RPM true track pivot balls keep pop out
 

Need help to solve my problem with the pivot balls keep pop out of my RPM true track.

Sounds like you stripped the arm. I have heard of the pivot ball pulling out of the axle carrier but not the arm. If you stripped I'd get a new arm.

Thanks mkrusedc it's the "ball pulling out of the axle carrier", sorry

Yup - Thats why i binned RPM Knuckles!

binned? not following

Maybe trash "bin"? Or parts "bin"?

Just for you...

Those Tekno axle carriers are the best.

Or you could use a set screw to keep them in, like Mistercrash did on his ERBE.

You can get the Platinum Revo knuckles. The have a retention ring built in to them or you can cut a piece of brass tubing and make a retention ring yourself.

(If this was covered in the links posted above sorry I was lazy and did not feel like checking)

Okey but It is the true track RPM (rear) I have problem with, is there a solution for this?

Make your own retention ring from a piece of brass/bronze tubing. A dremel tool and about five minutes should do it.

This is what was suggested in the earlier post by mkrusedc.

Thats nice, but you're from NJ, most comments in the link are European.

He is British though! Like linc but without all the weird cross-dressing stuff.

He should have picked up Jersey talk by now...

In NJ 4 yrs now and only on a temp work visa - You need a green card to talk Jersey...

LOL!, But 4yrs sounds a little more than temporary to me...

Actually 4 yrs is this Sep - I get up to 6yrs before I booted...

Here is the thread. He used copper tubing to make a retention ring on the axle carrier.

That looks spiffy... I also like the traxxas parts that have the steel rings built in!

but he's trying to fix an RPM part, so you guys are all way off. Last I checked RPM has a lifetime warranty, and I haven't heard of this problem before. E-mail RPM..................

Chris- thanks for the link. Now speak american like the rest of us a-holes!:lol:

In the Rpm hub ball ends tend to pop out more than the factory hubs. At least that is what I have read and experienced.

And sod of Harold, leave Chris alone, you bugger.

Thanks guys, as lincpimp says "the Rpm hub ball ends tend to pop out more than the factory hubs". It's because of the softer plastic material.

I need to see if this will work

Thanks:wink:
