Rear Shock air question

Post by Breyno » Fri Oct 04, 2019 8:04 pm



Hi all,

A while back, the compressor on my GL1500A (93) broke. The little piston and connecting rod just shattered. I have put the compressor back together without it at this point in time.

I recall reading somewhere the best way to inflate the shocks without the compressor. Can someone point me int he right direction. Also any idea where I can source a new piston/ring and connecting rod.

Cheers
Reyno.

Short of finding parts to fix the compressor, why not just use a small Air Compressor like this one. I carry it in my 1800's trunk, has helped many a friend, and myself several times.

a couple years ago, my bike trailer which uses regular 15" car tires, needed to be aired up.
it took about 10 minutes, but this little thing just kept on pumping and did the job.
this is a big trailer, not a tow behind for a bike.

I think he needs instruction on how to put air in his rear shock due to an inoperative OEM compressor, not air up a tire.

You would be better off picking up a complete compressor off E Bay. Otherwise you would need to put a air stem on the compressor line. Way easier to just get a newer compressor.

I looked at the parts fiche, and there are no internal parts listed for the compressor. You need to purchase the complete compressor.

My thoughts as well.

To give an idea, you can buy and dismantle a cheap compressor and compare the pistons. Maybe it is a standard part.

Second, you can build the piston rod by yourself using a piece of aluminum and some tools. It mustn't be too difficult.

Third, you can take the broken piston to a welding shop and have the broken pieces TIG welded, then file and reshape the welding area as in the original form.

Easiest thing to do is set it up like an Interstate with a fill hose in right bag using hand/bicycle tire pump. :ugeek:

Thanks all.

Buying one of ebay isn't an option at the moment with the AUS/US dollar. While the compressor itself isn't that expensive, the postage is twice as much as the unit, bringing it up to about $160 for a **** second hand one.

I did get the old connecting rod welded, but that only lasted a few rotations. I also took apart an old compressor or two form mates looking for a similar size connecting rod and piston, but no luck there.

I recall reading some time ago the method for pumping up the rear shocks via the outlet. If I recall you had to attach the pump to the outlet and then simultaneously press a few other buttons...but this is what I can't remember. I would assume it is the outlet and increase buttons, but oyu know what happens when we assume.

Try it. Hook small compressor to air line fitting, push air button for it and the button you used to use to pump up rear shock. I forget on the 1500, but on my 1200, the buttons just controlled valves in a manifold, no reason they wouldn't work in reverse I think. As far as rear shock, you are directing air that way, but it's not from bike's compressor. Might have to have bike running in neutral?
Now you have me curious, might try it myself? You also could disconnect the bike compressor and replumb the hose to a Schrader valve for use?

Check to see if there are any salvage yards around. Not sure how popular the wing is in Australia, but you might find a compressor there.
