Whoa, why would you do that?!

What part of the shocks is coming apart? The shock body? Or the screw that holds the piston on the shock shaft?

I just got threw racing tonight and had 2 shocks come apart on me too. It was the screw on the piston unscrewing itself for some reason. I just rebuilt the shocks last night and used loctite and they came loose. The threads seem fine but I might be wrong.

It's really important to clean the screw and the inside of the shaft really well with motor spray, so the loctite will stick and hold them together.

When you put the loctite on the screw, spin the screw across your fingertip to wipe the excess off and leave loctite only in the troughs of the threads. Crank the screws down tight, just don't strip the head of the screw!

You can let the shafts sit for a few hours for extra insurance, but you shouldn't really need to wait for the loctite to dry. It's realistic to say that you could make changes at the track and they will stay together.

What grade of loctite are you using? I've been using a small dab of RED loctite and haven't had a screw back out in a long time.

Blue should be fine. Red is really permanent and you might struggle to get them apart after that.

Crimewave - Changing the shock oil shouldn't have any effect on the piston screw. Though, changing the pistons requires pulling that screw out.

Forget locktite. Use CA there's no need to take them apart. If a shock shaft bends a new screw comes with the new shock shaft. Use a Dremel tool to grind off the head of the old screw so you can reuse the piston. Problem solved. I have multiple shafts with different pistons on them and all of them are CA'd. I never have a problem.

I change my oil all the time and never had one back out. I go one step further and use an xacto to ream the hole in the piston so the screw is a slip fit. This way the piston cannot rotate and back the screw out. I feel this with the use of locktite solves this problem.

What about the limit/grub screw? If I let the shock fully extend it would cause the screw to come out. I made sure that the shock is free floating on the top mount by adjusting the grub screw and my problem to go away.

i let locktite sit 10 min and have never had one come apart.

a little thing i do is reem out the shock piston hole a bit with an exacto then stick the screw through the piston and strip it out...ie just keep turning the screw after its all the way in. then put a dab of blue locktite on the end and screw down on the shaft.

i think that people locktite the screw first then put it through the piston which wipes most of the locktite away.

lol just read two post up

yea do that

I think the losi shock on the 8ight is one of the best when the loctite holds properly.

Hey Aaron, could you suggest a shock shaft that uses a nut to hold the piston on, I think the tiny screw they used isn't the best Idea that losi's cooked up. Even if it stays on, the allen head is so small, that is can strip easily, or even break off the tip to an allen wrench.

Mugen shocks would be a bad idea, plus we'd all ridicule you for doing it!
