• Q: How to properly overhaul a distributor to ensure correct reassembly and prevent engine damage on 2004 Chevrolet Silverado 1500?

  A: To overhaul the Distributor go ahead and dismantle it first, mark the Distributor, driven gear, shaft, rotor holes, to ensure precise reassembling as wrong connection can result in no-start conditions & engine damage. Position the white paint mark of the bottom stem of the Distributor inside the pre-drilled indent hole in the bottom of the gear for the placement of the rotor segment for v6 engine; if not, replace the Distributor. Take off the screws from the rotor, and take out the rotor, while taking note of where the rotor screw holes and rotor locator pin holes are. Mount the cmp sensor screws into the square-cut hole in the vane wheel with the cmp sensor lined up, and remove and discard the cmp sensor. Watch the dimple below the roll pin hole on one side of the gear for correct orientation when assembling it. Support the driven gear in a v-block or similar fixture, drive our the roll pin with a suitable punch, remove the driven gear and round washer, loosen the tang washer and shim washer, and press the oil seal, as it cannot be removed and is incorporated in the listed washers. For assembly, align the square-cut hole on the vane wheel for cmp sensor and mount the cmp sensor with new screws (secure to 2.2 N.m./19 lb in), and then determine the correct rotor mounting holes. Install the rotor Distributor following the index marks, fasten it rotor screws to 1.9 n.m (17 lb. In.), install the shim washer, tang washer, round washer. Mount the driven gear where the index lines indicate, the rotor segment should align as indicated in a v6 engine, and the white paint from the bottom stem of the Distributor should be installed over the pre-drilled indent hole present at the bottom of the gear. Make sure that the dimple is correctly located. If the driven gear is placed wrongly, it will be about 180 degrees to the rotor segment. Position the Distributor drive gear in a v-block or an appropriate fixture, insert the roll pin using an appropriate punch and hammer, fit a new oil seal under the mounting flange of the Distributor base, and the last step is to fit the Distributor.
