Nut Buster® Hydraulic Torque Wrench | MSD-N-20/30/40/50NR/70NR/100NR
The honing head consists of a linear bearing slide with a vertical adjustment of 17 inches and a hydraulic drive motor that will accept any honing tooling.
The Nut Buster® is a hydraulically operated ratchet (hydraulic torque wrench) that removes or installs piston nuts and cylinder heads. It uses a minimum of 2 GPM and 3000 psi to develop 20,000 to 100,000 foot-pounds of torque.
The Nut Busters® is a hydraulically operated ratchet (hydraulic torque wrench). It is a nut removal tool used to remove or install piston nuts and cylinder heads. The Nut Buster uses a minimum of 2 GPM and 3000 psi to develop 20,000 to 100,000 foot-pounds of torque, depending upon the model. All models come standard with a rotating base (MSD-N-RB), pictured here.
The Nut Busters® uses a square 8” plate as the base for the sockets and attachments. The attachments slide into the adapter on either end of the Nut Busters® and rotate 45° to lock in place. Depending upon which side of the Nut Busters® is used the tool will rotate clockwise or counterclockwise. The Nut Busters® is designed to be used with the MSD–D Disassembly Table. It can also be adapted to fit your existing table. Please be sure to read and understand the operating instructions for the Nut Busters® before operating the tool.

Valve manifold directs oil to either the cylinders for high torque activation or to the drive motor for variable speed nut removal. Speed of rotation can be controlled when the drive motor is engaged.
A 5-to-1 mechanical advantage is accomplished with the use of no. 60 chain and sprocket assembly.
A high torque OMS 400 series “DanFoss” drive motor will deliver variable speeds at torques up to 2,500 ft/lb. This supplies enough torque for most jobs.
