To replace the Distributor, users should turn off the ignition, remove the air cleaner assembly. Remove the Spark Plug Wires from the Distributor with the bootstrap twisted 1/2 turn and a pull on it only. Next, pull off the electrical connector at the base of the Distributor and the two screws that hold the Distributor Cap to the housing, throwing away the screws afterward. Pull off the Distributor Cap and then mark the position of the rotor with reference to the Distributor housing and Intake Manifold using a grease pencil. Remove the mounting clamp hold down bolt and redistribute leaving the left in place writing down the rotor will move counter-clockwise about 42 degrees upon removal. For installation procedure 1 for using a new Distributor assembly, copy the marks off of the new housing, line up the rotor's end with the mark number two and feed the Distributor into the engine, ensuring that the hold down base is against the Intake Manifold hole. As the Distributor is installed, the rotor should turn clockwise approximately 42 degrees and after seating, rotor segment has to be set at the first mark. If there is misalignment, take out and install the Distributor. Slacken the Distributor clamp bolt to 25 n.m (18 lb ft), install the Distributor Cap using two new screws with 2.4 n.m (21 lb in), rewire the electrical connector, and plug in the Spark Plug Wires and ignition coil wire, in the correct orientation. Once the malfunction indicator lamp or mil comes on and there is a dtc p1345, the Distributor is misinstalled. In installation procedure 2, turn the number 1 cylinder to the top dead center (TDC) of compression stroke, with crankshaft balancer marks coinciding with the engine front cover tabs. Mount the steel gear on a wooden block of wood supported by the magneto base and turn the brass index until its red line coincides with the white paint mark made on the Distributor's bottom stem. Then, align the gear hub onto the hole made in the gear. On an oily pump drive shaft align with the Distributor's drive tab, guide Distributor into the engine tbd takes spark plug towers should be perpendicular, and rotor segment with pointer in Distributor base. If alignment is not perfect, then redo the process. Finally, you should install the Distributor mounting clamp bolt, which must be stretched down to 25 n.m (18 lb ft), installer the Distributor Cap with new screws tightened to 2.4 n.m (21 lb in), install the electrical connector, install the Spark Plug Wires and ignition coil wire remembering the correct orientation. If mil is activated and dtc p1345 is found, the installation of the Distributor was incorrect and to do the repetition of installation procedure 2 is needed.
