All SAE Grade 8 bolts or metric class 10.9 may only be retorqued after the initial eight hours break-in period, then must be replaced if retorquing is required again.

  • Page 41: Bolt Torque Guidelines

    1. Always replace bolts and nuts with the same size and class of fastener. Replacement fasteners can be ordered from the Stanley LaBounty Parts Department to ensure the correct part is used (refer to fi gure 5-2). Unless otherwise specifi ed, use class 10.9 metric hex head capscrews, class 10.9 metric fl at head capscrews, and class 12.9 metric socket head capscrews.

  • Page 43: Guide Blade Shimming And Rotation

    MSD 7R SHEARS GUIDE BLADE SHIMMING AND ROTATION The guide blade helps keep the shear blades in line and must be checked daily. See fi gure 5-3. 1. With the shear partially closed so the upper wear area is in contact with the guide blade, check the gap between the wear area on the upper and the guide blade.

  • Page 44: Blade Rotation

    MSD 7R SHEARS BLADE ROTATION New blades in proper adjustment will increase the cutting performance of the shear. Proper rotation of blades will provide optimum use and the most performance from the shear. Recommended blade rotation is after approximately 80 hours of use; depending on the material being processed, this interval may be extended.

  • Page 45: Blade Shimming

    MSD 7R SHEARS BLADE SHIMMING Blade rotating is recommended every 80 hours of shear usage in order to assure uniform wear so shimming is possible. After rotating the blades the fi nal time, there is a possibility there will be a slight gap between the upper and lower blades, and shimming of the lower blades may be necessary.

  • Page 46: General Build-Up And Hardsurfacing

    Never apply more than two layers of hardsurfacing. The quality and attention to detail in welding can signifi cantly affect the life of the shear. LaBounty strongly recommends that only certifi ed welders be used.
