The Multiquip 1920203450 Cylinder Head Bolt is a genuine OEM component designed for D1402 and DCA-15SPX series equipment. Sourced directly from Multiquip, this bolt meets the exact specifications required to properly secure the cylinder head on compatible engines. It is a direct-fit replacement for D1402-powered machines, including the DCA-15SPX ultra-silent generator. Using the correct OEM hardware ensures proper clamping force and head gasket seating across the full service life of the engine.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the precise thread pitch, grade, and tensile strength required for cylinder head application — not a generic hardware substitute.
- Direct Installation Fit — Drops into the existing cylinder head bolt pattern on D1402 engines with no reworking of holes or hardware required.
- Confirmed Fitment — Compatible with D1402 and DCA-15SPX series Multiquip ultra-silent generators.
- Critical Sealing Function — Correct bolt torque and grade are essential to maintaining head gasket compression; the wrong fastener risks gasket failure, coolant or oil intrusion, and engine damage.
- Safety-Critical Hardware — Cylinder head bolts are a torque-sensitive, structurally critical fastener; using a genuine OEM part ensures the correct stretch and clamping load under operating pressure and temperature cycles.
A cylinder head bolt is a torque-critical fastener that clamps the cylinder head firmly against the engine block, compressing the head gasket to create an airtight and liquid-tight seal between the combustion chamber, coolant passages, and oil galleries. If a cylinder head bolt is under-torqued, stretched beyond its yield point, or replaced with an incorrect grade, the head gasket can fail — leading to coolant loss, oil contamination, compression loss, or catastrophic engine damage. Replacing worn or damaged cylinder head bolts with the correct OEM part, such as the Multiquip 1920203450, is essential to restoring proper engine integrity and preventing costly engine repairs on your DCA-15SPX generator.
