The Multiquip EM255731 Cylinder Clevis 50 ST30 60 is a genuine OEM component designed for ST30 series swing tube concrete pumps. This clevis is a direct factory replacement, ensuring the correct geometry and load rating for the hydraulic cylinder linkage on which it is used. Verified against Multiquip OEM specifications, EM255731 is the correct part for ST30 equipment operators who need a dependable, like-for-like replacement.
Key Features
- Genuine OEM Structural Integrity — Manufactured to the exact load-bearing and dimensional tolerances required for concrete pump cylinder linkage duty, where stress concentrations and cyclic loading demand precision-forged or machined clevis geometry.
- Direct-Connect Replacement — Matches the original pin bore diameter, thread specification, and overall length of the factory clevis, allowing straightforward installation into the existing cylinder rod and linkage mount.
- ST30 Series Fitment — Confirmed for ST30 swing tube concrete pumps; cross-reference EM255731 against your machine's parts diagram before ordering to verify application.
- Sustained Pumping Force Transfer — A correctly fitted clevis transmits full cylinder stroke force without play or binding, maintaining consistent concrete output pressure and protecting the cylinder rod from side-load damage.
- Wear-Related Failure Prevention — A worn or cracked clevis introduces slop into the linkage, accelerating pin bore elongation and cylinder seal wear; replacing with this part restores tight, controlled articulation.
A cylinder clevis is the mechanical link that connects the hydraulic cylinder rod to the pump's drive linkage or swing tube actuating arm. It transfers the linear push-pull force of the cylinder into the mechanical movement needed to drive concrete through the pump. When a clevis wears — through pin bore elongation, cracking, or thread damage — the connection becomes loose, causing erratic pump stroke, increased shock loading on surrounding components, and eventual loss of pumping performance or structural failure of the linkage assembly.
