I don't know all the details. I stopped by one day (40 miles away), and had about 5 minutes to look at it, and I was in my "good" clothes.
My uncle bought an 8n with a loader. He got it home, and replaced a couple hoses, one at a time he said (he's not a farmer/rancher, lives in the village). He raised the loader, and that's it, won't go down. I looked it over when I was there, I don't see anything obvious externally. The hoses go to Ts/couplers to split between the two cylinders. Unless I'm missing something simple, it looks plumbed right. Bucket works correctly, two way cylinder, arms, one way. Best of my recollection is the attached rough drawing. I've not... had this issue myself.
Is there possibly a back/down pressure adjustment that's off? Maybe under the cap? Otherwise I was thinking a blockage, or somehow the cylinders are binding up?
I suggested propping up the bucket/arms carefully and loosening the pressured hose to see if it was at the valve. I had all my weight on the bucket, it did not budge in the slightest. Moving the control, you can see the hose when it's getting a bit more pressure, but it doesn't seem to lose that much when the lever is moved the other way, but it does seem to lose some, hose is very stiff so it's hard to tell without loosening it....
He's not getting to it, and has mentioned having someone work on it. I really don't have time to head back over there to work on it during haying. Just wondering if I missed something obvious, or other suggestions. Thanks.

Today's Featured Article - Upgrading an Oliver Super 55 Electrical System - by Dennis Hawkins. My old Oliver Super 55 has been just sitting and rusting for several years now. I really hate to see a good tractor being treated that way, but not being able to start it without a 30 minute point filing ritual every time contributed to its demise. If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
