Shaft, Splined - IBM Infoprint 6500-v05 Maintenance Manual

Shaft, Splined

IMPORTANT
NOTE: In order to preserve correct alignment of the side plates, the barrier panel must remain installed and fastened
during this procedure.
Removal
1. Prepare the printer for maintenance (page 313).
2. Remove the static brush assembly.
3. Remove the paper supports from the splined shaft and support shaft. (See page 411, item 4.)
4. Remove the paper feed timing belt (page 317).
5. Unlock the left and right tractors and slide them to the center of the shaft.
6. Remove the screw securing the right tractor shaft plate and remove the plate (page 411, items 7 and 8).
7. Slide the splined shaft out of the sealed ball bearing in the left tractor shaft plate and remove the tolerance ring from the left
end of the splined shaft (page 411, items 3, 5, and 6).
8. Hold the tractors so they do not fall, grasp the vertical adjustment knob, and slide the splined shaft to the right, out of the
tractors and side plate.
Installation
1. Open the doors on the left and right tractors. Position the tractor belts so the alignment marks are at the top on both
tractors. (See Figure 23.)
2. Grasping the vertical adjustment knob, slide the splined shaft through the right side plate and tractors. Make sure the same
spline passes the marked groove on each tractor. (See Figure 23.)
3. Install the tolerance ring on the left end of the splined shaft (page 411, item 5).
4. Insert the tolerance ring lead-in portion into the sealed ball bearing in the left tractor shaft plate (page 411, items 3, 5, and
6) while sliding the ball bearing into the right side plate. Push the splined shaft to the left until the flange on the ball bearing
is in solid contact with right side plate. The splined shaft will protrude about 1/16 inch from the ball bearing.
5. Install the right tractor shaft plate and screw (page 411, items 7 and 8) by first sliding the upper "fingers" up and against the
flange on the ball bearing, then sliding the rectangular cutout over the support shaft end, then snapping the U-shaped
"spring" behind the tab on the right side plate.
6. Install the paper feed timing belt (page 317).
7. Set the paper feed timing belt tension (page 369).
