  • maintenance
  • i have 52 8N that the lift arms drop as fast as they go up. i haven't looked inside yet to see whats going on in there. not that i would know even when i do. in very easy to understand terms and maybe pictures what do i look for.

    i also have a 53 NAA that does the same thing. could use the same help there as well. this one also needs a new hub and axle seals on the right side. i have looked on Just8N's and there all kinds of seals and rings, i would like to have everything i need to get the work done and not find out oh crap i need that piece once its apart. where can i get an exploded view of whats inside the axle to be sure i get what i need. i also have to change the hydro fluid on this one, all kinds of water in it.

    and they both need oil changes.

  • At the top of the forum page, click on "How To's" in the red bar.

    Scroll down to the section on HYDRAULICS, where you will find several articles relating to the hydraulics of your 8N and NAA.

    JMOR's excellent diagram is there as well as some info from Zane Sherman & Tim Daley.

    Reading the text, while relating to the drawings, should help you find the info you need to make repairs.

  • JMOR has an excellent graphic. You can also try John Smith's website under his Maintenance/Repairs tab. Very detailed axle seals replacement with pictures.
    Have no fear.

  • There are a number of leak points, but the most common is ram/cylinder piston ring(s). So start by removing the round cover near your right heel & with it lifting an implement, look up with mirror & light to observe oil coming out mouth of ram cylinder (where rod & piston are marked in picture).
