So after experimenting a little today working out the movements on the bucket with the 1/2" longer arms, I determined the length of the conecting rod from the bell crank to the bucket needed to be lengthened 1/2" also. This worked well through out the buckets movements except when in the full up position and bucket dumping. The center pin location on the bucket for the connecting rod was just about on the same plane as the pins for the arm attachments point on the bucket. This caused the movement of the bucket to bind when turning up from the dump position. I employed the use of the printer and mocked up a connecting rod and block to try different pin positions on the bucket as i knew i had to raise that connecting point up above the arm pins to fix the dump bind.
New mount .400" higher center to center pin location. All up and down movements are smooth with no bind now.
New solid connecting rod.
Arms full up , bucket full down
