"The Nissan part # is 11920-77A00TM. This belt is for running just the alternator, no AC, it is 1 rib skinner than the stock belt."


I recently bought a belt from Checker for my '93 SR20DE without A/C with UR 2 piece set = crank & water pump.
Gave them the Gates K040310 number and they cross-referenced it to the brand they carry. It is a 4 rib belt, installed fine, but haven't run the engine yet - waiting for more parts.
