32B65-04221 is supplied as a remanufactured replacement fuel injection pump. Application recorded for this part: Fits Caterpillar S6S / CAT3046 engine. Supply pressure, timing and delivery quantity are all set here. Failures tend to progress gradually — a little more smoke, slightly harder starting when hot, slowly rising consumption — which is why the number stamped on the pump is the reliable way to match a replacement. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Units outside specification are not dispatched, test sheets are available on request, and every unit carries a 12-month warranty.
