Compatibility and Fitment
Check the current upper drive belt routing before ordering, especially on units with prior repairs or mixed replacement parts. Inspect pulley condition and belt tension at the same time, because wear in nearby components can shorten the life of a new belt. This part suits the following part numbers and applications. Installation changes may be required. 50-00178-26, 500017826, 78-604, 78604, BX83, CTC20-78-604, CTC2078604
Compliance and Safety
Shut the unit down before service and keep clear of moving belt-driven components while inspecting the drive path. Replace frayed, cracked or worn belts promptly, and recheck adjustment after initial running time on a new belt. If pulley alignment or belt tension is incorrect, correct that first because a new belt alone will not fix the drive system.
Trailer Applications
Optibelt Upper Drive Belt Ultima XTC X2 suits refrigerated trailer servicing where compatible Carrier Ultima XTC and X2 equipment remains in use. It is suited to scheduled maintenance, workshop replacement and service stock for transport refrigeration units that rely on the correct upper drive layout.
