Need advice on Blaster Clutch---What is wrong????

[Blasterbuilder]

Hi guys im new here and i have some problems with my current build.

When i pull my clutch lever, it pulls on the actuator but after that the clutch does not disengage or seperate can you guys point me in the right direction for what to do next? could it be the push rod ball bearing that is missing?

That may be the problem. Make sure the arm on the motor is adjusted to spec. Take the cover off and see if the clutch is moving . You may just have sticking clutch plates from sitting.

when you pulled the pressure plate did the ball fall out. there sould be a ball bearing inside the clutch shaft. there should be a rod that contacts the engine clutch lever then a bb sized ball bearing then the rod on the pressure plate. if that ball bearing fell out it will not work properly

yip, it could be but did you have the motor disassembled?

 

[scotj77]

oh I didn't even notice you said the ball is missing. yes this is your problem. my buddy replaced his with a bb and it works great. or you can order one

Could be missing BB, or the marks (dots) on the pressure plate and inner boss aren't lined up.

yes i had it completely disassembled but didnt split the case or take the clutch apart yet

No i havent found out yet if it is the BB, also it is a problem that the actuator moves up and down in its sleeve

that's ok you can actually just pull that shaft right out from the top. you have to have the ball bearing between the two push rods though

Guys just tore into it and when i pull the clutch lever it pulls 5 of the 7 plates out away from the basket but the other two just stay there as if they are are stuck but i can move them with a screwdriver.

What do you think i should do next

 

[scotj77]

the plates aren't really what needs to move it's the pressure plate that moves the plates just kinda stick to it. did you look at the link slickerthanyou put up for ya

Now when i pull the clutch lever only 5 of the 7 plates move out away from the basket the other two act like they are stuck but i can move them with a screwdriver

What do you think i should do?

 

[scotj77]

that's fine. the plates moving isn't a big deal. the pressure plate is what needs to move and it sounds like you have accomplished that. the clutch grabs by putting pressure on the clutch discs. as long as when you pull the clutch it takes all the pressure off the plates the clutch is going to free spin like you want it to. you just have to make sure it is adjusted right so that it lets all pressure off when the clutch is in and it has enough pressure on the plates to grab when you let the clutch out.

go to this link. there is are good pics of what you need to do to adjust the clutch http://www.blasterforum.com/engine-13/quick-clutch-adjustment-29561/ you have to scroll down but there are some good pics. just read and learn my friend

Ok, from the begining, You had it all apart so was it put together correctly, Two things come to mind, if it's not disengaging.

Take all the fiber and steel plates out of the clutch basket, Put the motor in neutral, MAKE SURE IT"S IN NEUTRAL, now can you spin the inner basket? If answer is yes, then I'd say it's an adjustment issue.

How to do proper adjustment- (Ya have to remove the cable first! And remember Fiber plate goes in first then steel, then fiber then steel... until all are in you should end up with a fiber plate in last!)

1. loosen the outer center nut on the pressure plate almost all the way off
2. hold the clutch lever (the part that the cable hooks onto in the motor) and gently push it towards the front of your bike to relieve the spring tension
3. Now with a small phillips turn the center shaft in which ever direction it takes to align the pointer marks up as you are applying a little pressure to lever shouldn't take many turns you will feel it move. [usually clockwise] Pic of arrow on caseVV (the point on the clutch shaft should point to this arrow on the case)

4. When it is aligned, let the lever go it will go off the arrow due to spring tension that's ok. Keep your screw driver on there and take your wrench 10mm and tighten the center nut down snug while holding the center rod tight so it doesn't move. (I used blue locktight on threads also)
5. Now take a socket and tighten it down good but becareful you dont overtighten it and snap it just a good snug tight is perfect. 5 ft lbs is what the manual says.
6. Put the cover back on, make sure your spring for the kick gear is in the hole when you do this or you'll be replacing some more parts down the road (experience talking here!).
7. attach the cable back up and adjust that just until you feel the springs on the pressure plate start to hit, then back off 1/8 turn and try that, ya may need to play with the adjustment on the handle bar lever as it warms up.

If you cannot reach any step a couple things to look at are, Missing ball bearing or two ball bearings accidentally put in, bad clutch lever shaft, incorrect number of plates or incorrect pressure plate placement (DOTS ALIGNED).

Is the basket grooved? Deep groves will keep clutch from working correctly. Basket can be carefully filed to get a little more life out of it. Inspect all plates closely. Even tho a BB will work, it won't last and may damage rod or adjuster as the BB is not a hardened ball.
