i just got my 350 together and it was a little hard to move the crank so i just kind of started to assemble my motor and one i got the sides on the crankcase on i went to turn it and was like it was seized. i was told that the endplay was off. what does that mean. and how do you adjust it? any info would be great.

 

i would make sure your crank seals are seated properly this could make it hard 2 turn it over

 

it turns hard without them in though. first i greased the seals then let it sit with oil in it i came back and it was the same to ,i removed the seals and still the same. so what do you think is wrong?

 

i thought you were still taking it apart? lol
im kinda confused is it tight with one or both case halves on? did you replace the bearings?
need little more info, then i can help u more

 

well i said ill try it tomarrow but got bored and went out to the garage with a friend got it open like you said with a tourch and heating up the bearings, cleaned it up really good. took a good look at what needs to be done then i started to put it back together and thats when i noticed it was binding up. the bearings are all in good shape...........................sorry might be a dumb question but im still learning but what are case halves?

 

case halves are the 2 sides of the crankcase. did you by any chance have the bearings off the crank? also, make sure they are completely cleaned out if you are not replacing them.
