Threadlockers, Studs and Carburetor Installation
Studs are often used for accurate positioning of auto parts, such as carburetors, water pumps, and manifolds to make the assembly job just a little easier. Studs assure that carburetors stay perfectly sealed to the intake manifold, and aligned with the gasket or sealing surface to help the assembly remain resistant to loosening from vibration and eventually leaking or sucking air.
Studs come in different heights and lengths, to accommodate different combinations of carburetor and spacer. By using threadlockers (such as Loctite Blue Threadlocker 243) to install these studs, you know they are being installed at the correct position for proper installation of the carburetor or whatever component is being assembled.
Here you see positioned studs holding the carburetor:
And here studs are being used on the water pump and pulley system on the front of the engine. This was a critical application, as the studs had to be positioned at the right distance to properly hold the water pump and attach the additional bracketry for the power steering pump/reservoir, alternator, and belt tensioner.
Threadlockers are also beneficial in front drive system installation, like this one on my Chevelle motor. The assembly instructions from the manufacturer, Concept1, specify the use of Loctite threadlockers.
In addition to studs, Loctite 243 Threadlocker can also be used for such applications as oil pans, disc brake calipers, pulley assemblies and many more.
