The Multiquip 1901303450 Cylinder Head Bolt is a genuine OEM Cylinder Head Bolt designed for DAW-500S welders, DCA15SPX3, and DCA10SPX3 diesel-powered generators. As a direct OEM replacement, the part meets the original engineering specifications for thread pitch, tensile strength, and dimensional tolerances required in these applications. Sourced directly through the Multiquip OEM supply chain, this bolt ensures a correct, secure fit when reinstalling or servicing a cylinder head on compatible equipment. DHS Equipment stocks this part to keep your Multiquip welder or generator back in service without unnecessary delays.
Key Features
- OEM Tensile and Thread Specification — Manufactured to the exact thread pitch and torque-rated tensile strength required for correct cylinder head sealing on Multiquip engines.
- Drop-In Installation — Matches the original bolt geometry so it seats directly into the engine block's threaded bores without modification or rework.
- Confirmed Fitment — Verified for use on DAW-500S welder and DCA15SPX3 and DCA10SPX3 diesel generator models.
- Maintains Cylinder Head Integrity — A correctly torqued, properly spec'd head bolt holds the head gasket under consistent clamping load, preserving compression and preventing combustion gas or coolant leaks.
- Critical Safety Fastener — Cylinder head bolts are load-bearing structural fasteners; using the correct OEM part ensures the clamping force stays within the design parameters of the engine, protecting against head gasket failure or engine damage.
A cylinder head bolt is a high-strength fastener that clamps the cylinder head tightly against the engine block, compressing the head gasket to form a combustion-tight and fluid-tight seal. When torqued to specification, these bolts maintain consistent clamping load through repeated heating and cooling cycles — a requirement on equipment like generators and welders that run under sustained load. A stretched, corroded, or improperly spec'd head bolt can cause the head gasket to lose its seal, leading to compression loss, overheating, oil contamination, or internal coolant leaks that can result in serious engine damage if not caught early.
