Replacement Procedures
Installation
1. Position the splined shaft so the alignment marks are at the bottom on
both tractors. (See page 535, Figure 122.)
2. Slide the splined shaft through the right side plate, tractors, and block
mounts. Make sure the same spline passes the marked groove on each
tractor. (See page 535 Figure 122.)
3. Install the tolerance ring on the left end of the splined shaft.
(See page 535, Figure 122.)
4. Insert the tolerance ring lead-in portion into the sealed ball bearing in the
left tractor shaft plate while sliding the ball bearing into the right side plate
(page 546, items 9, 10, 15, and 26). Push the splined shaft to the left until
the flange on the ball bearing is in solid contact with the right side plate.
The splined shaft will protrude about 1/16 inch (1.6mm) from the ball
bearing.
5. Install the right tractor shaft plate and screw (page 546, 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 tractor assembly support gates on the splined and support
shafts. (See installation instructions on page 537.)
7. Install the paper guide knobs and front paper guide leaves.
(See page 533, Figure 121.)
