ASSEMBLY INSTRUCTIONS CONTINUED:
32. ATTACHING GANG ASSEMBLIES - See Fig. 31.
NOTE: Find gang pattern for your disc on pages 41 to 52.
NOTE: Remove scraper assemblies and bundling tie bars from gang assemblies. The scraper assembly that is bundled with each gang will
be assembled together on the disc. Besure each gang and it’s scraper assembly is kept together. The 5/8" x 2" (15.7mm x 50.8mm)
U-bolts used to bundle scraper assemblies must be saved to assemble scraper bar to gang beam later.
a) USING GANG PATTERN FOR YOUR DISC - Identify the front and rear gangs. Next, determine which gangs are for R.H.S. and which are for L.H.S. For
solid hangers L.H and R.H. is determined by the 5/8" x 10" bearing retainer bolt. When the blades are correctly orientated the double nut end of the
5/8" x 10" (15.7mm x 254mm) bolt will face the rear of the disc, see Detail B. If your disc is equipped with stone flex hangers, L.H. and R.H. can also
be determined by the opening of the “C” shank. When blades are correctly orientated the open end of “C” shank will face the rear of disc, see Detail
A.
b) REAR GANGS - Roll rear gang assemblies in place under rear gang beams. The gang assemblies with outrigger blades (small diameter blades) must
be positioned at the outside. See Fig. 31 for the direction rear gangs face.
Attach bearing hangers to gang beams with (2) two 7/8" x 6" U-bolts per bearing hanger. Details “B” and “C” illustrates how to attach solid hangers.
Leave U-bolt loose. If disc is equipped with optional stone flex bearing hangers, see Step "D" to attach hangers.
c) FRONT GANGS - Roll front gang assemblies in place under front gang beams. See Fig. 31 for the direction the front gangs face.
Attach bearing hangers to gang beams with (2) two 7/8" x 6" U-bolts per bearing hanger. Details “B” and “C” illustrates how to attach solid hangers.
Leave U-bolts loose. If disc is equipped with optional stone flex bearing hangers, see Step "C" to attach hangers.
d) See Detail “A”, Fig. 31. If disc is equipped with optional stone flex bearing hangers, fasten each spring hanger assembly, arrow 1, to bottom of gang
beam, arrow 2, with one backing plate, arrow 3, and 2 U-bolts. Be sure dowel pin of backing plate, arrow 3, is installed in slot of spring shank.
e) See Fig. 31. Set front centre frame gangs, so that the leading edge of inside blades, arrow 4, are approximately 2-1/2" (63.5 mm) past centre of disc
frame - centre line of centre frame is shown in Fig. 31.
f) See Fig. 31. Set rear centre frame gangs, arrow 5, so that the distance between the rear edge of the two inside blades, dimension "D" is equal to 2"
(50.8 mm) less than diameter of blade to a maximum of 24" (610mm). For example, if your disc is equipped with 26" (660 mm) diameter blades,
dimension “D” would be set at 24"(610 mm). If your disc is equipped with 28" (711mm) or 30" (762mm) diameter blades, Dimension “D” would
be set at a maximum of 26" (660mm). Be sure rear gangs are centered.
g) See Fig. 31. Adjust blade to blade distance between individual gang assemblies. This distance should be the same as the blade spacing of your disc.
IMPORTANT: SPACE BETWEEN WING GANGS AND CENTRE FRAME GANGS MUST NOT BE LESS THAN BLADE SPACING. IF GANGS ARE SET TOO
CLOSE, THE TWO GANGS MAY INTERFERE WITH EACH OTHER WHEN WINGS ARE FOLDED.
h) Before tightening bearing hanger U-bolts, check each bearing hanger to make sure hanger is sitting square under gang beam. Next tighten U-bolts
to 430 ft. lbs. (583.0 N
.
m).
IMPORTANT: IF BEARING HANGERS ARE NOT SITTING SQUARE BEFORE TIGHTENING U-BOLTS, THRUST WILL BE BUILT INTO THE BEARINGS AND
THE LIFE OF THE BEARING WILL BE SHORTENED
33. ATTACHING SCRAPER ASSEMBLIES - See Fig. 31.
NOTE: Find gang pattern for your disc on pages 41 to 52.
a) Identify scraper assembly for each gang. As indicated in Section 32 above, the gangs were bundled with their corresponding scraper assembly.
Scraper assemblies are assembled L.H. and R.H. must be installed on appropriate side.
NOTE: Some gangs use a 90 degree scraper. Be sure the scraper assemblies with 90 degree scrapers are installed on the correct gangs.
