Three point lift chain set

Kenster · Nov 27, 2017

What is the chain set called that you use to support implements when your hydraulics are weak?
I’ve had a set for years but several links are now broken and I need to replace the set. Repair links don’t hold.

I can’t find a set on line, probably because I don’t remember what they’re called.

Thanks!

Limit chains. Not sure if this site sells them. Google them and you will find several supplier.

Limit (limiter) chains! Yes, that’s it.

Thanks!

The ZANE Thang - if you have a 9N or a 2N you do not have POSITION CONTROL (8N and after does)only draft control. Weak hydraulics make it even tougher to maintain constant height. Zane Sherman, long time member here makes and sells a device (The Zane Thang)for 9N and 2N tractors that adds Position Control to their hydraulics, just ask. As the ol' Cook said, LIMITER CHAINS are sold at just about every tractor parts supplier. We can only assume you have a 9N or 2N by your question...

Nope. 52 8n. The shredder I use is a VERY HEAVY JD and my hydraulics are quite up to holding the shredder up. The limiter chains have worked well for years but the weight of the shredder has broken a few links and the repair links.

I have access to a neighbors lighter weight shredder now but still need to replace the limiter chains.

That should read that the hydraulics are NOT quite up to...

Edit function not working.

Like I said, the 8N has POSITION CONTROL so really don't need limiter chains. How heavy is this shredder? Do you mean a brush hog? Have you tried your position control setting? Are your hydraulics that bad? Have you done the basic system test? Raise the lift with a load/implement, shut down tractor with it UP. How long before the load drifts down? A good hydraulic system will sustain a load in the UP position for weeks, months even. If the load drops within minutes or hours, you have a severely worn out cylinder and it may be time to pull and rebuild the pump. With lift up under load, remove inspection covers and look up under the top cover where the cylinder is bolted to. Use a Mini-Mag or other decent light and look close and good for any signs of oil oozing out of the cylinder. If so, the cylinder is worn and needs replacing. The original 9N, 2N, and 8N cylinders used a piston with three steel rings, similar to your engine pistons. This was the method of 'sealing' the system. Over time, these steel rings would wear grooves in the cylinder walls and thus start leaking. The good news is that when the NAA was released in September, 1952, the entire hydraulic lift system was redesigned by Ford, partly due to the ongoing Ferguson lawsuit, but they had been working on a better design long before he filed suit anyway. The new cylinder used a new piston which utilized a rubber O-RING with a leather back-up washer/wiper. This piston will also work in the 9N, 2N, and 8N system/cylinder as well. If you want to contact me I can direct you to a How-To article on repairing your 8N hydraulics on a budget....

Thanks, Tim. I’ve had this tractor almost 12 years so I’m very familiar with the systems, including Position Control. I know all about leak down. I’ve been reading this forum since the day I got the tractor.
My hydraulics are weak. It won’t hold the shredder (bushhog) up
very long. That’s why I use the chains. That’s what the chains were designed for.

However, my buddy down the road also has an 8n with weak hydraulics. AND he has the skills to rebuild it, which I don’t.
So, this winter, we are going to pull the systems off both tractors and set them side-by-side on the bench in his shop and rebuild them both. The compete kit and new pistons. Hopefully, that’ll do the job.

I appreciate your input and I’m sure to have questions when we get going.

I have an 8N that works fine since I just replaced the cylinder piston and the dowel pin. But I've always used limiter chains for my Woods M5 mower. I prefer to have it just hanging there on the chains to having the position control work to keep it there.

I appreciate your input and I’m sure to have questions when we get going.

Here is a link to a good DVD on repairing the "N" tractor hydraulics.

This sounds familiar. A few months ago there was a post with two guys going to do exactly that -pull their hydraulics and rebuild them together -must be you again. As I said then and will say it again, get the manuals and know what you're going to do before you do it. Chances are you will need a new cylinder, yep, don't just replace the piston, a new piston (get the NAA style), and gasket kit, but, I would wait until the systems are evaluated to determine what exactly will be needed. If one or both pumps are cracked, then replacing will be required. New, used, and rebuilt used pumps are available. Since you will be pulling the top cover and going thru the entire system thoroughly, I'd do it right the first time so you won't have to pull it off for another 20 years or so. I would bet the farm that your cylinder is badly worn and it has the original 3-ring piston in it.

I a have a set on my 8n mower, would not go back to mowing without them. Much easier on an old hyd system.
