service differential - now no gears

[naturbar]

i have an 07 rstd - had to replc. rear tire so i did all the normal rear wheel maint. - swapped inner/outer rear pads - pulled hub off and greased pins - greased outer diff. gears and matching wheel diff. gears - pull diff. out (from bike only - not from rear itself) greased the splines - drain diff. and replaced gear oil. reassembled all parts - put it on the ground, cranked it and tried putting into 1st - it wouldn't go, actually won't go into any gear. also when you roll the bike it creaks (diff.?). the only part of this job that caused a little trouble was putting the drive shaft back into the bike, once i got it line up i had to give the back of diff. a good smack with the palm of my hand to get it seated - the four flange acorn nuts were hand tightened (these were the last nuts to be tightened in reassembly) and everything seemed normal. hopefully i did not screw something up too badly...any ideas/suggestions or anyone else ever run into this problem??........HELP !!

I have a feeling that you didn't get the driveshaft seated, even though you said that you did. That job is a real mutha. I couldn't get mine in at Kbays MD, and finally had to let Squidly do it.

[SilvrT]

The "creaking" when you try and roll it may be due to improper reassembly of the washer and the caliper bracket ..???

 

Other than that, I dunno why it wouldn't go into gear... do you mean the tranny won't go into gear or you can put it in gear but it won't move? Seems odd that doing that work would affect the tranny shifting?

Do you mean the engine end not going into the yoke? So, the yoke is hanging there and the driveshaft is stuck over to the side of it?

 

I suppose that could be possible?

when i smacked the end of the diff. and it went in and both flanges met up i assumed the shaft had seated properly. i guess i don't understand how it could seemingly all go back together and the shaft not be engaged?? is it possible that the shaft moved (opposite direction) further into the diff.?? i don't mind taking it all apart again - i only hope i didn't mess something up :-(

 

" do you mean the tranny won't go into gear or you can put it in gear but it won't move? "

 

when i said it won't go into any gear i meant you cannot get the trans to shift into a gear (any gear)

Yes, this is possible and a dollar to a donut, is the problem here. BTDT just last month.

 

The drive shaft will fit next to the U-joint yoke and jamb the works when you try to put it into gear. Take it all apart and try to re-seat the drive shaft.

Once you have it all back together, have the transmission in neutral, pull back the boot covering the front of the U-joint, turn the tire, and make sure the U-joint turns.

 

Be patient and the shaft will go into the joint. If you don't know, there is a plastic plug on the side of the drive shaft housing that will allow you to use a piece of wire (coat hanger, car antenna, heavy gauge copper wire, etc.) to line up the yoke.

 

Good luck.

Before you take it apart, you can confirm this is your problem by checking the front of the yoke (pull back boot, rotate tire, etc.). If the yoke turns with the tire, I owe you a donut (or would I owe you a dollar??).

i found this site for the service manual but every time i tried to download it , it just goes to 3.14 mb and freezes. i just wanted to 'see' the shaft nomenclature to get a better understanding...does anyone have another site where i can get the serv. manual?

 

here is site which locks up..http://labs.trunkful.com/vrmanuals/index.cfm

 

and thanks guys for the inputs - tomorrow i will look to see it u-joint is turning.

[buddy]

I had this problem on 83 Venture. I mis lined my drive line thinking it was in and it went beside the U-joint and I found I had no gears or shifting it was in a bind

I never made that mistake again:whistling:

[Freebird]

I made that mistake also. The shaft will slide all the way in right BESIDE the U-joint instead of in it. Dropped mine into gear and it made an awful noise. I knew immediately what I had done and was very careful after that.

Below is the swing arm section from the RSV service manual that may help you see what you are dealing with.

Your drive shaft is not in the U joint, and you should never ever have to smack the differential to put it into the U joint.

[naturbar]

Gary thank you very much for the pdf - it helped greatly. i got a call from Ruffy a little while ago and he explained that there was a u-joint that the drive shaft couples to (i did not know this). when i read the instruction on reassembling the drive shaft i apparently misunderstood what was said. i thought the you were supposed to use a piece of wire, antenna or something else to hold up the drive shaft as it was sliding in - when in actuality you are supposed to support the u-joint in order for the shaft to fit in. once Ruffy told me about the u-joint the proverbial light bulb turned on. i now realize i must undo everything and do it right. Gary also asked me if i had removed the axle from the pumpkin and i told him i had not, he said it would be difficult in his opinion to try to hold up pumpkin w/ axle attached and hold up the u-joint and align them both - he suggested for me to remove the shaft completely (watching for the spring). has anyone done the reinstall w/ the pumpkin attached and if so was it really hard to make it work that way. thanks to all you guys and where else can a fella get this kind of support for $12 a year. anyone out there that is a trial member, pay the $12 and belong to the greatest yamaha site. you guys rock...

 

ps - a shout out to Condor for sending me info on the service manual.

[RedRider]

Yeah, it's not too hard to do the drive shaft with it still installed in the pumpkin. I've had it out of the U-joint several times but have never removed it from the pumpkin. Just be patient, use a flashlight to look up the shaft tube to see that the U-joint is centered, and slide it in. Easy as that (OK, it's not really that easy, you will need to take a few swings at it).

But be sure to leave it in gear, otherwise if doing it this way, the U joint will move around in a circle beside doing the flop act. But I do it this way all the time and usually have it in under 10 min (with the pumpkin attached).

Ditto that and where else can a guy learn so much from other's experiences. Without such a forum and the great folks here.... many of us would be lost and forkin out big bucks to some shop.

 

This issue of the shaft going beside the yoke has never happened to me but thinking about it... sounded like a possibility... and sure enuf... it can happen. A guy learns something every day here!

 

[The Marshal]

I was soooo proud of myself.

Got the tire changed, everything lubed and greased, and all re-assembled.

Polished it all up, and then backed it out of the garage to go for a test ride.

-Nuthin.

No gears at all.

 

I jacked it all back up, threw all the parts all around the garage, and after fighting with it for an hour... called Squidly

What a great guy! He listened to my story, laughed at me, and then said something like "Good luck."

 

Actually, his best advice was to "walk away from it for awhile, and get a fresh perspective."

I did! And the next morning, I had it in place in under 30 minutes.

Ahhh. Experience. It is best learned the hard way. But it is not so bad with friends, heheh.

gentlemen,

my son & i took it all apart again this morning and followed Ruffy's instructions (spot on) - it definitely is a two man job to get that u-joint lined up with the drive shaft. was real happy to pull boot back and see the u-joint turn but i still could not get it into gear -mmmmmm? put the rear tire on to the pumpkin and spun it several time and viola it would now go into gear , yeeeeeh ! took it for a test ride and it is smooth. once again to all who posted, i thank you !
