Instructions For Techno Clutch Plate Removal And Replacing?

[alanmondial]

Hi all, I'm going to clean up my clutch plates to try to eliminate cold stick on my 1995 Beta Techno. Dan Williams' instructions are fantastic but could someone point me in the direction of a step by step guide / instructions for the process of removing and replacing the clutch plates? I've scoured the internet for any sort of Workshop Manual to no avail.

I want to do the job well and not make a mess of it. Any help would be greatly appreciated.

Hi. First of all drain the gearbox oil or if you are a tight Yorkshireman like myself lay the bike on its right hand side to stop the oil draining out.

Next remove the gear lever then the circular clutch cover. This will expose the clutch unit. Undo the six ( I think ) bolts with springs and washers, with these removed you can remove the pressure plate this will then expose the plates which you can remove by sticking your fingers in the grooves. If you do this with bike upright the only thing to watch out for is the ball bearing falling out from within the mainshaft.

Rgvlc, thanks very much for the advice. That seems fairly straight forward. I'll lie the bike down to stop the mainshaft bearings falling out. Should I be on the look out for wear etc. while I'm in there?

Yeah what he said. Be careful when you pull the pressure plate off not to drop the thrust bearing that'll be stuck to it. It helps as you disassemble to have a nice clean spot to put the parts like a table with paper towels on it. They are greasy parts after all. You can get the clutch pack out by hand but it's a pain. I used to use a small screwdriver with a bent end until I realized the toolbox held some of the bent dentist picks. Those stainless picks are one of those tools you pick up on a whim and just keep finding uses for. I'll just take two and stick them under the clutch pack and it comes right out. Don't worry too much it really is pretty simple. Oh yeah one other thing to be careful of is the o-ring under the cover can be a pain to get situated back in the groove. Be patient and if it remains intractable a few dabs of lithium grease will keep it in place.

I also just lay the bike over.

Also wash the bike first. No point in getting the innards dirty.

...and one more thing, don't over tighten the bolts that hold the springs. they are held in place as much by the spring pressure as bolt torque. If worried put a dab of Loctite on. Too much torque can snap off the studs from the basket. Been there, done that.

Dan, thank you so much for the advice. The bike is pretty grimy so I'll give it a thorough scrub before I start. Are there any particular torque settings for the bolts? The clutch lever is pretty badly damaged. A previous owner also stuck a bolt in it in lieu of the adjusting bolt. It appears that when you pull in the clutch lever it's not allowing the piston in the clutch lever assembly to fully come out. I understand from some of the posts here on the forum that the tolerances on the clutch itself are fairly tight. This may also be contributing to the 'cold stick'. So I'll have to invest in a new lever as well. The brake lever is also pretty shot so I'll replace both of them.

As Dan said no torque needed. Just lightly snug them up, the springs will hold. Too much torque and you will be buying more parts. Ps, Beta`s always had cold stick.

Thanks for that lineaway. I had never experienced cold stick until I got the Beta a couple of weeks ago. I had a lovely Yamaha Ty250 (which was stolen on me recently but that's another story) and never experienced the cold stick problem with that. So I was totally unprepared when I started up my Beta last weekend, pulled in the clutch (or so I thought) put it into first and it threw me off much to the amusement of my three young sons watching. Not something I'm keen to repeat any time soon.

I bought myself a set of precision files and a Dremel last night. I'm going to clean down the bike tomorrow as per Dan's advice, drain down the oil and get stuck in.
