same as a 350
Align the rotor with the number one position on the distributor cap, then with the engine at TDC insert the distributor. There may be a mark on the outside of the distributor to help.
The distributor is a single unit. Set the engine to top dead center. Make a witness mark on the distributor body and the engine case to reassemble and re-align the unit. Remove the distributor clamp holding the distributor in place. Remove and mark the wires. Pull the distributor straight up and out of the engine case. The shaft is keyed and should be in the body of the distributor. Reassembly is the reverse procedure.
Adjusting the distributor sets the ignition timing. To set timing you need to align the timing marks as specified by the manufacture using a timing light.
The air gap between the the tooth on the distributor shaft and the pick up coil should be .006. Be sure to use a brass feeler gage when setting the gap. Align blades good,And adjust to .008th.
To remove a distributor without messing up the timing, first mark the position of the distributor housing and the rotor's alignment with the engine before removal. Disconnect any electrical connections and remove the hold-down clamp, then carefully lift the distributor out without rotating it. When reinstalling, align the rotor with your initial mark to ensure the timing remains unchanged. Finally, double-check the timing with a timing light after reassembly to confirm accuracy.
To hook up the distributor for a 302 motor, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder number one. Align the rotor of the distributor to point towards the number one cylinder terminal on the distributor cap. Insert the distributor into the engine, making sure the gear meshes with the oil pump drive. Finally, connect the ignition wires to the corresponding terminals in the correct firing order, typically 1-3-7-2-6-5-4-8 for a 302.
To align the timing marks on a Nissan pickup with a 2.4-liter engine, first, ensure the engine is at top dead center (TDC) for cylinder one on the compression stroke. The timing marks on the crankshaft pulley should align with the pointer on the timing cover. The distributor rotor should be pointing towards the number one cylinder's terminal on the distributor cap. After aligning, double-check the marks and rotor position before reassembling the components.
To line up the oil pump and distributor in a 1989 Nissan 240SX, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the oil pump drive shaft so that it is vertical and the slot is facing the engine's front. Next, position the distributor so that the rotor points to the number one cylinder terminal on the cap. Finally, ensure the distributor is seated properly and secured before reassembling the components.
The distributor is set to 0 deg. Align the rotor to the line in the pickup plate in the distributor when the crank is at tdc. The dist. is then fine tuned with a scan tool.
If you've marked it properly, just align it with your marks. This will only take a few seconds. If, however, you failed to think about what you were doing during disassembly: -Turn the engine to cylinder #1 TDC on compression stroke. -Remove distributor cap. -Turn the distributor rotor to point at the #1 terminal on the inside of the cap. -Set the distributor in place and tighten it down. -Reassemble everything else required to run the engine. -Adjust spark timing.
