We cleaned the valve spools and replaced the pressure relief valve in the bottom of the case. When we took the check valve apart we did not find a steel ball or a glass ball (I heard sometimes it is glass) but a plastic ball. I don"t know if the previous owner did a quick fix or if Ford thought this is a good idea but the plastic ball is all scored and rough. We tried to clean it up. Back together it the 3 point will stay up if nothing is on it but the lightest load caused it to drift down. My questions: 1. Anyone know where I can get a replacement steel ball? 2. Anyone know the correct diameter for this ball? As always thanks for your formidable help. [Reply]   [No Email]

It doesn't list a part number, just PL "Procure Locally" and the description says "Ball, Steel, Except NAA, Start Year 1/1/1955", which to me means that it doesn't exsist on an NAA (Jubilee) at all, and only on the later hundred series.

Am I wrong? What is the function for part # 353075-S (page 5-2 Master Parts Catalog) or NH diagram #26? Thanks [Reply]  [No Email]

I've looked at cover and hydraulic lift parts and still can't find it. Bad thing is I just got new trifocals. Finally found it, #26, procure locally, 15/32" steel ball. Now, where to buy only one, not 100. The blind hog finally found the acorn! This post was edited by Michaels Dad at 16:57:14 08/07/12 3 times. [Reply]  [No Email]

You can start at the main new Holland Agriculture products North American web page CLICK HERE. Then point your muse at, but don't click on, "Parts & Service near the top of the page, and then click on "SEARCH FOR PARTS" from the menu that pops up. Once you're at the parts lookup page, type in NAA as your model number and click the search button. Then click on "NAA 4 CYL AG TRACTOR ALL PURPOSE (1/53-12/54)", which should be at the bottom of the list. Then click on "Hydraulic Systems" and then click on "05B01 HYDRAULIC LIFT CYLINDER, SHAFT & RELATED PARTS, 53/54". This post was edited by Sean in PA at 14:53:36 08/07/12 2 times. [Reply]  [No Email]

You should be able to get it at your New Holland dealer, or on line at messicks.com. [Reply]  [No Email]
