Compactor Wacker Plate Frequently Asked Questons

The engine on the machine will not start or runs erratically, what is wrong with it?

It could be any number of reasons, which might include insufficient fuel, clogged air filter or damaged spark plug.

Why is compactor wacker plate engine speed and performance important for compaction?

Variation in engine speed and performance can have a significant effect on the exciter, which produces centrifugal force for compaction.

If a compactor wacker plate’s engine produces faster speeds than it is designed for, what may happen?

Apart from possible engine failure, bearings on the exciter may become overloaded by the increase in centrifugal force that will ultimately lead to failure of the bearings.

If a compactor wacker plate’s engine produces lower speeds than it is designed for, what may happen?

Slow travel speed and poor compactor performance may occur due to a low centrifugal force and possible engine failure.

VPM, what does this phrase mean?

VPM or Vibration Per Minute is the measurement of vibrations produced by a compactor wacker plate’s exciter.

The machine’s engine is running but there is no vibration, what is wrong?

The problem could be a worn centrifugal clutch or V-belt on the compactor wacker plate.

The compactor wacker plate exciter contains oil, how important is to have the correct amount of oil?

Failure of the machine’s exciter may arise if there is too much or too little oil within it.

Is it possible to use old fuel to run the machine’s engine?

It is advisable to always use fresh fuel. When the compactor wacker plate is not in use for considerable amount of time, it is advisable to drain the fuel tank to prevent ‘waxing’ of the fuel.

The machine pulls to one side when operating, what is wrong with it?

There could be numerous reasons for this. However, it could be simply due to warped or damaged shock mounts on the compactor wacker plate.

How may a worn base plate affect a machine?

Excess base plate wear may lead to a warped base plate. The consequential damage may also affect and damage the exciter, possibly leading to oil loss, and its securing bolts.

Whilst transporting a machine, it was accidentally dropped. Can it still be used?

For safety reasons, it would be advisable to have the compactor wacker plate inspected by a professional service dealer/repairer before use.

How long can a machine be used between service intervals?

Service intervals are dependant on make and model of the compactor wacker plate. Consult the operator’s handbook for further information or contact a professional dealer for advice.
