GS850 Driven Hub Wear

  • Thread starter Thread starter bbjumper

Question, once the worn parts are replaced, if maintained properly, is this a reoccurring problem with the G model? I hadn't heard about spline wear problems until I started reading this forum, which is why I checked mine. How often should these be cleaned and lubed once new parts are installed?

Thanks
Each and every time the rear wheel is removed to replace the tire is a real good schedule. My '80 850 still has the original splines on the wheel and is pushing 97k miles (a couple more trips like I did today and it'll be there). I got mine with 25k on the clock 6 years ago.

Nice to know, I found an older (79) complete drive unit on Ebay with the hub, a dark one. Any benifit to having a mached set if in good shape or am I just nitpickin?

Matched set is good if the pumpkin side is in bad shape too (which sometimes happens), otherwise, no real benefit. I've swapped wheels all over between my bikes with no real problem areas. Oh, make sure you put blue loctite on the bolt threads when you replace the splines and be sure the lock tabs are hammered tight against the flats. I had one bolt work it's way out once and it could've been a nasty disaster if I hadn't caught it in time.

Once you get rid of the gold splines, you should have no more problems, as long as you lube it properly.
As mentioned, the splines should be lubed every time you pull the rear wheel for a tire change. The proper lube is a Honda product called "Moly 60 Paste". The good news is that Moly 60 really does not wear out or get flung off the spliines, so virtually all of what you put on there the first time will still be there the next time you check. Just spread it back into place, if it got squished out, and apply just a touch more. The splines don't really slide while in use, the lube is more of a cushion between the teeth that are constantly-engaged.

Oh, Moly 60 is found in a small grease gun cartridge and will cost about $12. If you only have one shaft-driven bike, that one cartridge will be a lifetime supply. I have five of those critters running around here, and had to get a second cartridge after about six years of use.

This is what I've got, the only real ware is on the crest of the drive spline, just rounded a bit

That looks perfectly good to me. No need to replace it. Splines are different than bevel gears. Bevel gears should be done in matched sets, splines aren't that picky. If they were, every time you replaced those worn out CV joint axles on your cars you'd have to tear apart the diff as well.:eek:

Thanks Dan,

Got a hub headed my way.

Thanks Steve,

I agree, Honda Moly 60 is the stuff. Thanks for your help
 
If you're looking for a good "silver" type spline on ebay, our shafties use the same spline as many of the post-GS Suzukies, like the Intruder or Madura. I have an '82 GS that came with the crummy "gold" spline, and found a "silver" replacement on ebay by searching Intruder and Madura rear wheels. Found an Intruder rear wheel for $30 including shipping, pulled the spline off that spoked wheel and have been good ever since. I gave away the spoked wheel to someone here on the GS board, so win/win. Also, what they say about Honda Moly 60 is true, really good stuff.

$27.00 on Ebay, from a VS800 Intruder, checked and it's the same part #. Splines are supposed to be perfect and it's on the way. We shall see, thanks for the lead Dpage.

I hope it works out. Actually, it wasn't even my idea, I read about the Intruder / Madura spline source on a post from Bwringer several years ago.
