The Multiquip 9991105120 Bearing Holder Nut C240/6BD1 is a genuine OEM component designed for the Multiquip C240 cycloidal-drive concrete pump. Sourced directly from Multiquip, this nut is manufactured to the exact specifications required to secure the bearing holder assembly within the pump drive system. If you are servicing or rebuilding a C240 unit, this is the correct OEM part to restore proper mechanical integrity to the drivetrain.
Key Features
- Genuine OEM Thread and Torque Specification — manufactured to the precise thread profile and dimensional tolerances required for secure bearing retention in the C240 drive assembly.
- Direct Installation Fit — replaces the original nut in the bearing holder assembly without alteration, seating correctly against the mating surfaces as designed.
- Confirmed C240 Fitment — verified for use on the Multiquip C240 cycloidal concrete pump; always cross-reference part number 9991105120 against your serial plate before ordering.
- Drivetrain Security — a properly torqued bearing holder nut keeps the bearing assembly locked in position under the cyclic loads of concrete pumping; a loose or worn nut can lead to bearing migration and accelerated drivetrain wear.
- Correct Hardware for Rebuild and Maintenance Work — using the OEM-specified nut during bearing replacement or drivetrain service ensures the assembly meets the original clamping load requirements.
The bearing holder nut is a fastener that clamps and retains the bearing holder in position within the pump's cycloidal drive system. It works alongside the bearing and its housing to maintain proper shaft alignment and absorb the rotational and axial forces generated during pump operation. When this nut loosens, backs off, or is replaced with an incorrect substitute, bearing load distribution is compromised, which can accelerate wear on surrounding components and ultimately affect pump output and reliability.
