Drive Pins for KO Hubs

[JonnyPlus2]

Hi,
I want to install the drive pins in my NOS Elan +2 rear hub. I stuck the hub in the oven at 300 for about an hour but it was still too tight to pound the pins into it. I have two questions:

1) Do the pins drive in from the back or the front of the hub? It looks to me as though you could get them started much easier by driving them in from the back.
2) Should I heat the hub up with a torch? Maybe until it's red hot but *not* hotter.

As always, any suggestions, advice etc. etc. will be much appreciated. Thanks in advance.

Best regards,
Jon

If they are the same pins that I'm thinking of,one just splits the hub,place them in the groove and replace the hub?

Hi John,
Thanks.

I'm referring to the 5 pins that transfer power from the hub to the wheel.

Jon, I fitted mine from the rear. Not that much heat on the hub but also froze the pins before inserting.

Hi Kev,
Thanks for this. It's reassuring to know that inserting from the rear will work.
Best regards,

I did also Jon.
I squeezed them in using a "G" clamp, a short round piece of steel as a pusher, and an appropriate sized socket for the pin to come thru the hub and into.
Went in relatively easily, and since they were done 25 years ago only a couple have moved back into the hub a little. Another squeeze and they are fine.

I certainly wouldn't get a hammer out as you don't want any cracks, or bits falling off......

Thanks for this clever idea. It is much appreciated. Why bash on it in when you can press it in with a handy G-clamp.
