Backhoe Added a ripper to my Woods BH90x: Trees beware

[IslandTractor]

Yeah, I kinda chuckled when I typed that, but thought, "Well, he probably deserves it."

Yes I have felt that way.

The practical problem is that the ripper must be below the BH so it is hard to rig a way to suspend the ripper without getting tangled up in the BH.

The main pin is the b@itch as it includes the thumb.

That's a downside to pin-sharing with the thumb, and it explains your
struggle. Changing bkts is no fun, but I do not have nearly the problem
you do. I can also rock the bkt small amounts using my hand or foot on
one of the teeth to get that tiny bit of movement to get the pins in. The
bkt rocks on the floor on its curved outer surface.

If you keep the outer face of your ripper tooth curved, you can do this, too.
If you weld something bumpy there, no way.

Yes, the bucket is much easier as it sits in a stable position and as you note it can easily be rocked or nudged. The ripper is only stable when upside down so requires balancing at the same time as manipulating to line up pins. It really would be a great torture puzzle.

Today, I stopped by my local hydraulic shop where I had my grapple hoses built. I brought up the problem I was having aligning the ripper tooth, hydraulic thumb and dipper stick holes to pin them together. I left with a blessing from the scrap box, straight with no dings an 1-1/2" x 12" chromed hydraulic cylinder rod as a "new years" gift. Home made alignment tool question:
I'm pretty good as far as shaping/tapering using my grinder and hand files.
I know no-one with a substantial metal lathe to make the taper.
Pay to have a shop lathe it down or do it myself on the grinding wheel and further polish by hand? I have the time but also need this problem to go away forever.

It would certainly be easier with a lathe. I imagine a skilled machinist could taper that rod in 20-30 minutes vs hours with a grinder. A lathe would also give you a true round taper. I know I couldn't come close to round with a grinder and no lathe. Round really would be helpful so if it were me I'd certainly track down a machine shop and see if they could do it for a reasonable price.

I think I'll dink around with it, making sure that I don't harm the backhoe's races with rough edges. If that doesn't work, I'll take it back to the hydraulic shop's scrap bin, toss it in and retrieve another 1-1/2" rod that will be destined to a metal lathe.
Just quickly looking on line, I have only found alignment pins up to 1-1/4" diameter for around $25.00 which seems reasonable but I need one that is 1-1/2".
Leaving the suburban madness tomorrow for a few days-retreating to our mountain digs-will check back then.
Happy New Year All!

Those McMaster alignment pins are a lot less expensive then what a machinist is going to charge you for 30 mins.

Alignment pins? Are those different than the spud wrenches? Sounds like what I need.

Dude, my post number 223, click on the link, bottom of their page.

I pound it though with my mounting pin following as I mentioned earlier.

Thanks.:ashamed::ashamed::ashamed:

I have mostly been reading my posts with my iPhone and had trouble opening the Carr McMaster site so didn't see the alignment pins. That is exactly what I need (until MIE comes up with a quick coupler). Now I just need to figure out what the pin sizes are. Tractor/BH is asleep for the winter and a couple of hours away.

Anyone recall the diameter of the larger pin on the BH90x bucket: ?1 1/8" or 1 1/4"? Bigger??? Maybe I can find it on the web.

Thanks again for the repeat heads up on the alignment pins. Happy New Year.
