Need Help with my Select-O-Speed Transmission!

[RickB]

New Holland part # 309735 is the filter (with seal included) for your SOS transmission. It is readily available although your dealer may not stock it on his shelf. There is plenty of stock in the various NH parts depots. Call ahead and pick up the oil and filter on the same trip.

The obsolete filter is the one for the older 4 cylinder prior model SOS transmission.

sd455dan - Thanks for the helpful pics. Got it sorted out yesterday. It was hard to find the timing port with the lower bracket for the dozer blade in the way. Couldn't see the marks at first, turned out the PO had the distributor one tooth off. I knew it was running too far advanced.

Though I feel pretty stupid not realizing at first that the battery tray swivels out to reveal the spark plugs. My tray was rusted stuck and it took some doing to get it unstuck. Needless to say the plugs were ancient Champions with not a lot of electrode left. But they were all good color with no oil residue.

RickB - Thank you, thank you, thank you! I'll be on the phone this morning tracking down two NH #309735 trans filters and 5 gallons of NH 134D oil.

For the hydraulics/differential the manual says SAE 80 EP (M2C53-A), I tried looking it up and it cross-references to a whole bunch of "universal" tractor fluids. I'm guessing the differential is more forgiving than the SOS tranny, but are there any fluids ya'll recommend? Perhaps a New Holland diff/hydro oil part number?

I really appreciate all the help fellas. This forum is the best! :drink:

good catch.. as you can tell I'm stuck on them 4 cyl prior models.

Good catch indeed. :thumbsup: I was losing sleep last night with my head full of visions cutting up filters trying to adapt one to work. :laughing:

I'm glad rick brought that up. I know we ( 4 cyl crowd ), are waiting for a SOS filter to come out. A member on another board is purportedly working with a manufacturer on a filter design.. but no production as of yet.

That's where i play mostly.. the 55-64 machines. have some of the 39-53 machines in the barn, but have lost interest in them over the years in favor of the red tiger models. I also have a few of the newer blue 65+ models in the barn, but havn't nearly played with them as much as the 39-64 guys.

My "dream" tractor is a 1964 Ford 4000 4 cylinder with Select-O-Speed, power steering, 540/1000 PTO, and two sets of dual remotes. It would have a hood & grill from an earlier 801 PowerMaster on it 'cuz I love the styling. I'd have a 703 front loader, 3-point backhoe attachment, and a vast array of implements to go with it of course.

If I come across any NOS trans filters for the older SOS series I'll be sure to let you know.

Any advice on the correct hydraulic/differential fluid to put in my 3000? Like I said I tried looking up the SAE 80 EP (M2C53-A) recommended in the shop manual, but the search leads to a myriad of "universal" tractor fluids. Is there a specific NH fluid or...?

Current recommendations are to use 134 in the transmission, rear axle, and power steering of your 3000. One oil does it all (almost).

 

[Soundguy]

Speaking of one oil. was it in the UK that they do have a UTF that can be used in the engine? ( or is that engine oil that can be used in the other? )

Gotcha. Thanks again Rick, you've been a big help! :drink:

I dunno, but that would be one heckuva do-it-all oil. Maybe mix it with some vinegar in a salad too? :laughing:

Btw, may I ask what the story is behind your username? Reason being I used to be a sound engineer back in Seattle. Had a few PA systems installed in clubs and a mobile PA for outdoor concerts. Most folks called me the 'soundguy'...
