Keep the alternator, air-conditioning compressor, and cooling fan turning with the Gates Accessory Drive Belt 2/9550PB. It loops over the accessory pulleys to transfer rotational power from the crankshaft to the belt-driven accessories, and it drops in as a direct-fit replacement for the listed heavy-duty applications — including the 1990-1994 Freightliner FLA086 and the 1990-1997 Freightliner FLD120.

  • Accessory drive: Serves the alternator, air conditioning, and fan/alternator accessory drives on the listed applications.
  • How it works: Routes over the accessory pulleys, transferring engine power so the driven accessories spin at the correct speed.
  • Signs it may need replacing: Belt squeal, visible cracking, glazing, fraying, or chunking — if a worn drive belt is the cause, this replaces it.
  • Direct fit: A direct-fit replacement for the listed Freightliner and Mack applications.

Fitment: 1990-1994 Freightliner FLA086; 1990-1993 and 2000 Freightliner FLC112; 1990-1997 Freightliner FLD120; 1990-1991 Mack MR; 1991-1994 Freightliner FLD112; 1992-1993 Mack CL; 1994 Freightliner FLB. See the Buyer's Guide tab for the full list.
