center pinning question

[Dan Reed]

Hey Allen,

No theories on why that happens...but....I have good results when 
repinning, to add Teflon to the bushing...either with the reamer, after 
reaming, or to each ofthe bushings, via the pin. I find I can 'pin a 
little tighter' and get good results...this might work with your 
situation.

Best to you,

Dan
