In addition, under the wavy washer is also an indexed washer with two tangs which face upward. It sits atop a T-shaped sleeve on the distributor shaft, which can be easily pulled upward prior to removing the distributor electronic sensor module.
The module itself is not rebuildable, but hardly ever goes bad. The lens might get dirty, or the cable might develop a problem, but there is not a lot of trouble with these, ordinarily. If you suspect the module IS defective, try to source a good used one at a junk yard or pick-n-pull.
Do not forget to place the washer here before you reinstall the electronic module.
The best method of removing the inner seal is to flip the housing over and use a long flat-bladed screwdriver inserted down the shaft hole to push the seal out by tapping the screwdriver with a small mallet. This will most likely destroy the seal, so ensure you have a replacement prior to attempting this. NOK 3286 is the part number. Check eBay for the Honda engines listed above ("F22B1 distributor seal").
Once the seal has been replaced, put a light film of grease inside the inner seal before inserting the shaft into the housing during reassembly. The bearing can be replaced at this time, as well, but sadly, I forgot to get a part number for it. Can anyone assist with this?
In order, from top to bottom on the distributor shaft, inside the housing, under the metal plate cover:
1) rotor button sleeve
2) slotted optical disk
3) wavy washer
4) two-tanged index washer (to align the disk)
5) T-sleeve
6) electronic module with three screws
7) small washer sitting atop the inner bearing (two screws hold the bearing in place)
8 ) inner bearing
9) inner seal
Hope this helps!
