Marcy SM-4033 is a heavily built, long-lasting smith machine home gym. The addition of an adjustable bench, preacher curl pad, arm pressers, lower pulley, adjustable cable pulleys, dip station, pull-up bar, etc makes it a complete home gym.

The dimensions of the product may seem a little too space-consuming at first, but it is worth giving up that much space for this machine as it practically eliminates the need for any other machine in your garage gym.

Build Quality

Marcy SM-4033 takes up about 6 by 7 feet of your garage gym floor space. It also needs a ceiling height of about 9 feet for full functionality.

It is not only huge in size but also is a heavy-weight machine. The frame is made using strong 3×3” 14-gauge steel tubing. It is coated with red and black corrosion-resistant paint for durability.

The base of the frame is wide enough to offer stability to the machine even under intense use. It can also be bolted to the floor for added safety.

The strong J-hooks of the squat rack are lined on all sides to protect the bar and reduce the noise. There is a heavy-duty spring at the bottom catcher for the smith bar to damp the pace and noise of the falling smith bar in case of the failed rep when you even fail to rack the bar at any of the 17 holes.

The guide rods for the smith bar and the sliding weight post are chrome plated for a smooth finish and corrosion resistance. The smith bar glides smoothly over the angled guide rods with help of linear bearings.

Assembly and Maintenance

As you might expect from any large and heavy machine, it is not that easy to assemble the Marcy SM-4033 smith machine. It comes in a completely dismantled form, you need to put each part together with adjustable wrenches and Allen keys.

The tools required for assembly are not included in the package. You would need to buy an Allen key set and adjustable wrenches to complete the assembly.

The parts are heavy and need to be held in place for bolting together, for that, you need someone else to work with you at the start of assembly at least till the frame is assembled. Once the frame is assembled, you can put other parts and the attachments together by yourself.

It might take about five hours to finish the assembly. Once done, you will have a platform for almost all your favorite exercises in your garage gym.

The machine does have some moving parts like a smith bar and sliding weight post. Thus it needs regular preventive maintenance to avoid a major breakdown. You need to keep the guide rods for the smith bar and sliding weight post free from dust. Clean it regularly and apply some lubricant on the guide rods and to the linear bearing for smooth movement. Other than this, the Marcy SM-4033 doesn’t need any periodic maintenance.
