Pin diameter for ROPS and 3 pt sway bars.

[thoner7]

Anyone know the pin diameter for the foldable ROPS and 3 pt stabilizer bars?

The ROPS on my m5400 is really close to 3/4". the holes may be out of alignment, causing them to be really tight. But I assume it's metric(?) And maybe I'm just a hair too big?

I haven't looked closely on the stabilizers but those are missing on my machine too and I'd like to order some soon.

Cheers

If 3/4" fits too tight, then it tells us that 20 MM wouldn't work either.

So it's 18 mm or M18x2 if it's a bolt.

High time to add your KUBOTA to your T-B-N PROFILE.


Current Kubota ROPS are manufactured in USA and are inch standard.

You can order almost any diameter and length of clevis pin from eBay venders.

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.

After you hit your garage header a couple times, plus a few tree branches, the ROPS will vary a few 1,000s, so the pin holes will not line up.

On the front of the ROPS there is a welded on nut on each side, there so one can insert a bolt as a stop, to line up the ROPS pin holes perfectly. Welded on nuts on the front of the ROPS take 3/8" - 24 thread per inch (fine thread) X 1" bolts to align the ROPS holes. Tight fit the last 1/8", probably due to paint in threads. Turn well lubricated bolts with a wrench the final 1/8" during first insertion.

Tractor Supply Company (TSC) has 3/8" fine thread bolts NOT in the bin section, where 3/8" coarse thread bolts are, but in the Grade 8 drawers, in two-bolt packs.

As stops will seldom be moved I suggest lubricating bolts with anti-seize compound.

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.

Actually I guess I was wrong. 3/4" is loose. 7/8 is what is just a hair too tight. I could hammer it in but it wouldn't be a quick-change kinda thing.

The machine is a 1998 I believe. So maybe back then it was mm? Or should it take 7/8??

Wby are you so concerned with having this pivot tight?

Use a 3/4" pin.

Most current Kubotas have a pinch-bolt behind the pivot which can be tightened/loosened to adjust ROPS fold friction.

Sometimes it is nice that the rops pins are tight as they rattle less.

I'm not actually certain a 7/8 bolt will fit. I figured it was a mm hole.

What about the 3 point stabilizer bars? Are those 9/16 or so e random mm???
