Torker DX problem--crank slop

Yesterday, my son was riding his DX24 for the first time in a couple
weeks; the last time it had been ridden was by my buddy, who's
considerably heavier than my son, on what I'd call a black diamond
trail. Anyway, my son said noticed there was a "catch" in the cranks--a
slight sense of movement. So I rode it and felt the same thing, which
is hard to describe, but feels almost like something slips every
half-revolution or so when putting power into the cranks. So, when
first getting going, or when hitting the brakes, it's more noticeable
than when just cruising along.

Here's what I've done so far, without fixing the problem:

removed wheel from frame



removed cranks



cleaned and lubed splines and cranks



replaced wheel bearings with new ones



removed, lubed, and tightened pedal spindles



put everything back together




As I said, this hasn't fixed the problem. Any ideas about what it might
be? It's nothing that can't be lived with, but it is annoying.

Make sure the pinch bolt is sufficiently tight.



This was the diagnosis to the sound from my DX24.

grab both cranks and rock it back and forth. if you feel the slip then
it is probably the hub. ( i am thinking of what the 04kh hubs do, and
you fix it by taking the hub bolt and running it all the way in with
out the cranks on then take it out) not sure if that would work for
that though

Yeah, it's the hub's keyway, and when it gets loose it's referred to as
keyway slop. This same thing happened to a friend of mine's DX. Still
rideable, and he said after awhile he didn't even notice it anymore.

After a year and some months of riding my DX, the right crank comes
loose now. The pinchbolt on that side is also stripped, so I just had
to tighten the crankbolt after every 5-10 rides.

It might be something simple, like not having one of the crank bolts
tight enough, or not having the bearing holders tight enough.

If you can make any of those wiggle by pushing it back and forth with
your hands, it's not tight enough.

Thanks for the feedback. It's not the crank bolts, pinch bolts, or
bearing holders, as these are all tight. I can't wiggle anything with
my hands--it's all solid. It's only detectable when riding.

So I'm thinking it may be this keyway issue. Is there anything that can
be done about it? Can it be unslopped?

what you shuld do is have your son hold it up in the air and have him
spin the cranks and you shuld lay under it and see if you can see what
the problems is and see if you can fix them
