1 Removal and replacement of the 1994 Nissan Altima Distributor Oil Seal NOTE: I m not responsible for any damage you may cause to yourself or your property as a result of the guide. Please take proper safety precautions and further research before taking on this project. This guide is for educational use only. This is a side view of the distributor. The top portion is what is inserted into the cam while the bottom is what faces out from the right of the engine. No distributor cap is shown. I got this distributor from somebody that said the bearing was bad. So the distributor was useless to them. Top view rotor now shown.

2 Top view rotor now shown. The dust cap comes off from the distributor when the distributor cap is removed. Shown here is the metal timing plate as well as shown are 3 screws.

3 There are no screws that hold the distributor together. The knob on the top is machine pressed onto a shaft that extends the entire length of the distributor. There is no clearance below to use a puller or appropriate device to remove the knob without damaging the top plate. The only way I found was to use two wrenches. Position one wrench on the bottom of the distributor to keep it from turning. Position the other wrench on the top. Use some sort of cloth or cardboard to keep from damaging the knob. I tore a piece of Coke cardboard off and put it between the wrench and the knob With both wrenches tight on their positions turn the top one slowly with quick even turns while at the same time pulling it up. NOTE: IT WILL REQUIRE A LOT OF FORCE TURN THE KNOB OFF THE SHAFT. IT IS IMPORTANT THAT YOU DO NOT DAMAGE OR SCRATCH THE TIMING PLATE. THE TIMING PLATE IS EASY TO WARP. The whole idea is that while you turn it and pull it up the knob will come off as it did in my case. This is the hardest part of the entire disassembly. As you see there are no threads on the shaft or the knob. As you see there are no threads on the shaft or the knob.

4 In this case I ve removed the timing plate as well a washer beneath the plate. Remove the 3 screws as indicated by their arrows.

5 Lift off the plate There is a dust cap gasket that needs to be removed to. It can be removed earlier but I decided to remove it now. This normally comes with a new cap and wires.

6 Remove the electronics. I m not sure of its entire function but this device reads the direction of the timing marks on the plate and knows where the cam is. Remove the collar off of the shaft.

7 I m pointing to the shaft bearing hold down plate. It contains two screws as indicated by the arrows and my screwdriver.. Screws removed

8 Remove the plate. Be careful with this part. You must use a hammer to push the entire distributor shaft out from the bearing. Use two 2X4s to do this. Put a piece of rubber or a cloth on the top of the shaft. Hit the shaft with direct and hard taps this will push the shaft out from the bearing.

9 The shaft is out. The bearing Another close-up

10 0 of 11 FINALLY THE OIL SEAL!!!!!!!!!!!!!!!!! If the oil seal is bad as in most cases it can simply be removed with a screwdriver taking pieces of it on the way out. The removed oil seal As far as the size or dimensions of the oil seal I have no clue. But if you read closely in the picture you can see the company is KOK. KOK as I found is a company in Taiwan that makes oil seals as well as other rubber products. The

11 1 of 11 top of the seal has numbers on it. It reads as follows: KOK, HSCL, 12.45, 22, 6, 4220, 72. These are all the numbers from left to right starting from KOK. The website for the company is They have a branch office in Irvine, CA. But I m sure you can go to your local parts counter and match up this oil seal with something they have in stock.
