Progressive springs

Post by GLnewbie » Thu Oct 19, 2017 4:36 pm



Currently changing my front springs to progressive on my 83 gl1100 and I have a question I can't seem to find the answer to. Do I need to pull the a and b springs or just the b.

The progressive springs are a single spring for each side....the factory springs are two springs per side....pull them both. When I did my 83 I found that the oil was nothing more than a grey sludge...probably still the original oil. I used diesel fuel to clean them out before i put in the new ATF. You can make a tool to help put the caps back on but it's possible to put them on without one...with the springs OUT start to screw the caps on and make note of where the threads begin to catch. It will make it easier to start them under spring pressure..

Overdog has a point about putting those caps back on. I pretty much lost my religion putting mine back together after putting in the new progressives.

I laughed at this...

Slick tool. I cut off the handle from an old shovel and put a big groove in it the size of the air fitting. The first one broke, but the second one worked. Had to get the wife to push down the thing while I threaded it in. Finally got it to thread.

BTW I've started out not using any air in the shocks but I do seem to get a bit of hop on nice roads. Not sure if adding air would help. Had new tires mounted and it is possible that the balance is off. Bike does feet so much more stable with the progressives and new tires though, so the OP should like the changes.

Have found one up here in the soon to be frozen north, did the exchange and will be ordering it. Proper tool for the job is so much easier considering the time and resources for a DIY. Used a drywall dimpler for years, then decided to get a drywall screw gun - time saved paid for it. Also a little older and don't need the accident factor.

I just put the fork leg in a vice with ally jaws, then used a massive half inch drive socket with a crank handle to turn the cap whilst pushing down.
Worked a treat.

Also stuffed the socket with some cloth avoid scoring the fork cap flats.

The problem is, especially on the GL1500, good luck leaning over it, pushing a spring in 6 inches with 80 lbs of force, while trying not to cross-thread an aluminum cap with tiny fine threads that are easily ripped out. That's why I bought that tool, which makes the process simple and easy, both on and off.

Getting too old for the accident factor as well. Don't fancy having to replace the front forks either because of a small mistake. Besides, do it in a few minutes or a few hours, time is worth something. I also think that having to do oil changes every two years will pay for it in no time. Amortize $250.00 CDN over 6 years and it really is not a lot, one 24 of beer a year up here.

Cheers
