The Multiquip 511836 Fill Lock Bolt is a genuine OEM component designed for MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP series trash pumps. As a direct OEM replacement, this bolt is manufactured to the exact specifications Multiquip requires for proper sealing and retention at the fill point. Sourcing the correct hardware for fluid-handling equipment ensures the fill port stays secured under the vibration and stress of continuous pump operation.
Key Features
- Genuine OEM Hardware Spec: — Manufactured to Multiquip's exact thread pitch, grade, and dimensional tolerances required for fill port retention on MQ600 series trash pumps.
- Direct Drop-In Replacement: — Installs in the same position and orientation as the original, with no reworking of the fill port or surrounding components needed.
- Broad MQ600 Series Compatibility: — Confirmed fit across MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP trash pump models.
- Maintains Fill Port Integrity: — A properly torqued fill lock bolt keeps the fill port sealed against leaks and contamination during high-vibration pump operation; a missing or damaged bolt risks fluid loss and pump damage.
- Fluid System Safety: — Correct retention hardware at the fill point prevents unintended fluid release, protecting both the operator and the surrounding work area during pump operation.
The fill lock bolt secures the fill port cap or plug on the pump housing, keeping the oil or fluid cavity sealed during operation. Without a properly functioning fill lock bolt, the fill port can work loose under engine and pump vibration, leading to fluid leaks, contamination ingress, and potential seizure of internal pump components. Replacing a worn, stripped, or missing fill lock bolt promptly is a simple step that protects the longevity of the entire pump assembly.
