gx 390 crankshaft problem

[ppea]

I have a problem with crankshaft bearing from crankcase cover.The crankshaft on the crankcase cover side has a play in to the bearing.It seems the crankshaft has a very little wear.It's normal or i have to replace it? The crankshaft it's ok to have radial play?

How much play? You can grab it with your hand and wiggle it noticeably? Probably a bad bearing on one end or the other.

Never seen a worn driveshaft, that's the purpose of the bearings. Have seen some bent ones, but not in a GX.

If i grab with hand and wiggle it hard is knocking.When engine is runing after a few minutes the knock is more pronounced.the bearing is enter very easy on to the crankshaft.

i found the problem.It not was the crankshaft or the bearing although they have signs of wear.It was a washer missing from the underneath of the governor and governor doesn't work corectly.
