STEP 1 REMOVE WINCH FROM DAVIT AND UNWIND ENOUGH CABLE TO ALLOW WINCH TO LAY ON BENCH. STEP 2 REMOVE CIRCLIP, BEING CAREFULL NOT TO LOSE OR OVER SPREAD AND DAMAGE.

STEP 3 LOOSEN GRUB SCREWS HOLDING COLLAR IN PLACE STEP 4 PUSH COLLAR UP AGAINST RATCHET GEAR.

STEP 5 MARK POSITION OF END CAP ON SPLINED SHAFT. STEP 6 TAP SPLINED SHAFT INTO GEARBOX, LEAVING END CAP IN PLACE

STEP 7 USING A SCREW DRIVER GENTLY LEVER END CAP OFF SPLINED SHAFT AND OUT THROUGH BRONZE BEARING. STEP 8 KEEP END CAP AND CIRCLIP SAFE

STEP 9 THIS IS THE IMPORTANT PART. HOLDING RATCHET WHEEL TURN THE 9 TOOTH GEAR CLOCKWISE TO TIGHTEN BRAKE MECHANISM. ONCE FINGER TIGHT IT SHOULD BE HOLDING THE RATCHET GEAR FIRMLY, PREVENTING ANY ROTATION. ( NOTE: WHILE TIGHTENING ENSURE 9 TOOTH GEAR IS OUT OF MESH WITH GEAR ON INTERMEDIATE SHAFT) STEP 10 ONCE TIGHT PUSH SHAFT BACK ACROSS INTO CORRECT POSITION. ( NOTE: THIS WILL RE-ENGAGE 9 TOOTH GEAR AND INTERMEDIATE GEAR)

STEP 11 LOOKING DOWN ON 9 TOOTH GEAR CRESCENT SHAPED CUT OUT. THIS IS WHERE LEG ON END CAP FITS. THE CRESCENT EFFECTIVELY LIMITS THE LOCK/RELEASE MECHANISM. AS THE WASHERS WEAR THE LEG WILL REACH THE END OF THE CRESCENT BEFORE IT LOCKS. SO WITH THE RATCHET NOW LOCKED ALIGN THE END CAP WITH THE LEG IN THE CUT-OUT AS FAR AS IT WILL GO IN THE ANTI-CLOCKWISE DIRECTION, THEN ROTATE 1 TOOTH CLOCKWISEAND RE-FIT. STEP 12 THIS SHOULD RESULT IN THE 2 MARKS NOW BEING 1 OR 2 TEETH OUT OF ALIGNMENT (SHOWING THE AMOUNT OF ADJUSTMENT ) . NOTE: YOU COULD TAKE A SHORT CUT AND SIMPLY REMOVE THE END CAP,...

STEP 13 REFIT CIRCLIP STEP 14 REPOSITION COLLAR LOCATING GRUB SCREWS IN DIMPLES ON DRIVE SHAFT. STEP 15 I AM SURE I HAVE MADE IT SOUND MORE DIFFICULT THAN IT REALLY IS SO IF YOU ARE NOT SURE LET ME KNOW AND WE CAN GO THROUGH IT 1 STAGE AT A TIME. STEVE BIRD
