Did the W4 & H have a dip stick on the engine? I'm still amazed at the lack of one on this tractor. Can you tell me about the braking system? Thanks
1: No dipstick .. On yours you will find two thumb knobs on the R-side of the oil pan .. You crack the top petcock first.. If oil drips out you are good to go
If no oil drips out the top petcock, you close it and then crack open the lower one . If it drips, your level is within the safe operating range.. That's how it works. Been running these motors since the 1960's .. If the petcocks are too tight, just tap gently with a wrench or a light hammer.. Be gentle
If there is no drip from the bottom petcock (nor the top), you need to add oil.. Re-open the top petcock and fill only until the top one drips .. If you want to keep it continuously topped off daily you don't bother with the lower petcock, just add oil until it drips from the top one.. You get the picture
The oil fill is on the Right-front side , sits on top of the housing just ahead of the magneto (or distributor) .. It's a flat horizontal screw-on cap about 3" round.. The retaining stud is supposed to stay threaded down inside the housing but on some tractors the cap and the stud comes out as one.. Sometimes you may need to tap the finger ribs on the top of the cap with a wrench to loosen it.. Be careful, not too hard because I've seen tractors with a broken internal casting down inside the housing right where the threaded stud was supposed to attach
They are designed for straight-30W oil in above-freezing weather.. Also you might want to crack your oil drain plug for water at some point
Any manual on the Farmall H or W4 will cover your motor .. A manual on the W4 will likely cover everything about your "I" model and more, as you likely don't have a PTO or a belt pulley .. And of course none of the W4's, I4's and H's (nor any others except ford-ferguson) had 3-point hitch at the time, since ol' Harry's patent had not run out yet.. No power steering either.. The "I's" are usually a drawbar-only tractor
I owned an IH-McCormick Super WD6 (gas/diesel) for a spell, it was a tiresome tank to operate but very powerful on the corn chopper and baler .. It looked like yours but 2x the size all the way around .. There was also a shop mule made, which looks like your tractor but less than 1/2 the size .. Imagine that
2: Brakes. : Your brakes are inside the @12" round cast covers, one each appearing on each side of the transmission .. Yours will have the band-type brakes .. IMO they are a better brake than the disk-type that appeared post-1952 which is prone to grabbing and locking up tight when the activate/release balls get rusty or pitted
If your tractor has sat a long time you will want to take those covers off and lube all pivot points internally and externally before trying to use the brakes, or they may stick and drag .. Also it's good to use RTV or make a gasket for those covers when you reinstall them .. Rain water can get into them otherwise, and sometimes get into the transmission.. But perhaps the I4's have an ample platform above, protecting the brake housings from rain .. I know the H's and M's etc do not have that "luxury"
Which brings up another sticky point ,,,
You might not have a brake sticking. Instead, one side of your final drive may be seized by rust.. Crack the 3/4" drain plug located just above the drawbar and just below the rear PTO (or blank PTO cover). I bet water comes pouring out.. I bought a '53 once which drained a good 7+ gallons of water from the rear differential/transmission before I got oil
All these IH's from 1939 into the 1950's are famous for it .. Sometimes it's accumulated condensation, but mostly it's because the rubber ring underneath the metal shifter rain cap rots away.. Water runs right down the shifter , past the failed "seal", and into the trans
If you're lucky you may be able to free the brake or differential up by rocking back and forth , I've had that work out okay.. But not always
