I thought id do a quick reference of how to assemble a losi crawler shock incase some of the new guys need a visual reference...

all the parts....(although i will be using traxxas rod ends)

you can start off buy putting the rod end on, like i said i chose traxxas rod ends instead of the ones included.

If you put the rod end on first make sure to put the shock cartrige on next, follow by a c clip, the piston, then another c clip.

now, you need to choose what oil to use. I'm using 65 wt but its a little thick for the holes on the piston, you might just use a lighter oil or drill out the piston holes a bit. since i didnt drill the holes out and all i had was 65 wt i only am running about or a little less than half full.

now put the shock housing and shaft assembly together...

next you need to screw on the adjuster nut onto the shock body.

add your spring, along with the spring cup ant the bottom, kinda push it down over the rod end and you are done.

Those Losi Crawler shocks look pretty much exactly the same as the threaded Losi xxx-nt shocks, or the Dynamite/Losi T-Maxx shocks

Also, I would not run any shock only half full, that means it is also half full of air, and the piston will come completely out of the oil at some point, and it will hurt the shock performance. Personally I would use a lighter weight oil, or drill out the holes in the piston.

yeah i agree for the most part with you on that Joe, I'm picking up some lighter oil today for that reason but since i was in a hurry to get these built i used what i had and didnt drill the piston. although I'm not saying what you said is wrong i think on a crawler where the suspension isnt moving at a really rapid speed its gonna be easier for the oil to make its way through the piston without a problem.
 
Nice tutorial there Lloyd, I built mine a little differently then you did but ended up with the same results, LOL!!!!! also one thing to remember with these shocks is the mounting hardware is not drilled for 3MM screws so if you do like Lloyd and myself as well did you just use the traxxas rod ends and drill out the little black mount for the other side to fit a 3MM screw that way you don't have to use fuel tubing to mount your shocks....

damn, i knew i was forgetting something lol...but yeah exactly was curtis said, and its super duper easy to drill out, no biggy at all.

I forgot some thing else, you don't have to do this but I highly recomend it, Before you put your shock shaft through the o-ring cartrige. I recomend you put a couple of drops of shock oil in the opening of the cartrige so you have less chance of ripping you o-rings which means less chance of them leaking real bad, it will also make the shock shaft a lot easier to slide through the o-ring cartrige.:D
 
yep, well put man.
 
Losi's crawler shocks rule. I run them on my Axial/HR with the HR chassis plates. Just a heads up, though, if you live in an all-metric world with no 4-40 stock they *can* be a pain to fit. I used Axial's ball-joint ends at the bottom of mine (they fitted, just about) and had to cook up something at the top using fuel tube, metal ball-joint inserts and basmati rice. They do work very well though.
 
I just drilled out the standoffs the shocks came with to fit the mounting screw and it worked fine.

Hey Webbage you are right about the 4-40 stuff, it really doesn't make since when most all crawlers use metric hardware, if you read through the whole post you will see that Lloyd and I addressed that issue by using Traxxas rod ends on the shock shaft and drilling out the plastic mount for the top of the shock so it would except a 3MM screw which will give you a more solidly mounted shock then using fuel tubing.:D
 
^^^yep...and just like in Robmob's pic...easier to drill out the piece for the top then to go crazy trying to figure something else out that will be sturdy and stable.
 
Nice write up SNG, thanks for sharing. I have a question....is it normal for the Losi shocks to leak slightly? I notice a build up at the bottom shaft, I wipe it off and bang it's there a day later.
 
Unfortitnetly it does seem to be the norm, I have mine mounted upside down and they still leak a little....
