Compactor rubber mounts will eventually need to be replaced due to the hours of use or operator abuse. The mounts are designed to work in a temperature range of -18 to 70 ºC (0 to 160 ºF). Below -18 ºC (50 ºF), the rubber mounts become very stiff and not as effective in vibration dampening. Above 160 ºF ( 70 ºC), the rubber mount material becomes too soft and wears fast. Excessive down force on the compactor, overstretches the rubber and can lead to premature failure. Petroleum based products and solvent will degrade the rubber also.
Cracks may appear in the body of the rubber or where the rubber bonds to the metal plates. Light surface “cracking” due to age is acceptable. If cracks propagate into the body of the rubber, the mount must be replaced immediately. If the crack is located at the rubber to metal plate bond ( over 70mm long or 25mm deep ), the mount must be replaced.
When replaced, a pair, front or rear, need to be replaced at the same time.
