chaincase needs to come off. pay attention to the collars behind the gears. theres a thin one and a thick one. be sure and loosen the bolts and nuts on the gears before removing the brake caliper. brake can be used to hold tension when removing hardware.Drive shaft where the 4 cogs are. I have the 5 back suspension bolts off but the front left bolt (under the secondary) just keeps turning. How do I get that one off? Also I cannot get the snap ring off in the chaincase for the axle. I want to replace the bearing there as well as the snap ring and seal. Does the entire chaincase have to come off or just the cover to get the snap ring, bearing and seal off?
