Hi All

 

My latest dumb thing, lol.

 

So decided to refurb my lever arms at home.

 

Stripped them down and flushed them out, read up abit (thanks Ed@Bullfire) and it all looked simple enough.

 

My internals matched Ed's, so i got some O rings courtesy of Litespud (thanks again) and came to pop the new rings and new oil in and, doh, my end pluggy things don't match each other? (See pic) One has an O ring in a slot opposite end to the thread the other , nowt.

 

So the question is

 

1. Why? diff lever arms from a diff year after replacement?

2. How can i tell, codes etc?

3. Most importantly, err does it matter? Hoping not and am gonna carry on.

 

But it would be nice to know if they are diff but should be matched.

 

Cheers

 

Keith

Hi Keith,

I`ve just done both mine and spookily they were the same as yours, one with the upper o ring and one without.

 

Found some info somewhere that said that the valve without the o ring was a later version.

 

After filling with oil and reinstalling both work perfectly well with the same amount of rebound on each.

Thanks for the reply.

 

I'd kind of hoped that would be the case so i'll be plodding on.

 

Cheers

I've the same or a similar question.

 

Also just about to refill with oil and could do with knowing the expected capacity or exactly how full they should be.

 

I've watched and read a few things and there seem to be a number of ways of going about the refil. From the top with the cover off, from the spring and valve or topping off from the access nut on the top.

 

So the question is should we fill, then cycle the lever the expel any air then top off to 100% full (IE no air) from that top fill nut?

 

If so roughly how much oil will i need?

 

I went for Penrite Shocker oil No1 as No2 was described as for "Fast Road or Track Use" and got 500ml, which hopefully will be enought, less the bit I used to help with the flushing process.

 

Cheers

Yep thanks, i had come across that and a couple of other vague-ish things but was looking for some kind of definitive "Armstrong" manual for capacity or topping up.

 

But if thats the accepted norm from someone who does know his stuff thats what i'll be doing.

 

So i'll crack on and get them back on.

 

Cheers

Interesting issue. I can't seem to get rid of all the air in the bottom shocker chamber. the more i try and purge the air out, the more bubbles i seem to be getting. I filled the lower chamber first, then the upper chamber up to the thread level on the top.

I decided to open up the bottom and see if there is any air left, and to my surprise every stroke of the lever arm creates a large number of tiny bubbles. what am i doing wrong? steve.

I mounted the shock sideways in a vice with the top cap and filler plug in place. Then removed the valve assembly. Filled that cavity with oil, and exercised the lever arm. Repeat until no more bubbles. Replace valve, then with shock upright, top it off through the filler plug.

i have removed the big threaded nut with the valve assembly on it.

I could be that you suck in air via the big plug.

Hi All

Not sure what happened there i thought i'd replied to this the other day, doh.

But maybe i posted my lever arms response against another thread, that'll be comfusing.

Kind of did it as per Ed's post, filling the valve cavity first then cycled it a few times, popped the valve back in, reasonably tight as it needs to be airtight as Waldi says. But then i took the top off and filled the body to within 3/8th of the top, then cycled until no fluid drop or visible bubbles.

Hopefully all will be ok.

 

Popped them back on the other day, see pick.

 

And yes i know my trailing arm bump stop is missing, photo's and fitting it in wrong order.

 

Cheers

I’m late to this thread - when I overhauled my shocks, I also found mismatched valves. I contacted Apple Hydraulics, from whom I’d brought the shock ~6 years ago, and was told that valves had undergone some evolution at one point, but that the two versions were functionally the same. The only caveat was that each valve had to remain matched with its shock, as the valve receptacle had also evolved with the valves. By the time I found this out, the stripped down shocks had been sitting on my workbench for several days, and I could no longer be sure which valve belonged with which shock. Fortunately, one valve had a flange around the hex head, and the other didn’t, so I was able to match up the flangeless one with the hex-shaped “paint shadow” resulting from the shocks having been painted after the valves had been installed
