H oil dipstick conversion

David G · Oct 24, 2009

Is there a kit I can get to install a dipstick for the engine oil on the H?

Thanks in advance

Have a look at the post below. Mike CA has a pic posted of his oil pan with an aftermarket dipstick installed. The are available used.

I lucked out and find mine on a junk pan in a scrap yard. I bought it for a buck. I've seen them on Ebay go for $100+. I've kept my eye open for more, but this is the only one I've ever seen around here.

I see them on ebay from time to time, but hold on to your check book. Also, they are not accurate. I've got one that I removed from my M and replaced it with an original style petcock.

Rusty: How can those oil pan dipsticks not be accurate? We had one on Dads M and had no problems. I know on the M's just above the frame rail is a flat spot on the right side is a flat spot for a farmall 300/400 style dipstick. H's should be the same. The TD6 (M engine) had dipsticks at that location. If the petcocks were so good(Iknow the orignal reasons for them) why did they do away with them starting the hundred series and the track letter models(It was just about impossible to get to the petcocks on track machines) Armand

We're talking about two different things here. The dipstick you are talking about is factory installed on the 300s, 400s, etc, and it is accurate.

The dipstick I am talking about is an aftermarket thing that replaces the top petcock in the oil pan. You remove that top petcock, and replace it with the aftermarket doo-dad. You can see it in a picture in one of the posts by Mike ca.

With all due respect Rusty; how are those after market dipsticks that replace the petcocks not accurate? We had one on Dad's for 4or5 years until his sale in 1969 and had good luck with it. It was at least as accurate as those petcock as with the petcocks you never knew the exact level of the oil. I have also seen M's with after market dipsticks installed in M blocks same as the number model tractors. Please reread my earlier post. Armand

Like I mentioned before. I have one. It was installed in the pan of my 1940 Farmall M. The first thing I did after bringing that M home was to change the oil. After pouring in the appropriate amount of fresh oil, I checked that dipstick, and it indicated that I needed another half quart of oil. I then removed that aftermarket doo-dad, and the oil level was right there at the bottom of that petcock hole. In other words, the oil pan was full, but the dipstick indicated it was 1/2 quart low.

I have had several other folks relate the same experience with the aftermarket dipsticks.

The dipsticks like mike pictured are pretty close if the hole and threads in the oil pan are 90 degrees to the pan mounting rails. If tilted a little it moves the end of dipstick up or down enough to change reading. Easy for the holes to get off square when petcocks are tightend or removed with pipe wrenches and a good bit of pressure. If the oil level was at the bottom of petcock hole it would still have to be a little higher to go through the petcock.
