Calm down there, or you`ll blow a seal yourself!
Check whether you have reattached the hyd hoses to the correct ends of the ram, in case you have accidently reversed them? If this is the case you will have a situation where one ram is fighting the other/s.
I`m not familiar with that particular ram setup, but generally you would remount the ram on the machine, leaving the hose off til you have finished the remount. That way you can drag the ram shaft in or out by hand to make it easier to fit. Then fix the hoses back on, making sure that you have them the right way around. Once you have done the above, operate the "fore aft" fully forward and fully back a couple of times to get the rams back in sync.

its pretty hard to get the hoses wrong if you have ever seen this set-up.it is impossible to bleed at the ram, the front hose. with the ram extended that would be the one that needs bleeding, I would think, this is just an engineering nightmare as far as a reel ram. the one on the left side is completely out in the open.I can't figure out why the right one has to be hidden.I still don't know how to remedy this.You can't mount this ram first and the hoses last, that is part of the nightmare

They are rephaseing cylinders. You will need to hold it in full extend for a while to bleed/ fill it with oil. What did you fix on it? Seal kit, new cylinder?
sealkit.when I hold it full extend, the right ram is all the way back and it torques on the extended ram, don't I have to worry about bending the ram?I tried holding it for a couple minutes and nothing, how long do I have to hold it?
well it turns out the tech screwed up putting in the seal kit in the ram, dicked around all day looking for the problem, decided to take the ram back, another tech took it apart and noticed a part was in wrong, bring it back, voila, worked right away. ready to go now, suppose to rain tonight though, thanks for the advice fellas.

Hmmm, the name of this thread isn't very appropriate anymore......
yes it still is, taking off a ram shouldn't take 30-45minutes.Hmmm, the name of this thread isn't very appropriate anymore......

Exactly Only reason anybody doesn't buy MacDon is the premium they demand for them but it's worth it in the long run.

I like my macdons. 5 years now on a fd 70, original knife and guards. And it's seen over 20,000 acres. And half of that has been in the rocks and dirt. New fd 75 this year, I like what they did on design changes, except the end shields! Was told that was too satisfy the European rules?
It doesn't take many green stemmed wet lentils too see the advantage of macdon. Very versatile header that works in almost every crop and in a wide range of conditions.

Most harvesters switched back to deere heads because deere starting counting MUD discounts on dollar figures instead of number of units. 100,000 heads can really bring your discount percentage up pretty quick.
Also when financing thru Deere they add 1% when financing a different color, so almost makes you run deere heads.
We have deere 635f, 635d and macdon FD 70's. I like the simplicity of our deere heads, very little down time but our macdons will cut circles around them in tough conditions.
Today in lentils we had 2 machines with brand new 635f going 1.5 to 2.5 mph and backing up a lot. 4 machines in that same field with 2 year old FD 70's going 4 mph all day with 0 hesitations.
