Armstrong Dampers
Dear All
Before I re-fit my dampers I'd like to get a better understanding of them....I know there are two pistons immersed in oil and each piston has a spring loaded valve ? , also a valve between the two .
Has anyone a good diagram of the workings , or even photos of the stripped units ?
Many thanks
John

Well,being a long standing Blue Peter viewer , just couldn't wait , so , out came the hacksaw....
Note the two different pistons,one ( bump) with a seal and the other ( rebound ) without , in the next post.

Re: Armstrong Dampers
last photo
P.S 2 bleed holes removed shown in black from the bottom of the cylinders to the valve
Starting to understand it now...
I think the bump and rebound springs are labelled the wrong way round...

Re: Armstrong Dampers
Was that therapeutic for you?
You really are impatient to be spending the morning cutting one open when you only asked the question last night.
Nice job though, hopefully they'll prove useful to someone else too.

Re: Armstrong Dampers
Yes, I like to get the job done....I am not long in this world.
There are on the crowns of the pistons ball valves held in place by fine coil springs , one assumes the pistons are only functional on the downwards stroke....

More to come as I get my head around them...

Re: Armstrong Dampers
Here is my version of replacing the seal, very loosely based on Declans method.

Thanks to all.
