PRECAUTIONSANDPREPARATION
Precautions forRefrigerant Connection
WARNING: Make sureallrefrigerant isdischarged intotherecycling equipment andthepressure inthe system is
less than atmospheric pressure.Thengradually loosenthedischarge sidehose fitting andremove it.
CAUTION:
When replacing orcleaning refrigerant cyclecomponents, observethefollowing.
• When thecompressor isremoved, storeitin the same position asitis when mounted onthe car.
Failure todo sowill cause lubricant toenter thelow pressure chamber.
• When connecting tubes,always useatorque wrench andaback-up wrench.
• After disconnecting tubes,immediately plugallopenings toprevent entryofdirt and moisture.
• When installing anair conditioner inthe vehicle, connect thepipes asthe final stage ofthe opera-
tion. Donot remove theseal caps ofpipes andother components untiljustbefore required forcon-
nection.
• Allow components storedincool areas towarm toworking areatemperature beforeremoving seal
caps. Thisprevents condensation fromforming inside
AIC
components.
• Thoroughly removemoisture fromtherefrigeration systembeforecharging therefrigerant.
• Always replace usedO-rings.
• When connecting tube,apply lubricant toportions showninillustration. Becareful nottoapply
lubricant tothreaded portion.

• O-ring mustbeclosely attached toinflated portionoftube.
• After inserting tubeintounion untilO-ring isno longer visible, tightennuttospecified torque.
• After connecting line,conduct leaktestand make surethatthere isno leakage fromconnections.
When thegas leaking pointisfound, disconnect thatlineand replace theO-ring. Thentighten con-
nections ofseal seattothe specified torque.

SERVICEPROCEDURES
Maintenance ofLubricant Quantityin
Compressor (Cont'd)
@
1. Discharge refrigerant intotherefrigerant recovery/recycling equipment.Measurelubricantdischarged intothe
recovery/ recyclingequipment.
2. Remove thedrain plugofthe "old" (removed) compressor (applicableonlytoV-5, V-6orDKS-16H compressor).
Drain thelubricant intoagraduated containerandrecord theamount ofdrained lubricant.
3. Remove thedrain pluganddrain thelubricant fromthe"new" compressor intoaseparate, cleancontainer.
4. Measure anamount ofnew lubricant installedequaltoamount drained from"old" compressor. Addthislubricant to
"new" compressor throughthesuction portopening.
5. Measure anamount ofnew lubricant equaltothe amount recovered duringdischarging. Addthislubricant to"new"
compressor throughthesuction portopening.
6. Torque thedrain plug.
V.5 orV-6 compressor: 18-19 N'm (1.8-1.9 kg-m, 13-14 ft-Ib)
DKS.16H compressor: 14-16 N'm (1.4-1.6 kg-in, 10-12 ft-Ib)
7. Ifthe liquid tankalso needs tobe replaced, addanadditional 5mC (0.2 Imp IIoz) oflubricant atthis time.
Do not add this5m C(0.2 ImpIIoz) oflubricant ifonly replacing thecompressor.

•Using theholder toprevent driveplaterotation, tightenthe
bolt to12to15 N'm (1.2to1.5 kg-m, 9to 11ft-Ib) torque.
After tightening thebolt, check thatthepulley rotates smoothly.
• Check clearance aroundtheentire periphery ofclutch disc.
Disc-to-pulley clearance:
0.3 -0.6 mm (0.012 -0.024 in)
If the specified clearance isnot obtained, replaceadjusting
spacer andreadjust.
BREAK-IN OPERATION
When replacing compressor clutchassembly, alwaysconduct •
the break-in operation. Thisisdone byengaging anddisengag-
i
ing the clutch aboutthirtytimes. Break-in operation raisesthe
level oftransmitted torque.
