hey everyone.
well, its that time of year again. time to get ready for the new season! hooray!. anyways, i had my piston off the other day (puch maxi) and i noticed that the bushing that holds the wristpin to the crank arm is off center. the little brass bushing is so off center that you can see through the little oil hole cut in the bushing.
so, i tried to push it back in but just managed to mess it up a bit. any suggestions? will this pwn my bike if i leave it like this?
thanks everyone!
a little background on my bike:
70cc parmakit
homoet 4p
dellorto 15mm sha
wont idle. i have airleaks and stuff but i can fix them. tried all kinds of new gaskets and silicone and all that shit.
bump
no one has any help for me?
you say ea50.... do you mean ZA-50: or E-50,anyway i would take it out and replace it w/ a roller bearing...
Also, that is not the crank arm which you are referring to.
e-50
im a dick
i give up
ha
Benji at treats has new bushings for the top end of the rod..
how do u install new one with out destroying them like i did?
hot/cold?
press?
press
yea if you dont have a press, how do you get the old one out and put a new one in? just found out mine is worn down to the point where the wrist pin can move about 10-15
long bolt w/ nut 2 washers, a socket to fit the bushing but small enough to go trough the wrist pin hole and another socket to fit around the other side of the wristpin hole .. assemble and tighten bolt till pops in or out..
Since it's partially out chase it out with a new bearing, C-clamp or 10mm bold method.
Order a couple one for practicing. Don't forget to drill the oiling hole and clean the burrs on the INSIDE
