I have made a couple of scans from the parts book that I have so you can see the two different types of drive sprocket; the later one is the one with the seals that fit in each side of the sprocket.
As I say I will talk to Tony when I see him he does have a spare drive sprocket or two but without speaking to him I can't tell you exactly which machine they are off?

Jag hade själv en 580 BT och fick då fram att det som skilde mot 580 B var just T:et som står för Tractor, dvs.de modernare larvbanden av ``bandtraktortyp´´
Jag hade också platta rullar, så jag började enligt instruktion med att dela dem tömma ur olja svetsa på och svarva fylla på ny olja och montera.
Tills jag insåg att det var samma rullar som till ett stort antal andra märken och att de inte kostade mycket nya..
(Bara en massa bortkastat arbete.)
I och med att det verkade som någon typ av standardmodell så är det kanske inte omöjligt att ``uppgradera´´ till nyare larvband.

Hmm... I have the undercarriage as in the first picture. But when I took apart my sprocket, I had those seals! And the 580b I took apart this weekend also had those seals. So it seems that someone might have changed the drive sprockets on my machine earlier.
Not much to see in this picture I'll attach, but the seal is on the upper left in the picture.
And for some reason, someone seems to have welded plates in between the sprockets on this side. :D
This sprocket is from the machine I took apart this weekend. The shaft is stuck as hell to the center of the sprocket. :( hopefully a great dose of wd40 and the big sledgehammer will do the trick.
As you can see the teeth that grips into the track is almost gone. Worst case scenario is that I'll have to weld replacement teethes onto the sprocket... Bild

Hi there :wave: I spoke to Tony Flint today and he informs me that he no longer has a spare tumbler sprocket so I am sorry that I cannot help you with that, he says that a welded repair is the best way forward for you, it may be worth your time taking the sprocket to a small fabrication company who will not charge you lots of money to repair it. Best of luck with it please let me know how you get on with it?

Ok thanks for checking. :)
I think I'll try to repair it myself. I got some material I think I can weld on.

As you al can se in the first pictures my machine missing a lot of plates and covers.
I have find a guy that sells parts from a 580 B.

I thinking about buying engine hood and al the covers over the pumps and valves.
Also covers over brakes and drive chain.
And i need the brake pads for one side and one drive chain.
And 3 upper rollers and maybe some underrollers (haven't check the underrollers yet)

So my questions is.
That parts fits my 580?
How to changes rollers?
I also need new hydraulic filters. There do i find these to a good price?

Hi. The brakepads looks very similar to the ones on the "new" undercarrige. Check with Petterssons i Gävle 026-105295. They have a lot of knowledge about Hymac.

If its the same hydraulic filters as it is on my 580BT. Here is the numbers.
