Trying to understand what is the best thing to do for hydraulic and hydrostat filters on my two New Holland Shibaura compacts, a 1520 with 3700 hours bought new in 1995, and a T1520 bought used with 400 hours in 2023, currently at 600 hours. I use Wix for the other filters on the tractors and all filters on my other vehicles, but I have stuck with NH oe for hydraulic filters because there hasn’t really been a big cost reason for me to not.
Considering that my two tractors are basically the same, (except for the T1520’s +10hp & nearly double the fuel consumption) they have different hydraulic filters specified by NH, with the T1520’s filter (84475483) costing nearly double that of the 1520 (9846407). The only clue I come up with is that the 2 filters each cross to a different Wix number with the T1520’s pricier filter crossing to a Wix filter with ‘enhanced cellulose’ and the other to a ‘wire mesh’ filter. The two Wix filters do have the same flow rate spec. My thought has always been that wire mesh was fine, maybe even better because of less possible flow restriction, for most any of the hydraulics found on a tractor except the hydrostat, and that is why the hydrostat has its own filter (more on that below). And to confuse things further, for the manual gear transmission versions of both of these models, the lower cost 9846407 is specified by NH, so only the T1520 HST upgrades to the pricey filter, not the 1520 HST. I can see no indication that there is anything significantly different about the KYB HST units.
The pricier enhanced cellulose filter is also 1-1/2” longer so it hangs down further to catch sharp obstructions. Is there a good reason to use the pricier filter in one tractor? And if so, why not on the other?
Then there is the hydrostat filter, NH recently superseded from 47671640 to SBA340501030 for both the 1520 and the T1520. Also, for about double the price. I have found no clue what may be different, both numbers cross to the same Wix number. Also, when I walked up to the parts counter recently and asked for a filter, they handed me the old number. I don’t know if they think it’s a better buy, or if they are clearing old stock, but New Holland does still list the old number as current, just not for this application.
It’s about time to buy another set of filters and I do not know what to get. Is Wire or Enhance Cellulose better when you also have a HST filter? Has anyone cut any of these filters open to see exactly what they are made of?
To supplement the above, I do not know if it affects NH’s filter requirements, but I am not a fan of their current zinc free hydraulic oil. I have their Premium Hydraulic Oil -Zinc Free Technology in my T1520 and will not use it again. I find its odor nauseating. And to me, zinc free is not something that I am looking for with my experience with motor oils in my flat tappet car engines. I most recently had NH’s previous best, Mastertran Ultratraction, in my 1520 and I thought it made it jerky. Prior to that I used 134 or UDT, whatever my dealer had in stock and wanted to sell me (I could not tell the difference and they used to sell whatever was less cost at the time, now only Kubota). Now I have SUDT in the 1520 and works fine, much smoother than the NH Mastertran
Sorry for the long post
