Farmall H Dipstick

Wheet · Jan 18, 2011

I just bought an H that has a dipstick casted in the engine block. I have never heard or seen another one like it. Is this a rare?

There were add ons you just drilled a hole and installed the dip stick. They also had them that replaced the top petcock.

Could be a powerunit engine replaceing the original.

It is mind bogling that these tractors did not come from the factory with dipsticks. Every car and truck and some I, H. products at the time had oil dipsticks. Why not the tractors??? Armand

kind a like the F20s,no full pressure oil system...you had to oil the valvetrain with a squirt can!F1 2s,trucks,others had full pressure systems!..go figure.

On distillate tractors you could much more accrurately monitor the oil level with the pet cocks than with a dip stick. The distillate or kerosene would dilute the oil and raise the oil level. If the oil was over the top pet cock you let it run down untill it was at the proper level. With a dipstick you would have no way to do this. If no oil ran out of the top pet cock and oil did run out the lower petcock you had the proper amount in the engine. If none ran out the bottom petcock you added oil. Very good and efficient method.

The H engine with a dip stick is either a gasoline power unit engine or a gasoline replacement engine.

Are these add-on dipsticks still available?

The IH tractor engines all had locations for dipsticks, look at the sides of the farmall A, H and M engines just above the seam to the sump. The petcocks were more useful for kerosene/distillate, you drained the oil from the lower (A,H M which had only two petcocks or the middle one (10-20, F-12 etc. which had 3) to get rid of the kerosene diluted oil (about a pint), then filled with new oil till the level was back to the top petcock. With only a dipstick, you would have difficulty, the kerosene/distillate is on top so using the drain plug you take out the un-diluted oil. For gasoline(petrol) tractors the dip-stick would be just as easy. Someone had drilled the dipstick location on my W-4 to put a dip-stick in place. The petcocks are still there. The IHC diesel tractors always had dipstick, though usually a screw-down cap to keep dirt out.

Dipsticks were first installed factory in late 300 & all 350 series, same for 400 late & all 450, you could add them by drilling hole or maybe this had a replacement engine or crankcase put in at some time, remember these are 50+ years old.

I made my own many years ago from a piece of 3/8" copper or steel tubing with a flare being formed at the top end. I used a dipstick from an 8N Ford because it would easily fit in the round tubing. I adjusted the height of the top of the tube to line up the dipstick's full mark with the correct height of oil as determined by the oil pan pet cocks. I had no idea that a kit was available for this conversion, but wanted to be able to easily check the oil level every time I ran the tractor. The dipstick from the 8N has an inverted cup brazed near the top that will shed water away from the opening of the top of the tube. The 8N dipstick is not a flat stock piece, but rather a round stock with a flat side ground into it. So it fits well into a small tube.
