Don't think there is a limit.
I have a BX24 with 815 hours and when I lift and dump the bucket, there is quite a bit of slop. One day I will check and see if it is the pins or the holes in the arms and cylinder mounts.

It is probably neither, at least on my 2350 the stop pins are off by at least 1/2" which makes for a lot of slop at the buckets cutting edge when the bucket is fully curled back. What Ii did to fix this problem was to round off the stop pins a bit with a grinder, then I drilled and tapped a 3/8" hole in the ends of the stop pins. I then slipped a peace of large rubber and metal mesh hydraulic hose over the pins. To keep it in place I added a 1.5" washer and a 3/8" bolt. Problem solved.
