Really bad news, need guidance [Driveshaft/clutch/transmission] (82 GS1100GK)

[Steve]

Good news all, we found the (or should I say 'A') problem!

That is a GREAT picture of a dirty part.

Now, please clean it off and try again.

Last I checked, we were trying to diagnose a PART, not the GREASE.

Steve, sorry but I'm using a 4 year old phone to take photos. The grease is caked on and wouldn't come off with dish soap or anything else. But the TOP of the splines are present, the rest are not. Definitely in line with the other threads I have found where they had the same issue.

I will check for play with the shaft before tearing into anything else if that is not a weak point. The only reason I asked if I should continue tearing into everything is because.. well I've already got everything torn out. Better to have to take two more things off than to put it back together and have to take it all out!

Edit: Dropped it into first gear, grabbed the drive-shaft, it moved MAYBE 5 degrees before stopping. Is that acceptable? Also Dawn Of The Planet Of The Apes is an awesome movie. I will continue the search for a replacement gear thingamajig.

Edit2: Think I found it! http://www.bikebandit.com/oem-parts/...21373sch281780 Part number 14: JOINT ASSY RR H. Bike Bandit P/N: 1111734. Just wanted to check before pulling the trigger on $150. Let me know, thank you all so much!

I used the '83 parts fiche just in case to make sure that you get the good splines. Check to see if the '82 part has the same part number just to be certain though.

Get a small bucket and some gasoline. Soak it about half an hr and then get after it with a parts brush or some old tooth brushes. Then final clean with the dish soap.

GSX thanks for the link! It was cheaper than the ones I found, AND I stacked a discount code for another 10%.

Chuck, here is a better photo for you and Steve. I might not know what the part is called but I can definitely tell that it's FUBAR. http://i.imgur.com/49JmVnc.jpg

Thats the spline. whats the other parts look like? Teeth chewed off them too..or should I say just how badly re the teeth chewed up. Some pics of the male gear will be useful as well.

Chuck,

As you guessed, some parts of the male gear are chipped off as well. The driveshaft / driveshaft receiver are both fine upon closer inspection though.

Looks like I will need to replace that gear as well. I looked but it does not seem like removing the 10 bolts will let me slip everything out. On the inside of the female gear for the drive-shaft, I saw a c-clip at the very bottom. Do I have to take that off to break down the whole assembly?

You don't need to replace anything but the driven spline in the wheel.

Leave the final drive alone. It's fine. I've seen far worse damage to these that has caused absolutely no problem whatsoever.

Unless it's replaced before failure, the driven spline (the one in the wheel) fails on every 82-84 shaftie. Every. Last. One. I recall a few cases where loose bits of metal damaged the seal in the final drive, but I don't recall any cases where the splines in the final drive are too damaged to use. I'm not saying it couldn't happen, but I know for a fact that I've seen far worse damage that hasn't caused a problem.

Install a new driven spline. Apply a reasonable amount of 60% moly paste -- your friendly local Honda dealer will sell you a tube that's a lifetime supply for I think about $15.

Ride happy. Find something else to worry about.

Thanks BW. I'll clean it up good and then grease it when I get the part in. I'm really excited to be this close to having it up and running. My buddy just got a GSXR and had me ride it (he isn't quite confident) and damn did it give me the itch to ride! Sooon!
