Here's another question on the B670 backhoe (and I suspect others): The swing cylinders are pressurized on the back side only. The front side is open to the air. That means condensation or whatever can build up. The end cap is drilled through to vent the air on that side but is a source for...

What a hoot. Got the rebuilt cylinder in place and the new hoses. Fired it up and began to actuate the cylinders to purge the air. When I did the bucket a hose blew. And it blew in just the right place to spray me directly. Fortunately I wear glasses. This seems to be the project that just keeps...

No Sir, I don't have the manual. I don't want to trouble you for that project but if you are available to ping if I have a question in the future that would suffice. I've had the tractor for 30 years and the backhoe for 27 and there's been very few times I actually needed the documentation. I...

Dang, thank you SO much. Its the reaction action (retraction of the cyclinder) - as if you drove forward with the bucket in a hole so you don't blow a line.

Folks, I screwed up. It took so long to get the rebuilt cylinder back that I can't recall the hose connections. There is an over-pressure valve between the operators legs. I can't recall if that was protection for the extension or retraction. I was going to diagram it but I thought it wasn't...

Believe it or not there *is* a specialty hydraulic shop in the area. In fact they opened a 2nd shop about equidistant to me in a small town and the newspaper did a BIG news feature about the big grand opening. All they really do is make hoses - from the service truck. Anything else goes to the...

(rolling eyes.) Ain't not way where we live. There is a CAT dealer an hour away but they won't screw with a Kubota. They're parts swappers and only want big stuff unless you're buying a hose or O-ring. I continued pondering a place to put depreciated implement ready for recycling. What a...

This is a curious issue. I'm sure I can find a cylinder with that diameter and stroke. But a cylinder with with that OEM yoke is a specialty as would be a threaded ram to accept the fashioned OEM yoke. Note that no break down shows the unit's threaded yoke as a separate item. I don't have...

Darned if I didn't do it again - working in a cramped space and backed into a tree in low range. You'd think I had time to watch but I had to watch the bucket and trench. But popped the yoke off again again.... Its time for a new cylinder. I looked up the part: 70050-00003 But my GOSH! $850 to...

And here is post 6. Just to be safe I always try to exceed minimum requirements. It almost always works except when the wife is involved. So here is the picture. Yeah, I slipped with the hand grinder and hit the hard chrome but it's still above the seal when retracted:

Thanks for that hint. Here is post 5 - hopefully replies count. I'll know in a moment.... (wink)

On the B219 loader you are correct. The yokes are welded directly to the ram. But for Lil Foot, the B670 backhoe is different. There is a definite rim and "hub" extending from the ram. The hub/extension is definitely undersized by a bit and not hard chromed like the ram. Boom and dipper...

I was filling in a trench with the loader when I backed into a tree. Oops - the darnest things happen in low range. The yoke on the boom cylinder broke loose from the ram. It looked like it had been welded before and whoever attempted the repair, they didn't get much penetration. Anyway, I have...

Thank you, sir, for the reply. Yes, reverse is growling but not like 2nd gear. And no problem or concern with PTO operation which I use a lot. So this will definitely be a winter time project. I hope I can coax it thru the work season.... And frankly, I should probably freshen up the...

Hi folks - my 1st post here: I've had the above referenced Kubota for many years. The hour meter was broken when I bought it so I have no idea how many hours are on it but its a bunch. I've been dreading the day but it has happened. The unit has always growled quite noisily in 2nd gear and...
