some bottom end questions
kwakman:
crank seal/bearing area can be repaired by machining and then being hard chromed.crank has to be v bad (worse than yours) to be completely scrap. :-D
Goat:
When you are ready to buy bearings try to find a local bearing supplier. I have a place called Joint Clutch & Gear. They build drive shafts from scratch and carry all kinds of gears, u-joints, and bearings. I saved about $100 going that route instead of getting Kawasaki or Aftermarket bearings. Just make sure you get "High Speed" bearings or they wont last very long. There are numbers etched in each bearing on one or both sides. If you take the old bearings with you they will match them up.
A local machine shop should be able to fix the bearing surface on your crank. I've seen much worse that have been fixed and worked good.
tschisi:
I?m still waiting for my crank to be pressed out of the right case and the halves to be separated. :-(
My shift forks are in spec, there are just tiny spots on the "guide pins" that are out of spec if i measure exactly there.
Btw, another question that i already know what you?ll say:
Can i just replace the rod bearings and pins, and keep the old rod?
Goat:
I recommend if replacing the lower rod bearing you might as well replace the rod. Bearings will create their own groove and putting new bearings in an old rod could cause problems in the future. Always better to do it once as it will save you money and down time if the rod or bearing gives out in the near future. Which equals more ride time.
tschisi:
I?m thinking about buying a tool for pressing the case halfs together again.
Such as the tusk cse splitting tool shown on the youtube RockyMountain ATV MC clips.
Unfortunately i can?t find it in european eb*y.
Do you just press the cases together with a hydraulic press or do you use special tools?
I heard the crank can be bent when just pressing the cases together, and not "pulling the crank into the case".
