I agree!
Really nice job with the videos, tutorials and all the information you gave us!
Thanks Burn!

There is something I don't understand. How could the shaft come into contact with water and rust so bad? Isn't it supposed to be sealed? If not, is it possible to seal it?

rogerl · 08-20-2009, 01:58 PM

How far up the drive shaft is the rust? Could you post a picture of the entire drive shaft? There is a seal at the wheel end of the drive shaft that should keep the water out. Somehow it looks like there was a lot of water in the housing around the drive shaft and it just sat by the wheel until it rusted the drive shaft enough at the seal to let the water in. It looks like one of the photos shows rings where the seal had worn into the shaft.

Wow guys Thanks I'm overwhelmed with appreciation!
Here is a couple videos I just did.
1 to show the shaft and the oil seal..helps to put things in place for ya.

http://www.youtube.com/watch?v=Zld5P4xoQ8E

1 to show what has to be done to grease the U Joint and front drive shaft splines.

I don't think I left anything out ..I may have though I don't remember ...my mind is foggy..or smokey ,or maybe that was my room? lol

I realize most of you still have the fake swing arm on,so yours may appear different.There are 5 (i think) additional bolts to remove for the fake swing arm.
Thanks again everyone!

There is nothing on the parts diagram labeled "boot" at the final drive end. There is, however a "boot" on the engine end of the propeller shaft. My source - M50 Manual. If your shop manager is calling the oil seal a boot, somebody is confused. Items #18 and 23 are oil seals at each end of the final drive coupling - the part that you broke. Item #9 on the other attached sheet is the "boot".

Happy to be able to add something to this thread. I installed the DJ drive in my bike a few months ago so I'm familiar with how things are put together on the final drive. I was also very interested to read about your failure. If I remember the DJ drive installation instructions correctly, they advised to put some RTV sealant between the final drive housing and the propeller shaft housing flanges. There is no gasket here and is a possible source for water intrusion. Hope you get it all back together soon and can enjoy the 50 again.

rogerl · 08-20-2009, 09:09 PM

Burn:
How did the water get between the two oil seals? I would have expected to see more rust on the drive shaft than there is. I could see if the splines had no grease they would wear out from lack of lube but you have some serious rust on the splines. Again, how did the water get between the two seals. Was there water in your final drive oil?

Roger L

burnchassis · 08-20-2009, 10:14 PM

No water at all in my rear drive oil.
No idea how water gets in...I can see water possibly getting behind the front ujoint boot,and leaking to the back,but I see no way water can get in the rear.

does the swingarm really have to be removed to grease the u-joint? It can't be accessed at all with the swing arm there?

Yes ,thats the only way you can get to it.
Removing the swing arm I would rate a 3.5 outa of 5 wrenches difficulty.

gr8stdane · 08-21-2009, 10:19 AM

So it sounds like our options are fix it ourselves, or take it to the dealer. What is the dealer gonna say when every single one of us drop our M's off to have the drive shaft lubed? And if they do lube it, the only way to know if they did anything is to tear it all apart again.

I still haven't seen anyone confirm that this is applicable to any years other than 2005 models? I know I've seen some 2005's with 40,000 miles already, and they're still running strong, and likely they didn't think to lube the drive shaft. And I'll bet DragonRider probably has over 50,000 miles by now. Maybe if you ride in a lot of rain it's a different story.

Does the u-joint have a zerk fitting?

**Trapper** · 08-21-2009, 11:07 AM

Good thing we didn't ban you. You're a freakin' hero!

**Trapper** · 08-21-2009, 11:08 AM

burnchassis · 08-21-2009, 11:22 AM

I seen no grease fitting on the u-joint itself.I also never seen mention of any fitting in the manual.

I too am very glad you didn't ban me

Thank you sir!
Any chance I can get a section under links ,and tutorials,so I can post some more stuff?
I would like to post my signature under a section called
"BURNCHASSIS HOW TO's"
I plan to make more videos when i do the final drive,and then I would like to post a HOW TO CHECK YOUR CAM CHAINS video next.
My signature is full,and It can be cleaned up nicely .
Thanks again everyone!

Wow, a Cam chain video would be great! Lots of work I imagine, but still great too see. Give him a section for his how-to's!

PerfectStranger · 08-21-2009, 01:00 PM

Possible to add a grease zerk after lubing and before putting it all back together? Or will packing it with the Moly make it good for life?
