Lipstick works really well...just don't let your wife catch you using hers!
HUH? .... you have some of your own ? :lol: :lol: :lol:

Shhhhhhhhhhhhh! Don't tell anyone! :P
This isn't as big a deal as you might think.
Women frequently buy lipstick and then decide they don't like the color, consistency, staying power, whatever.
So just ask your woman to set aside any lipstick that she doesn't use, instead of throwing it away.

It has a myriad of uses. Use it on the corners of electrical boxes, then press the sheet rock against it to get the exact positioning.
When checking the clearances of tight parts, spread it on things and assemble, then take apart and see where it has transferred.
Wonder how hot a mechanical part gets during use, but can't reach it when it's in use? Put some lipstick on a metal plate.
Heat gently with a lighter, observe where it goes liquid and measure temp with a IR thermometer.
Now apply lipstick to the part. If it melts you know you've exceeded that temp at some point.

Just make sure you smear some nasty black grease on it, so your buddies won't think you are using it to dress up as a lady. :-D

It's not the brand, so much as color coordinating with your rigs color...

Is there such a thing as useful nattering? :?

While I wanted to document my final drive rebuild and share what I found for both my own edification and the enlightenment of others, I never intended this to be a step-by-step illustrated diagram of an FD rebuild.

If someone wants to make it pretty, put my pics in order and make it into a guide, be my guest, just credit my pics.

Otherwise I will be interjecting nattering, both useful and otherwise, throughout.

On topic, I picked up a replacement for the pinion bearing, fig 3304B.TVH.
Billy G. refers to this as a "#5304". The dimensions for both a 3304 and 5304 are the same, but the one I sourced has a steel cage and higher load ratings than a 5304 and the fig 3304. The fig was not available locally.

This was necessitated by the discovery this weekend of some tangible drag and a slight "grittiness" in the bearing after cleaning it. I think some metal shavings/pieces got in the bearing. I cleaned it with solvent and reoiled, but couldn't get rid of whatever was causing the issue.
This is probably the most crucial bearing in the FD, so I didn't want to risk it and got a new one.

Good on you...one of my FD fiasco was this. +1 on the higher load rating, this bearing takes/absorbs a lot of loading, IMHO. The bearing fell apart & the FD locked up, made a terrible sound. I had just exited I-40 & into a truck stop when it locked up. :? Oh well...

OK, I may have found an error on the Ural Parts list...

I went out to the garage tonight to work on the FD in preparation for finishing up tomorrow with a little help from ReCycled.
I pick up the new bearing and WTF? "Houston we have a problem..."

The bearing I need to replace is this one in the spline hub, where the 2WD yoke bolts up...

Image

If you note at the top it says "3204B.TVH" It's hard to see, but cleaned up it is very clear.
Well when I ordered the parts I was looking at the Ural Parts diagram and list...

Which is in the lower right of this diagram, labeled #45...

Image

Which the parts list calls 3304B.TVH...

Image

So since I was looking at the parts list and not the actual bearing when I ordered, I received the wrong part!
The 3304B bearing is the one on the pinion, so when someone was doing the parts list they stuck that bearing on twice and the 3204B bearing, not at all.
For those of you looking at the Billy G page this is the "204" bearing he refers to, as it's equivalent to the SKF 5204.

So I am dead in the water on my rebuild. Fuuuuuuuuuuuuuuuuuh....

It's only 6 days to the Jersey Devil Hunt...I should have known it wouldn't be THAT easy.
I'll be scrambling tomorrow trying to find a bearing shop that's open on a Saturday.
If not, I'll have to source it locally and send the 3304 back.

There isn't a local bearing supplier with that bearing in stock?

I called all over, NAPA was the best bet; they had it in the warehouse, said they could get it 1st thing Monday. :(
All the bearing suppliers near here were closed on Saturday. I guess they do mostly commercial sales and not much walk-in business. :(
None of the local Ural dealers had it in stock, they all had the 3304 in stock. :o

Phila. Ball and Roller will have it, I'm going to swing by there 1st thing Monday morning.
So once again I'll be wrenching on the bike right before another Jersey Devil Hunt. :evil:
I need to do the alignment as well, but of course I can't do that without the bike together. :roll:
