D0008585B Rotary Ring Drive Pulley (for 8mm key) x 1

D0015801 Feather Key 8mm x 8mm x 22mm x 1

Étape 1 - Unless otherwise stated

Use Loctite 243 on all fasteners

Use Loctite 572 on all threaded pneumatic connection

Pen mark all fasteners to show finalised

Étape 2 - Quality Check

It is vital to check the correct pinion gear has been issued to build

D0001286B-2Mod should be issued

To check this is correct , perform a tooth count on the gear. If correct the gear will have 28 teeth it total

8mm keyway should be present

Report any dicrepancy through he correct reporting method

Étape 3 - Assemble drive spigot

1 Press B0000095 Bearing into D0006060 Spigot Cap so snap ring sits flush

2 Fit D0001286B-2MOD Welded Ring Pinion Gear 2MOD as shown Use jig to ensure bearing is not moved from location. Push through until circlip groove is in correct place

Check to ensure drive pinion does not contact bearing face as shown

Étape 4 - fit key and pulley

1 Fit Circlip 20mm and D0015801 Feather Key 8mm x 8mm x 22mm as shown

2 Fit D0008585B Rotary Ring Drive Pulley as shown . Only press down until circlip groove is present

3 Fit 20mm external circlip

4 Tighten Grubscrew with pulley pulled against circlip

Étape 5 - Attach to gearbox plate

1 Fit B0000095 bearing to D0006058 plate as shown . Note circlip on bearing to be on indicated face

2 Attach B0000092 Belt: Toothed 640-8MGT 20 as shown

3 Press pinion assembly onto gearbox plate

...Do not force past contact point indicated. This can cause distortion on pinion assembly

4 Secure lightly with 4 off M6 x 35 socket caps

5 Add 2 off 8mm x 50mm dowels into indicated holes . Ream if holes are tight

6 Finalise 4 off M6 socket caps

Étape 6 - Gear box bung supplied with gearbox C0001211

...Ensure plastic bung issued with gearbox remains with gearbox at all times for later fitting

Étape 7 - Check pulley fitment

Check D0000268 Rotary Drive Tooth Pulley fits onto C0001211 Gearbox

If pulley fits move to step 6, if it does not fit follow these steps

1 Remove key from gearbox shaft

...Take care not to damage shaft or keyway . Try clamping keyway in a vice to remove from shaft

2 Test pulley again for fitment.

• If the pulley still does not fit, polish inner face of pulley until fitment is achieved
• if the pulley does fit when the key is removed , move to next step

3 Refit key

4 Test pulley , if the pulley still doesn't fit correctly dress keyway slot gently until fit is achieved

Étape 8 - Fit Servo gearbox cap

1 Fit D0007849 Servo gearbox cap as shown. No adhesive on the 4 off M8 x 35 socket caps

Orientate as shown

2 Fit D0000268 pulley

Étape 9 - Couple and align gearbox and pinion assembly

Insert part1 through part 2

Hook over belt (3)

insert 4 off m8 x 50 with a form washers a pull to face lightly

Étape 10 - Align pulleys

Adjust pulley 1 up or down to match pulley 2 as shown

Étape 11 - Remove pulley assembly

Reverse steps to remove assembly 1

Remove part 2

...Ensure pulley retains its position through these steps

Tighten grubscrew to leave witness mark , Remove pulley and drill 5mm dimple at indicated point

Use M6 x 10 kcp grubscrew to lock pulley in final position

Rebuild parts to get to 3

Étape 12 - Tension belt

1 Attach tensioning jig as shown

2 Apply tension to belt , spreading tension over two bolts indicated . Maintain parallel on these faces as adjusting

Set belt tension to 5mm deflection (Drum Tight )

Étape 13 - finalise position

finalise 4 off m8 socket caps to hold tension

Remove setting jig plates

Étape 14 - Quality check

Quality check required on belt tension
