STEP 3: Pre-load spring one flat (1/6 turn) at a time on hex shaft

and replace. When desired pre-load is reached, secure
pivot connectors to spring shafts with set screws.

Recommended pre-loads:
Single axle kits - Start by turning two flats (1/3 turn) of pre-load,
adding more if needed. For containers up to 22', start by turning
three flats (1/2 turn) of pre-load.
Tandem/multi-axle kits - One flat (1/6 turn) of pre-load can be
added, but do not exceed that amount or spring may be dam-
aged. Tandem/multi-axle kits require less pre-load because
spring loads up more quickly.
Trailers - Start by turning three flats (1/2 turn) of pre-load and
increase as needed.
