Tree Farmer C7E Query
« on: September 15, 2021, 09:43:19 PM »
Hello, I've recently purchased a 1980s Tree Farmer C7E and I wanted to change out all the fluids and filters. Would anyone know what kind of engine/tranny oil this machine would take? I'm up in Northern Ontario where the winter drops around -30'C in January and the summer peaks around +30'C in July.
The machine has a Cummins engine, Clark Winch, and a Clark 3 speed powershift.

Any information about this machine would be appreciated.
Bobby

Welcome to the forum.
Working it full time in the woods or just for your own use?
Like the place to hook a chain in the middle of the blade.
Looks like a delimber on the side of the blade.

Thanks. It's for my own personal use on my property.
I believe it's good practice to change most fluids when purchasing old iron. 
I presume it's an accumulator on the blade. I've never seen one before, not sure what its specific purpose is.

It turns out I have a Cummins 6BT, Clark 3 Speed Power Shift, and a Clark Winch.

Should I run 5W-40 in the Cummins, to accommodate summer and winter?
What oil does Clark PowerShift use?
Should I run AW-32 or AW-68 hydraulic oil?

Thanks in advance,
Bobby

I would run a good quality 5w-40 synthetic, I like Rotella in the blue bottle. That's what I run in my Cummins B series engines. I can't tell you what for the tranny etc. That's a sharp skidder, looks like it was well taken care of.

Ok, one more. I'd say a aw46 hydraulic in the summer, and an aw32 in the winter. If you don't want to be changing it seasonally (I wouldn't) there are premium hydraulic oils that stay thin in the winter. I run Ponsse equipment, we had been running a Petro-Canada/Petro-Choice iirc and then Ponsse started getting a Ponsse label on it so I can't remember for sure what it was. I believe it is an aw46 with a very wide operating temperature range. We used to dump our hydraulic oil in the fall and switch out to an aw32, we don't have to with this oil. It's really more of a "performance" oil than you need, but if it saves you from the seasonal switch then it would be worth it. I think we pay around $20/gal US for it.

The grapple on the blade is to pick up the tree that came un hocked on your last trip or to per bunch

Awesome, thanks again.

Would anyone know what kind of oil goes into the wheel hubs?
