PROBLEM

Show/hide table

The existing control mechanism for the propel pump may wear prematurely on certain CB22, CB24 XT, CB32, and CC24 Utility Compactors. If the existing control mechanism wears it may result in reduced propel performance due to an inability to maintain pressures required from the propel pump for some applications. This condition is usually present in one direction only but may also be exhibited in both directions.

The most likely symptom is the machine will come to a rest when encountering terrain which increases the power required to propel, such as a high grade or rolling a surface with a very high rolling resistance.
