Oil Pump/Trans Dowel AMC Hollow Style

The Oil Pump/Trans Dowel AMC Hollow Style is a precision alignment component engineered for classic and vintage AMC engine builds. This hollow-style dowel pin serves as a critical locating tool during oil pump and transmission assembly, ensuring proper bore alignment and eliminating costly misalignment during initial startup. Mechanics and engine builders working with American Motors Corporation engines—particularly in restoration, performance, or rebuild applications—rely on this dowel to guarantee repeatable, accurate installation every time.

This DURA-BOND AD-148 dowel pin features a hollow design that reduces weight while maintaining structural integrity essential for precise positioning. The hollow construction allows for easier extraction during disassembly and reduces the risk of seizure common with solid dowels in vintage aluminum and iron castings. Measuring 2.65 x 0.7 x 2.85 inches with a featherweight specification of 0.02 lbs, the dowel is compact enough for tight engine bay clearances yet robust enough to withstand repeated assembly cycles without deformation or wear.

Engine builders, restoration shops, and DIY enthusiasts undertaking AMC engine work—from inline six-cylinder to V8 platforms—benefit most from this dowel's precision engineering. Whether you're performing a complete engine overhaul, upgrading an oil pump for increased flow, or aligning a transmission bell housing during initial assembly, this hollow-style dowel eliminates guesswork and prevents the catastrophic damage caused by misaligned fastener holes. Installation is straightforward: position the dowel in its designated bore before mating the oil pump and transmission assembly, then remove before final torquing to specification.
