Basic 'servicing'.

1) take off suspension. use a heat gun to take off the bolt on the bottom and use an impact gun.



2) yank out the insert and bump stop


3) clean out old grease, inspect bushings (yes, mine need to be replaced)
Also clean out the seal...




4) put in new grease between bushings (I used a big ass flat head screwdriver as a long putty knife)

Advice like this, from people who do stuff, is so much more useful that people who know stuff... Kinda like when one of my dipshit LeMons teammates dropped our free turbo and bend the compressor wheel, rendering it, we thought, completely useless. One of the other team members, a former turbo engineer said "don't worry, just bend the blades back with some pliers. Mass is conserved, balance is fine, used to do it all the time..."

So, just so this wisdom is actually useful, what part are you bending on these motocross forks? The (small) shaft, or the (big) body?

so I serviced these this weekend (re-greased only) and got rid of that nasty rubbing. Rides much nicer as well.

However, one of my inserts is done. Makes a funny sound when compressing it, and it wasn't smooth at all (when pulled apart). Also, when fully compressed, instead of stopping, it kept going in and actually started leaking nitrogen...scared the hell out of me!

So no options but to buy a new one? Anyone rebuild these inserts?

Don there's some chance that Dave Clark might have some used ones kicking around.

My 50mm stuff is dimensionall interchangable with the DMS Stuff, same threads , same seals, but different bottom fixing and length of body and of course my mounting ears are 3/16". So maybe 2 bodies and you'd be set.

Try Dave and if that strikes out, try me.

As anybody who ever talks to me will assure you, I'm not the monster as portrayed by many on SS.com

I don't have a nice vernier caliper, but eyeballing it with a tape measure, it appears the spring's ID is 7cm (+/- 5% eyeball error rate)

2 rebuild kits on the way from Odi, we'll see how this goes: could be fun learning experience, could quickly turn into a nightmare learning experience.

This is true. DMS springs (actually made by King springs in Australia) can be thought of and compared to as a normal linear spring. The taper portions are designed to act as a tender spring and are completely taken up at static ride height.

As for spring rate markings, they will be laser etched on one of the middle coils but if the springs have suffered a lot of stone chipping the powder coating may be worn away and make it very difficult to read. However, if you have a Subaru then you probably have 225lb/in front and 180lb/in rear spring rates. If you think it's higher than that then measure the diameter of the wire of one of the middle coils and I can tell you whether you have the normal spring rate or not. More likely the stiff ride (other than that's how they normally ride) is from struts that are badly overdue for service/regreasing and possibly bushings. If you hear a "gurgling" sound when you compress the strut you could have water in the housing and it needs to be serviced immediately. If the gurgling is coming from the insert itself then it is bad and needs to be rebuilt.]]> Doivi Clarkinen Construction Zone Mon, 11 Aug 2008 17:36:15 -0500 https://www.rallyanarchy.com/phorum/read.php?5,17645,18012#msg-18012 https://www.rallyanarchy.com/phorum/read.php?5,17645,18012#msg-18012
I almost never see any space between the thinner coils when they're normally compressed.

Oh, and I wasn't promoting DMS springs up above, just imparting the info I got from DMS.

Except looking at most DMS springs they are clearly a taper ground wire or a true progressive spring.

Now i say if you're aren't Progressive, you're reactionary, but when not discussing politics I prefer to avoid progressives if I can because of the difficulty in a) accurate rate call-out (Ford rates their springs in three rates when they do progressives: initial-mid stroke and near full bump) and the non linear way they act when putzing with ride height.

The major reason I don't like DMSs springs is replacements cost a million dollars each.

Very bouncy on the high way (over sprung?) but when I had 11 cases of motor oil in my backseat and trunk, it was a much nicer ride.
