3. Check that the new chamber is properly aligned:
■The gap between the fill guide and the chamber is
consistent and even. Check the gap when the
chamber is in the down position.
■The chamber slides freely. It does not rub or bump.
4. Tighten the button head screws securely.
CAUTION: Make sure the test chamber can slide
up and down freely without contacting the fill
guide.
Note: It is possible to install the test chamber crooked
enough that it will hit the fill guide when it raises.
Lightly tighten the test chamber screws, and then
lift the chamber to check for interference with the fill
guide. With the chamber lifted, look up through the
test chamber and center it around the fill guide. Then,
tighten the test chamber screws completely.
5. If you adjusted the load cell limit screw (in step 1), use
a 5/16 wrench and adjust the screw to have a 0.006 in.

6. Attach the limit switch sensor to the air cylinder,
aligning the band about 1 in. from the end of the air
cylinder as shown.
1.3 Adjust the Air Lines
1. From the Mac-valve side, remove the bottom gate air lines that were disconnected from the T fitting.
(See step 2 in 1.1 Remove the Test Chamber on page 5.)
2. Replace the removed air lines with the 20 in. air lines provided in the upgrade kit. Route the 20 in. air
lines through the two empty grommets on the left side of the bucket.
Note: The air lines go in the grommets on the opposite side of the GrainGage from the ones you just
removed.
Use a non-corrosive lubricant to get the 20 in. air lines through the rubber grommets.
