Hyper 7 Hex removal- the pin is stuck!

[vibrating_cake]

As the title suggests, I'm having trouble removing the hexes from my hyper 7, the problem is the pin that goes through the hex is stuck in completely on 3/4 of the hubs. One hub i can get the pin out, to remove the hex and its thread, but the other 3 just won't budge!
Any ideas on this?

I'm going to try soaking them in wd-40 overnight but other than that i'm stuck, i've tried driving a small (broken) screwdriver into the holes to push the pins out that way, but because it spins you can't really get a good shove on them, even when one person holds the hex and the other whacks the driver.

It's a minor detail, but one of my wheel bearings is squeeking so i'd like to inspect it and re-grease it but i can't with the hexes stuck on .

Daft question, but have you removed the locking screw that goes down the centre of the driveshaft? Not sure if this is standard, but they're on my Hyper 7. Needs a 5mm hex IIRC.

 

Only option really is to stick them in a vice (or locking pliers), and tap them out with a screw driver/drill bit and a hammer.

I had this too. If they are the stock silver hexes, I had to wd40 and knock them out with a small screw driver. Was a PITA. They don't have locking screws on the stock ones, but the hexes are pretty soft, and it looks like the pin munches away at the insides.

Bah humbug!

I'll have a look for a hex on the middle, if not it looks like it's going in a vice!

It's a hyper 7.5 technically, so it may have the hexes, i'll have another poke around when i get home from work

I got my Hyper 7 as a second hand roller with some hop-ups, so not sure what is stock and what isn't. Mine has the locking screws, and it threw me the first time I had to take them off, that's why I mentioned it.

I made that mistake some time ago. Fought for ages with the pin only to realise there was an unseen grub screw also in the fight.

Can honestly say I never done that before......... .........

Oooh look at you, mr perfect......... wait a minute I'll find you a medal

^lol

Took me a while before I found the grub screw

[Smoothybb]

I think it's the cvd's that have the grub screw but not 100%.

[shdaxner]

Dont they all have a grub screw in the end? otherwise how would the pin stay in?

Both my tq's have them in not sure about the other models

Held in place by the wheel

A stupid design, IMHO, a simple grub screw makes so much sense.

Normally a decent fit so push in, am sure I remember putting some in horizontal on a 1/10 cos they kept falling out.

[shdaxner]

Really? so when you remove the wheel nut the wheel comes off the pin drops out and the hub is off straight away? or am I missing something?

[Noj]

On a new item, then the pin should be a snug fit...add a few miles and some wear and tear and yes, that can happen... My ST, in remarkable condition and never used hard, has this exact issue on two of the axles....both rears, as it happens.

[ExLimeyBasher]

Both the Universal joint type and the CVD type have an  M5x5mm long Grub screw to hold the pin in. Hobao and Ofna.

So there it is, silly old bones and cups get no grub, smart arsed cvd's do

[Smoothybb]

Well that's made my mind up, never using a cup ever again, they's stooopid.

[Noj]

Not even when playing cricket?? Bravery indeed sir!

[vibrating_cake]

Well this thread deviated well. Lol.

I have bones and cups on one axle, i know that much! I might have a look before work today if I get my arse out of bed early enough!.

Also I wouldn't wear a cup playing cricket, I wouldn't play cricket, anyway we said there's no screw if you use a cup, I'd also rather screw, so it's decided. 

[vibrating_cake]

3mm hexes in both bones and cups and the other ones cvd's?

[Smoothybb]

Cups bad, cricket bad, screwing good and we should have grub screws in our bones as well?

I'm lost.

[Noj]

Get that man a map!! 

[Anthoop]

I have never seen a Hyper7 without the allen screw in the end....no matter which shaft.
