I am attempting to replace the Ball Bearings in a (really rusty ugly packed with girt) Front Hub. I am looking for paticipants experiences and what tools you have fabricated to Pull or Push the Inner Bearings out.
I can see the two "slots" but am unable to get a punch in place and deliver enough UMPH to get them to budge. I have already removed the outer bearings with a punch and a hammer (Thanks RDR - Yes it was the one you bought me at Sycamore Steam Show - inside joke).
I do have a large press but not a way to push securely in the right plane.
I am surely not the first one to encounter this, but I could not find any information in a Forum Search.
I place the hub in a vise and put the slots hoizonal. Then use a long drift or a 3/8 piece of rod and alternatly tap on each side at the back of the ball bearing cup. It is sometimes slow,but eventually it will start to move .
P.S. Chuck,don't use the felt seal with modern dirt seals.
OK I beat and beat and beat - cant get the thing to budge.
Has anyone built up something to fit in the slots that will allow you to press them out??
Thanks for the advice Jack, I have the modern seals on my 26 RrPu and they work well, I am going to have to order a set to put on these hubs.
Try a little heat on the backside of hub?
If you have access to an arc welder, run a bead around the inside of the race, then let it cool. This will shrink the race and make it easier to tap out. I have even seen them fall out when they cool down. Jim
If the race is NG and you don't want to save it, run a bead part way around the face of it with the arc welder. Let it cool and then remove it.
The two slots in my early hub ('13/'14) are part of the hub and don't come out. However, I'm not sure what year you are talking about. If you put a roller inner bearing cup up to the hub does it fit? I put rollers in mine and the inner cup was the dickens to get all the way seated.
Also, the neoprene seals were too small for the hubs and I put the Prudden seals back in with new felt seals. You may also need a thin washer where the nut tightens so you can get the cotter in the '13/'14 hub.
Just what I did,
These are three tools that I have used - each with some success.
The one on the bottom is a modified brake adjustment spoon. The middle is a modified sheet metal cutter for an air tool. The top is a modified pry bar.
I took a old screwdriver with the shaft running through a wooden handle. I bent the blade end & ground it down a little to get on the race edge. I also sanded the side off of the wood handle to clear the hub. I took out several inner & outer races with good sucess. Nelson
You can just heat the race with a torch a couple times and let it cool and it should knock out.
Some can be a booger after they have spun in the hub.
The section of race avaliable for beating on between those notches aint big,so I would suggjest doing something else before they chip off and are harder to get out.
I have took a Dremel Tool with a cutter disc on it and cut a groove in the race to cut it in 2 basicly.Easy to knock out then.
