The xray shocks are terrible. I spent a full day trying to stop the leaks .

I see people are loving the mp9 shocks
. Do I need the standoff and does xray springs fit mp9 shocks?
How much longer are they?

Anyone have part numbers for the full mp9 shock kit with velvet shock bodies ?

Where are they leaking - seals or around the cap ?
They sometimes ooze a little through the seals on the older shocks, but not to any major extent. This was easily fixed by running 2 x old O Rings on the shaft to restrict shaft travel and not over-pressurize the shock. You can also run 2 of the thin spacers between the seals instead of one to grip the shafts slightly more.
If they are leaking at the caps I would suggest you check your assembly and / or bleeding procedures. I have never heard of the X-Ray shocks leaking at the caps (except when using foam inserts that are too long), but this is a non standard enhancement.

There leaking from the cap and they were before we did the shock cap mod. The bladders are new and I tried about 20 different bladders.

Shocks are terrible full stop. I know how to bleed them

never had any leak problems with xray shocks... they are actually not a bad shock... but with the mp9 shocks, I could get more downtravel.. resulting is less bottoming out on bigger jumps.. take a look at the rear of your buggy with full droop setup.. 113 mm I believe.. then go look at mugen, kyosho... you can see a noticeable difference ... our local track has several big jumps, as well as a few of the JBRL tracks we have been traveling to... with xray shocks, if I didnt land perfectly, I would chassis slap pretty hard... now, with longer travel, this car is much smoother and more forgiving on landings...

Hi guys,

got a bit of a newbie (to rally x) question for you all,

Just picked up an 808'10 roller from eBay, I've just been rebuilding it, noticed that for some reason, the pinion gear had 3 bearings fitted.
I say had becuase one of the bearings was completely collapsed and didn't allow the pinion to touch the crown gear due to the movement.

I've put everything back together with just the two bearings fitted. But the front most bearing has huge slop in the bearing housing. I assume that with the previous bearing being damaged it was damaged the bulkhead also, but I can't really see any major marking on the bulkhead.

Is it possible that this is an older spec car that requires two different sized bearings for the pinion gear or irks ur more likely that the bulkhead is damaged..

Any help is much appreciated guys.
Thanks in advance
luke

Luke,

The kit you have is the latest version with the 3 pinion bearings upgrade, all 3 bearings should be identical and should fit perfectly into the bulkhead, if you can't fit the entire 3 bearings assembly into the bulkhead then your bulkhead might have been damaged by the failed bearing. Check the bulkhead for any sign of damage or deformation, replace where necessary...

3 pinion bearings upgrade,
Most season racer prefer to use the older 13X19 configuration bearings bulk head.

Most said it is most reliable than the current new bulk head.

The newest 2010 kits come with the 3 bearing pinion as standard ..there should be a thin (1.25mm) spacer as well...fit one bearing at the front (cvd) end of the pinion then the spacer then 2 more bearings..hang on I think the diagram is still on my desktop..I'll upload it again..

crap it's a pdf..oh well you can just download it then..

Hey Luke,
just to make sure you are clear, you cannot put it back together using 2 bearings.. that particular bulkhead requires the use of the 3 bearing setup.. all that slop you are seeing is because you tried to reassemble using only two bearings... keep in mind that there is a 3-bearing pinon and a 2-bearing pinion, so remember that if you ever go to replce pinions... I have not tried the 3 bearing setup as of yet... mainly becasue I have never had any problems at all with the 09 spec design... knock on wood

There is no problem with the Xray shocks. I have never had a leak so obviously you are doing something wrong. Make sure your O-Rings aren't damaged and make sure your bladders aren't torn.
