Product Overview
The 220310-B is a heavy-duty shear-type rubber engine mount built for 5-ton class wheel loaders and comparable heavy construction equipment. It sits between the powertrain (engine or transmission assembly) and the machine frame, working as the core vibration damping component for the entire power system.
Diesel engines produce steady vibration at idle, and loading/dumping cycles add sudden impact shock during daily operation. This mount absorbs these forces before they transfer to the main chassis, slowing down structural fatigue, preventing fasteners from loosening, and reducing wear on sensitive hydraulic valves and electrical parts. It also cuts down structure-borne noise inside the operator cabin for better working comfort.
Build & Material
This mount uses a fully embedded high-strength steel skeleton, bonded to premium natural rubber through a high-temperature vulcanization process. This molecular-level bond eliminates delamination between rubber and metal, even under extreme load and chassis twist on uneven job sites.
Both side mounting flanges (with bolt holes) and the center threaded insert are machined to match original equipment dimensions, making it a direct drop-in replacement with no modification needed. The rubber compound is formulated specifically for off-highway applications, with solid resistance to engine oil, hydraulic fluid, ozone and wide temperature swings.
Core Performance
Absorbs both high-frequency idle vibration and low-frequency working impact effectively
High vertical load capacity and stable lateral support for heavy powertrain assemblies
Withstands oil exposure and weathering for long service life in harsh site conditions
Maintains proper powertrain and driveshaft alignment under all operating loads
Full interchangeability with original equipment mounting points
Compatibility Scope
The 220310-B mount is primarily fitted on 5-ton wheel loaders from major Chinese construction machinery brands, including XCMG ZL50G / LW500K series, Shantui SL50W, Liugong CLG855 and Lonking LG855. It can also be used on other similar heavy equipment such as small bulldozers and backhoe loaders, as long as the mounting footprint matches.
