650seca clanking driveshaft/ won't go

Working on my 82 seca 650 and when I attempt to take off in first gear it starts to got then you hear a big clanking noise,first time it was the shaft was not in the u-joint but rather beside it, I believe I have it in correctly(maybe not since it's still not working correctly) I'm really just guessing that it's in as it's very hard to see in there.... This is ,I hope, the last thing I need to officially be on the road! Any suggestions would be greatly appreciated!
P.s. I'm not a mechanic and this is my first bike so bear with me!

 

There is a small wire clip that holds the front snout of the driveshaft (splines) into the u-joint and prevents it from "wa;ling" out of the u-joint hub splines. If that circlip is missing, what you describe will happen. The small wire clip/ring is hard to see in the limited space down there!

 

There is a ring right below the splines as you said,bent slightly but otherwise still attached securly....I wish I could figure out how to attach pics to show you what I'm seeing.... After looking at it again I'm thinking that I might not have gotten it back in as I had thought...I'm hoping that I do not have to remover the engine to correct any of this....

 

No need to pull the engine, you can simply remove the drive and slide the shaft in. There is also a spring that should be in the end of the shaft (part 37) that "pushes" the shaft forward to ensure it is engaged all the way in the u joint yoke.

The drawing is a little misleading, 32-34 are on the rear of the shaft once installed. 36 is the clip chacal is referring to.

 

Does 36 attach to 31? Because that's where the clip is I was thinking of ,just wanna be sure we are on the right page...(or parts)
I haven't yet torn it apart enough to check the spring but when I pushed on the shaft it did move in a bit and then back out on its own..... I'll be back out working on my bike around 630-7 and will check things out more then....

 

Yes 36 snaps onto 31, there is a little groove in the splines. When I did mine, I found it was easiest to insert shaft into the swing arm and then install the drive. That allowed me to make sure the shaft was engaged correctly and not wrestle with the whole drive when installing the shaft.

 

Ok yes that's one that I note was bit bent,mostly just the little hole where you would put the snap ring pliers.....once I get home I'll take it all back apart and recheck that and try to do it the way you suggested,ill have to dig around to see if I have snap ring pliers ...I have them some where but my tools are,unfortunately,spread between 3 different locations the furthest being 4 hours away

 

The snap ring should be towards the back, it goes on after the seal and washer. The ring at the front that snaps into the u joint yoke is just a round clip. If you have a snap ring there you will not be able to get that shaft in.

 

So I need to take that snap ring of by the splines to get it in the u-joint hub? How do I get it back on once its in there? There is very little room to work and see ....

 

Here's a pic. There should be a clip in the area circled red. If you have a snap ring there you will have problems. There is a snap ring a little further back, that can stay.

 

The spring clip has to be on the drive shaft before you insert it into the U-joint socket. The clip compresses and then pops back out to lock the two parts together.

The clip looks exactly like a single open-loop of spring wire, because that's what it is.
Simmilar to the piston wrist pin clips seen below.

 

Hmmmm the one further back is on but nothing where you circled, in fact there isn't even a groove for it....I'm trying to upload an image but it's too big....

 

Here is what mine looks like

 

OK some did not have that clip.

How do the splines in the U-joint socket look?

Does the U-joint have any slop to it?

Was the spring between the drive shaft and the final drive there when you disassembled it?

Be sure to clean all tha crud off the splines and re-grease them with a high-pressure moly grease before reassembly.

 

I can't see in to see what the u-joint socket looks like....yes I will clean them! Ill have to pick up some grease today....and I didn't see a spring where is it located? Is there a diagram?

 

Part 37 in the diagram I posted earlier.

 

The diagram is above. The spring is #37.
You'll want to peel back the rubber gator from the driveshaft to get a good look at the u-joint.

 

IT WORKS!!!! splines weren't properly aligned! Thank you everyone for your help! Jayrodoh, I took your advice and took the shaft off and lined that up first without the drive,thanks for the suggestion! Now to get it inspected and get out and ride! ( Definitely need to work on my turns)

 

Look where you want to go. Target fixation is real, focus on where you want to go and it'll work out. If you come in hot, ride it out and don't panic.

