Multiquip EM20338 Spacer (Inboard Con Rod) - OEM Replacement Part for C30HD Concrete Pumps

The inboard connecting rod spacer maintains precise alignment and clearance between internal drive components in C30HD series concrete pumps, preventing metal-to-metal contact and ensuring smooth power transmission from the engine through the pump's drive system. This critical spacing component is part of the drive assembly that was water pressure tested at the factory under simulated full load conditions to verify proper clearances throughout the entire drive system and valving.

Located within the pump's internal drive mechanism, this spacer works in conjunction with the sprocket and pulley bushings that transfer power to the pumping valves. Proper spacing is essential for maintaining the torque specifications outlined in Multiquip service documentation, including the large sprocket bushing (55 lbf·ft), small sprocket bushing (16-20 lbf·ft), and large pulley bushing (30 lbf·ft) assemblies. Failure or wear of this spacer can result in misalignment, excessive vibration, premature bearing wear, or damage to connecting rod assemblies during high-pressure concrete pumping operations.

Compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
• C30HDZ
