bearing and seal replacement questions for 2005 Scrambler 500

[p5200]

Hello, what is the best method for installing bearings into their race? I've set one in place and tapped it down until it was metal on metal. Is that sufficient? Surely it's not supposed to go into the race until flush? Also. does the coil spring on the seal go into carrier bearing housing not facing out? Thanks! 🙂 Seal goes in until flush correct?

Yeah the bearings will go in till they come up against a lip. The seal does have the side with the spring facing inwards.

Not sure how far in the seal go but you should be able to see where they ran on the old shaft. If the axle shaft has damage where the seal runs, it's ok to position the seal slightly further in or out so the new one runs on a good surface.

The method I use it a hammer and then a punch. Hold the bearing down on the housing and then tap lightly all around the outer bearing race with a hammer. For those axle bearings you don't tap on the inner race, because it will cause the balls to damage the races. If it was a bearing on a shaft though, they you would use a punch and tap on the inner race.

Ok thanks Mech, I'll see if I can get them in there! 👍

I usually use a small hammer to get the races started in and once in the hole get a piece of iron pipe or socket the right diameter to push it to the correct position, you can hear when it gets there the sound will be different. I have used a punch but feel it goes in evenly with something of the right diameter.

Yeah a socket's good because you can tap it in the center, but if you have to tap around the sides then it's much of a muchness. 

One of the old bearing cones would probably be ok to use in this case, as long as it doesn't get stuck in the housing..  haha. Tap it in the same way it was originally and you'll be able to use a punch again to get it back out.

If you are using a punch to tap the new cup in, use a small diameter one that doesn't touch the inside where the rollers go, just use it out on the outside edge of the cup.

Well, it's all back together. My only concern is, I hope I got the clip on the chain link fully. With my failing eyesight I don't have a lot of faith in things such as that. I test drove it and everything seemed fine I just hope the chain stays together. I want to thank everyone for their experienced support through this job! 👍

When I did a lot of remote roaming about on two wheels I used to fit a spare master link over a brake or clutch cable at the bars.

I have always used the old race to install the new one.

👍 Agreed but dont go too deeep with it or you will have to get it back out.
