SPACER INSTALLATION
("BLOCKING OUT" HYDRAULIC LIFT
SYSTEM UPPER LINK TENSION LOADS)
When grading and backfilling with light equipment,
such as a rear blade, the equipment may have a tendency
to "dive." If this condition is encountered, a spacer
(available from your Ford Tractor-Equipment Dealer)
can be installed between the draft control main spring
and spring seat to correct the condition. See Figure 97.
To install the spacer:
1. Loosen the tractor seat attaching nuts and push
the base of the seat forward.
2. Remove the pin that attaches the hydraulic lift
rocker to the yoke, Figure 97. Pull the rocker
back and unscrew the yoke.
