Renovating Rear Shock

[Danwarb]

Hi Guys,

I've fitted a temporary rear shock which a rusty looking one off eBay and now I'd like to get the one I removed renovated before switching it back.

Who do you know who does this and how much would I look at paying for this?

Cheers,

Dan

I found someone on ebay last year, offering a rebuild service for £210 - if you buy one from them + a deposit, then return your old one for a deposit refund.
Though to be honest, the OE one isn't that brilliant and I would consider just buying something better instead.  Threepot got what seems to a decent one for a reasonable price.

Or buy a replacement? Think I paid 239? Happy with it so far.

Whats the main use for you, and is price important?
I rebuilt mine using ATF fluid and air, with around £40 of seals etc, and it made a hugh difference, but my mileage was lowish, and only used on roads.

Hi Phil,

Yes i'd be up for doing this definitely but don't have the equipment for re-repressuring it or do I not need such tools?

I used a cheap cycle tyre pressuring kit with a cartridge. Its a tiny amount, but its getting the kit off before the tiny amount escapes again.
The cycle thing has a little valve device, so it can seal before removal, and the pressue is fine.
If your old shock  was leaking oil, the only criteria is the chrome shaft condition.
If the new seals cant seal, due to shaft wear/damage, your then looking at a more complex lob.

Hi Phil,

Your inspiring me to go for it and do this my self.

How can I work out what seals I need?

[London_Phil]

I've got a list of parts, Ill dig it out this eve and post it.l
I've posted it before, so try a search too.
I've got a dismantled shock too, so I can show you what to expect.

Some Caveats before you start

Probably easiest if you strip it 1st.
If it's fubar, then you waste nothing on parts cost.

Check the piston rod is not worn/ pitted where it runs in the seal.
Ensure you can remove the dust seal for the valve, as my valve sheared off when I tried to remove it.
Measure the compressed length of your spring, so you can set the preload back when re assembling.
I used ATF Dexron III and air on mine, lots of opinions on this, mainly howls of protest, but look, its a rear shock on a 20 yr old bike....

I used this guy for the parts. Very helpfull
