The Multiquip MQ21073 Liner Retaining Nut MT400CCEHD is a genuine OEM component designed for the MT400CCEHD rammer. Sourced directly from Multiquip, this part meets the exact specifications required to keep the liner assembly properly secured during operation. It is a direct replacement for the original hardware on MT400CCEHD tamper units, ensuring correct torque retention and liner stability. If you are servicing or rebuilding an MT400CCEHD rammer, verifying this part number against your machine's parts manual is always recommended before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original thread pitch and dimensional specifications, ensuring the nut seats and torques correctly against the liner assembly without distortion or backing off under vibration.
- Direct Replacement Hardware — Installs in place of the original retaining nut on the MT400CCEHD rammer with no modification to surrounding components required.
- MT400CCEHD Fitment — Confirmed for the Multiquip MT400CCEHD tamper; always cross-reference MQ21073 with your machine's parts manual to verify applicability.
- Maintains Liner Integrity Under Load — A correctly torqued liner retaining nut keeps the liner from shifting or loosening during the high-frequency impacts a rammer generates, protecting both the liner and the surrounding housing from premature wear.
- Critical Service Part — A loose or damaged retaining nut can allow the liner to move out of alignment, leading to accelerated wear on the liner bore and potentially causing mechanical failure during compaction work.
The liner retaining nut secures the liner within the rammer's lower housing assembly, holding it firmly in position so the piston can cycle through it repeatedly without causing liner movement or misalignment. Because rammers operate under continuous high-frequency impact forces, this nut must maintain its clamping load reliably over extended service periods. When the retaining nut becomes worn, stripped, or is not properly torqued, the liner can shift during operation, causing uneven wear, loss of compaction efficiency, and potential damage to the lower assembly that may require more extensive repairs.
