750L3 starter clutch

Okay,
Most everything came of easy, except the clutch hub. This isn't a left handed nut is it? I can't budge it with a 2' breaker bar, so I'm thinking of going to the impact driver. Safe to do?

Not left handed thread. You can use an impact wrench to remove it, but make sure to use a torque wrench to install, and make sure the washer goes on the right way, I just did the starter clutch on my 650which is identical if yours is a four cylinder.

Just done the same to my L3, and it's not left-handed.
My impact driver could not do the job. I had to use a 2m long pipe to get enough torque on the nut.

i need to do the same thing someday on my 750R1 but i cant do it at my apt complex. i dont have the confidence in myself to do it. it seams difficult to me.

Thanks everyone

With a little help from a Dewalt 18 Volt impact,I was able to get the nut off. For the record, the impact diver didn't loosen the nut much, but enough that I could turn it with a 2' breaker bar.

After dropping the oil pump and removing the retainer clip on the gear on the secondary shaft I was able to "tap" the secondary shaft into the right side case. I still haven't taken it out yet, ran out of time. Is there any trick to this?

Kzipper, Do you need a press to put the assembly back together after taking it apart? Just wondering whats ahead of me. I've owned this bike since new in 83. I hate when it is down, even though my newer bikes are much more capable and easy to ride!

No press required, it will tap back in, just hold the starter clutch assembly from underneath and slide the shaft all the way out to the right, then you can pull the large gear out of the clutch, then disengage the starter clutch from the primary chain and it's out.


Here is a link the the pdf I used when I did mine (Thanks to onkelb at kz650.info)

Hope that helps.

Update?

Did you complete the job?

Zipper,
Now yet, just got the replacement bearing, the one under the starter clutch. The needles fell out while I was taking it apart. I'll probably get to it tomorrow

Almost there

All the guts are in, Oil pan and clutch are back. Just the shifter cover, shifter and exhaust to go. Should be done tonight

Okay, She is done!

Starts like a champ, road it for about 1/2 mile, with no issues. One drop of oil off the pan after approx 4 hours, I figure maybe that was already there during assembly. I'll track it for a couple days.

Here's a short video of me starting it 3 times. It is nice to have a starter clutch that works and even better sound like it was new. Probably save the battery too

Note that I said "new starter" when I meant "new starter clutch"

Sweet!! Nice job and nice bike! Ed

Did you just rebuild or completely replace?
