MAINTENANCE

Checking and Replacing the V-Belt and Clutch

1.After 200 hours of operation, remove the belt cover to check the V-belt tension (Figure 30). Tension is proper if the belt bends about 3/8”(10 mm) when depressed strongly with finger between shafts.Loose or wornV-belts reduces power transmission efficiency, causing weak compaction and reduces the life of the belt itself.

Figure 30. V-Belt Check

Replacing the V-belt

Remove the belt cover. Engage an offset wrench 3/4”(19 mm) or the like to vibrator pulley (lower) fastening bolt. Engage waste cloth or the like at midway of V-belt on the left side and while pulling it back strongly, rotate the offset wrench clockwise so that the V-belt will come off.

Reinstalling the V-belt

Engage V-belt to lower vibrator pulley and push the V-belt to left side of upper clutch and, in the same manner as in removal, rotate offset wrench clockwise so that the V-belt goes back on.

Checking Clutch

Check the clutch simultaneously with V-belt checking. With belt cover removed, check outer drum of the clutch for seizure and "V" groove for wear or damage with your eyes. Clean the "V" groove as necessary. Wear of lining or shoe should be checked with running check. If the shoe is worn, power transmission becomes deficient and slipping will result.

Replacing Clutch

Remove V-belt. Remove bolt at engine power output by giving a shock to an engaged wrench (tapping with hammer or the like)and rotating bolt counterclockwise. Remove clutch with a pulley extractor.To reinstall, reverse the procedure.

CAUTION

Whenever the compactor's vibration becomes weak or lost during normal operation regardless of operation hours, check theV-belt and clutch immediately.

Vibrator Oil Level Check

NOTICE

Alwayscleantheareaaroundthevibratoroillevelcheckplug before removing oil check plug. This will prevent dirt and debris from entering the system.

1.In every 100 hours of operation, with the machine positioned horizontally, use a 3/4” (19 mm) wrench and remove vibrator oil level check plug (Figure 31).Visually inspect and see if vibrator oil level is up to filler port. Be sure to clean area around check hole to prevent dirt and dust from entering.

DrainingVibrator Oil

1.Replace vibrator oil after first 200 hours and in every 1,000 hours of operation.

2.Position handle bar vertically (storage position).

3.Using a 14 mm wrench remove the vibrator oil drain plug (Figure 31) from the vibrating plate assembly.

NOTICE

For draining oil through level check hole, have the machine inclined with a sleeper or the like placed under the compaction plate on opposite side.

4.After vibrator oil has been completely drained from machine, fill with 10W-30 motor oil to the appropriate safe operating level (Figure 31).

5.Reinstall drain plug into vibrating plate assembly.Apply seal tape or Loctite #575 to thread portion of drain plug.

Draining Hydraulic Oil

1.Disconnect the hydraulic hose connected to the hydraulic oil cylinder (Figure 32).

MVH306GH specifications

The Multiquip MVH306GH is a versatile, heavy-duty vibratory plate compactor designed for a variety of soil and asphalt compaction applications in construction and landscaping. This powerful machine is built to deliver optimal performance while ensuring operator comfort and ease of use.

One of the main features of the MVH306GH is its robust Honda GX160 engine, which provides reliable power and high efficiency. The engine generates sufficient force to achieve deep compaction in different soil types, including clay, sand, and gravel. With its ability to produce 3,600 vibrations per minute, the MVH306GH ensures that the compaction is uniform, reducing the likelihood of future settlement in the compacted material.

Another noteworthy feature of the MVH306GH is its durable construction. The compactor is constructed with a heavy-duty steel plate that can withstand the rigors of daily use on construction sites. Its high-quality build guarantees longevity and reduces the need for frequent maintenance. The unit is also equipped with a foldable handle, which enhances its portability and storage, especially in tight spaces.

Comfort and usability are paramount in the design of the MVH306GH. The machine features an ergonomic vibration-dampened handle that minimizes operator fatigue during prolonged use. This design consideration allows operators to work efficiently without experiencing discomfort, leading to increased productivity on the job site.

The MVH306GH is also equipped with a reliable water tank, allowing for the added benefit of wet compaction, which is essential when working on asphalt. The ability to use water helps to bond materials together, resulting in a more stable and durable surface.

In terms of technology, the MVH306GH features an advanced vibration system that optimizes the compactor's performance. This system helps in achieving maximum compaction density while minimizing the likelihood of over-compaction that can lead to future cracking or damage.

Overall, the Multiquip MVH306GH vibratory plate compactor is an ideal choice for contractors looking for a powerful, efficient, and user-friendly solution for their compaction needs. With its impressive features, durable construction, and thoughtful design, this machine proves to be a valuable asset in any construction or landscaping project.
