cvd problem

[rustlerrevo]

i just installed my new cvds and the shaft slid outta the cups twice today has any body else had this problem i have rpm arms with stock carriers is there a way to fix this

[lubecakes]

You need to screw your pillow balls in further.

[rustlerrevo]

they are just about all the way in ill do it some more and try again tomorrow

Are they Traxxas CVD's? If I recall they do make deeper cups.

[lubecakes]

Yeah they do make deeper cups. Unfortunately the rpm arms are very flexible and can still cause the shafts to pop out occaisionally. Cvds to the wheels are one of those un-necessary revo items I learned about the hard way. They do look cool though

[rustlerrevo]

Yes traxxas cvds and the only reason I got em was I kept breaking the joint part are these really no good and do the deeper cups help from letting them come apart

[Snook Man]

If running rpm arms you will want the extended drive cups.

[humayrayakongkinaon]

ever considered running the summit axles?

[rustlerrevo]

No are the summit ones better and what is the part number for the extended cups

[kgombe1]

the extended cups are for use with the traxxas lay back arms... not sure if they still make these..

Part #5153R
While they are made for the adjustable wheelbase arms, they work great for other mods/fixes as well.
