New Member -YM 1700 transmission dipstick length

[winston1]

ok just found the screen assembly from Hoye

while i have the fluid drained, what else can i check on for the 3 pt lifting/lowering issues?

I can't think of anything that you couldn't check with fresh fluid and strainer. All controls are above fluid level.

If you saved or have any of the old fluid left. I would run it through a strainer try to flush out as much debris as you can. Your be able to just clean the new filter which I would do after a few Hrs. of operating time. Save the fluid it may not be that bad.

hey guys, can somebody tell me the diameter of the dipstick rod ? I have to make my own as well but everybody only lists the length.
Appreciate it.

Rod size really wouldn't matter. 1/4" would work. Thread size is 33mm.

33mm must be the thread size of the cap itself. I am almost positive that the actual metal rod can not be more that 1/8" dia. I just realized that my tractor is front drive assist and there is dipstick in the front wheel housing as well.
Thanks winston1 anyway.

why would you think it could not be larger than 1/8"? Just curious.

Flat Hatch marking 3/4"x 13/64 Width.. The Rod section 3/16 Dia. Hard to get a exact Measurement with what I had on hand. 1/4" dia. Max rod shaft. YM2000 so I believe it should be the same

Thanks careyo63. I did measure with my caliper the rod diameter from the front diff and it reads .156" dia. Yes there is a knurl end that is pushed into the cap so it stays in place and flat end on the other end to read the oil level. I have found an old welding electrode that once the coating is off is a perfect match to .156" dia and will make a dipstick out of that.

I will post a pic when done.

Cheers

I wonder where the old rod is? Any chance it is lying down there there in the transmission sump? If so, you might get lucky and find it next time you service the cleanable sump filter. BTW, that cleanable filter is something that we should all take out and clean every decade or so...but few of us do.

The measurement of 0.156" is awfully close to being 4mm, so that's probably correct. I'd sure think about how to best affix the rod to the cap. Obviously knurling didn't work for the previous one. I like things easy and permanent, so if I was feeling lazy I'd probably drill right through the cap and take the rod all the way through & put a bulge on the end to hold it.

Just so you know, the main problem with oil in the common transmission/hydraulic sump is that it gets water in the oil. The water enters past the gear shift lever when the tractor is left out in the rain. Over years enough water builds up to make the oil milky and kinda stringy.... which then clogs the cleanable filter.

As for the front axle, the problem is that on some front axle castings Yanmar positioned the filler cap right over the axle shaft. You want the oil level to be roughly half way up the axle shaft, but that is hard to tell since the axle gets in the way of measuring with a rod.
Most of us end up measuring the oil level in the front axle either by draining and refilling with a known amount of oil.... or we look for the level through the fill hole it using a tiny flashlight and a bent piece of welding rod. It's not critical. You want enough motor oil or lightweight gear oil in the front axle so that it can circulate past the un-shielded bearings at the outer ends and get to the right and left right angle gearsets.
good luck,

I hear ya rScotty. I wondered the same thing where the rest of the DS is . When I changed the oil in the fall, I have takes out the screen which was surprisingly clean (PO did some maintenance lol). But did not find the rod, so it is totally possible that is still resting at the bottom of the case. :scratchchin:

Anyway, my tractor is always covered so hopefully I will not have an issue with the water getting in the case but thanks for the info - always appreciated.

Front axle is a bit of pain to fill for sure but I just followed the specs on the amount of gear oil :thumbsup:

Actually, I really like you idea of attaching my new metal rod stick right thru the cap to be safe. I would hate to create another way for water to get in the case thou so I will see what I can come up with. I might have more time on my hand that I would wish for soon but such is life.
