This is a cool Vespa PX150, originally purchased in Germany. It came in with a locked-up motor.




Well lets get her apart and see what's going on... 


Motor is out 

Aha! Someone installed the critical clutch side crank seal wrong-way out!!!
 The crankshaft rides against this seal and if it is backwards eventually the crank window will catch it and hell breaks loose... note the smaller pieces, one of these was jammed in the rotary valve which stopped the crank so fast it spun out of round , the other chunk went through the cylinder, destroying the assembly :(

New seal in place.


New crankshaft and bearings, looking real clean inside!!
oooh shiny...

Might as well install a big bore kit since the original cylinder and piston were trashed.

Now lets get that rebuilt motor back in the chassis!

Time to ride out in style...
