Thanks for the reply, Tractor Sales Guy, but is anything ever as simple as it should be?
Regarding an aftermarket oil filter to replace the one on my TC24DA:
New Holland and Messick's parts lookups list the New Holland OEM filter as 87415600, formerly SBA140517020. It's supposed to fit a lot of the smaller Boomers, according to the lookup. I can't find specs on either site, which in my experience is the norm with manufacturer-supplied information.
Messick's lookup for a crossover gives Fleetguard LF16011. But Fleetguard gives that filter's BPV setting as 28.6 psi, more than three times as high as the figures I get from other sources for that tractor.
Fleetguard lookup using the tractor model gives LF3795, which is almost an inch larger in diameter and lists a BPV setting as 22.04 psi (as if the manufacturing process was anywhere near that precise). On the specs page for that filter Fleetguard says it replaces New Holland 86546618, which New Holland's webparts lookup cannot find.
The Wix crossover lookup, more reliable in my experience, gives 51516 or the shorty version, 51056, for the tractor. That filter's BPV setting is 8-11 psi (that precision sounds more realistic to me), which is about what I get from a few other filter manufacturers' crossover searches.
Naturally Motorcraft doesn't give specs for the FL400S, which is back-referenced on some lookups as replaced by the same filter as the one on the TC24DA. (That's supposed to be a Purolator and I went there, but I have to stop now because my eyes are falling out. When did I quit making sense?)
This is the kind of infuriating crap I expect to run into when I'm looking for something like this from virtually any online source.
I guess I should have just ordered the NH filter from Messick's, which I shall now do. But it would be nice to know the specs ....
Thanks for putting up with this.
