SHUT DOWN PACK 1 AND TAXIED QUICKLY TO THE GATE.

FIM CALLS FOR RH ACM AS THE FIRST PROBABLE CAUSE UNDER R PACK AUTOFAIL. ATTEMPTED TO SPIN OLD PACK BY HAND AND NOTICED A LOT OF RESISTANCE COMPERED TO THE NEW PACK. SUSPECT R PACK TO BE GETTING SEIZED UP. REMOVED AND REPLACED R PACK ACM IN REF TO AMM 21-51-08 WITH APU AND ENGINES OPS CHECK GOOD AT THIS TIME WITH NO SMELL OR SIGNS OF SMOKE.
