Yesterday 10:33 PM #1 Ski in NC   Frustrating I´m sure. If you are losing coolant without external leaks visible, then you may have a cracked cylinder head, bad head gasket, leaking exhaust manifold, or leaking turbo gasket.

Jun 30 2009 12:20 PM #27 Ski in NC   The stator slides off the rotor. The rotor remains bolted to the flywheel. The bearing on the end of the rotor is a slight press fit in the end of the stator.

After I get the stator loose, how much room is there between the stator and rotor windings to avoid bumping the windings? In stead of risking the bump, I am thinking of leaving the generator end on the block and turning the motor and ..... Jun 30 2009 03:13 PM #29 Ski in NC   If you can leave stator on, then leave it on. Just roll the whole critter on its side or whatever so you can get pan and rod bolts off.

Jul 2 2009 06:03 PM #34 Dan   Hi Eric, The manual does give specs for flatness and twist - it says use an "connecting rod aligner" to check for flatness.
