Tongue Spacer Block
If the folded drill does not pull straight, wanders back and
forth while being towed, or fails to latch during folding, it
may be necessary to replace or adjust one or more
tongue spacer block assemblies.
Refer to Figure 58 (which depicts right tongue tube)
There are four of these block assemblies on the drill
tongue. Two
are on the inside, and contact each other
when folding. Two
are on the outside, and contact the
wing main frames when folded.
The amount of contact should be just enough to prevent
sway, but not so much that it prevents reliable transport
latching during fold.
If the skid blocks (
,
) are worn or deformed, replace
them.
If the skid blocks are serviceable, and there is a gap
when folded, add a shim
. Consult the latest Parts
manual for the current shim part number.
When re-installing:
• The inside blocks
must be exactly opposite each
other, and are located 122in (3.1m) from the forward
end of the tongue tube wall (dimension
).
• The outside blocks
are located 155in (3.74m) from
the forward end of the tongue tube wall (dimension
).
Note: It is normal for the tongue assembly to rotate slight-
ly when the wings move up and down independent-
ly. Adjusting tongue shims does not eliminate this.
