ROPS Hinge Pin Tight Fit

[bcs001]

One of the nagging problems I have to do something about in the near future is the almost impossible tight fit of the left and right ROPS hinge pins. I have to drop the bar to fit in the garage for now until I can build a taller storage shed.
I’ve loosened the bolts but have to use a hammer and punch to remove the pins and then hammer them back in to reinstall. Appears to be a small misalignment in both pin holes so drilling them out seems to be the only solution.
Anyone else having this problem and come up with a fix? If drilling, they need to be large enough to then repaint so they don’t rust to the pins.
Thanks,
Bruce.

You could use a tapered reamer to enlarge until you obtain a lose fit.
Enlarging those holes would not lessen the the ROP protection.

Kubota uses a similar setup. Following offered for what it is worth:

The ROPS are made in Kubota plants in Georgia, not Japan. ROPS fittings are inch standard, not metric.

The factory bolt is 5/8" X 16 threads per inch (fine thread). 5/8" bolts are easy to find but are usually 12 tpi, (coarse thread). If you find a 5/8" X 16 tpi thread bolt in your local hardware store it will almost certainly be Grade 8.

5/8" X 16 tpi bolts are always available on eBay.



I replaced the two factory ROPS hinge bolts with 9/16" X 4" clevis pins.

These are perfect length. Hairpin clip goes in hole #2.



Note: One of the "cup holder" type bays on the operator's console has a channel cut on the inner side, so two ROPS bolts will fit in the bay with an inch of the bolts and perpendicular hairpin clips protruding through the channel.

Mine is kinda tight too (3520h).
One pin is fine, the other I always use a punch and hammer.
I'm interested in alternatives but I only fold in my orchard and I have a toolbox with the stuff to handle it on the tractor, so for me it's not a big deal.

Both new Bransons I have owned had this problem with tight rops pins. I grind the pin on the bench grinder and it's fixed.

Do your pins not rust after exposing the raw steel?

I know the OP puts his ROPS up/down often so tight pins are a pain....I get that. But, I really hate loose rattling stuff on a tractor making noise every minute you are operating it. If it were me, I would be careful on getting it too loose.

Take a Rat tail file and file the holes a bit. Easy-Peasy.

Just rub a little grease on them. It is a tractor, correct?

My pins work perfect. It’s the knobs I have to turn almost off to get the ROPs up/down that are a pain.

Forget to tighten and they are lost. I had to tie them to the tractor like when your mom used to tie your mittens to your coat sleeves.
