|
|
Hi everyone,
I keep having my rear outer wheel bearings fail after a few hundred to few thousand kilometres.
I assume I have not packed the outer needle bearing properly? I have looked through discussion of this but no one seems to have good instruction on how to do so. The grease in the palm of hand method will not work because of the design of the needle bearing with the only exposed bearing being in the middle where the inner race sits. the ends are completely close off. Thus bearing is different than a typical needle bearing.
Has anyone done this successfully?
Thanks! _________________ 84 Westy

Use a wheel bearing packer. _________________ T.K. |

I like my Snappy 18v grease gun, 30" hose whip and grease needle.
Very civilized and the grease goes where you want it.
The greaser pulling the trigger determines the mess factor.
Pictures of the setup can be found in the Luxury Tool thread. |

Another vote for the 18v grease gun. Love my Milwaukee! Throw a needle fitting on the tip and you can squirt till your hearts content wherever you see fit. Small rag to clean up excess and your good to go. |

Ahh yes, a core human need. Perhaps not wherever you see fit though.
Are you saying that with a needle extension you can get fresh grease into the bearings without disassembly? Can you get the inner bearing too? _________________

Maybe, Maybe not with a grease gun & a needle.
But I do know that this zerk most certainly will get grease to both bearings pretty easy.

I like that method. A guy could grease that every 100,000 and you'dbe golden. Greasing the bearings every 30 or 50 or even 100 without disassembly is very interesting though.
Mine have 175,000, never greased. It would content my heart to squirt without disassembling (much). A worthy goal I think. _________________

Yup.
I zerk when I replace the bearings, but most of my vans still have the originals going strong as I maintain them with a needle.
New are a crap shoot. |

Another possibility it worn out bearing housings, no? I've seen quite a few cores where the bearing will drop/fall into the housing, as opposed to needing some force. _________________ 1986 Weekender "Birch" |

That,s modern technology.
Back in the "Day" there were no gloves. What ever was touched was touched with skin unless it was hot or caustic.
All of us old farts will surely perish from various cancers leached into our body through the skin.
You younguns........ bicycle helmets, elbow pads, gloves, goggles, condoms, protective this, protective that.......
I guess we loved all of you kids too much and desired to protect you!

I grease the outer bearing using a needle every time I do rear brake work. Remove the seal, squirt some grease into each space in the bearing, wipe off any old grease that has been forced out and then install a new seal. |

I picked up my new bearing today and found there is a design difference between the new bearing and the previous one that failed. They are both needle bearings, however; the failed bearing has no way that I can see of actually packing it due to the housing covering all the way around the outer, top, and bottom of the bearing. This left only the inside rollers exposed for greasing.
The new bearing has the ability to be packed from top or bottom. I assume the two previous failed bearings were because of a design flaw.
I will try to post a photo for comparison. Is there a way to upload photos onto this forum? or can you only post from URLs? _________________ 84 Westy

Sounds like your were sold bearing with either seals or shields on one side, instead of being open on both sides.
To learn to post photos: Look at the top of any The Samba page and hover your mouse over the word "Gallery" which will open a drop down box, click the "Help/FAQs" button and you will find the info you desire |
