Refer to “Figure 7-29 Left Rail Springs and Spools”.

around their spools.
a. The spools slide out of their mounting slots. To reinstall the spools, assemble each of the spools by
wedging them into the rail with the plastic washers at either side of each spool, then slide all the
assembled spools into their mounting slots at the same time. Lubricate the spring spools by
placing a drop of Lubriplate where the spool hub seats in the slot.
Note: Replace all the buoyancy springs in an upright at the same.
