Machinery Service & Design can manufacture any specialty tool you may need at an affordable price.

This socket tool is used on pistons with recessed nuts. The socket can be made to any size and/or configuration mounted to a standard plate that fits our Nut Buster®. These sockets are made to take the high torques our “Nut Buster” develops.

The through hole on our socket tools allows for clearance of the cushion extension found on some cylinders. With the MSD-CS socket tool the need for deep well sockets in the larger sizes is eliminated.

We can custom build to any size or configuration.

MSD-PAC | Pull Apart Cylinder

Our pull-apart cylinder (MSD-PAC) is used with two standard brace tooling assemblies (MSD-BT) and three slide plates (MSD-SP) on our Disassembly Fixture. The pull apart cylinder will reduce the effort involved in disassembling a large cylinder. It will also increase safety by eliminating the need to have several people pulling and jerking on a cylinder trying to get it apart.

MSD-SP | Slide Plates

The slide plates are predrilled for all our tooling options and are supplied with a set of “L” clamps.

MSD-LB | “L” Clamps

The “L” clamps are used to secure the slide plates, Nut Busters® and adjustable brace tools to the Disassembly Table.

MSD-VPS | Vacuum Pump System

The Machinery Service & Design vacuum system is used to assist the reassembly of hydraulic cylinders. This system takes advantage of atmospheric pressure to simplify the process of entering seals into the bore chamfer and retracting the shaft.

Our two-stage pump delivers high volume and produces vacuum up to 30” of mercury.

MSD-LP | Lock Pin

The MSD-LP lock pins are used to easily and quickly pin the slide plate in place to minimize movement during disassembly and assembly. They are sold in sets of two.
