O. SlipRingModificationandInterchangeability

(1) A slip ring assembly that is used on an application with synchrophasing requirements requires holes for installation of a synchrophaser target. Refer to Table6-2fortheoriginalconfigurationofaslipringassembly.

(2) Except for the synchrophaser target and/or the hole(s) for installation of a synchrophaser target, one slip ring of the same base part number may be identical to another slip ring assembly.

(3) A slip ring assembly with holes for a synchrophaser target may be used on an application without synchrophasing requirements when the synchrophaser target is removed.

(4) A slip ring assembly without holes for a synchrophaser target or with a different holepatternforsynchrophasertarget(s)maybemodifiedinaccordancewithTable 6-3.

(a) Modifytheslipringassemblyinaccordancewiththeinstructionsspecifiedin Table 6-3.

(b) Aslipringassemblymodifiedinaccordancewiththeinstructionsin Table6-3isanalternateforslipringassembliesasspecifiedin Table 6-4.

(5) SlipRingModification

(a) Refer to Table 6-3 to determine the applicable Slip Ring Assembly ModificationInstruction.

CAUTION: DO NOT PERMIT THE DRILLED HOLE TO CONTACT THE COPPER SLIP RING.

(b) Drillasynchrophasertargetholeinthelocation(s)specified:

1 Using a #50 drill bit, drill a hole 0.070 inch (1.77 mm) in diameter to a maximum depth of 0.166 inch (4.22 mm).

2 Using a 2-56 UNC-2B tap, tap the hole to a maximum depth of 0.135 inch (3.43 mm) with a minimum full thread depth of 0.100 inch (2.54 mm).

(c) Chamferthehole45+/-5degreestoadiameterof0.093-0.113inch(2.36 - 2.87 mm).


Page6-39 Rev. 5 Jun/15REPAIR/MODIFICATION 30-60-81

(d) If copper from the copper ring is exposed in a hole, a synchrophaser target may not be installed in that hole.

1 If copper from the copper ring is exposed and another hole can be used for installation of the synchrophaser target, plug the unused holethathasexposedcopperusingadhesiveCM93-1RTV123orequivalent.

2 If copper from the copper ring is exposed and another hole cannot be used for installation of the synchrophaser target, replace the slip ring assembly. The slip ring assembly is not serviceable.

(e) Afterslipringmodification,useanohmmetertomeasurethecontinuityin accordance with the De-ice Slip Ring Assembly Insulation Resistance Checks in the Check chapter of this manual.

(6) Stampingof"MOD"ontheModifiedSlipRingAssembly

(a) Usingaroundbottomimpressionstamp,stamptheapplicablemodificationconfigurationimmediatelyfollowingtheslipringpartnumberinaccordancewithSlipRingAssemblyModificationInstructions.

(b) Stamping "MOD" on a slip ring assembly when the synchrophaser target is removed is not required. Refer to Table 6-4 for the slip ring assembly alternates.



P. Installation of a Synchrophaser Target

(1) Install a synchrophaser target.

(a) Location for installation of the synchrophaser target

1 Refer to Figure 6-15 for the location of the synchrophaser target for Hartzell Propeller Inc. slip ring assemblies 4(E,H)1555-(2,3).

2 The location of the synchrophaser target(s) for other Hartzell PropellerInc.slipringassembliesisspecifiedintheaircraftTCorSTC holder's ICA.

(b) For Hartzell Propeller Inc. slip ring assemblies use the synchrophaser target 2H1377.
