Some basic questions on my M

Well I got the manuals and have skimmed over them and can't find the answers to my questions in there but I think that is because they were written back before you had to put warning labels on coffee saying that it might be hot! ;-)

It looks like to take the hood off I need to take the air filter and muffler off. Does that sound right?

Also I'm still confused on how to check the level of the transmission fluid. The diagrams go into great detail about checking and changing the engine oil but seem pretty sparse on the transmission stuff. I don't remember seeing hardly anything on the hydraulic system. Is the transmission and hydraulic fluid the same?

Lastly there is a little flap on the left side of the transmission casing. I can move it and look into the transmission and see a bunch of gears and they look like they have really thick oil on them. I guess the oil is heavy enough and thick enough it isn't going to spill out through that hole because it isn't sealed very well?

I can take pics if needed.

Thanks very much for all the help so far.

Nathan

Hello Nathan,

Where at in Texas are you? We have a small farm near Waco. I am currently in Eastern New Mexico and am always looking to chat with folks in Texas.

later days mate,
Jim

I grew up driving an H Farmall, and until this collector bug bit me I didn't know there was supposed to be a dipstick for the hydraulic system. Our system for checking the amount of oil in the system was simple, if the loader would not go all the way up, you added oil to the reservoir until the loader WOULD go all the way up. Dipsticks are overrated.

The dipstick might not be there for checking the hydraulic fluid level is an understatement. In my experience with Hs and Ms, they are more often gone than present. I fashioned one out of some thin allthread and a fender washer ground down to fit on top of the pipe but inside the cap. Drain the belly pump (that plug at its very bottom) and add what your manual says is its capacity. Then use the level that shows up on your fabricated dipstick to file a notch and that'll be your full mark. If you ever take apart your hydraulic belly-pump, you may find the dipstick at the bottom of the reservoir. That's where I found mine.

Nathan - The flap you've shown circled on the flywheel housing is for lubing the clutch throwout bearing. If you swing the flap aside you'll find a zerk fitting recessed behind it. (The "gear" you see inside is the flywheel ring gear...)

As for removing the hood you indeed must remove the muffler. But the air cleaner can stay in place - simply knock the cap/screen off the top of the air inlet (a couple sharp upward whacks with a wood hammer handle and it should pop right off), then lift the hood over the tube. This is most easily accomplished with one person on each side of the hood!

Here is the right side. Where do I check the hydraulic oil? I know where to add hydraulic oil but not sure what level it should be at.

Thanks! Nathan

The non-factory return hose T under the fuel tank with the red crownlike ribbed knob on the top of it is the problem. The hydraulic system return line gos in the elbo with the plug in it farther down the side of the housing. The crown like cap should be removed and all those fittings as well. Here is how it fits together. With nothing on the nipple sticking up from the castiron (where you removed the erroneous "T") there needs to be a felt or leather washer, about 1" ID AND 1-3/4" OD placed over the pipe and against the housing (keeps dirt out)on top of this is a large thin flat washer which pushes the leather down toward the housing (1"ID ~1-7/8"OD. A coil spring also fits over the pipe, it is weak but effectively pushes the washers down. Next in the mix is the dipstick. It should be a loose dip stick poking through a flat washer with a small hole (I recall it being about 8in long)this is the level indicator, and must go into the standing nipple, and the washer rests on the top of the nipple. (It kind of goes inside the top of the un-compressed spring but is correct. Then the Crown knob gets screwed on firmly by hand. no pliers. The knob is screwed off and dipstick removed to check the oil. this is also the hole through which additional oil is added (with the dipstick out) I hope this wordy message helps, email me if not.

Okay, it is so much easier to look at pictures for me.

Here is the left side of the transmission. I circled the peek hole that I'm talking about in yellow and from my understanding the transmission oil level should be even with the bolt circled in green?

The picture isn't that great because I had to save it as a gif file in paint after drawing on it.

Here it is with the peek hole open. I guess this is where you would add the transmission oil?

No,

Transmission oil goes in here and up to the level of the rear check plug circled in green on your photo.

Nathan,
Regarding the hole you're talking about on the transmission (where you see the gears), if it's the on the left side of the tractor (facing front) and about a foot in front of the rear axle, that's the view port and level indicator; it's a 1/4" hole. When the transmission has the correct level of oil, the oil level should come to the bottom of that hole, or maybe just above it. The oil should be thick.

Here's what I do to drain water out of the transmission: I slowly "remove" the large plug at the rear bottom of the transmission case and let the water drain out - I keep the plug setting on the hole and rotate the bottom of the plug away from the hole until it makes a small crack for the water to seep out; I then screw it back in. There's also a small 1/4" plug at the front of the transmission, and I drain water from that as well. I've been blessed to not have water come out in the last couple of years.

You are correct on hood removal. I hate how some would just unlatch one side and bend the hood up to get to something. On the tranny look for the overfill plugs on the side. If you remove it and oil is coming out you most likely have water in the rear end. Drain that out now and agian if you leave it outside. The liftall belly pump take non detergent 30wt and should have a dipstick but not all the time.

Very good advice so far, and all right on the money, the one thing more I will mention is the filler for the transmission and rearend, which are all together, is the (approximately) 2 1/2 inch threaded plug with the 3/4 square drive hole in it located just behind the center post on the operators platform which supports the steering wheel. Kinda a bear to get a bucket to, so I use a long funnel. Pull that plug, and the small plug you have circled in green, and fill the large plug till it runs out the small plug. Like others have said, open the plug in the rearend, directly under the PTO, and drain all the water first, when the oil starts running without water in it, replace the plug, and fill to capacity, or ampicity, whichever comes first. Hope this helps. Later, Harley
