Rear wheel gets stuck if put in first gear

Yes I did. Mea culpa. I got a full clutch assembly for $40 in eBay from a seller that I have bought before. He assures me that everything is in good usable condition. He also told me the same thing. To get new bolts.

 

I agree with replacing the bolts. But how this pressure plate got so damaged? Maybe the bolts got loose? It just snapped.

 

your lucky a few years ago we had 2 or 3 members have the clutch let go with catastropic results

 

The bolts eiter got loose, or broke. It dosen't take much for the pressur plate to be damaged once the assembly comes apart while in motion.

 

Did you have the tabs on the clutch centre nut locking washer folded over the nut to stop it slackening?

 

Ouch, glad you are okay and the bike will recover.

 

Yes, and I adjusted the nut to 52.7 lbs which is the specific torque according to the manual. I also bent the washer accordingly. I already took everything apart and had to remove the oil pan to clean the debris that was there. Now Im deciding whether to buy a new pressure plate or use the one that is included with the bucket that I bought on Ebay, which comes with a pressure plate and all the clutch plates as well. I just don't want to keep throwing money at this thing.

 

Thank you man.

 

Good you are ok and caught it in time.

 

what torque did you apply to the clutch spring bolts? 7.2ftlbs?

 

Ow, that's a bummer.

 

Yes. That's what the manual says.

 

The third picture showing the large nut that secures the clutch basket it looks like the nut / basket is not fully seated; the nut should be flush with the end of the shaft. Perhaps you already started disassembly or it's just the photo?

Was loctite used on the pressure plate screws?

And what about the torque wrench? You typically need an inch pound wrench for numbers that low to get into the usable range of the wrench.

 

Has anyone used thread locker on clutch bolts? Just interested to hear your opinions on this.

 

I didn’t use loctite but will definitely use on the new ones that are comings. My torque wrench goes down to 5 lbs so I think its ok. Now, regarding the nut not being flush with the end of the shaft.... I didn’t notice that. I adjusted it to 52.7 lbs which is the specification. I will check that when I install the new one. Thank u for the observation.

 

It's not OK. You want the target torque value to be somewhere in the midrange of the torque wrench's scale, or you won't get an accurate adjustment. This is more critical when the value is at the low end of the tool's range.

i do know what happened to mine. put the bolts in finger tight, went for lunch, had a few beers, put the cover on and a few miles later.......

 

Did something else got damaged? I had to take out the oil pan to clean it from all the debris in there.

 

If someone knows, what it the reccomended measure of the 5 springs that holds the plate? I’ve look at the Haynes manual but I can’t find it.

 

XJ650G
clutch spring free length 40.1 mm
minimum length 39.1 mm

XJ650LJ
clutch spring free length 42.8 mm
minimum length 41.8 mm

I just put Barnett's in my Turbo - 44.5 mm

XJ900RK
clutch spring free length 44.0 mm
minimum length 43.0 mm
I seem to have misplaced my XJ650RJC manual but I suspect same as 650G

 

650 seca specs

 

Thanks a lot to both of you! By tomorrow I should have receive all the parts as well as a new low torque wrench for those bolts on the springs. Hopefully by Saturday in the afternoon she’ll be running again. I really like this bike and don’t want to part ways with her. I want to get her running good.

 

Damn, that's wretched luck..
.. while your in there though how about a new clutch cover gasket? That orange gloopy
sealant is no friend to oil-ways in any motor.

 

Lol. I already got the new gasket for all the side covers. Put the gasket maker on a hurry to get her running. She is running good now but I’m in the process of fine tuning the carbs. The rpm got very high when she gets warm. I adjusted the float levels and performed a bench synch and it change dramatically but still sometimes a bit high around 1,500-1600. New boots are in the way as well as an ultrasonic cleaning and completely new rebuilding kit. This next Saturday will be a busy one.
