Topic: 750K8 Clutch problems "Now Solved"

[seaweb11]

I have just removed and reinstalled the friction plates on my 78 cb750K8
Put it all back together and POO! No clutch.  I must have missed something.

Called the Honda dealer mech that works on my bike from time to time, his only comment was that when I try to rotate the lifter plate it should not move. ..... Mine does now. What have I done wrong?

I have a free phone line  1-(800) 352-1137 if someone who knows this sh*t could give me a call.

 I would really like to ride in the next day or so. I'm so close...and yet so far.......

OK, so it looks like I tightened up the screws on the lifter plate a bit to  tight and cracked the preasure plate a smidge
 

That wouldn't have been my earlier problem, but I suppose I need a new one of those now as well

Jump in any time

I cracked my pressure plate too!! and I installed and reinstalled my clutch several times with no grab, make sure you tighten down the pressure plate evenly, and I'd reccomend new springs too. there's a good clutch FAQ on here somewhere, that reccomends that all the
steal plates are arranged the same way, the plates are stamped, so there is a rounded side and a square side, when looking at the edges of the plates.  Make sure that all the steel plates are arranged in the same manner, so that all the rounded edges face the same way in the sandwich. hope that helps a bit

[seaweb11]

Thanks for the input. Will look again tomorow.

Crap

G'Day Derek, your lifter plate has to be perfectly aligned with your clutch hub to ensure that the "splines" on the first  steel plate engages with it, then you have to hold it all together while you evenly tighten the four 6mm screws on the pressure plate.

If you've had it apart, you may have to strip it again to take the lifter plate out, turn it 90 degrees, and start again, making sure all the plates engage. Make sure you replace your cracked pressure plate, or you'll end up with a chunk of it floating around in your transmission! What's the country code for Canada, I wanna try that 1800 number! Cheers, Terry.

Sometimes tapping the pressure plate and basket (not to hard) with a soft mallet will align and seat the plates.

[seaweb11]

OK, so now I need a preassure plate.

Honda does NOT sell them anymore.

Anyone have an extra?

[seaweb11]

Honda no sell no more;-(

OK, I got another pressure plate from another 750 guy I know. Now.......when I put it all back in, how do I know if it is (all the way in)?
Right now I have bike in gear and when I turn the clutch the back wheel wants to turn. Do I have it?

All splines are in their slots including the last one, but.....they don't seem to be tight. I can still wiggle them if I put a screw driver on the outer one.
Also I would have thought that the blot head would be flush with the outside of the shaft. Mine is not, the bolt is still a smidge inside the hole.
 

New thoughts. Just went out to the shop and had another look. If I pull and wiggle the pressure plate towards me I can now feel it slipping into the rear splines. Feels good now. Very solid.  Bolt is still back a bit off the outer edge, but that certainly takes up the slack on the friction plates etc. Now I suppose the trick is to get the springs
and bearing on without that moving. Am I on the right track now?

I would help if I could. I know nothing of clutches except how to use them.

That's it mate, read my post again, you need to ensure that the lifter plate (the one with the four posts) is fully engaged. If it's right, the clutch plates will all be seated with no gaps and no movement. Make sure you tighten the 6mm screws in diagonal sequence, a turn or two at a time, like tightening the wheel nuts on a car. Cheers, Terry.

Works fine inside the shop. Now for a tear around the Island

[Terry in Australia]

Lucky Bastard! Oh well, it's Spring here again, so 9-10 months of comfortable riding weather to come, woohoo! Cheers, Terry.

[seaweb11]

Sorry I took so long getting back....but there are 3 Pubs on the Island

Like another famous Canadian would say (Mike Myers) LIKE BUDA

Man......every time I replace something it feels like a new bike!!!!!!!!
Recent additions....chain, throttle cables, and clutch. WHAT A DIFFERENCE.

I love this thing. 

Thanks for all your help again guys.

P.S. Saw 8 deer tonight but missed them all

P.S. Saw 8 dear tonight but missed them all

I hit a Kangaroo on the way home last night.............. I had to chase the bastard through three fences to get him though, ha ha! Cheers, "Evil" Terry.

Hey Terry, I called the operator tonight.

Wouldn't you know it the Long Distance Country # for Canada is #1
No sh#t

I'm still up,  see if it works from there. I know it works from US and Canada.
Every one should have one, you never need a quarter to call home

[Terry in Australia]

Bloody Department of Defence telephone system, won't let me do it mate, as soon as I tap in the international code it comes up with the disconnect tone!

I've got a "block" on my home phone (oldest son thought it was ok to call all his friends on their cell phones) but if I can remember how to take it off temporarily, I'll give you a call.

Otherwise, my home number from Canada (or anywhere, I guess?) is 011 6 3 9408 5152, just remember the time difference! Cheers, Terry. 

[seaweb11]

It's 10:24 PM here now.

What time you got?

[Terry in Australia]

Friday Afternoon, 3.28 pm, September 9th, 1978! 

[seaweb11]

Dude.....GET OFF the INTERNET and answer YOUR PHONE!

P>S>  you missed a digit in your phone number (61) Country Code

[seaweb11]

Never mind.......I get it, "you have a real job"  Christ I can''t  imagine. How do you find the time to work on the bikes

[Terry in Australia]

Yeah, still at work mate, boo hoo! Finding time to work on the bikes is easy, I just don't do any other work around the house, ha ha! Cheers, Terry.

Check your private email for more on my days adventure

[Terry in Australia]

I will when I get home, in around an hours time. (can't access Yahoo or Ebay boohoo! thru the defence email system) I finish work at 4pm, but it's about an hours drive in my company truck back to the 'burbs" from where I work on a defence base in the middle of the bush. Cheers, Terry.

While you are doing this.....an Elite Force of Canadian Navy  Alberta Frog Men are shadowing the shores of AUS and planting cans of Canadian beer along the beach.

We know that if you are doing this during working hours.........WE CAN TAKE THE BEACH~ and then.........kangaroos, never mind.

[Terry in Australia]

Can you give them my address so they can plant a few around my garage? My beer fridge is in the south eastern corner of my garage, grid reference is: 128173.

Oh and let them know I've already counted what's in there, ha ha! Cheers, Terry. (I'm going home for the weekend, woohoo!)
