8N hydraulics question

Last Wed, I put a new NAA piston & cylinder in my 8N, and replaced some worn pins. Before, you could just about watch the arms go down if you stopped the PTO. Now it stays up FOREVER! Just wanted to brag a little before asking my question.

The NH man said I would probably have to take the upper hyd in to them to align with their special jig. I remembered talk about such things on this board, but thought I'd try just going by the manual first. After re-adjusting and re-installing the hydraulics, the arms seem to go through the full range, and get to the top when the control is at the top. However, there does not seem to be very much control on the lower half of the touch control lever.

I was wondering... since the pin that rides on the cam was worn about in half, wouldn't the cam also be worn, and couldn't the lower half be worn to the point that the full range of the touch control lever may never be realized? Am I missing something? What should I do?

Usually the cam does not wear enough to cause any problems.

problem probably is that the draft and the position controls are not adjusted properly. It does need a jig in order to have a reference point to go to in order that the right adjustment is achieved the first time. This may be what they were refering to at the dealership.

See the link below for more information on the jig that I make along with an illustrated booklet.

Replace the pin..... It's softer than the cam. Zane has posted several very excellent instructions. Check the "archives" at the top of this most excellent N-Board for more info. ..... ..Dell
