A Rookie with a New Model B

Hey Guys,

I just picked up a '47 Model B and a Woods finish mower to cut grass around the house.

A couple of "softball" questions.

1) What current Manufacturer's/part numbers of oil filters are available for this tractor?

2) What current spark plugs are being used in this tractor?

3) Can I use a synthetic oil safely in this engine? What viscosity (North Texas location)?

4) This tractor has a 3 point hitch assembly. What hydraulic oil is correct for it's use?

5) Is there an online shop manual available to look at or do I just need to order one?

Thanks for your help.

Go to caseih.com. they have parts and diagrams. if you want to buy parts you can get them here or your local IH dealership

For oil filters there is many to chose from. You can either have a tall or short filter.
Here is the tall filter part# you can use.
Wix 51125
Napa 1125
Fleetguard LF584
Bladwin PT70
Case IH 376375R91

Here is the short filter part #
Wix 51172
Napa 1172
Fleetguard LF618
Bladwin PT71
Case IH 376374R91

For spark plugs I use Autolite part # 3116

For engine oil I would keep it simple use good 15W40 diesel like Rotella or something like that. You could also use 10w30. For hyd. oil I would use any universal trans. oil.

If the tractor has a 3 pt hitch and hydraulics its not a "B" or its a very modified B, yes you can use syn oil but a good brand of 30 wt oil will be fine, I run wall-mart Tech oil in mine.
Oil filter is a Fram C135, spark plugs AC87 or Champion 15A this site will have manuals available just click parts.
Good Luck with your new tractor, Ppost a picture of it. Does it have a narrow front or wide front axle?

What type of add on hydraulic system does your "B" have?

Before you start blindly taking people's advice, we really should make sure what tractor you REALLY have.

A B with hydraulics and a 3pt hitch would be VERY unusual. Not impossible, but unusual.

The B does not have hydraulics or any provisions for hydraulics. Hydraulics would look very "added on."

More likely you have a different model tractor, perhaps a C.

Can you post a picture?

Wal-mart brand tech oil is made by Exxon mobile. I pick it up all the time in Paulsboro, NJ and deliver it to various wal-mart distruibution centers. Its good stuff.

You want pics, you got "em.

Looks like a "B" to me. Supposed to be a "47, but the serial number plate is gone, so who knows. Guess someone could tell me from the engine castings.

Aftermarket 3 point is a well done "home brew". Good welding, but holes are torch cut. Picks the woods mower up like it wasn"t there.

Would someone verify that this tractor has a tall oil filter canister? I got a replacement C135 Fram cartridge, but dimensionally it doesn"t appear to be tall enough to fit tightly in a vertical position inside the outer container (looks like it is about 3/8" too short). I need to get a new brass washer as well. It"s leaking all over and making a mess.

It also appears that the 3 point is running off of a separate hydraulic system than the touch control that is used for cultivator set up(?)Where do you fill and drain this hydraulic add on???

I have got to get a shop manual for this ride.

Mr. Mulebag:

I pulled all four plugs; 1 Autolite, 3 Champions. None were the same part number. Kinda confusing, however, I understand that whoever was "plowing" with this tractor was probably just loading it with whatever plugs he/she had available in the used plug box they had in the tractor shed. Of course, this means that everything on the tractor is suspect until I can go through it in detail. I"m sure you folks here on the forum are going to be a great assistance to me in this adventure.


Is there anyway to log onto this site so when a guy goes to post he doesn"t have to enter in his handle and email each time he wants to post something? Maybe I have just overlooked the login box.

Here's a pic of the added on hydraulic control for the 3 point.
