Multiquip 12308H1000 Wash Pulley Bolt

The Multiquip 12308H1000 Wash Pulley Bolt is a genuine OEM component designed for C30HDNI and C30HDN series concrete pumps, including C30HDNI Precision and C30HDNI Zenith variants. As a direct OEM replacement, this bolt is manufactured to the exact material and dimensional specifications required by Multiquip's Mayco concrete pump line. Sourced directly through an authorized Multiquip dealer, the 12308H1000 ensures correct installation without the guesswork of cross-referencing aftermarket alternatives. If your C30HDNI or C30HDN is due for wash system service, this is the right part for the job.

Key Features

• Genuine OEM Specification: — Manufactured to Multiquip's exact thread pitch, grade, and dimensional tolerances required for the wash pulley assembly — no substitution needed.
• Direct-Install Replacement: — Designed to seat and torque into the existing wash pulley mounting position on compatible Mayco concrete pump models without rework.
• Broad Fitment Across C30HD Variants: — Confirmed compatible with C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDN concrete pump models.
• Wash System Integrity: — A correctly torqued wash pulley bolt keeps the wash box drive assembly properly secured, ensuring consistent wash cycle operation and preventing premature pulley wear.
• Authorized Dealer Sourcing: — Sold by DHS Equipment, an authorized Multiquip dealer, so the part number, revision level, and OEM packaging are verified at the point of sale.

The wash pulley bolt secures the pulley within the wash box drive system of a concrete pump. The wash box assembly uses water to lubricate and clean the pistons and cylinders during operation, and the pulley is a key component in driving that system. If this bolt loosens, backs out, or fails, the wash pulley can shift or disengage, leading to inadequate lubrication of the pump cylinders and accelerated wear on the pistons and wear plates. Keeping this fastener in good condition is a straightforward but important part of routine concrete pump maintenance.
