5.13 Checking and Adjusting Endshields
Plastic endshields are subject to expansion or contraction caused by large temperature variations. The position of
top pin and lower catch can be adjusted to compensate for dimensional changes.

Header Frame
1. Check gap (X) between front end of shields and header
frame and compare to values in Table 5.4, page 74.

Figure 5.41: Endshield Adjustment
2. Open endshield. Refer to 3.3 Opening Endshield, page
25.
3. Loosen nut (A) on pin (B) from inside endsheet.
4. Close endshield and adjust position to achieve desired
gap between front end of shield and header frame in
accordance with Table 5.4, page 74.
5. Open endshield and tighten nut (A).
6. Check for a snug fit between top of shield and header
frame, and for full engagement of endshield on pin (B).
7. If necessary, loosen bolts on catch (C) and adjust catch
as required to reposition shield.
