I just got this rear shock back from a local shop , they replaced the seals , oil , nitrogen. I put it on and tried to start her up and after about 3 kicks this is what happened ! It blew out and oil went everywhere , shot all the way across my garage. Did they do something wrong at the shop ?

looks like they forgot to install a shap ring on the outside of the piston. Take it back and have then fill it with oil and more nitrogen. it should be covered under faulty workmanship...good thing it didnt happen out in bfe on the trail...Sandman :roll:
-
I believe sandman is right on, the snap ring may have been faulty,buggard,not properly installed etc.
I hope the shop stands by their work.

OK , Thanks guys. I will have to take it off and swing by there monday , sux because today was a perfect day to go riding.

Theres no clip. It threads in. to remove it from the shock you have to drill the ping marks out so that way when you unscrew it, it does not destroy the threads. It looks like to me from way over here that they just unscrewed it. I would say they screwed your shock up royal.
-
Did they have to remove this to put new seals and oil in the shock ? it was not like this when i dropped it off to them.
-
I believe the resivoir is what 98 is refering to blowing out. Am I mistaken?
Pics to follow.

Yes, to rebuild the shock you have to take the whole thing appart. You start by drilling out the ping marks that are done at the factory to keep it from unscrewing. If you do not drill the ping marks it will destroy the threads when you unscrew the vavle from the shock body. Also when that blew out like that it popped the the rubber nitrogen bladder,you will need a new one. If I was you I would just start looking for a new shock.You can see the ping marks I'm talking about on the right and left of the hole.

:-o

The bottom of the reserve didnt blow out tho , The bolt that screws into the top of the reserve busted out. Can you guys see the pics off the links i posted ? If not i will try to post pictures or a different link to the pictures. I didn't have the shock rebuilt , i had them replace the seals , oil , and charge it. I am going to make the shop that did this either replace the shock or fix the damage done.
-
From what I see, BDI is right, the stake spots were not drilled out and the threads are damaged. An experienced shock rebuilder would have seen that and known it would not stay sealed. I think BDI's plan to just find a used shock and start over, is also the fastest way to get back out riding. No reason to get mad or make accusations, just decide on the fastest way to get it fixed and focus on that. Your shock rebuilder will probably help in this process, if you dont piss him off.
Happy Easter, hope your bike is back together soon.

if your just going to replace the head seals or assembly there no reason to remove the compression valve unless it was leaking or something was damaged
and leaving the valving as is I just took a look at my 500 shock i had scotts revalve it and looks like its never been removed ask them if they removed it if so why
-
If your going to rebuild something properly you need to take it completely appart and replace every part that can go bad, that includes the o-rings in the valve. if some one only half ass rebuilt your shock you would be pisst if in a year you have to do it again because the o-rings they didn't replace started leaking.
-
I agree if i asked a guy to overhaul it i would expect it to be done right if i asked to have a seal changed and recharged i would not expect any more now when a fork seal go's bad i don't totally disassemble every part of the fork leg sometime it best to leave some things alone
all that maters is the shop makes good on his shock
-
I thought having seals replaced was just general maintenance , this shop has been around along time . I'm sure they have replaced many seals in the years they have been open. The shock was leaking oil from the bottom of the shaft , i'm not sure what seal was bad. I know i started the bike and road it many times before i had them service the shock and if that was going to blow out it would of happened when riding it ( jumping around and what not ). They had to take this apart, that could only explain why it would blow just a few kicks on the bike. How they damaged the thread and why they would try to put it back together after it was damaged is beyond me. I am taking it in Monday after work , I'll hand it to them and say " Call me when it's fixed " :-)
Thanks

