Remove and replace a wheel bearings without puller or press?

처리 내용

I've replaced bearings without either a puller or a press, it's perfectly doable, although a bearing insertion set does make things much easier. These are cheap and you can get them off the internet. Failing that you can do without. Bearing race removal: First you need a hammer, punch, gloves, safety glasses, a torch and a piece of scrap wood to go between the hub and whatever surface you're hammering the hub on. After removing wheel from the hub you should be able to get the seals and bearings out with basic tools (Keep the seals for the time being). Once you have those out you need to get the inner bearing races off, which is the more challenging part. To do that you heat the hub it using a torch until the bearing grease starts to drip out, then hammer the races out using the punch. There will be grooves machined out of the hub to do this, you just hammer one side, then the other until it drops. Flip and repeat for the other race (assuming you have 2). Keep the old races.
