.

2.Periodically oil pivot points and clamp face surfaces of coupler with SAE 30 WT. motor oil.

2.Use Poleyrex EM (Exxon Mobil) or equalivant lubricant. Clean grease fitting, apply grease gun to fitting (1/2 shot). Remember too much grease or injecting grease too quickly can cause premature bearing failure. Slowly apply the recommended amount of grease, taking a miniute or so to apply.

3.When parking or storing your mixer. Keep the coupler off the ground so dirt will not build up in the ball socket.

Grease Fittings (Zerk) Maintenance (Mixer)

There are 3 grease (Figure 27) fittings that will require lubrication. Lubricate these fittings once a week. Use lithium base grease, grade N0.1.

Figure 27. Grease Fittings Mixer

Grease Fittings (Zerk) Maintenance (Electric Motor)

1.There are two grease (Figure 28) fittings at each end of the electric motor that will require lubrication. Lubricate these fittings about every 16 months.

Wheel Bearings

1.After every 3 months of operation, remove the hub dust cap and inspect the wheel bearings (Figure 29). Once a year, or when required, disassemble the wheel hubs remove the old grease and repack the bearings forcing grease between rollers, cone and cage with a good grade of high speed wheel bearing grease (never use grease heavier than 265 A.S.T.M. penetration (“No. 2.”)

Figure 29. Wheel Hub and Bearings

2.Fill the wheel hub (Figure 29) with grease to the inside diameter of the outer races and also fill the hub grease cap. Reassemble the hub and mount the wheel. Then tighten the adjusting nut, at the same time turn the wheel in both directions, until there is a slight bind to be sure all the bearing surfaces are in contact.

Then back-off the adjusting nut 1/6 to 1/4 turn or to the nearest locking hole or sufficiently to allow the wheel to rotate freely within limits of .001" to .010" end play.Lock the nut at this position. Install the cotter pin and dust cap, and tighten all hardware.

Mixer Cleaning

MC-92P, MC-92S specifications

The Multiquip MC-92S and MC-92P are high-performance concrete mixers designed for professional use in construction and masonry applications. These models offer a blend of power, durability, and user-friendly features, catering to the demands of contractors and construction workers who require reliable equipment for mixing concrete, mortar, and other materials.

The MC-92S is equipped with a robust 9.0 horsepower Honda gasoline engine that provides ample power for even the most demanding mixing tasks. This model features a 9 cubic feet capacity drum, allowing for larger batches of mixed material. The MC-92S is designed with a heavy-duty steel frame that enhances its durability and stability during operation. The drum is constructed with abrasion-resistant steel, ensuring longevity and minimizing wear over time.

In contrast, the MC-92P utilizes a powerful 9.0-horsepower propane engine, making it an excellent choice for users who prefer cleaner fuel options. This model retains many of the same design features as the MC-92S, including the enhanced drum capacity and rugged frame. The propane engine not only provides a quieter operation but also reduces emissions, making it a more environmentally friendly option without compromising performance.

One of the standout technologies in both models is the innovative mixing mechanism. The unique design of the mixing blades ensures efficient and consistent blending of materials, reducing the time required for mixing and enhancing the quality of the final product. Additionally, the MC-92 series features a manual dump system, which allows operators to easily and accurately discharge mixed material from the drum.

Safety is a primary concern in construction, and Multiquip has incorporated several safety features into these mixers. The control panel is designed for easy access and includes safety switches that prevent accidental start-up. The sturdy base and low center of gravity provide stability during operation, reducing the risk of tipping.

In summary, the Multiquip MC-92S and MC-92P concrete mixers are exceptional tools for professionals needing reliable, efficient, and versatile mixing equipment. With their powerful engines, capacity, durability, and innovative mixing technologies, they stand out in the competitive market of concrete mixers, ensuring that construction projects run smoothly and efficiently.
