751 bucket pins

[redfish1]

I am getting some side to side movement on the bucket pins (if i am calling it the right parts) and somebody was saying that i could take a come-a-long and pull both of the forks together some and put washers on the outside of the forks, in between the bolt head and the spacer and tightend it up and it will take some of that flop out. Well, i have got the come-a-long so tight now, that is seems like it is going to break and still no pulling the forks in. I did put a couple of washers in there and it does not seem to be making any difference. Am i doing this right or is there a different way to do this?

No no, you want to put the spacer between the bobtach and arm, not the head of the bolt. You will need to remove the grease nipples from the lower bobtach pins to allow the pin to push in. Loosen the bolt a few turns and give it a good hit with a LARGE hammer to get the pin to break the seal, its a taper into the arms, and quite tight!. Push it into the bobtach and install a washer to take up the play. I would do it so you took out the same from each side. I used nylon cut to the correct width on mine.
Remember, you want the spacer between the inside lower arm and the bobtach (the part that tilts back and forth).
Does that make sense?
If it doesn't just yell, I'll take a picture.

Tazza, Thanks for replying about this because putting the washers on the outside of the arms just didnt seem to do anything. Do i still need to put the come-a-long pulling the arms in or do i just need to leave it loose? When you say nylon cut, are you using some kind of a nylon washer? Thanks for the help. This is the coolest forum for new Bobcat owner. Oh yea, The person that told me to put the washer on the outside of the arm was a young kid working in the parts dept. at the local Bobcat dealer. Thanks again

Just leave the arms loose. The nylon i used was like a nylon bar that i machined to the corect diameter and hole in the middle. I then parted it off to the correct width to take up the play.

I have used a steel washer on each side of the bobtach to take up the play between the arm and the quick attach, with no problems. Grade 5 washers often are somewhat random in thickness, I used one for a 1” bolt and ground the hole out to fit the pin. I took a little persuasion to get the final one in (maybe .050” too tight), but it worked fine.

When I worked at the dealership we stocked steel washers to shim with. As long as there are no cracks or breaking welds on the arms you should be fine with either, steel will last longer than nylon if you use machine a lot.
