Plastic endshields a re subject to expansion or contraction from large temperature variations. The position of the
top pin and lower catch can be adjusted to compensate for dimensional changes.
To adjust the endshield, perform the following:
1. Check gap ‘X’ between the front end of shield and
header frame and compare to chart.

If adjustments are required, proceed as follows:
2. Open endshield. Refer to Opening Endshields, page
37.
3. From inside endsheet, loosen nut (A) on pin (B) with a
3/4 in. socket.
4. Close endshield and adjust position to achieve
the gap ‘X’ between the front end of shield and
header frame.
5. Open endshield and tighten nut (A).
6. To achieve a snug fit between top of shield and header
frame and to ensure that endshield is fully engaged on
pin (B), loosen bolts on catch (C) and adjust catch as
required to reposition shield.
7. Tighten bolts on catch (C).
8. Close endshield. Refer to Closing Endshields, page
