how do you go about flipping the clutches on the za50?
pop out first gear clutch, flip it around, put back on. VERY SIMPLE. you must remove clutch cover first.
WTF why do i have to remove clutch cover first???just kidding thanks sounds simple....if only i could get on the ball and get all the damn old effed up bearings/races out of my case halfs and crankshaft!! thanks again
Actually, you flip the second clutch... as in the one mounted on the start plate - aka - the clutch that's under another one. Flipping the first speed gear would just keep you fist speed clutch from engaging, revving your engine higher before you started moving. Flipping the second speed clutch makes it harder for the second clutch to spring out, and therefore stay in first longer... Don't believe me, believe this thread (paz approved!)...
If you still have your original pucks in your engine, flipping the second speed gear is going to be harder on those pucks, because the engine is going to hit them a lot harder when the second clutch engages - possibly causing them to disintegrate... cascade effect. AHHHH
right, so as long as you are in there, switch out the stock pucks with the motion left pucks
oops. yes only one of the two clutches can be flipped anyhow. ok second gear.
I tried this at home the other night. It's seemed pretty easy.
I think all you have to do is just put it in with the triangle side facing the inside of the engine, opposite of how it is demonstrated in this video:
and be extra careful to put the shims back in the exact same place you found them.
hey, i recognize that video! ;D
this is something I've thought about doing, but never tried. let me know how it works out for you. my biggest issue with my stock clutch is that it shifts before I can even pull out of an intersection. i'd love a later shift.
i'm actually going to be doing some clutch work tomorrow anyway so I may just try it out while i'm in there to see how it feels.
Yeah man! Your videos are a huge help!
I tried to change my shift dampeners the other night using the technique you demoed in your videos. Still no luck though. I even bought a huge ass flat head screw driver and toasted the crap out of the screw backs with my Bernzomatic Fatboy. I'm going to use my bench vice next with an impact wrench. Wish me luck.
careful with an impact wrench. i wouldn't know where to send you for new screws...
but definitely good luck. those things were TIGHT in there.
also, if you're using a bench vice be sure to clamp the shaft, not the teeth. that should probably go without saying, but i'd hate to see someone shear their teeth while trying to replace their pucks....to keep the teeth from shearing in the first place.
best of luck!
let's hear how it turns out.
I just opened up mine up tonight. You should get an impact driver, a hammer and a vice.
Set shaft down through the vice, with thin wood blocks on either side and torque it down with the actual gear reasting on the top of the vice. Then go to work with the hammer and driver.
Worked like a charm!
its nice to see wider acceptance of the za50 lately. I think most fears about then are unwarranted. Its a well designed motor that can easily handle power if its all together properly.
Yeah, that's what I was thinking of doing. I'm definitely going to clamp the shaft (i think that goes pretty much without saying). I'm going to use MDF to shim the shaft (should be soft enough.) I might even shim under the gear so that when I bang on the screw heads there is something there to absorb the shock (like a cloth rag or something.)
The problem that I had with a screw driver is that most all screw driver heads are too narrow for the slots on those screws. I even bought a new screwdriver and Dremeled to head down till it was wide enough to fill that screw slot pretty snug. I still could not get them to pop, even burning the crap out of the screw backs with the torch. I've probably melt the loc-tite, but I think the metal of the screws is expanding more than the inserts, which is making it still too tight to turn by hand.
The flat head bits on my impact driver seem pretty wide; wider than a standard large flat head screwdriver with a 3/8" wide head (the largest I could find at several hardware stores.)
I'll try and video my process. I'll at least post pics and a description on my blog.
I would be careful as to what part of the gear you are putting in a vice grip. Put it on the bottom portion of the second speed gear that spins the front sprocket. Put it on THAT _shaft_ and not the gear. Definitely DO NOT clamp the longer smooth shaft. There are roller bearings on the inside of the first speed gear, so that longer shaft should essentially be thought of as a bearing race. DO NOT CLAMP IT.
So, instead of melting everything and what not and using an impact wrench, I would go about using a breaker bar, torque wrench or screw driver and chanlocks only because there are spindles underneath that plate that the pucks stop against and I wouldn't want to hit that gear so hard it bent them... it's not solid metal. You can get new screws btw, you just might have to got to a screw and bolt shop, cuz it's metric with that weird sloping. ok... so getting the screws out - something like a 3/16 socket will accept those little phillips and flat head bits you use in screwdrivers that have lots of different heads. So, if you have a socket with the right size bit, then you can mount it to a breaker bar or torque wrench. The chanlocks and screw driver thing is self explanatory...
Don't forget to loctite the screws when you reassemble for great success...
Did it! Impact driver worked like a charm! MDF shimmed everything. 3-4 hits per screw and I all was golden. I'll post photos of my set up soon. I took videos as well. What a breeze!
Grinder - Yep, you did!
