MAINTENANCE
Replacing the Leaves
Match mark external and internal leaves to body before removing to ensure they are
reinstalled in their original positions. This will help maintain balance and expanded diameter
as manufactured.
If using
Loctite
:
Use
Loctite 222
on fasteners smaller than 1/4".
Use
Loctite 242
on larger sizes.
External Leaves
1. Inflate the shaft enough to lift the external leaves. This prevents collapse of the internal leaves.
2. Remove all fasteners from external leaves. (Leaves were installed using
Loctite 242
; you may
need to use heat or an impact wrench to break the seal.)
3. Align the new leaves on the shaft.
4. Use the new fasteners supplied with your shaft to install the external leaves. (Note: If the new
fasteners do not have a pre-applied threadlocker, use a small amount of
Loctite
on the threads.)
Install the screws in the leaves and tighten.
5. Deflate the shaft completely.
Internal Leaves
1. Remove the rubber tube assembly from the shaft (p. 9).
2. Remove one external leaf at a time and pull out the matching internal leaf until all leaves are
removed. (If leaves were installed using
Loctite 242
; you may need to use heat or an impact
wrench to break the seal.)
3. Use the new fasteners supplied with your shaft to install the external leaves. (Note: If the new
fasteners do not have a pre-applied threadlocker, use a small amount of
Loctite
on the threads.)
Reinstall one internal leaf and its matching external leaf, one at a time, until all leaves are
reinstalled.
4. Tighten all fasteners.
5. Reinstall the rubber tube assembly (p. 10). If necessary, lift the external leaves and wedge them
open to ease insertion of the rubber tube.
Replacing Springs
Tidland no longer supplies the steel springs; you can replace them with Poron® microcellular urethane
(foam-like) springs for the same results.
Note that slots must be at least .25-inch wide for standard Poron spring Tidland part number 564892.
For leaf sets that have narrower slots than .25 inch, call Tidland for assistance.
1. Remove internal leaves.
2. Remove springs:
Steel springs:
Remove all steel springs from leaf set. Grind or file edges of slots where steel
springs were crimped to remove sharp edges.
Poron
®
(foam) springs:
Remove all of the spring material from the slot.
3. Clean slots with isopropyl alcohol (rubbing alcohol) to remove any contamination; let dry.
4. Remove adhesive liner from back of Poron springs and place the spring into the slot, adhesive
side down. Press the spring in place.
5. Place one Poron spring at every other space between buttons for button or leaf shafts.
6. Reassemble the leaf shaft.
