Mandrel Spacer .500in

The Peterson Fluid Mandrel Spacer .500in (Part #05-0742) is a precision aluminum spacer engineered for crankshaft assembly applications requiring exact mandrel positioning. This 0.5-inch thick spacer fits 1-inch mandrels and is manufactured in natural aluminum, delivering the dimensional accuracy critical to engine building, rebuilding, and performance machine shop work where crank clearance and component alignment directly impact engine longevity and performance.

With a thickness of precisely 0.5 inches, this mandrel spacer controls axial spacing during crankshaft work, preventing bearing bore misalignment and ensuring proper journal clearance. The aluminum construction provides lightweight strength while resisting corrosion, and the natural finish accommodates both hot and cold assembly methods. Compact dimensions (2.95 x 0.6 x 3 inches) and minimal weight (0.05 lbs) make it easy to integrate into engine assembly fixtures and tooling setups without adding unwanted mass to the crank assembly during work.

This spacer is essential for machine shops, engine builders, and professional mechanics performing crankshaft service, balancing, and assembly operations. Whether setting up bearing bore clearance on a fresh rebuild, managing journal spacing during performance modifications, or maintaining OEM specifications during maintenance, the mandrel spacer ensures repeatable positioning and prevents costly rework. Peterson Fluid's precision manufacturing background supports applications where dimensional tolerance matters to engine function and durability.

Engine building demands precision-grade tooling and fixtures. A properly sized mandrel spacer reduces setup time, eliminates guesswork in crank positioning, and protects expensive engine blocks and crankshaft assemblies from misalignment errors that can lead to bearing wear or catastrophic failure.
