CAUTION
DONOTlubricateoruseoilonanymovingparts.Thecompressoreccentricusesa
precisionsealedbearing.
DONOTcrimpthepistoncupwhenyoureplacethesleeve.Ifthecupiscrimped,itMUST
bereplaced.
3. Withbearingsideofconnectingrod/eccentricassemblyfacingthecenter(motor)of
thecompressor,slide theassemblyontotheshaftbringingitflushtothemotor
bearing.
NOTE:Makesuretheeccentricsetscrewispositionedovertheflatoftheshaft.
4. Usingtheaccesshole,tightensetscrewto
40inch‐lbs(Detail“A ” ofFIGURE 7.4).
5. Holdthesleevedowntothehousingwithonehandandslowlyrotatetheeccentric
withtheotherhandtoensureallthecomponentsarealignedproperly.
Fan
NOTE:Forthisprocedure,refertoFIGURE 7.4onpage 36.
1. Reinstallthefanontotheshaftinoriginalorientation.Secureintopositionusinga
rubbermallet.
Valve Plate
NOTE:Forthisprocedure,refertoFIGURE 7.3onpage 35.
1. Withthesleevelocatedandfirmlyseatedonthehousing,replacethevalveplateinthe
samemannerasitwas.
2. Repeatstep1forothervalveplate.
NOTE:MakesurethetopedgeofthesleevelocatesintheO‐ringgrooveinthebottomofthevalve
plate.
CAUTION
MakesurethattheO‐ringisnottwistedwhenseatedinthegrooveofthebottomofthe
valveplate.
Compressor Heads
NOTE:Forthisprocedure,refertoFIGURE 7.3onpage 35.
1. Placetheheadsontopofthevalveplates.
2. Tightentheheadscrewsinacriss‐crosspatternto40inch‐lbs.
