Axle Replacement

[DKEG]

I broke my front axle on the MORE ride last night, now I need to replace it. I got one coming from Spot. I figure out how to remove it (Thanks Ricky!). In doing so I removed one bearing. The other is still in there.
1. Do I need to remove the other?
2. How do I install the new one
3. Mainly how & what do I use to press the bearings on with?

I know a little bit about bike repair and want to do it myself. Any info will help?

I can get the bearing out, But what do you use to press the bearings on to the new axle or into the hub. I guess when I get the new axle it may be clearer for me.

One way to do it is with a tool that will act like a mini headset press. Some people (Peter?) have said that they have the King bearing tool that you use to put bearings back into the King hub. I think it may work on your hub as well. It's on page 15 of the manual above.

Another way is to drive it in using a hammer, SLOWLY! Basically, you have to use something with a flat surface that is bigger than the bearing itself so that the load is spread evenly betwixt the inner and outer race. They make tools if you want to use this method. I'll see if I can dig up a pic.

I have used screwdrivers in a pinch. I'd feed the bearing onto the screwdriver, feed both into the hub, check for alignment, then slowly tap the end of the screwdriver while carefully checking to make sure that it's being driven straight in.

I have used a long deck bolt I bought from home depot with a couple of washers and nut.

Make sure the washers match the diameter fo your bearing, put one one each side so they press evenly against them then tightend the nut slowly onto the bolt. The force of the tightening and the equal pressure excerted by the washers on the bearings should drive them into the hub straight and evenly.

The key here is to take your time and be patient so that they go in straight.

I've also used this method to press headset cups into my head tube...

So this "tool" can be easily made for a couple of bucks at your Home Depot. It'll act like a bearing press. Just make sure that it's all going in straight.

I used a set of hub bearing tools from Ringle when I worked at a shop ten years ago, but I have never run into a pic of it on the web. It was the easiest setup and very fast and precise. It had a hub support thingy, and two punches with nubs in the center. Anyways, back to work... :D

Thanks Again for the info. David

What kind of hub is it?

For pressing needle bearings into my frame once I used a large c-clamp and 2 peices of wood. One peice on either side of the frame(in this case the hub). I carefully placed the bearing into the frame/hub as straight as can be, placed the other peice of wood on top of the bearing to pretect the race and slowly tightened down on the c-clamp. It went right in, no problem. it's worth a try, other than that, take it to a shop, they can do it with a headset press.


Hope that helps--Graham
