re-shock pre-load

[smartiedarkblue]

hi all, just wondering, on the rear shock remote preload adjuster, can this be removed and then put back at a later date with no problems,

Is it pressure locked with the shock and if removed will the pressure in the shock be released.

i am unsure how these work. any advice would be great, its just there is one on ebay that i am interested in but if there is no gas pressure in it then whats the point???

cheers

I've just had a look at both of mine, they're identical.

The adjuster is connected to the body of the shock with an hydraulic hose fitted with "banjo" bolts, just as on a brake line.

I guess you can disconnect very easily, but I cannot see how you refit, refill and bleed the system.

I would put this down to specialist repair work and leave it to an expert.

Does the eBay advert say there is no pressure?

I'd be more concerned that the damper works - that is a specialist repair.

The Spring Load is largely personal preference, especially if you ride one up and no luggage. I think you would be able to manage OK on the softest setting and the MOT would not be bothered. However, if the damping doesn't work - that's an MOT fail

CAUTION! the pre-load collar AND the hose AND the adjustable reservoir all contain high-pressure gas! by winding the reservoir-cap gently from low to high, the mainzpring should compress by about 18mm. to remove the collar, use the strongest claw-spring-compressors you can fit to shorten the mainspring by 25mm
there is a circlip round the main telezcopic body, revealed by pushing the pre-loader down.
forgive me for repeating, but beware the spring and gas energy! Consider using strong wire t several points to tie the spring coils, (many coils of wire!!) AS WELL AS the spring-compressors. if in ANY DOUBT the risks of injury would cost a professional many hundreds a year to insure.....

PS I've seen the damage accidentally releasing a similar spring can do. very memorable.....

I must apologise for mis-information, re the "Showa" spring-damper used on the NTV. Yesterday I learned from Malcolm at Falcon shock-absorbers of Wareham that the preloader collar contains hydraulic oil. thus once the collar is removed from the rest of the spring-damper unit, it will no longer be under pressure, (from the main spring) Please forgive the error. hope I did not cause any inconvenience.

Hardly an error Ex925, we're all a little wiser now

Smartie - conclusion is clearly "leave it to the professionals". There are several companies that can do an overall / rebuild. I had a price from one that indicates £70 as starting point for working on one.

When I got my revere I assumed the rear shock was stuffed, but having compared it to McF's spare I centred all the settings and it has been fine since.

An overhall would improve it, but its only an issue when I play. I just have to think about it more.
