Here's one that references a number of things including NPT, SAE, JIC and "O" ring thread sizes. Also hose diameters, flow capacities, recommended suction lines, and some simple hydraulic calculations.

This one explains very simply how an open and closed circuit works with and without power beyond. Most of our tractors have open circuits.

I found this company useful in my recent upgrade of the Top & Tilt for bushings for my side cylinders.

I also found this site useful in getting an idea of what torque values should be given bolt size and parent material.

I thought I'd post this free download for a converter for Metric to English etc.
For those who do not have one yet.

Here is a cool hydraulics site with calculators. It's in the UK so units are metric and you'll have to use Convert along side it.
www.hydraproducts.co.uk/Hydraulic-Calculator.htm

If you have units that aren't in convert here is a site with a nice list of conversion factors.

I've got an PDF of the US Army hydraulics manual. I don't know how to post it.

Just saw this cat 1 hydraulic top link advertised at the top of our forum. At 149.99 it's a good price. I checked out the rest of their site and prices, the only thing worth buying from them is the top link. Everything else is priced way more than surplus center.

SurplusCenter has hyd. toplinks but they also sell swivel eye cylinders that are less expensive. Is there any reason one like this would not make a good toplink?
swivel eye cylinder
Would need cat1-2 bushings. For mine I would probably go with the 2.5"x 10" version at $150.

Brad,
I have that exact cylinder in 2-1/2" x 8.
Wish now I would've gotten the 10" stroke like you want.
One thing about that cylinder is that the swivel eyes are pretty close to the body...(not the rod end of course). Anyway, mine wanted to "squeeze" into the top link connection at the tractor, forcing that mount apart (wider). this was when I lifted the 3pt real high. So I had to cut the end off and add a 1-1/2" extension to keep the body from hitting the top link connection. Keep that in mind with the 2-1/2 cylinder. I'm pretty sure the 2" cylinder does not have that problem, but you are better off with the 2-1/2" one for our size tractor.

I had CCM's top link and it was a 2" cylinder. I could see the rod flex at times. That one is now on Loretta's 284 and works great for her size implements. Remember the very first one I got the swivel popped off?
Rob-

Thanks Rob, that's great info. It sure is nice getting advice from someone who has done just about everything with/to my tractor model. I remember you actually caught that top link failure on video!

Bolt torque chart - not as concise as the one Larry posted but it includes some strength numbers as well. Check out the clamp load values.
