Installing a Hydraulic Main Pin Thumb

- In his Video I install a hydraulic main pin thumb on my John Deere 240D excavator. I had to air arc the old bushings out of the stick, machine a new hole in the pin, install it, and weld on the cylinder mounting bracket.

Now I'm addicted to your channel as well.
omg - no wonder you and Matt are mates - htf do you know how to operate all that machinery, especially that cnc machine - what a piece of kit. I'm in awe as to its complexity, more so you can operate it!
Congratulations on reaching over 10K subscriptions! I’m really enjoying your videos!
You need to make yourself a press on a trolley. Mount a 50t press on a trolley with a pivot arm so the vertical motion becomes horizontal. Then put threaded rod to go through the trolley frame to the back of what you are pressing. Chain will also work to a degree. Then press the bushings out with a guide pin or pipe. If youake the outer frame out of U channel, your press frame can lift and lower to the height you require using a simple chain hoist, or ratchet straps.
Just a heads up, we made puller out of 2 pieces of 1/2” plate and 1/2” threaded rod, plate on both sides to snug up the bushing and as i tapped the plate somebody was hammering the impact on the threaded rod. Zipped them in in no time but by myself i threw the bushings in the freezer for 20-30min and took no more than a good straight smack on a piece wood and the bushing fell in.
Good job Sam!
Not bad. Last month it took me two frkn days to get the thumb, bucket and dipper holes all lined up. You did well.
Interesting story for ya, the man who invented arc air gouging lived a couple mile up the road from me growing up in Fairfield co Ohio, Myron Stepath, was his name , we farmed his farm and he loved to booze it up while driving his Cadillac around the pasture checking on his horses
An ice bath might have helped those new bushings go in a little easier.
I found you throw diesel creek 🤩
Me too
Enjoyed this video bro. Safe travels. Ken.
Thanks!
Oh yes it looks pretty pretty good a bit of a learning curve you got it in the end.
New to the fold here. Enjoy your videos very much. Thanks for sharing.
it's a little bit easier to get the bushings in if you let them sit in the freezer half a day or more to make them shrink slightly. Keep in mind that beating on them heats them up, so the more you beat on them, the harder it is to get them in.
you should consider getting yourself a puller tool, don't know the actual english word for it but it's basically wide and thick hook screwed on to a semi-thick threaded rod with a very thick handle and a dumbbell shaped weight moving freely on the rod that hits the back pulling anything stuck enough out. usually you find these in car body repair shops pulling very bent stuff that crunched deep in to the car frame
in english its a slide hammer :)
AWESOME CNC machine
You got Talent Man.🔧👍🇬🇧
We’d weld on a new threaded keeper like what’s on the thumb to the quick coupler, we noticed pins have a tendency to break and twist the ear in the thumb when they were drilled and bolted through the quick coupler, not saying it will happen with yours, but our apes always seemed to trash them
Haven’t you got a pneumatic hammer? I saw C&C used one to get a bush out and it worked great 😊
Love watching your adventures, How are the tolerances on your older Haas? I'm sure you know but X,Y and Z axis ballscrew bearings are sounding pretty sketchy. Keep those videos coming!
air and a hot stick does wonders
Gonna have to make a new control for it right
What about putting them in the freezer or dry ice in the hole?
Did you build the thumb or who makes it? I like the style of it.
I ordered it from across the pond. Just gave them all the dimensions I needed
👍🏻🍻
Hey buddy just subscribed, saw your awesome mack at the steam show. Did you used to program cnc machines before doing TH-cam or do you still. I'll try to find you and say hi this spring. Ohh I talked to Matt he wasn't grumpy like he was this past spring lol. Take it easy buddy!
Ya got that right ya push forward when air gouging good job
Thanks! I think it will be very useful
@@ScrappyIndustries it will!
And the tool isn't expensive, as you found out.
The rods will over run the tool expense shortly.
Good stuff man.
Why do Hitachi and Deere rigs always have their engine covers open?!
Curious, isn't there some sort of puller you can use to pull the bushing?
Yes, the type of puller he mentioned in the video.
Along with the explanation of why he didn't use it.
You're welcome.
Heat it and beat it!!!😉
Good job, that's exactly how I would've done it.
Thanks bud!
Don't you guys ever sleep?
You should put the bushings and pin in ice or dry ice overnight and shrink the size then install them .

Hit is with your purse!
You need a 20lb hammer bud
Hahaha I love it 😂
No doubt about it
Diesel creek sent me over nice work!!!
Yep… Matt talks about you and you’re on his channel a lot so I finally got caught up on a lot of his videos and decided to check your channel out.
Great video and not a bad weld by any means!
Thank you!
Great video. Enjoyed the cnc part, and your improvised gouger. I am guessing your keeper bolt went in well ?
Thanks! Yes it dropped right in
You don't know how many times I have done that with a stick welder and a high pressure air supply... Making your own exothermic burner Good stuff!
I came by to have a look see. Your channel give camatata a run for the money. I definitely like your toys and the way you ''produce'' the content. Like I said, I'm glad I found this channel. Keep on truckin, and you'll have your 15 minutes soon!!!(I DINNIT SPELL ANDREWS NAME WRONG ACCIDENTLY)
Hi love the channel. Buy yourself the adapter for your porta power make life easy for your self. Dry ice work wonders. Thanks for the channel i enjoy watching.
If you want to gouge with normal rods dunk them in water you will gouge cheeply.
👍🏻
With 6010 you can crank the amps and will cut out bushings- that’s how we cut out tubes out of boilers. One of the ways..
I always just cleaned out the best I could just cut with the torch knock them out clean everything up as good as you can throw the new bushings in the freezer after you got a bolt that would go through get your biggest impact you got you might have to make up your own washers just what's some good plate and drive a new ones home but I haven't watch the whole video yet
Oxy-acetylene always works the best clean the grease out as best you can warm it up on the inside and then blast your path in word so you don't destroy the boar everything will be clean when you go to put the new ones in
where did you buy then $50 arc gouger?
Can someone tell me .. what was that welding tool thing called.. a gauge... He cut metal. With a welder
Air gouger. Basically a cheap plasma cutter. Same principle.
I know you looking at the shrinking aspect of it but the heat will expand it meaning with the welder but cut a relief cut with a torch they fall
After welding around the bushing, or internal bearing race, after the weld cools, they will shrink and come out easily!!
The ONLY way to get bearing races out of aluminum semi truck or trailer hubs.
