Hard to turn crank after assembly

[manynails]

This is the first Banshee engine I have rebuilt.  I replaced the crank bearings and seals (the large crank seal was very tight going over the crank, I did grease the seal lips).  After torqueing the case halves together the crank is hard to turn over by hand...It does turn over but much harder than other 2-stroke engines I have rebuilt.

 

Is this normal on the Banshee or should I split the case and replace the seals?

 

Thanks

it should spin freely. somethings too tight or binding, split it, start over.

Did you put the outer bearing race pins in the notches in the front of the lower case half? Are the crank wheels rubbing on the sides of the cases? Is it a trued and welded crank? If not it could be separated. Are the cases a matched set? Look on the back edge. There should be engraved letters/numbers on both halves. Make sure they match.

Problem somewhere

Thanks for the response.  I was going to split it...but...I pulled out the primary drive gear and the crank spins nice and free so the "problem" seems to be a lot of seal drag.  I had greased the seal lips and the surface of the drive gear before assembly.

 

Is it OK to have that much seal drag or should I replace that seal.

 

Thanks again.

Hopefully that means it's sealed up nice. What brand seals?

[manynails]

I used a brg/seal kit from All Balls...I can't see the brand name on the actual seal.

If it wasn't OEM or K&S it's Junk IMO.
