SHAFT INSTALLATION AND OPERATION

Standard Leaf Shaft

1. Install shaft as required for your machine application.

2. Slide the core onto the shaft.

3. Inflate rubber tube to 80-120 psi (5.5-8.3 bar) and begin winding.

Fixed Leaf Shaft

1. Install shaft as required for your machine application.

2. Rotate the shaft so that the fixed leaf is at the top; slide the core onto the shaft.

3. Inflate rubber tube to 80-120 psi (5.5-8.3 bar) and begin winding.

Positioning the fixed leaf at the top allows the internal rubber element to expand more

uniformly, and prevents the internal element from having to lift the weight of the material roll.

Inflating the shaft with the fixed leaf down or to the side can lead to

excessive element wear and premature failure.

Coreless Gripper Leaf Shaft

1. Install shaft as required for your machine

application.

2. Make sure shaft is completely deflated.

3. Make sure fixed leaf is in the correct position.

4. Lay web along the length of the shaft, sliding

it into the gap between the fixed leaf and the

gripper bar.

5. Inflate rubber tube to 80-120 psi (5.5-8.3 bar),

securing the web between the leaves.

6. Begin winding operation.

MAINTENANCE

Replacing a Valve

Shaft configurations vary. Valve may be installed in the end of the shaft or along its face.

1. Deflate the shaft. Remove all air.

2. Locate and remove the valve.

3. Apply thread sealant (according to manufacturer's directions) to the threads of the valve (unless

the sealant is pre-applied) and reinstall.

NOTE: Valves with pre-applied thread sealant are good for multiple uses. Always inspect the valve

threads for sufficient sealant; do not reuse more than six times.

4. Screw the valve into the shaft and torque to 8.8-10 ft·lbs (12-13.6 Nm).

Rubber Tube Fitting Designs

This is a brief overview of the the new clamp system and some common rubber tube assemblies. Please call

Maxcess if you have questions about your shaft assembly configuration.

If your replacement rubber tube assembly looks like this

==============================================>>>

=== then the shaft has a hole bored in the journal to accept the rubber tube

assembly with two o-rings as shown.

Remove your old rubber tube assembly (page 9) and install the new one,

pushing the tube assembly firmly into the socket in the journal.

See page 8 for using the hose clamp design with bulk rubber tube material.

If your replacement rubber tube assembly looks like this

==============================================>>>

=== then the shaft has a hole bored in the journal to accept the rubber tube

assembly with a male o-ring connector, pictured at right.

Remove your old rubber tube assembly (page 9) and install the new one,

pushing the tube assembly firmly into the socket in the journal.

See page 8 for using the hose clamp design with bulk rubber tube material.

If your replacement rubber tube assembly looks like this

==============================================>>>

===then it is directly interchangeable with older shaft designs. There are

fewer parts: rubber tube, tube fitting and hose clamp, pictured at right.

Remove your old rubber tube assembly (page 9) and install the new one,

pushing the tube assembly firmly onto the o-ring connector in the journal.

See page 8 for using the hose clamp design with bulk rubber tube material.

If your replacement rubber tube assembly looks like this

==============================================>>>

Remove your old rubber tube assembly (page 9) and install the new one,

pushing the tube assembly firmly onto the o-ring connector in the journal.

If you are using re-using your tube fittings with bulk rubber tube material,

see instructions starting on page 11.

MAINTENANCE

Using the hose clamp with bulk rubber tube material

Removing the hose clamp

Tidland recommends the use of a pincer for safe and easy removal of the hose clamp.

Standard pincer Tidland Part No. 27L778957

Spring return pincer Tidland Part No. 27L778958

1. With the pincer, squeeze the tangs (1) on the hose clamp until you can lift the load retaining hook (2),

and then release the pincer.

2. Remove the fittings and use them again with new rubber tube material. (Remember to reinstall the tube

stiffener, if needed.)

3. To close the clamp, squeeze the tangs until you can snap the load retaining hook into place.

MAINTENANCE

Assembly Rubber Tube Maintenance

Removing the Rubber Tube Assembly

Cantilevered shafts: Rubber tubes can be replaced without removing shaft from machine.

It is not necessary to remove the shaft leaves for rubber tube maintenance.

Pinch Hazard.

Keep fingers away from moving leaves.

1. If the tube will still hold air, inflate it enough to raise the shaft leaves; wedge the leaves in the

inflated position. This lifts the internal leaves off of the rubber tube assembly, allowing for

easier removal.

2. With the leaves wedged in lifted position, remove all air from the shaft. Use the Tidland Air

Release Tool for safety and best results.

3. For cantilevered shafts, remove the end cap and valve, if installed. Go to Step 8.

4. For shafts with journals, match mark the journal and body before removing the set screws; remove

the set screws.

5. Remove valve.

6. Using a round clamping fixture to protect the shaft body, lock the shaft in a vise.

7. Remove the journal: Attach the impact puller/slide-hammer to journal end and strike the weight

against stop.

8. Grasp rubber tube assembly firmly and pull from shaft.

9. Rubber tube fittings can now be disassembled and reused, if replacing only the tube material.

MAINTENANCE

Installing the Complete Rubber Tube Assembly

Note: O-ring connector configurations vary. Make sure there is an o-ring in each groove before re-assembly.

1. Apply o-ring grease to the o-rings on the o-ring connector.

Push the valve end tube fitting fully over the o-ring

connector in the valve journal.

2. Insert the non-valve end of the rubber tube assembly into

the shaft. Slide it all the way in until it seats in the recess

in the non-valve journal.

3. Apply o-ring grease to the fit area of the valve journal.

4. Align the match marks on journal and shaft

and tap the journal into place with a rubber mallet.

5. Apply small amount of low-strength threadlocker to

threads of the journal screws. Reinstall the set screws

and torque according to chart on page 12.

6. Reinstall the valve:

a. Apply a thread sealant (according to the

manufacturer's directions) to threads of the valve.

b. Screw the valve into the shaft and torque to 8.8-10 ft·lbs (12-13.6 Nm).

Disassembling a Rubber Tube Assembly

The standard rubber tube assembly, shown below, fits onto an o-ring connector that remains screwed

into the valve journal.

In some shaft designs, the o-ring connector is installed in the rubber tube assembly.

Your rubber tube assembly may have a tube stiffener installed inside the rubber tube.

Disassembly is similar for both configurations.

This rubber tube assembly consists of four basic parts: element, element fitting, end cap and jam nut.

(Older models may have a washer installed: it is no longer necessary with the use of Loctite 242.)

Note the difference in tube fittings:

Valve end fittings are bored through for air passage; non-valve fittings are solid.

Note: O-ring connector configurations vary. Make sure there is an o-ring in each groove before re-assembly.

Do not inflate rubber tube assembly outside of the shaft.

Tube fittings could disengage from assembly and become dangerous projectiles.

Can result in serious injury.
