Showa shock on 86 Interstate

Postby Mikeanthony » Tue May 17, 2016 9:09 am



I am trying to disassemble a pair of Showa air shocks which were on a 1986 Interstate. I have compressed the spring and removed the cap but the shaft will not come out of the main part of the shock. There is no circlip to remove, only a thin wire keeper that can be seen from the big end. In all the videos, the circlip is removed and everything falls out. What do I have to do here to get the guts out?

The upper slide bushing is keeping it from coming loose.The upper slide bushing is retained by a washer and circlip(#34)
.Remove the clip.You may have to push the slide into the tube and pull hard a few times to knock the slide loose.Pull straight out like you would operate a dent puller.
A new slide is reseated with the proper tool.Either from Honda or,as I do,a chunk of PVC pipe to safely tap it back into place.
Be careful of tolerances. The fork must slide butter smooth full stroke with no binding or wiggle.

Thanks a bunch for the diagram and the walk-through. I did finally realize that the little wire clip in my shock is now what used to be a circlip on the older units. I appreciate the help.

Are you planing on replacing the slide bushings.?
I've had to deal with bad front ends on all my bikes.Some just worn out, others badly abused.I did find a few tricks that are not mentioned very often about the reassembly procedure and testing.certainly not by the book.

My bad. I forgot to mention that I am now doing the rear shocks. I plan to do the front next so any tricks you have picked up will be welcome. I managed to get the rear broken down after I realized that there was no regular circlip. I still have to figure out how I can handle the front springs.

actually I've had the best luck assembling the front end and putting the springs in last.
There are easier ways but they don't allow for any checking.
I know,it's tough to stand on the seat holding a tool,compressing the spring and trying to turn the cap.
I do mark my cap so I know where the threads catch.
I did rebuild my forks..It took about 6 hours...tedious alignments and checking but the end result was amazing.
