power valve problem?
« on: February 12, 2008, 01:53:50 AM »
took my powervalve apart thought i had all the pieces out but left the (main valve rod) in now I'm trying to take it out and it slides free until a point and then will not come out anymore.any ideas on how to take it out?

*good tip i got from jeeks: use permatex gasket remover to clean the powervalve housing and parts. its a no fuss operation just spray it on let sit for 5-10 min and rinse repeat till chromed out. now my parts are shiney. this stuff is very caustic ie:eats rubber gloves and clear the sinuses right up. i found it at a local autozone.*

The hole that part is in is most likely filled with splooge.  Spray some brake clean, WD40 or anything to work the piece out.  You can even twist and turn it with some pliers.  Just be careful and wrap the end with a towel or some tape or something.

You have the two side valves out right?

Spray in here.  The last bit of the shaft is covered in gunk so it wont pull out cleanly.  The spray cleaner will help.

That rod runs off of the top gear on that side valve.  So that valve needs to be removed.

Check the other two referenced locations for small cracks.

Naaah.  Get all the pieces together and examine them closely.

Sounds like something in the PV got stuck and some gears got chewed up.

Take some good pics for us to look at.

jeeks you guys are always right. basically all my pv gears are defect in some manner. right now i'm having camera issues ( it eats batteries like a fat guy eats cake.) that and i'm still trying to figure it out (cannon powershot). so i should have some pics after school tommorow. thats all i do college-project-project-college-project-project-project. i have a new theory for myself " i'll always keep a project bike in the lineup so i can continue learning about what makes the cycles tick. now if i could only gather some greenbacks for a new klx450r a.k.a woods weapon. i'm sick of not riding

You may want to look into replacing a few of those parts.  The teeth on the gears look a tad worn.

 there was a Allen screw there i just didn't put it in the photo. that washer i believe is from the actuating arm. I'm fairly sure that it came from the power valve, but i got a lot of bolts and nuts laying around so I'll have to check the manual when i go to install.