 

That's what I'm working on,im turning really wide, definitely need to adjust breaks too ....but hey first bike,first time riding so I guess it to be expected lol

 

Glad we got that straightened out. Now, aren't ya glad I told you to go get your bike back from the shop and do it yourself??? And, for the record... What did the shop want to do--- tear into the transmission, right? And after a bunch of questions over the phone, what did I tell you?? It's either the driveshaft, u-joint, or rear end.

Over the phone!!! And the "mechanics right there in the shop" couldn't figure that one?!? Just reinforces my reservations about shops......

Lol

As am I!

 

Smeagol, Please don't let your enthusiasm to ride put you at risk.
What condition is your braking system in (last time front and rear rebuilt?).
Have you taken any motorcycle riding courses? Read any books?
Two wheels is really serious - and if you don't respect it you can get a real serious hurt put on you.

If frightens me to hear your comment about wide turns.
A motorcycle safety class will teach you proper turning technique, this https://www.amazon.com/Proficient-Motorcycling-Ultimate-Guide-Riding/dp/1889540536 will explain why you turn the way they tell you.

 

Its just like riding a bicycle. If you are going too wide in a turn on the bicycle, you'll stop pedaling and apply brakes, right? Same theory applies. If you are on the gas, you will be pushed wide. Shut the throttle and reduce speed, your turn radius will decrease.

 

Breaking system is all completely rebuilt new new line,pads,fluid,calipers rebuilt,the works! That was just a couple months ago that that was all done.....
I haven't taken any courses yet but I am looking in my area,the biggest issues there is being a full-time single dad of two kids so my free time is limited to an hour or two on Sundays while my kids are in church....
I've ridden dirt bikes before so I get the basics of it but it's a different style of riding....
I probably should have mentioned that I'm making wide turns is actually when I'm going much slower, so far just to test it and make sure everything worked again I only took up the road a 1/4 mile at best( enough to hit second gear)
And yeah I've been reading a lot online and watching a lot of videos but like wilderness survival it's one thing to read something and do it in theory than it is to do it in practice,but our church has a HUGE parking lot I can practice in which is what I'll be doing when I ride for now....

 

But there's more to it than that. The bicycle theory is correct, but it's simplistic for motorcycle theory.

That's exactly how I started out, learned a LOT as I went a long. Figured some out by myself, and asked/listened/watched. Had I taken the course, I probably would have learned all that in a day......

 

Hmmmm I'm trying to remember the last time I rode a bicycle,i think I was 14lol

 

As I said the hardest part of taking a course for me is time and a babysitter....but it's something I fully intend to do.... I probably won't even get to ride it again until Saturday or sunday....

 

Seat time is the best teacher. If you live in a rural area, just get out there and ride. Take your time and be deliberate. Someone mentioned "target fixation"- it is a real thing. Stare at something you don't want to hit, and you WILL hit it. Likewise, stare at where you want to go, and that's where you'll go. The human brain is an amazing thing... If where you live is congested, then get the bike out to the country via a truck or trailer, and do some nice easy rides. Eliminate the traffic variable until you are comfy.

Also, you mentioned dirt bikes- I have taught around a dozen people how to ride who had never ever been on a bike before, and I always insist they start in the dirt fist. I have been riding off road and motocross since I was 5, and the skills you learn on a dirtbike absolutely transfer over to the street in a big way. If you have access to a dirtbike, start riding every chance you get. Ride in the woods if you can- force yourself to get comfortable making turns and maneuvers with very specific rules (avoid that tree, this rock, etc) where accuracy is key. Then when you get on the streetbike, you'll be amazed how easy it is to avoid that pothole or this crack, etc.

 

I'm right on the outskirts of town so one direction is city,the other is country.... I still have to get the actual inspection done on the bike yet so that will be a nice little ride for me....just gotta find the time to do it.... This bike honestly is going to be more of my Sunday rider lol

 

Don't you have motorcycle driving licenses in the US? The reason i ask is here we got it with the car licenses back in the old days think it was changed in the mid 70's.

 

Yeah I have the learners permit but legally if it's for personal use you do not need any drivers license, for those that do not believe me look up "freedom to travel law" and "freedom to travel without a license" it's a constitutional right/freedom!

 

Proficient Motorcycling by David L. Hough. Get it, read it, practice it.

 

I think you would be in for a long, expensive battle if you get pulled over and actually try to use that argument----

 

But you don't get it with the car license either? (I mean you have to get them separately?)

