MSD SABER SERIES SHEARS
GUIDE BLADE SHIMMING AND ROTATION
The guide blade gap is another adjustment that keeps the shear blades in line and ensures the proper opera-
tion of the shear. This adjustment should be checked daily.
1. Close the shear until the Saber Tip on the upper shear begins to bypass the guide blade (see Figure 5-8 ).
Use a feeler gauge to check the gap and record it. Close the shear in steps and check the gap at different
spots along the Saber Tip surface.
2. Find the smallest gap along the Saber Tip and mark it. The gap at this spot should not exceed 0.030" (0.76
mm). If the gap is more than this, it will be necessary to shim the guide blade.
3. Guide blade shims are provided with a new shear. The shim kit includes four shims that are 0.024" (0.61
mm) thick and one that is 0.12" (3 mm) thick.
4. To determine the amount of shims to use, subtract the desired gap of 0.010" (0.25 mm) from the smallest
gap that was recorded earlier. See the example at the right side of this page.
•
If the guide blade is stuck in its seat, refer to the
Blade Removal procedure in this section.
•
If the shear has been operated for more than 80
hours since the last blade rotation, it is recommend-
ed that all blades be rotated at this time. Follow the
instructions on this page and the following pages.
Do not check gaps while the shear is in motion.
Stay clear when closing the shear or severe in-
jury could result.
Example:
Recorded Gaps:
0.035" (0.89mm)
0.040" (1.02 mm)
0.045" (1.14 mm)
Smallest Gap = 0.035"
Minus Desired Gap - 0.010"
Shim Amount = 0.025"
For this example, one of the 0.024" (0.61 mm) thick
shims would be used to achieve the desired guide
blade gap.
