What’s an engine mount?

An engine mount supports an engine during repairs or rebuilding, and is made of high-grade iron or steel. Different types are required for different engine sizes and types, and proper engine mounting bolts must be used. Small engine mounts are versatile, but larger industrial equipment requires specific mounts.

An engine mount is a device used to support an engine after removal from a vehicle or prior to installation. It is primarily used to hold the block securely in place while a mechanic or engine builder breaks down, repairs, or rebuilds an engine. The stand is usually constructed of high-grade iron or steel, features rollers for easy portability in the engine shop, and rotates on a fixed axis to allow the engine builder easy access to each part of the engine while on the stand.

With the wide variety of different engines out there, there are almost as many types of engines on the market. A mount suitable for small car engines is not suitable for the larger engines required by trucks, trailers and heavy industrial equipment. Also, V-block engines sometimes require an engine mount that is designed differently than mounts suitable for inline engine blocks.

To connect a car or light truck engine to a proper engine mount, one must ensure that the bolts used are the proper engine mounting bolts. Engine mounting bolts are the proper thickness and length to ensure a secure fit between the engine and engine mount during repairs. You then need to orient the mounting arms on the engine mount, aligning the bolt holes in the mounting arms to the bolt holes in the engine block around the flywheel housing. This is where the engine would bolt to the bell housing for the transmission. The engine mounting bolts are inserted through the mounting arms, into the engine block, and must be tightened with a torque wrench to the specified torque rate for the particular engine.

Motor mounts for small engines tend to be versatile and are capable of handling a variety of different engine types. The main benefit of this is that a small to medium auto repair company does not have to invest in numerous types of engine mounts to service the various types of engines that come into the shop. Multipurpose engine mounts are suitable for most standard four-stroke engines, but rotary engines and motorcycle engines generally require different equipment.

For larger tractors and heavy industrial equipment, the factory recommended engine mount for that specific engine should be used. Generic multi-purpose engine mounts are not common in the industrial sector because proprietary designs are often coupled with fleet purchases. In many cases, a corporate or industrial contractor purchases an entire fleet of vehicles and equipment from the same manufacturer. As a result, multi-purpose support and repair kit that can be used for engines made by different manufacturers is not available.