 

Maybe ...but if you can provide laws and proof thereof not much they can legally do to you,its a constitutional right same as freedom of speech,2nd amendment....and so on....haha id still try it.....

 

Yeah you have to get them separately....they do different testing for each....

 

Well......I guess I'd rather feel a bit more at ease thinking that pretty much everyone around me has gone through a licensing process and theoretically knows what they are doing, rather than thinking that so many people around me have no license because they know all the other laws inside out.........

 

Case law is clear on this matter. Operating motor vehicles on public roads is a privilege.
The right to travel does not equate to the right to operate a motor vehicle without a license. You will lose.

 

http://www.lawfulpath.com/ref/DLbrief.shtml,once you stop exercising or fighting for your rights you are sure to lose them....

 

I understand what you're saying, at the same time a right is a right....and having a license doesn't guarantee they know what they aredoing ,they simply passed the test.....I personally see it as more of an illusion of knowledge/security....it's a feel good tactic much the TSA or printed security bands on medicine,s signing for credit card purchases and the like....credit card information is actually publicly available if you know where it look....in that sense I see licenses much the same way.... But that's just me though lol

 

So then you'd better make darn sure that you never drive any sort of motorized vehicle to get to work. Otherwise, you're trying to play both sides of the coin

That's all I'm saying, cuz it's not a debate that I'm going to worry about.

 

My Mother has a motorcycle licens, she's never ever been on a motorcycle.....so it's definatly not a guarantee....

 

SIgh........

You do know that that site (and all sites that profess to think the state has no right to license drivers) quotes snippets of case law out of context, and never mentions the actual findings of the court, and never cites a final ruling by an appellate court. Nobody has a consitutional right to operate a motor vehicle on public roads. The government can lawfully and constitutionally impose restrictions where there is a compelling state interest. Public safety is a compelling state interest. Licensing drivers to ensure a minimum standard of ability and knowledge is a compelling state interest. There are literally dozens of federal appellate court rulings on the matter.

 

You're exactly right! That where licensing laws are actually valid it's kind of a catch 22.... So legally I could ride my bike for personal use but if I'd use it for work they could nail me....and there are plenty of won cases with this....but just to be clear I have my driver's license and will be getting my motorcycle license...just stating that it is actually legal to operate without one....

 

It is absolutely legal to operate a motorcycle without a license... on private property, but, as others have said here, it's not going to fly on a public street. If you could somehow figure a way to stay on private property (with the permission of the property owners, of course) you could go pretty much anywhere in the US without a licence, car or otherwise. Hmmm, that would be an interesting stunt to pull: see how far you could get that way.

Anyway, I would definitely recommend taking the MSF course, if you can. It is free in our state, and you get your license at the end of it, assuming you pass. I have heard that it is a little easier than the PENNDOT one, and I would take any alternative to sitting around at the DMV anyway. Plus, you could get a break on your insurance too. My wife passed the test with literally no prior motorcycle riding experience. From the time she passed her permit to being fully licensed was two weeks, ha ha. She could have hopped right on a 'busa if she felt so inclined (and had married someone with greater financial means). There were several locations around me that you could take the course, and a lot of Harley dealerships offer them as well.

Note that at the bottom of the page it says that some of the items might be paraphrased. A cursory examination of the actual cases finds that the editor(s) of this piece equate a parade permit with "license" , which is close enough if they weren't implying that it applied to a driver's license. I just looked at a random few of those cited, and they were all similarly misrepresented. I'm all for trying to keep the government honest, and knowing your rights, but you need to vet your sources. There are plenty of instances where the government hides, or actively discourages its citizens from exercising their rights (jury nullification, anyone?), it just doesn't seem like this is one of them.

 

I FIRMLY believe that people are interpreting it wrong.

Just like the "right to free speech" issue. Sure we have the right, but there are inherent and/or consequences depending on just how/when where one decides to excercise that right.

The right to do something does mean you don't have to follow certain rules or certain aspects.

 

I agree- the "right to travel" surely applies to any means of non-motorized travel. But when you add a motor vehicle into the mix, you must be licensed to operate on public roadways/land/etc. You can ride your horse, bicycle or dogsled anywhere you want free of charge though. Heck, you might even be able to get away with anything under 50cc's too- like a go-ped.
