NAA 3-point won't go fully up

I own a '54 NAA. The 3-pt lift won't go fully up. The cam follower pin was replaced a few years back, but that didn't solve the problem. I think, but can't be sure, the linkage may be out of whack. I have the I&T F0-19 Shop Manual that shows the procedure, somewhat, for the lift linkage adjustment. They state the proper feeler gauge thickness to use for setting both the draft and position control linkage. I see Zane sells a booklet on how to do the NAA linkage adjustment. He also includes the cam follower pin and a gauge tool. Has anyone used the booklet and tool Zane sells? I'm wondering if it would be a good idea for me to get this, even though the I&T manual I have shows, somewhat, how to adjust the linkage? Perhaps Zane's booklet has a couple slick tricks he's learned, or is more thorough in explaining the linkage adjustment procedure? If Zane's booklet & tool are a good addition to the I & T manual, or perhaps even a better way to go, I'd be happy to send for it, but if it's not really going to do anything additional in helping me fix my hydraulics, I'd rather put the money in needed parts. Is it a good idea for me to get Zane's booklet and tool even though I already own the I & T Shop Manual? God Bless,
Poppy.

Thank you all for your replies. And thank you Dan! That instructional looks to be EXACTLY the information I'm looking for, with plenty of clear photos. I LIKE IT! I enjoy his sense of humor throughout, and you can't beat the price (sorry, Zane).

I already have the video Ramrod recommends, so I'll be viewing that again & printing out his excellent tutorial and give the project a go sometime this summer.

Thank you again.
God Bless,
Poppy.

Zanes booklet is very good and has helped many and has many rave reviews - I don't think you could go wrong there. However; send me an email at hercheal at yahoo dot com (note the spelling) and I will fix you up with a step by step manual with plenty of pictures and tips to get your NAA hydraulic lift cover adjusted perfectly - free of charge.

Sorry - I forgot it was already on the web. Click below for Ramrod's excellent NAA hydraulic adjustment document and tips.

Dan that is one of the best adjusting instruction for the NAA I have ever seen. Except for mine of course!:O) I did note that the gauges used are a bit off but not much and using the key stock is a good idea. The exact measurements are .155 for draft and .240 for position but that key stock is probably close enough for government work.

I also thought that my idea to use the flat washer to shim up the worn draft plunger and anchor plate was mine exclusively. Actually I realized that could be done to shim up a badly worn draft linkage back in 1962 or so. I guess if I could figure it out so could somebody else????

I still have my kits for sale and sell one every now and then but this guys stuff is good I have to admit.

The reason that gasket you show is no longer available is because it serves no usefull purpose. There is no place for pressureized oil to leak where it was used. Maybe one of the engineers designed gaskets and had to have a showing for his pay that week????

Good show!

Yep - I worked with Ramrod when he was putting this together (he is very @nal that way) as I was rebuilding Rustbucket at the same time he was rebuilding his own Old Warrior. I am the kind of guy who has to do things three and four times before I get it right, whereas Keith analyzes everything for the best way to do it first. The square stock is not perfect, but I can vouch that it is indeed good enough. Here is a pic of Rustbucket after I finished mowing and raised the heavy old shredder clean off the ground to measure leak down. After a few hours it was still up, so I decided to go to bed. The next morning it had dropped about 3", but the rear wheel was still off the ground.

This was with the engine off and nothing touched for over 15 hours. Good enough for Government work indeed.

You are still the master at N Series hydraulics, a glowing review from you means plenty.

Very impressive! Hope you have many years of use out of the old girl.

Thanks for the kind words. I still don't understand how he came up with the idea of using that flat washer to shim the draft linkage if that is his first one to do. Smarter man than me!??? I scratched my head on how to get a worn out draft mechanism to work for years before I came up with that idea. Either the FO or the It manual or both of them tells you to lengthen that internal linkage by using the retaining nut to adjust the draft linkage. That absolutely will not work unless there is enough room still left on the threads to add a jam nut. Otherwise it will eventually fall off and when it does the draft will cease to work.

I will say he thought about filling the worn area with weld first - but figured it was too labor intensive. That is when he showed me this alternative.

A friend made me a tool with the proper gap 0.432
in.as indicated in manual.[note in FO-19 all other gauges are obsolete]and set my own,works fine.[bear in mind when setting linkage all parts are worn to some extent and it is difficult to achieve all of the precise measurements]
