Caterpillar Sandwich Mount - Part 227-0172

The 227-0172 is a sandwich mount (also known as shock mount, part 40-127) designed for Caterpillar soil compactors and vibratory rollers. Cross-reference part numbers include 143-4650. This mount uses a rubber-steel-rubber sandwich construction where rubber is vulcanized between steel plates, providing critical vibration isolation between the vibratory drum mechanism and the machine frame. Compatible with a wide range of CAT compactor models including CP-44, CP-54B, CP-64, CP-76, CS-56, CS-66B, CS-74, CS-76, CS-78B and the CB-334D/E paver series. Also fits CAT engines 3013 through C6.6. CAT compactors are standard equipment on US highway and road construction projects. HAMM Mount provides this aftermarket replacement at substantial savings versus OEM pricing.

Manufactured by HAMM Mount in our ISO 9001:2015 certified facility using advanced vulcanization technology and premium rubber compounds. Every unit undergoes multi-stage quality control including dimensional inspection, hardness verification, and load-deflection testing. Fire safety compliance per EN 45545-2 is verified for all railway applications.
