Introduction

Tools Required

Standard hex key set

Stubby hex key set

Wire line

Quick clamps

P0000501 non return valve x 3

Standard HSS drill set

Standard tap set

Tape measure

300mm rule

Parts Required

D0015625 x 1

D0015625-OH x 1

E0000336L x 2

Étape 1 - Drive pinion mesh setting

Mesh requires setting between slider unit and drive pinion

1 It is vital that the correct drive meshing is achieved.

2 Once set, there should be 1mm movement in the direction shown, which will indicate the correct tooth meshing has been obtained.

3 This need to be checked at all points of travel as shown

Étape 2 - Check for clearance

Clearance check must be completed at this stage

Interference may be possible from bearing block fasteners indicated against drive rail

Space M10 cap heads with M10 washer is drive rail contacts fastener end

Étape 3 - Set mesh

1 Slide drive pinion into position 1 under drive rack

2 Use M4 adjuster screws to adjust height of rack and M6 to secure

3 Slide out drive pinion and move rack to position 2. Refit drive pinion

4 Use M4 adjuster screws to adjust height of rack and M6 to secure

5 Repeat steps until correct meshing is present at all points indicated to check

Do Not glue any of the M4 /M6 socket caps used for adjustment as this will be done at a later stage

Étape 4 - Repeat

Repeat step two for remaining 8 slider units

Étape 5 - Alignment

Alignment of cylinder pins is vital, and the following should be maintained

1 Alignment should be parallel to main hepco beam

2 Alignment should be Straight

To achieve this the following steps are required

Étape 6 - Set First and last position

1 Set First and last slider into the position shown to align indicated hole with fixing point on support arm. Slide pinion into position once slider has been moved to correct point.

2 Fine adjustment can be gained by Removing tension off M6 bolt on drive rail , and using slot to change position of drive rail mounting . Use Socket cap bolt to lock position onto support arm

3 Check measurement between pin and hepco beam on both sliders to ensure they are the same.

Étape 7 - Please note

Cylinders do not require to be piped up to complete this step .

Non return valves are stated in the following steps to be used, thus negating the requirement to run pipe looms

Étape 8 - Set Wire line

Use dokit Alignment guide using wire line to ensure alignment is completed correctly

1 Attach P0000501 non return valve with 6mm pipe to first and last cylinder and purge with air to maintain active position of cylinder.

2 Set wire line between these two active cylinders

Étape 9 - Adjust Remaining slide units

Remaining slide units now need adjusting to align to the wire line .

Adjust one at a time, and use a P0000501 non return valve and 6mm pipe to purge each cylinder as you work on it.

Use movement in slots indicated to adjust smaller increments once drive rail has been positioned

Once a cylinder is set, remove non return valve and place on next cylinder being set

Étape 10 - All pin positions must be checked

All pin positions must be checked with a steel rule measured squarely to the hepco rail

All measurements must be to a tolerance of -+0.5mm

Étape 11 - CAUTION!!!

...Until rack stops are fitted, it is possible to over position slide units and they will run off drive pinions, and loose all settings previously set. Take care and follow good practice

Étape 12 - Fit rack stop one D0015626

1 Assemble one off D015625 and 1 off D0015625 -OH as shown using a M6 x 25 hex set bolt and 2 M6 nuts.

2 Rotate drive shaft to position rack as show

3 Position rack stop as shown and mark, drill and tap to M6 . Ensure M6 hex set bolt is set as shown for maximum adjustment

Use M6 x 16 socket caps and A form washers to fix

Étape 13 - Fit rack stop 2 D0015626-OH

D00015629 Rack extension

1 Assemble rack extension and hard stop bracket as shown using 2 off M6 x 16 socket caps and 2 off M6 A form washers . Fit hard stop bolt 1 off M6 x 25 set bolt and M6 Standard nut as shown 2 Fit assembly to arm number ( clarify which arm this is fitted to please)

Drill and fix with M6 x 16 socket caps and A form washers
