How to replace distributor 1993 Honda Accord...
Take note of the position of each plug lead. Mark them with whiteout or tape and a pen if they have no distinguishing marks, or if you are unsure of their relative position.
Using a timing light on cylinder No.1, take note of the present timing marks on the crankshaft pulley with the vehicle up to temperature and running. You also need to take note of the engine revolutions when checking. Using paint, or a scribe, mark where the old distributor is aligned in reference to the engine head. These will serve as an approximate reference when refitting the new one.
Once your notes and marks have been taken, assuming you have no instructions on what the timing and rev range should be normally, then you can procede with the removal of the distributor.
Take off the distributor cap and take note of the position of the rotor arm and which direction it is pointing to. You will have to align the new distributor's rotor arm to the same point before installation.
Many distributors have two locating/locking bolts. You can remove these both, then pull out the distributor. It may require a bit of coaxing as it has a rubber sealing ring on it's shaft which may make it stiff when removing.
As soon as the distributor comes out you will notice that the distributor's drive shaft has two metal lugs which slot into the camshaft. Those metal lugs on many Japanese models are offset, allowing you only one way to fit the new distributor, or in other words, to make it impossible to set the distributor 180 degrees in the wrong direction. This is not always the case however, which is why taking note of the rotor arm earlier was important.
When refitting a new distributor it is often wise to fit it with a new rubber shaft seal. Apply a little rubber grease when refitting, or a smear of engine oil, making it easier to slide in.
Once in, roughly align your distributor at the angle the old one came out at, then secure lightly with one of the retaining bolts. I say lightly, because you will need to turn the distributor later to set the timing.Replace the cap and leads.
Often there is a sticker under the hood/bonnet which tells you what the timing should be at which engine idle rev range.If you are having problems keeping the engine at that specific rev range, then disconnect the idle control valve wiring connector and have someone sit in the vehicle to manage the throttle by the pedal.
Make sure the vehicle is up to temperature once again. The engine may run a little rough at this point, as your timing isn't set yet.
Referring to either your own notes or to the sticker under the hood, use the timing light again and turn the distributor until the crank shaft timing marks align to the correct position, then secure the distributor's locking bolts.
Run the vehicle for a few hours or days, and check the distributor for any signs of an oil leak. An oil leak generally occurs if the shaft seal ('O' ring) is not fitted correctly or if the rubber is damaged/perished.
