    52 8N "runs perfect"

    Someone in my vicinity is selling an 8N that “runs perfect”. If it truly runs perfectly I think it would be worth it. In all seriousness it at last appears to be very nice in the photographs and has a finish mower with it as well. Asking price is $3,350. See the listing here...

    Jubilee hydraulics again

    Was able to get a better look at things by looking through the fill port. “Stream” of fluid I mentioned is not coming out from back pressure valve o-ring, and wouldn’t anyway as you mentioned JMOR. Turns out fluid coming from out of pressure port on top of casting directly above pressure tube...

    Jubilee Hydraulic Relief Valve

    Well the standard o-ring was a bust. I didn’t realize this was the issue and made a separate post here: https://forums.yesterdaystractors.com/viewtopic.php?t=1389670 The o ring came from NEW HOLLAND and had the correct part number according to the sales rep. Guess I’ll need to keep looking?

    Jubilee hydraulics again

    That could be. Although after taking another look at things I have another wrinkle to throw in the equation. Previously before replacing the relief valve I also had a small stream of fluid coming from area where back pressure valve sleeve seats against lift cylinder housing. The o ring had a...

    Jubilee hydraulics again

    I can’t seem to get everything going well with my golden jubilee hydraulics. Fixed initial problems by adjusting linkages and replacing unloading valve o ring. Plowed a garden and everything Seemed to work fine except draft control wasn’t quite right. Then after some post holes it quit...

    Jubilee Hydraulic Relief Valve

    Sorry about he confusion - That was a separate issue. The gasket behind the back pressure valve appeared slightly damaged. Received a new one from New Holland today. It’s the same diameter and thickness but doesn’t have the same “ribbed” feature around the outside diameter and inside diameter of...

    Jubilee Hydraulic Relief Valve

    It is the relief valve at the bottom of the center housing where the pressure line comes in, part NAA638E. I have seen them online for $110 and $97 but currently checking with a local parts supplier who sometimes gives a little better pricing. Sure wish there was a way to just replace the...

    Jubilee Hydraulic Relief Valve

    I removed the relief valve and took it apart by removing the threaded piece from the top of the valve. There are two springs, one smaller diameter spring inside a larger diameter spring. These are pushed up my a small steel ball and washer by the hydraulic fluid. Higher pressure compresses the...

    Jubilee Hydraulic Relief Valve

    I obtained a mirror to look through the inspection port and it appeared I had fluid coming from the back pressure valve at the lift cylinder where the o-ring is. Had a somewhat difficult time sourcing the o ring but a nearby New Holland dealer was able to find one for $6. Relief valves are...

    Jubilee Hydraulic Relief Valve

    For the second time, my hydraulics lose ability to lift after drilling about 3 post holes with my auger. If I force the lift arms up by hand, the hydraulics will hold them there, but will still not lift further. When taking off right side inspection cover, I see quite a bit of air bubbles on...

    Jubilee Doesn't Like Post Hole Auger

    A few months ago I received a lot of help from this forum (see https://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=nboard&th=1035425) and was able to get my Golden Jubilee hydraulics in operating condition at least in implement control after removing the unloading valve, replacing it's...

    NAA - Hydraulics Unloader Valve

    Thanks Hobo! As I mentioned in the last post, I am going to replace the o-ring. I might be hardheaded, but not that much! :wink:

    NAA - Hydraulics Unloader Valve

    The o-ring did not break when I removed the unloader valve, and appears to be in excellent condition the best I can tell. I was thinking about just keeping the same one on there, but have decided to get a replacement just for good measure.

    NAA - Hydraulics Unloader Valve

    I probably didn't choose my words the best there when I said "drove it out". It came out quite easily, just by inserting a punch by hand from the back end after inserting it all the way. Removing the valve the first time took a little more force but after that it was very easy, just with a...

    Temp Gauge Fit

    I purchase a temperature gauge from a local parts supplier. It specifically lists NAA as one of the models plus some other more recent models. Appears to be the same as the one sold here on YT: https://www.yesterdaystractors.com/Ford-NAA_Temperature-Gauge-Black-Rim_C3NN18287ABLAC.html...
