ENSURE THE PLUG GAUGE AND THE BORES OF THE PROPELLER IS

TOTALLY FREE OF RESIDUES OR GRIT OF ANY KIND.

EVENLY DISTRIBUTE BY HAND THE BLUEING COMPOUND (PERMATEX NON-DRYING PRUSSIAN

BLUE-PART #35V ITEM #14) TO THE PLUG GAUGE SURFACE TO FORM A LIGHT FILM.

NOTE: EXCESSIVE BLUEING COMPOUND WILL PREVENT THE RING GAUGE FROM SEATING

IN THE HUB BORE.

POSITION THE BORE OF THE HUB VERTICALLY SO THAT THE LARGE END OF THE BORE

IS FACING UP.

LIFT THE PLUG GAUGE VERTICALLY BY ITS EYE BOLT ABOVE THE BORE. A BLOCK

AND TACKLE OR OVER HEAD CRANE LIFT IS REQUIRED.

ONCE ALIGNED TO THE BORE, ALLOW PLUG GAUGE TO FREE-FALL FROM A HEIGHT OF

3-3/4" FROM THE LARGE END OF THE PLUG GAUGE. TO ACCOMPLISH THIS, IT IS

RECOMMENDED THAT A NYLON STRAP BE ROUTED THROUGH THE EYE AND UNHOOKED MANUALLY.

WIPE OFF ANY BLUEING COMPOUND ABOVE THE PLUG GAUGE STANDOFF AREA.

AT 120° INTERVALS, MEASURE THE DISTANCE WITH A DIGITAL CALIPER FROM THE STAND-

OFF POINT TO THE FACE OF THE HUB TO ENSURE THE PLUG GAUGE IS WITHIN TOLERANCE.

REFER TO THE DRAWING FOR THIS MEASUREMENT. SEE GENERAL NOTE #4.

SLIDE THE BRASS RING ONTO THE PLUG GAUGE UNTIL THE RING RESTS ON THE FACE OF

THE HUB.

HAND TIGHTEN THE HYDRAULIC NUT UNTIL IT RESTS SNUG TO THE BRASS RING.

USING THE HYDRAULIC PUMP, APPLY THE REQUIRED PRESSURE TO RELEASE THE PLUG GAUGE

FROM THE BINDING ACTION OF THE HUB. OBSERVE THE PLUG CAREFULLY TO DETECT WHEN

THE PLUG RELEASES FROM THE BORE OF THE PROPELLER.

REMOVE THE HYDRAULIC NUT AND BRASS RING WITHOUT ALLOWING THE PLUG GAUGE TO MOVE.

IF THE PLUG GAUGE TWISTS IN THE BORE, THE READINGS WILL BE FALSE AND THE PROCESS

MUST BE REPEATED FROM STEP 1 ABOVE.

REMOVE THE PLUG GAUGE BY LIFTING UPWARD BY THE EYE BOLT ENSURING NO CONTACT WITH

THE BORE.

TAKE THE BLUE CONTACT READING IN ACCORDANCE WITH THE REFERENCE DRAWING FOR

GAUGING THE TAPERS. SEE REFERENCE #4 GENERAL NOTES.

IT IS NOT UNCOMMON TO REPEAT THESE PROCEDURES MORE THAN ONCE TO ENSURE A PROPER

FIT AND DRAW READINGS. AT TIMES, THE PLUG AND RING GAUGES WILL FIT DIFFERENTLY

DUE TO AMBIENT TEMPERATURES.

YOU SHOULD RETRY THE PROCEDURE IN DIFFERENT ENVIRONMENTAL CONDITIONS IF IT IS

DIFFICULT TO PROVE THE FIT. HOWEVER, THE PLUG GAUGES AND HUBS OF THE PROPELLERS

SHOULD BE AT THE SAME TEMPERATURES.

AFTER THE INSPECTIONS ARE COMPLETE, PROPERLY PROTECT THE PLUG GAUGE WITH

THE PROVIDED PROTECTIVE COVERING TO ENSURE THAT SURFACE DAMAGE CANNOT OCCUR.

ENSURE THAT ALL DUST COVERS ARE PUT IN PLACE ON ALL HYDRAULIC EQUIPMENT.

CAUTION : AT NO TIME IS ANYONE TO STAND IN FRONT OF THE HYDRAULIC ASSEMBLY WHEN

REMOVING THE PLUG GAUGE.

ONCE ALIGNED TO THE SHAFT TAPER, PUSH THE RING GAUGE ON FROM A DISTANCE4.

OF 3-3/4" AWAY. TO ACCOMPLISH THIS. IT IS RECOMMENDED THAT A NYLON STRAP

BE ROUTED THROUGH THE EYE OF THE RING GAUGE AND HOOK OF A BLOCK AND TACKLE

OR OVERHEAD CRANE ASSEMBLY.

WIPE OFF ANY BLUEING COMPOUND ON THE SHAFT ABOVE THE RING GAUGE.5.

AT 120° INTERVALS, MEASURE DISTANCE WITH A DIGITAL CALIPER ON THE SMALL END6.
