Been working on the D7 lately and now about to replace the tracks. This machine was in a terrible state when bought but is now starting to look okay. Mechanically it is quite good with only relatively minor work needed on the engine, clutch boosters, oil changes etc.

I'll be fitting better chains and trying to deal with a broken recoil spring. Typical complications are the presence of weld everywhere - something I've had to deal with each machine I've had. Must be an Aussie thing to do- weld it mate, she'll be right😉

Couple of photos...

Eric,
I am getting worried, you are spending all your money on these old tractors and wont have any for our trip through Russia next year.

Where did you get the sprocket rims and how much.
I tried to source some of them a while ago and couldnt find any.

Is that a D6 winch on that unit?

When you just use clamps to put new sprocket rims on it does not matter what you use!

It's a D8N 2 speed winch which was fitted from new and was originally adapted to this tractor for Government use i think. I'm not sure if this is ex Antartic or ex Roads Dept. It has orange paint underneath which appears to be the same as that used by the Roads Dept or could be ANARE. In any event one bloke that used to own it said the winch was always on it.

Luckily the sprockets came with the machine - at extra cost - about 600 each. I looked to convert to segmented units but could not get any locally hence fitting the weld on.

I was told Berco had them still available.

I just spent 2 hours welding on the rim. It has less than one eight concentric run out and less than one sixteenth buckle. So I'm happy with that. I only stuffed up one spoke by cutting it a bit short otherwise it all went smoothly using 20x3mm low hydrogen rods at 140amps.


Now on to the other side.

Had a rest from the 7 to split some wood today.

This pile took 8 hours to make - about 30 tons or so, or about 4 largish Eucalypts.

Splitter is home made from second hand parts plus new US hydraulic vales, hoses etc. loader is Aussie[attachment=34585]image.jpg[/attachment][attachment=34586]image.jpg[/attachment] built in Victoria, but they don't build them anymore as most tractors come in with loaders already fitted.

Had one problem when the loader bracket failed and the loader came thru the cab. New glass was 400 bucks😞

The 7 will take over most of the dragging work, especially as we move in to log a steepish gulley where the tractor can't go😊

Dang pics gone sideways ....

a question for the inter web experts
the pic is on its side here if click on the pic to make it bigger it's still on its side now if I double click on that pic it opens again but no longer on its side why is this so ?????

I think the only loaders made out here now are Kerfab at Kerang but maybe others still

No need for fire wood up here it never gets cold took me a while to get used to when I first came here splitter looks the part and sure would make the job a lot quicker and easier

Question:
Can the recoil spring be compressed by pumping up the hydraulic/grease piston?

I have the frame out so cannot use the usual method of placing a block in the tracks etc. to compress the spring.

I need to work on the front spring retainers on the frame one at a time, which are worn and currently welded in place.

Plan is to push the spring back with the adjuster and for safety, pack out the retaining bolt with spacers behind the nut - leaving the nut alone cause the threads are burred, remove the front locators, repair and replace.

Alternatively, I could leave it alone😊

Nice looking splitter and a good days worth of work splitting it. That pile would last me almost a month in the winter.