I wonder if they could have over charged it. I know that with my nitrogen set up I can easily put 500 psi in something with out breaking a sweet. I myself would never do a half ass job of rebuilding a shock even if the customer asked me to. When you work on something for someone and then there is a problem with it no one ever says bdi fixed it and then it failed because I asked him to half ass it. My reputation is worth to much to me. if some one wants hack work done I will turn the work away. I just turned down a complete engine rebuild because the guy didn't want to put in new main bearings. anything worth doing is worth doing right and if you do it right the first time you don't have to do it again.
-
Its funny BDI mentions it may have been overcharged as the first thing that came to mind when I read this was that it probably had too much nitrogen in it. Not quite enough to blow the bladder initially, but I'd imagine it will need replaced also.
-
I am sure they will stand behind their work , i hope anyways. :| I tried to take a picture of the threads , it's like they are gone. They are all smashed together and smooth on the parts that launched out when i tried to kick start it. I added links to the pictures , I hope i get my shock back by next weekend because i have a trip planned.

ya they unscrewed it with out drilling the ping marks.
-
Shop is standing behind their work and told me they were sorry. :-) Also said they would try to have my shock back together and back to me tomorrow. :-D I have done alot of business with this shop in the past years. I own a few quads , k5 , and a wr500 so i have dropped thousands in the last years going there. Thanks alot for all your support guys ! :wink:
-
That's interesting. I wonder how they could possibly fix that correctly by tomarrow.?
-
I'm sure it will take longer , atleast a couple of days. Although he told me they have bladders and valves in stock. So who knows , same place told me a week on a bore on my wr500 cylinder and had it done in 3 days and then told me they were waiting on the piston that's why it took so long . We will see i guess :|
-
if they have the parts in stock and the threads in the shock body are ok then I guess it would be easy to fix by tomarrow. Did you look at the threads in the shock? are they ok?
-
OK , Now the shop isn't standing behind there work . Said they didn't remove the valve when they put seals , oil , and nitrogen into the shock. Told me the bladder is blown and it was going to be about 2 weeks and 70 bucks for that but then tell me the valve threads are ruined and they can't find a valve for it. They are trying to tell me the bladder blew and thats what caused the valve to shoot out , i blew a bladder trying to kick start it ? ? So now what ? ? ? grrrr.. So i called a dealership and told them exactly what i have said in this thread and they say to do that job correctly you need to take that valve out. Said " sounds fishy to them " :x
-
Perhaps you can find a used one and get out riding soon. There were a lot of KX500's made, so you should be able to pick one up at a reasonable price.
John
-
So your saying if you drop something off to get rebuilt and you get charged for that rebuild. The item that you just installed that was just rebuilt just took a poop on you with zero hours on it , you would just look for a different or new one ? Not question the shop that just did the rebuild ? Wow , lol . . . . Can i rebuild some stuff for you then ? lol
-
i hope you name names.

Well the response you now have is the one I expected you to get in the first place. I think most of us have been screwed by a shop and realise how little chance you have of ever getting anything out of them. Your energy would be better spent finding a new shock. By the way the blader blew because the valve came out not the other way around. You are dealing with jack asses.
-
The shock was over filled with oil. The bladder was not inflated, it was collapsed when they were filling it with oil. I have seen this happen before. My two cents.

And that is the reason I learn how to fix everything on my own. Businesses like that piss me off and make me not trust any of them. Sorry to hear about this bad situation. Wish I had a spare shock laying around for ya. I will keep an eye out though.
-
Well i talked to PR racing Of Toledo,Ohio again and they said if i can find a junk shock one that needs rebuilt on ebay they will take the bladder and valve off that and fix my shock. They also said you can not buy valves for them , a bladder is oem part and will take 2-3 weeks to get. That's what they are telling me anyways , Will the bladder and valve be interchangable from 88-04 ? I have a 98 ( hence the name )
Thanks
-
Well , i hope this works . I just picked up a leaking shock off ebay , it is off a 93 kx500. I only paid 5 bucks for it , i hope the valve and bladder will work on my 98 shock.

if it was me I'd swap over all the parts from your old shock in to the E:bay body and leave the valve in it if is not broke don't fix it looks like the same shock good luck
-
That's exactly what they are going to do , they are going to use the top half of the shock. The bottom mount on the ebay shock was broke then welded back together , That's why they are going to use the top.
