( Brand: Gm ), ( Manufacturer Part Number: 3703530 ), ( Part Type: Engine Rod Bolt Motor )
The product in question is a set of connecting rod bolts, specifically model number 3703530, which were originally used in 1955 General Motors engines. These bolts have seen their fair share of use and time, resulting in a rusty appearance. Each bolt is designed to connect the piston to the crankshaft rod in the engine, playing a crucial role in the engine's operation.
The bolts are manufactured from high-strength steel, ensuring they can withstand the immense pressure and force generated by the engine's combustion process. Despite their rusty exterior, the inner threads and core of the bolts are likely still in good condition, thanks to the resilience of the steel material.
In terms of dimensions, the bolts are typically 6-inch long, with a thread diameter of 0.875 inches and a head diameter of 1.25 inches. They may also have a hex head for easy installation and removal using a socket wrench.
It's important to note that while the rust may not affect the functionality of the bolts in a running engine, it does present a visual concern and may indicate potential corrosion issues. Replacing these rusty bolts with new, corrosion-resistant alternatives can restore not only the engine's aesthetic appeal but also improve its overall performance and longevity.
In summary, these 1955 General Motors connecting rod bolts (model number 3703530) are rusty but still functional, made from high-strength steel, and play a vital role in the engine's operation. Replacing them with new corrosion-resistant bolts can enhance the engine's appearance and performance.
