Is the oil filler cap on an H supposed to just be finger tight? Mine is really tight. I don't want to put a wrench with teeth on it because it will damage it. How should I pop it loose? How tight should I tighten it once back on?

Crescent wrench worked easy as pie. I just gave it a little pressure and it popped right open. I even bought my oil today, including MMM and engine flush at the end when I'm ready to really clean it out! Filter is already in place. Now I just need to fix the rust hole in my " new" oil pan, put a gasket on it, and it will be ready for oil!

the cap should be put on finger tight when put on. what will happen thou is that because the cap is in a verticle position with right hand threads that when the tractor get hot the metal expands the engine block first then the cap as it is more exposed to air and the vibration of running it will actually have the cap go down a couple of thousands more and seat itself. that is why a slight tap or a wrench is needed to take off the cap.

I'm with randy. They need to be "snug" you dont want them vibrating off. The H toolbox was NEVER without a cresant wrench. We NEVER hit them though. I do remember an ear broken off of one once. If you wanted to check the oil, you went to the tool box first for the cresent wrench.

PS. in the old days they were all American made cresent wrenchs. I have on that is made by the Diamond Caulk Horseshoe Company. pretty neat. I took it out of service for fear of loosing it.

i don't understand all the fuss over this. i've been opening and closing them with a cresent wrench for over thirty five years.

I agree, if not painted, I just tap them with the wrench. I don't trust hand tightend threads on something with a lot of vibration.

Mike, you've recieved several replies below, most all of 'em suggesting either a crescent wrench or a hammer. Either will work... I've always just used whatever's handy to whack 'em with(ok, a "light tap")....but it reminded me of an old joke.... A farmer asked his hired man to run into the shop and bring him out a crescent wrench. The hired man asked "do ya want a 10 inch crescent or a 12 incher?" The farmer replied "don't make much difference to me, I'm agonna use it as a hammer anyway"....

I always use just fingers putting it on, almost always have to use a tool to get it loose.
Good luck, Wm

Sometimes those caps are tight, you can tighten it with your fingers. Use a crescent wrench to get the cap off, it should not be very tight.

Mike - The filler cap should be tightened only finger tight.

If it cannot be loosened by hand, a properly adjusted crescent wrench slipped onto one of the cap "ears" will give leverage to break it loose without damaging the cap.

The cap (with the two wings on it for your fingers) is supposed to be hand tight. It often got tighter from temp change, and required an adjustable wrench to loosen it. We were casual, and just put the wrench on one of the "wings" If I were you, I would use two wrenches, one on each wing. It should come loose easily. Do not hit it with a hammer. If it still refuses, use a brass punch to shock it at the base of the wing, where it flattens out into the cap. Lefty Loosy. JimN

give it a shot of penetrating oil on the center of the cap, thats where the stud comes thru. then use either a brass head or lead head hammer and gently tap the wings counterclockwise to unscrew it. if ou have a big crescent wrench you and close the jaws so they are about snug on the wings and try that too, be gentle dont try and kill it!!!

Put a wrench on it or hit it with a hammer. The cap is supposed to be tight enough to not come loose while in operation. Righty-tighty, lefty-loosey.
