The shaft of a caster which is part of the locking mechanism must be oriented correctly,
otherwise the caster will not lock when the brake pedal is activated.
13.1. Perform the following steps to correctly orient the caster shaft before finalizing the
replacement caster installation:
•
Ensure the new caster shaft mechanism is in the neutral position (brake/steer
pedal horizontal). To do so, insert the locking axle (
E
) in the new caster shaft
orifice and rotate the locking axle using a 7/16" wrench to identify the three
possible positions of the shaft mechanism: 5th wheel engaged, neutral, brake
engaged. Set the mechanism to the neutral position (middle position). Once
done, remove the locking axle from the caster shaft.
•
Insert the caster shaft into the mounting socket (
J
) and insert the locking axle (
E
)
completely. Replace the locking lever (
G
) on the locking axle (make sure the
pedal is in the neutral position before replacing the locking lever on the locking
axle), but not completely so as to have enough room between the mounting
socket (
J
) and the locking lever to insert a 7/16" wrench.
•
Using the 7/16" open wrench, rotate the locking axle while observing the pedal
movements created by the rotation of the axle, it will occupy three positions:
o
Green side of the pedal depressed: 5th wheel engaged.
o
Pedal in horizontal position: neutral position.
o
Red side of the pedal depressed: locking system engaged.
•
When the pedal red side is depressed, verify if the caster locks.
If the caster does not lock, the shaft is incorrectly oriented.
•
Remove the locking lever (
G
) from the locking axle and the locking axle (
E
) while
supporting the caster. Remove the caster and rotate its shaft 180°. Replace the
caster shaft into the mounting socket and replace the locking axle and locking
lever as previously described. Rotate again the axle while observing the pedals
movement created by the rotation of the axle.
•
This time, when the pedal red side depresses, the caster should lock. The caster
shaft is now correctly oriented and the replacement caster installation can now
be finalized. Do not forget to install the Rue ring (
D
).
14. Apply the brakes and ensure that the two casters (diagonally opposed) which are part of the
brake system are locked before returning the bed to service.
