a. Remove the guide plates from the front of each grip pocket (use 6 mm hex key for 300DX frames,
or 10 mm hex key for 600DX frames).
b. Clean lubricant from all guide plates. This includes the guide plates on the rear of the grip
pocket; it is not necessary to remove them.
c. Inspect all guide plates for damage. Check for sharp edges, deformed corners and warping. Also
check all guide slots for damage - this could indicate a bent or broken guide pin (see step 6).
Sharp edges and deformed corners can typically be filed smooth. If damage is severe or inhibits
motion of the jaw carriers, the guide plates should be replaced.
5. For frames with G7-style crossheads: Clean and inspect wear plates:
a. Remove wear plates from each grip pocket.
b. Clean lubricant from the wear plates.
c. Inspect wear plates for damage. Check for broken plates, gouged or worn surfaces, bent edges,
and warping (see Figure 16 for an example of a damaged wear plate). If a wear plate has ANY
damage, replace it. It is very important that the wear plates be free from damage. If damaged
wear plates are used, damage to other grip components will occur!
d. It is highly recommended that the wear plates are replaced anytime the jaw carriers are replaced
(see step 6).
6. For frames with G7-style crossheads: Clean and inspect jaw carriers:
a. Remove jaw carriers from each grip pocket.
b. Clean lubricant from the jaw carriers.
c. Inspect jaw carriers for damage:
• Check the recess of each jaw carrier for dirt or damage. The locating boss of the grip jaw fits
into the recess with tight tolerance. Dirt or damage in either area may cause them to be
press-fit together during testing. If damage is found along the edge of the recess, the edge
can be filed smooth.
• Check for any cracks, particularly around the upper portion of the recess. If any cracks are
found, the jaw carrier must be replaced.
