New bearing not smooth

[yjanray]

I purchased a new ball bearing for the reverse gear on my MC1 drive. The new bearing feels rough and kind of notch. The place I got it from said it was original stock. How much grease should I pack into the bearing before I mount to reverse gear and then into bearing carrier.

The old bearing feels very smooth. Not sure why the manual says to put in a new bearing if you remove the old one.

None, it runs in gear oil

So once its got plenty of gear oil in it, will it not feel as rough and jumpy?

a new bearing will not feel rough and jumpy right out of the box. smooth as silk or its junk

 

[yjanray]

Booo......got a bad bearing then. That's a huge bummer.

Thanks

Why can't you reuse the old bearing after it has been removed from the reverse gear?

 

[Bt Doctur]

IF the bearing was properly removed and IF it has not been damaged and IF it feels smooth as silk and IF you can re-install it correctly without damage than is ok to reuse.

Ok thanks. I removed it with a bearing separator plate and it came off pretty easy.

Reinstall is going to be a challenge since I don't have a press. Can I hammer it on with a proper sized seal installer?

A large C clamp and some gas pipe will work but press on the inner race not the outer

Did you try to clean the new bearing? sometimes even a little dust can make them feel rough.

So i put some gear lube in the bearing and spun it for a few minutes and it feels much smoother.
It does not spin very long after you let go, but it feels very smooth. The old bearing would spin for a few seconds after you let go.

Does that seem normal?

A new bearing should be smooth. Is the housing for the bearing damaged? Cracked? Is the outer race spinning in the housing?

 

[yjanray]

brand new bearing carrier and brand new bearing. I have not pressed the gear into the bearing yet, so I am just trying to spit it by hand. It feels smooth now, it's just not very free.
No cracks and the outer race looks good

 

[Jcris]

This is a sealed bearing? If so, my experience is they tend to not spin "free" and there is some , albeit small, amount of resistance. The action should be smooth but will not spin freely. It's not like a open bearing that will spin much more freely.

 

[Grub54891]

A new bearing with a bit of lube will feel tighter, as it's not wore like the old bearing. If I have a doubt about a bearing, I clean it with brake cleaner, then feel it for rough spots, if none, lube and install.

 

[yjanray]

Thank all you guys for the assistance. Just needed a bit of advice about bearings. I think i will clean it and check it. I have a feeling that it has just been sitting around for a while and had some dust or other grime in it. I think it will be ok

Thanks again! Much appreciated

If you put even the slightest pressure on the OUTER of the old bearing as you pressed it off, trash-can it.... Putting pressure on a bearing like that, that isn't spinning, puts microcracks in the balls and races hardened surfaces, meaning a much shorter life-span....

When you press the new one one, only press on the inner race...

Thanks for that information. I contacted the place I ordered the bearing from and told them it was rough when I opened it up. They finally got back to me today and are sending me a new one. It was an original stock bearing, so not sure what that means....

Anyway, I am getting a new bearing and now I just have to figure out the best way to push it on the gear and then into the housing. I don't have a press, so might have to take it to a shop to get that done.

 

[Jcris]

If you don't have a suitable press, consider having it done at an auto parts store or even a shop.

2 options from a 'cheap man's press'.

1. If the press load isn't too high, a good vice will suffice.
2. (And I suggest this one with the upmost caution). A motor car can exert a fair pressing load. Raise the car on a controllable hydraulic jack, set up what you need to press, the lower the car onto it very carefully. Done properly it is effective. Done badly, you could damage the part, your car, or yourself.

Although, the best option is to buy/build a press. You'll find uses for it you never knew you could. A brilliant tool to have.
