I bought a 753 Bobcat with quick attatch pins and they were not used in quite a while and are rusted in. Any ideas on how to get them loosened and working. I tried heating them and soaking them with WD40 penetrating oil.

Have you tried greasing the pins? There should be a grease zerk for each one. Look on the outboard side of the Bob-tach. The recess may be filled with dirt covering the zerk. Grease until grease squirts out the top or bottom. You may also want to try a better penetrating oil, I like Kroil. Pressure wash any dirt and crud away first and maybe the oil can enter the pin hole better. Good luck.

Thanks for the info 500K_773. I will try that approach. It is really rusted in tight. I want to get them loose and sandblast, clean and paint the Bob-tach. I am really impessed with the 753 so far. It reals operates smooth compared to my older Gehl 3030 Hydracat. Any other information you can pass on about the 753 I would appreciate it.

I do take it that you are talking about the pins that poke out of the bobtach to hold the bucket on? not the pivot pins holding the bobtach to the lift arms.
Don't quote me, but there are also nylon guides on the side of the pins. After you heated it you may have melted them, so make sure you replace them, they are cheap. The only other thing i can think of to remove them is to lift the bucket so you can access the pins, release the levers and hit them upwards with a copper hammer. Do one at a time, you don't want to knock the bucket off and have it land on your head!. Once you break the rust you should be rite, grease then lock that side down and move to the other.
I hope that made at least a little sense.

I assume you are talking about the verticle latching pins ?? If so, clean as much out as possible, beat the sides with a hammer to knock the rust out, heat them up with a torch, and while still warm, spray some PB Blaster on them. It might take a few times, and a pipe, but the blaster will work in there. They make a pin kit for them if you plan to take the bucket off a lot.

If that fails, use a bigger hammer *evil grin*
On a side note of this thread, has anyone had any success of repairing wear that you get between the pin and the base of the bobtach? i have found that on my machines i have wear on the base of them that allows the pin to move and in turn allows a bit of movement in the bucket. You can't get access to weld and grind this area....

Thanks for all your help. I am talking about the vertical pins that hold the bucket on. Someone never used these pins evidently for a long long time and they are rusted bad. I may even have to cut them out and get new pins and bushings. I heated around the pins some last night with a propane torch, not getting it too hot and had no luck yet. The other thing is where could you get a good deal on a new Bobtach attach system if this one is not useable?

You really need to use an oxy/acetylene or oxy/lpg torch, straight propane just isn't hot enough. You need to get it quite hot, you need to heat inside the bobtach where the pin goes through the bobtach, not just the pin.
I think you would fall over if you found out how much a new bobtach is from bobcat. Unless you can find someone who wrecks bobcats. I would do my best to get the current one working again before i would consider getting another one.

I suppose you are right. That is very expensive from Bobcat. I would try to find a used on or build a new one. I will try the oxyacetylene and pound away! Also, do you know of any inexpensive bale spears for round bales. I am looking for one with two prongs to use also as a forklift fork. They work great!

trg753 There is a guy parting out a 751. Don't know if he has the quick-tach stuff or not. I have his number, but am reluctant to post it. If you want to email me direct with your phone number, I'll call and we can discuss. Alternatively, send me an email and I'll shoot back my phone number and you can call me and we'll discuss. ---Bob [email protected]

Bob, Is your email correct? I keep getting back undeliverable. Thanks, Tom

I just went through this yesterday
What I did was used some rust buster.
Lifted the bucket up and tilted the bucket down where you can beat them a few times with a sledge hammer, it worked like a charm, no damage to the pins whatsoever.
I don't think the person I bought my 753 from ever took off the bucket and the pins were rusted in place. Now they move nice and easy
