Kubota Top Link Bracket part numbers

hayden · Feb 8, 2002

I'm making this a new post to hopefully make it easier for people to find in the future. The attached image is two pages from the Kubota 4690A Backhoe manual showing the diagrams and part numbers for the reinforced top link brackets for most late model tractors.

Have fun

/w3tcompact/icons/hmm.gif None of the numbers match the one I put on my 2910.

Bracket part #70050-94557.

Mine must be the new and improved number $$$$ /w3tcompact/icons/shocked.gif

Humm, maybe the old part has been superceded. Regardless, if you attempt to order the old part the superceded part number should come up.

Pure speculation on my part, but I've noticed that the bracket on the B2x10/B2x00 series provides a more narrow slot/gap for the top link as compared to the original factory bracket. I've even found some top links that required some nimor grinding to fit. It wouldn't surprise me if they fixed this and substituted a new part number.

Can you measure the gap on yours?

The gap is 1 5/8" on my B7500.

I just noticed something a little strange. The bolts for the B7500 (actually all the current B series), are half metric and half english. What's up with that?

The lower two bolts are 3/8-24 x 1 1/2, and the upper two bolts are M10 - 1.5 x 35. That must make wrenching one of these a bit of a challenge....

GlueGuy,Thats because the ROPS is made here in the U.S. and the rest of the tractor is made in Japan. Look at the U.K. web site for Kubota and the ROPS are different for the same tractors here in the U.S.

The width is 1.645". Top link has about 1/8" clearance.

GlueGuy · Feb 9, 2002

Ah. Hadn't really paid attention, but you're right, those lower bolts go into the ROPS structure.

That's kind of amazing. Here we are in 2002. All car manufactures build in metric, the tractor is built in metric, but the bozos in hoboken are making the ROPS in english. You'd think that Kubota could just specify the bolts, etc. to be used..

Hayden,
The parts breakdown is very much appreciated , it includes some items that most of us would have had to make ourselves but since we now know all the info we can order it ready made.'
Many thanks

Peter,

Just wanted to say, "Thanks" for posting the photo. It got me to thinking about this topic more and I wound up ordering the three pieces from Carver's. The parts came in today and they do look just like the photo! The people at Carver's were very good to work with. I basically wrote them an e-mail telling what tractor I had and asked them to call me for the card number. They had a good price too.

Now I have to wait 2 days before I have time to install it.....

You're welcome and best of luck. Kubota doesn't make it easy to find them since they are burried in the backhoe manual and do not show up in the tractor parts book.
