Enlarge category 1 sized holes to accommodate category 2 pins.

[stumblinhorse]

Have a new to me large heavy 3 pt implement. My Case is cat 2. The top link holes fit the cat 2 pin but the lowers don’t. Definitely cat 1 sized. There are 2 sets of holes for pins. I hate the sleeves since they often times slide side to side and are a nuisance it get on when attaching. I am thinking about enlarging the holes to fit the cat 2 pin diameter. There is plenty of material to take 1/8“ or so that is needed. Width isn’t an issue so any advice?

wouldn't be easier to just tack weld the sleeves in place on the implement
i have seen replacement balls that fit into the lower arms with different size holes the ones I have seen were to go down a size but probably available going the other way as well

I have a quick hitch that uses cat 3 size pins.
On my implements I have replaced some of the pins with cat 2 and tacked welded the sleeve on. The other pins are cat 3. They dont bend like the cat 1 does.
Enlarge the holes snd put the bigger pins in.

It's always been easier for me to switch a few pins. Easy for me to say now that my remaining stuff all Cat-1 (3 CUTs) so it depends on which implements are used on which tractor(s). That or I'm just tired and I apologize ...

I converted an implement from cat 1 pins to cat 2 pins for less than $20 and very little effort by buying this product from tractor supply company:

it is the type of attachment where the arm is between the 2 holes per pin. You have to put the sleeves in the arms lower the arms and then put in the pins.

Definitely leaning this way. All my cat 2 implements work the same with 2 sided connections with a pin that slides thru. I guess that is because they are all over 1500 pounds each.

With that much metal to spare I would drill them out. Sleeves are a PITA. Quicker than welding in the sleeve.

Or used replacement lower lift arms are also out there for reasonable prices.

Bore the holes out, one of the stepped bits that max's out at 1 1/8" will do a nice job.

I used a stepped bit to start the hole enlargement then used a hole saw to finish on some thick pieces. Worked well.

you guys are far more creative than me, sounds like a risky thing to do as the machines are built with specific design and purpose. my mind goes not to adaptors and creative solutions etc, but to liability issues and voided warranty claims.

just because it can be done ... should it be done ? I don't know

I am not a welder / fabricator, but I guess I was a government employee and occupational health and safety agent for far too long.

perhaps I've been stifled beyond recovery

Or weld on cat 2 ends on the tractor side of things. I'm about to weld a set on a 510 LONG in a few days. Already bought the new ends. Then I'll be cooking with grease.

What if you have a used cat 2 machine that someone already replaced the lift arm ends with cat 1 replacements? Is it okay to put it back to the original cat 2 that it was intended to be? I mean, it already has some junky dirt dobber welds on it as things are now.

Fair Point - but I think that that is the equivalent to restoring to original, rather than modifying / adapting to a new level. Either way, I don't weld etc, so it won't be me. I don't think that would void a warranty though, or push it beyond intended limits. If you have the skill, go for it

Warranty? I keep forgetting that some people have new stuff unlike the old stuff I have.
I worked in health and safety before retiring. I understand all too well the mindset you develop in that field. But thankfully I started out being a hardheaded weldor.

So I just enlarged 1 side and used a stepped pin. All about compromises these days .
