[wolterkj]

i just pruchases a Jiger I am starting to take apart. The clamp that hold the sprocket onto the axle. Any idea what it is called? And how might sell them?

Also is this common to another type of 6x6?

Is the hydro different from a regular Jiger? if so do you mean the flange with the small pin rivets covered with the rubber band?

Page 34 on the 197 manual may help. For replacement your best bet is to get some new sprockets and weld to a new coller.
