NOTE: The grass door torsion springs are mirror
image of each other. There is a left spring
and a right spring.
• The inner tail of each spring hooks through the
L-shaped hole in the grass door.
See Figure 4.13.
• The body of the spring fits into a recess in the
outboard edge of the grass door.
• The outer (L-shaped) tail of the spring hooks
over the top lip of the rear baffle when it is cor-
rectly installed. See Figure 4.14.
6. Position the rear grass door on the rear sub-frame.
7. Hook the ends of the left torsion springs over the lip
near the front edge of the rear sub-frame.
8. Press the door down to load the torsion springs.
9. Insert the hinge pin from the right-hand side.
See Figure 4.15.
• It should take roughly 15 lbs. (6 kg.) of force to
push the pin. If it is significantly looser, con-
sider replacing the complete rear subframe and
grass door assembly. See Figure 4.15.
• Push the hinge pin in far enough to expose the
small gap in the rear baffle.
