Specs At A Glance

Good To Know

Q: How do I know the crank seals need replacing? A: Common signs include oil leaking behind the clutch, erratic idle, and a lean running condition. A leak-down test on the crankcase confirms whether the seals are holding pressure.

Q: Can I install this kit without splitting the case? A: On many two-stroke engines the outer crank seals can be replaced with the engine assembled, but always check your service manual for the Z 570 procedure. Some seal positions may require case splitting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
