3.8. Driveshaft
The installation procedure for the driveshaft and gearbox assembly on the EMD auger
depends on the size and length of the auger.
Because most of the driveshaft is pre-installed, consult Figure 3.6 before proceeding
with the assembly of your auger.
Since the length of the driveshaft determines the location of the gearbox, it is very
important that the length is correct for the corresponding auger.
Driveshafts on the 10” x 51’, 61’, and 71
’ augers require a square key. All other augers
use Woodruff (half-moon shaped) keys.
3.8.1. Procedure 1 - Driveshaft Addition
For all 6” and all 8” augers up to and including 51’, and the 71’ augers.
(For other
sizes, see Procedure 2 on the next page.)
For additional driveshaft segment(s), proceed as follows (see Figure 3.6):
1. Clean dirt and/or paint from driveshaft ends and from inside shaft connector(s).
2. Slide shaft connector halfway onto the last pre-installed driveshaft segment.
3. Slip the lower driveshaft segment through the bearings on the lower tube section.
Install a key and slide the shaft into the shaft connector.
4. Repeat for augers with two driveshaft additions.
Note:
A 16' 4" (4.98 m) driveshaft segment is strapped to the lower tube on the 8” x 71’ auger.
Do not use
. This auger requires a 19" (48.3 cm) addition only.
5. Tighten all set screws on shaft connectors.
6. Place a few drops of oil at each driveshaft bearing to allow for break-in.
Note:
The 6” x 61’ auger does not require driveshaft addition or removal. This auger requires
the removal of the first driveshaft bearing above the gearbox.
3.8.2. Procedure 2 - Driveshaft Removal
Includes 8” x 56’ and 61’ augers, and 10” x 31’, 41’, 51’, 61’, 71’ augers.
For removal of a driveshaft segment, proceed as follows (see Figure 3.6):
Note:
All required driveshafts are pre-installed and the lower driveshaft section is split.
Remove the segment nearest the intake end (as indicated in Figure 3.6), and remove
the shaft connector. The driveshaft length to be deleted is as follows:
• 8" x 56' - Remove driveshaft segment at 6' 4" (1.92 m)
• 8" x 61' - Remove driveshaft segment at 6' 4" (1.92 m)
• 10" x 31' - Remove driveshaft segment at 3' 10" (1.16 m)
• 10" x 41' - Remove driveshaft segment at 5' 2-1 /2” (1.58 m)
• 10" x 51' - Remove driveshaft segment at 9' 9" (2.97 m)
• 10" x 61' - Remove driveshaft segment at 6' 4" (1.92 m)
The 10” x 71’ auger requires:
