My BCP has been having alot of head play lately... (quit snickering)....
I've been rebuilding it and have found the following.

The shearpin hole in the main shaft is larger than my shearpin. The mainshaft and gear are new. Is this normal, or do I need a new shearpin?

The other thing I've noticed is that the hole in the center hub that the blade grip spindle goes through is oval in shape. The oval extends vertically (up and down), not horizontally (side to side). Is this supposed to be like this or could this be another source of my slop?

Thanks in advance guys,
