Plumbing for a grapple

[PatMcD]

It's a 2" rod with 3.5" barrel. I'm going with 3/8" hose. The guy that builds them sells them primarily for skid-steers, so maybe that is why he said 1/2".

With 3.5" cyl then, I would go that way also. Man you could almost use that to split logs, I don't think it well let go of anything.

PatMcD;
This is how I terminated the couplers at the loader, I couldn't find any bulkhead fittings to use with angle iron so I used the "break-away" clamp from TSC.

 

[PatMcD]

The rear remotes take 1/2" AG fittings, and I think you would be fine with 3/8" hose, works fine for me.

AG fittings have a ball on the end don't they?
These are the male ends from my loader hookup:
They are 3/8, but what are they called? I'd assume they's use the same all the way around, but maybe not.

Liable to be ISO-7241-1 either A or B series.. download this chart on this page and check against what you have.

If I had to guess from your photo they look like ISO-7241-1 Series B

That kind is the "poppet" style. I have that kind also, but the round ball style will work with them. I am using the 2 different styles together with no problems.
If you can find the poppet style I would go with them, but I couldn't find that style locally.

"AG" fittings can have either a ball or poppet, and while they do/will interchange and connect together, it is not recommended.

Underdog. If you can post a pic of your grapple on bucket I would like to see it.

Here you go, that is a 36" thumb. Here is a link on the install showing it on my pallet forks & bucket...

[Bluesteel]

Thanks dog. That thumb is neat. Went to their site and looked at the different sizes they offer. May have to spring for one.

 

[Bluesteel]

Underdog. In your pics the top of your bucket is different from mine. You have the angle iron on top to give yourself a level area for the mounting plate.

 

[Underdog57]

Yeah, to get the angle right u have to modify things a little.

 

[Bluesteel]

I see they have several different lengths on their web site. You said you have the 36" is that measurement from the pivot pin to the end of the thumb? My bucket measurement from top to cutting edge is 24". Probably go with that if it reaches from top to cutting edge when closed. Obviously it won't touch if you have a lot of material in the bucket.

On your angle iron you installed did you drill and tap the holes for the mounting bolts? Or did you weld nuts on the bottom side?

Company is in Centralia, Il. which is a few ours south of me. Did not know that.

He welded nuts on the underside of the angle as I did. I have the 36" thumb also. Its a little long for using with the bucket but mainly I use mine on the forks.

 

[Underdog57]

I got the 36" model because my main use will be on my pallet forks. If your only using them on your bucket then I would go with the 24". Yes the measurement is from the pin to the tip.

I welded a 1.5" angle iron on the top edge of bucket for extra support and then a 4" angle to mount the thumb. I welded the nuts under the 4" angle.

Shipping was $115 to get mine to W. Michigan, looks like you could make a road trip and save a few bucks.

I got all my ideas for this install from TBN member George2615!!! :thumbsup:

Looks like we were typing at the same time George!

Yeah, I saw your last reply to Bluesteel was yesterday and didn't know you were online so I figured I'd answer his question about the welded nuts to mount the base plate.

 

[Bluesteel]

Thanks to both you guys. I have some business in that area the next few weeks or so. I may just stop by there and bring one home.

 

[PatMcD]

I put together a parts list for my plumbing job and took it to the local hydraulics shop. $300

I'm pretty sure I can do better through one of the online sponsors here at TBN.
