Replacement suspension?

Postby GoldWingRev » Wed Oct 02, 2013 4:18 am



Second post!
With all these wonderful answers my last post got--I've been saying for years that Wing riders look out for their own and are just great people in general. I was right.

I wanted to upgrade my rear suspension, but that turned out to be a fiasco. I have the suspension off another Wing that I bought from a salvage place. It is missing the bushings on the bottom though, like so:


I have some that are in my old suspension, and my other bike has the same suspension. Has anyone replaced these? My thought was a machine shop, as they look like they're pressed in. Does that sound right?

But how does one out the bushings into the shock?

That's not a bad price at all.

They just push in & out...Little dab of grease helps...The left one has a bushing/spacer in the bottom.

Yeah, I see that. It's where it connects to the frame, or the swing arm.

Well I must be weak if they push out. Maybe I'll get new ones and try to push them in. That's why I thought if a machine press.

Thanks, I'll go see what I can do.

Mine were pretty dried out and rotted...They came out pretty easy...I just took a screwdriver on one edge and just worked it out, pushing the new one in was harder. Just put a dab of grease inside the hole on the shock, will make it a lot easier.

Thank you. This has been a life saver, between all the ones I've read and these odd problems like in having now.

One question more about the suspension--I'm over 200 pounds (weightlifter, not fat, so it's an even heavier problem), and I heard the the transmission fluid in the shocks for compression don't work as well as fork oil. Does anyone find this to be true? What do youse recommend I out in, how much, and where exactly am I suppose to pour it
Thanks! I love knowing that there're people out there who can help me through this.

I used ATF, that's what the book said to use, 12.3 oz. While they are disassembled (seals out), I put a rubber stopper in the hose threads and turned them bottom side up, poured the ATF in from the bottom then replaced the bushing, washers, seal, and clip. make sure the plug you are using fits very tight without damaging the threads, when you press the seal in that will exert force upon the plug.

Maybe some others will chime in about the fork oil. I have only ridden mine around the block as I just got it going and it's not plated, but it seems to be a smooth ride.

I don't think I have a plug that's the "male" fit. Why can't I put it right side up and just pour from the top, where the rather smelly oil from before leaked out of? Use a funnel perhaps.

I know exactly why I can't fill from there--the air pushes the oil out. So, how exactly do I get the stupid clip off the plate on the bottom? I don't even have a compressor to get the seal off, but I can try to borrow one. I'm sensing this being more difficult than I had originally predicted.

You can it just takes longer. It's a small hole. I used one of those little rubber caps that snaps on the top of a bleeder valve. It just pressed right in and didn't damage the threads, then just kept pressure on it when I pressed the seal into place, just to make sure that the pressure didn't force it out.

Such as one on my brake bleeder? Do I have to apply pressure, like when putting air into a tire? Have to "open the linel," for lack of a better word? Sorry about all this, I'm tired and frustrated right now, and I appreciate your response. Thank you. :)

Snap ring pliers (a good, cheap investment), it can be done with a pick and a screwdriver but it's time consuming. Yes you will need a compressor to remove the seal. Take an old thick towel, fold it in half, stand the bottom of the shock in the middle, and fold the towel upwards and hold it tight. Place the tip of the blowgun in the threaded hole and give it a couple of short blasts, the seal will come out with some force and blow out any remaining fluid (very messy, hence holding the towel tight). It took me about an hour and a half to do both shocks (w/ snap ring pliers). Easier than doing the fork seals.

Keep at it it will be worth it in the end.

What size snap pliers? There seem to be a few.

I have a few different kinds, the ones I use the most are my Craftsman. they come with 4 or 5 different size tips and have a switch that allow you to use them both ways (internal/external). If I remember correctly I paid like $14.99 ish at KMart.

Just wet on my first extended ride of about 60 miles round trip, 30 of it I was alone. I went to pick up the wife from work last night. Before I left I did my usual check of everything. Added a little air to the tires and maxed out the shocks and forks since I knew I would be 2 up on the way home.

I did have a few times when it felt like we bottomed out the shocks. We are both just shy of the 200# mark (most of the time). So in answer to the question about ATF vs. Fork oil, if you haven't filled them yet you might consider the fork oil if you will be doing any riding 2 up. I think I'm going to change mine. I will be doing a lot of riding with her on back.

Maybe we can get some input from some of the others on this, and maybe even on the thoughts of hydraulic jack oil instead. Anyone ?

80-GL1100-INT (great UN btw):
Success! I found the tool and got the fluid in. The air seems to be holding at 25 PSI. Will take off center stand in the morning. Thank you so much.
