Me too. I even tried my cell in case it was the PC I was using.

Yep, This is what I get now on pictures that were there Saturday:

The pictures are in Sundays post:

I'm not sure why that happened, those are all my pictures, there is no copyright...

Anyway, I continued working so I made my seat turnable. Belarus has its batteries behind the drivers seat so I had to move them down under the cab. Here are the results. Now I can continue working on joystick mounts etc

 

[BFreaky]

Made a frame for hydraulic pumps, and connected everything. Also I've cut the back plate of the cab to pull joysticks through.
Hopefully I will mount the machine on to the tractor by saturday..

Could not manage to lift the machine enough with a small forklift for coupling so I decided to fix the pump in place and use a shaft to turn it from a distance. Stabilizers did the work easily

Wow, that little pto extension shaft came in handy. Got me wondering if i might ‘need’ one too. You know, just in case

I assume you know you have to slowly move cylinders back and forth to get oil in them, and not press it with full force against the end stroke untill all air is out ?

We once had to repack the cylinders of a brand new wheel loader because the new guy forced the air along the dry piston seals, creating compression temperatures like a diesel engine, burning the seals out

Thanks for advice Renze, I was aware of that. Previous bad experiences .
Vigo, it could not be done without it, that pump couples direct on to pto shaft

So...it fits







Did some short testing, it works so now I have to build a bucket for it

What is the the most common mini excavator quick disconnect bucket and attachment type there? Is it more universal there? Here there are over a dozens different types and even vary with the same manufacturer.

Modified the Kubota M59 to Kubota miniEx (8-20K #machines) quick attach. Makes changing buckets and attachments so easy. Appreciate the simple yet strong design. New and used attachments are plentiful and often less expensive. Can’t wait to see what innovations you make.

Holy crap that thing looks awesome on the tractor.

I am still itching to build the 'middle arm' for my tiny backhoe. I did buy a cylinder for the project.. and that's as far as that's gotten, lol.

Can't wait to see the bucket build!

 

[BFreaky]

Well, there are many types, probably 20-30 different ones.
Thanks Vigo.

Here in Holland we predominantly have Verachtert CW system, in different sizes. Cat bought the company, it serves the home market under its old name and worldwide markets as Cat Worktools. Traditional pin grabber couplings like you have in the States are next to nonexistent, though the Scandinavian standard, with tiltrotator setup, is taking on fast.

Yes but pin grabbers are the fastest tool changing couplers. You only need additional hydraulic line to lock it

Snelwissel CW - Verachtert

CW system too, but its built more compact, with less loss of breakout force.

Its an earthmoving oriented system: With heavy shears and crushers in demolition works, (lifting rather than pushing) it is loaded the wrong way, and sometimes the wedge cam breaks off the bucket due to fatigue. Solving this would mean altering the standard, which is not going to happen...

Thats why in demolition, OilQuick is gaining popularity, though it will never fully replace the CW standard in Holland: CW standard is more than 45 years old, older than any other standard.

I've welded my front pin on the bucket, and rear one gets inserted all the way through the bucket and coupler. This way even if my front hook snaps rear pin will hold the bucket

You finished it just in time for your Christmas present! Merry Christmas!

Are there no used cheap buckets over there you can do a weld job on? I see them here at different auctions.

 

[BFreaky]

Even if there are I'm going for the 4 in 1 bucket
