Crank Seals

[Woodsie]

Anybody know if you can replace crank seals on a YZ125 without splitting the cases?

You have to remove the flywheel(with flywhell puller) and stator for the left side, and the water pump, clutch basket and main gear(on end of crank shaft). You could probably use a impact gun to remove the clutch and main gear. I srewed a couple of wood screws in the old seals to pull them out and used a scocket to push the new seals in. Just make sure to install them to the correct depth b/c if you push them in to far it will block a little oil passage and it will wreck your main bearings. Check with your local dealer for correct depths. My 97 cr250 was 1mm on right side and 2mm on left side. hope this helps
