Use compressed air to clean all areas #V edge should be checked for damage. Check entire circumference with fingers to identify any damage, lumps or high low spots #Check drive ring has been countersunk in the shown area Check that D0007651faceplate holes indicated (1) are countersunk the same as holes indicated (2 ). If not , countersink to correct 3. Clean all holes with compressed air Thoroughly clean faceplate with solvent Journal washers should be inspected to ensure all washers supplied are within tolerance . Thickness of washer should not exceed 0.05mm difference between all washers supplied. Report any that are incorrect via NCR system B0000185 and B0000186 journals should be cleaned with compressed air and checked for quality. Visually inspect v grooves of journals for and damage or irregularities D0007692 should be checked for correct machining. Holes indicated are vital to allow oil flow to ring system once assembled. Face plate should be positioned ready for assembly 1 Support blocks should be placed either end of faceplate 2 Ensure cut out is orientated correctly as per picture. This is the lifting access point. 3 Ensure correct end of faceplate is located at edge of workstation (end with 6 off M8 tapped holes on indicated face) Mount journals as shown <br/><div class="icon-instructions caution-icon"> <div class="icon-instructions-icon"><i class="fa fa-exclamation-triangle"></i></div> <div class="icon-instructions-text">...Do not use any adhesive at this point</div> </div> Eccentric B0000185 journal 6 off Concentric B0000186 journal 2 off Space each journal with D0006503 journal washer Fit Journal washer and nut to opposite side of mounted journal .

It is vital that the D.T.I is used to gauge if a journal moves when the nut is torqued to the correct setting . Use the following sequence to set correctly <br/> * Use flat hepco spanner to help stop rotation of journal when tightening * Ensure D.T.I is in front of journal being tightened to indicate if movement occurs * Use Torque wrench set to 33nm and tension journal nut. * If the D.T.I indicates movement, it is vital the movement is corrected as this will affect journal contact and concentricity . * Only move to the next journal when the worked on journal is 100% set and tight * Mark each journal as tensioned when complete After tensioning is complete, recheck concentricity with D.T.I and also check journal tension. Ring rotation should be smooth but with resistance No high spots on rotation should be present. Rotation should be quiet and even sounding Supervisor check required at this point <br/> D0006521 blank wiper spacer 2 off D0007693 oil access spacer 2 off 1 Fit D0007693 spacers with D0007692 wiper with m4 x 16 cap heads and M4 a form washers to area shown in picture with 1/4 bsp oil hole 2 Fit D0006521 blank wiper spacer with D0007692 wiper with m4 x 16 cap heads to area shown D0007713 rotary ring inspection 1 Thoroughly clean with Fe10 solvent and then compressed air 2 Check indicated face for damage 3 Check indicated face for signs of damage 4 Add 1 off m6 x 120 studding (cut from stock) to indicated hole.

It is vital this doesn't happen as it can render parts useless for application. Tension should be applied in small increments, and a D.T.I should be used on tension setting to monitor journal movement when adjusting and tightening. D.T.I and mag base and stand should be mounted to rotary ring as shown <div class="icon-instructions caution-icon"> <div class="icon-instructions-icon"><i class="fa fa-exclamation-triangle"></i></div> <div class="icon-instructions-text">......Correct tension setting for a journal is as follows - Journal will rotate when ring in rotated . - Journal can be skidded on ring when held by hand and ring is rotated - no Rattle is present from movement of ring in a sideways direction</div> </div> <br/> *move the D.T.I to the position in front of a concentric journal (1) and zero D.T.I. *move to position 3 and adjust journal to achieve slight contact. Use the D.T.I to gauge when contact occurs when adjusting. Stop when slight movement is visual on the D.T.I *repeat at position 4 *Check that all journals can still be skidded when held whilst ring is rotated <br/> *Move to position 5 and adjust journal to achieve correct contact using the same method as the previous step *Move to position 6 and repeat *Repeat at positions 7 and 8 Now it is vital to check the following . Rotate ring and check all journals can be skidded when held by hand Return D.T.I to journal 1 and set to zero Check reading now on all journals . Slowly adjust eccentric journals to bring D.T.I to +- 0.05mm Ensure attention is paid to tension applied to journals, to ensure overtightening does not occur. Journals should always be able to be 'just' Skidded when held with firm hand pressure Repeat these steps until all journals are adjusted to main rotary ring and all can be 'just' skidded when held tight on ring rotation. Maximum tolerance for eccentricity is 0.05mm , so if journals have to be adjusted out of this tolerance, contact supervisor Check faceplate has pre drilled 3 off M5 tapped holes on indicated face . Drill by hand if not present to dimensions shown before assembly commences It is vital to check that the correct ring has been issued to production To check, measure pitching of teeth as shown.
