Spring is for(k) Springs !

Recommended Posts

Hello peeps,   

Wondering who's got some knowledge to share...

took apart the forks to change seals and fill on my new to me and new to be running again SWM 320

first off one tube had the white end bit inside and the other had it outside (see pic)

I assume they should both be inside after looking and seeing damage on the white plastic end bit (may still work)

Not sure if it was assebled wrong or slipped past the snap ring somehow.

 

next I noticed the springs are not the same length.....

 

does anyone know how I should proceed?

thanks lotsIMG_3893.thumb.JPG.d3104e8340ae956994f29aa86d9b2d2d.JPGIMG_3897.thumb.JPG.9761dae68e6433e46e916517c7f93b61.JPG

What diameter are they ?  Every Swm I've seen has either betor or marzzocci forks, I'm pretty sure these arnt original.

I’ll go measure but they came out of the swm stems

Externals look standard, be interested to hear if internals are ?

My main issue seems to be the fact that the small springs (which control damping?)

are different lengths. 
so when I put everything together and start to compress the big springs they are not at the same starting point. 
but maybe it’s not a huge deal?

Don’t know.

The small spring is usually a "top out" spring. This can also be controlled by thickness and quantity of oil.  "My" solution would be put in a longer spacer to compensated, and see if it works ?

Ok.  Thanks. 
ive learned the short one is the correct one so I’ll just cut the longer one down a bit. 
 

are the plastic bits at the end secured inside the tube by the snap ring or outside the tube ?

In this pic which way  is correct ?

That plastic bit should be inside the tube behind the snap ring. The right side tube in your photo is the correct setup

 Ill just trim the top out spring on the one that is twice the length 🤦‍♂️ (dont know why anyone would do that buuut.....) and I should be on my way .... Hopefully ha ha

Mmmh, these plastic stuff is weird, it should be made out two pieces:

an outer bush and an inner one that will fit inside?

See here:

I would be careful by cutting of a part of the spring you might get much different sag which then might not be in accordance with the weight of the bike and you anymore?

Hey man 

ya mine has the inner and outer plastic. 
you can see it in the first pic on this thread 

but I don’t however have the spacers you have top of the large spring. 
 

if I trim the small spring it’s only to make the two sides the same length. 
martin told me the one that’s original is the short one so someone put in a short spring on one side that is longer than the original. 
hope it works  

if not I’ll have to source some new parts or used forks
