Need photo of 1010c transmission drain plug location

[newwood]

Embarrassing problem. Went to replace the transmission fluid on my 1010c diesel with reverser and despite staring long and hard at both owners and shop manual for drain plug location I cannot for the life of me find it where it is shown in the manuals. I can find the reverser drain plug no problem. But the transmission drain plug is totally eluding me. It should be accessible from the left side, from manual looks like it is rearward of the reverser drain plug but I can’t find it. Can anyone send a photo?

LH side of the transmission, basically below your left foot as you sit on the crawler. 3/4" NPT plug.

Lavoy. Is it centered over the top of the rear cross bar on the left side? I already made the mistake or removing one of the “cap screws” on the reverser thinking that was it (but no fluid came out—oops— so I’m trying to avoid removing more wrong bolts).

[Lavoy]

Don't remember for sure, but it is not a bolt, never will be, so don't take any more bolts. It is a 3/4" NPT pipe plug, lower side of the trans facing to the left just ahead of the LH steering clutch housing.
Look in your service manual, should be a pic there.

Lavoy— well, I’ve stared long and hard at the photo in the owner’s manual (and the shop manual—which unfortunately has only the very same photo) and I’m not finding any plug on the side in that area. I’ll see if I can send a photo of the area I’m out of the woods and back home. There are a couple plugs facing down (not to the side) accessible from the rear near the drawbar, but those plugs are definitely not what’s shown in the owners manual (and those particular plugs never appear in the owners manual—very mysterious).

I have a 1010 so I went and took a look and see the drain plug just where Lavoy described.
When I got home I took a look in the pars manual and it shows 2 drain plugs.
One on the left and after serial# 48383 the case was changed and the plug is on the right side. So if your serial # is higher than 48383 or the case was replaced the plug will be on the right side.

Hadn't thought of the serial number change, good call.

So I’m out of the woods (just time, the mosquitoes were about ready to carry me off). The manual shows this [https://share.icloud.com/photos/0f6S7Tq ... uGNzflJi_g]
But because of my blade I see this when looking from a similar vantage point

Which if I go inside the blade mount looks like this

I removed what just turned out to be a bolt in the upper right. The there is a plug in the upper left (recessed hex) but that’s probably not it because that’s even more forward. So what I now think is that it’s the cleaned off hex bolt/plug in the upper right of this photo
[https://share.icloud.com/photos/0ceo13q ... lyUFpzheAA]

Although if a NPT plug has a square end or a recessed hex end it’s easy to recocognize as a “plug”, if it has an external hex (as shown in the owners manual photo) I don’t see how a guy can tell from simple external characteristics the difference between a “bolt” and an NPT “plug” (which is a thread characteristic that’s not apparent until it’s removed?)

This is a pre-31000 model so should be on the left (and indeed none of the bolts/plugs shown in the photos are on the right side)

So is the 4th photo upper right the bad boy I’m looking for?

Here’s a better photo of the one that I now know is the wrong one [https://share.icloud.com/photos/07d61Oi ... 5sp8R45iqQ].

The exploded parts diagram is perhaps even more confusing and appears to show it on the right side (it’s definitely not)

As I said:embarrassing that I can’t figure out. Thanks to all for any guidance.

Bolt has strength markings on the head, hex plug will not, plus they look quite different. Bolt likely has a lock washer under it, hex plug will usually have exposed threads showing. It is not likely a hex head plug. Original is standard square pipe plug, not that it couldn't have been replaced.

Well there’s nothing with a square end, recessed socket, or exposed threads showing. But here a closeup of my best candidate

There’s no strength markings and it does not have a lock washer and although it doesn’t look to me to be “quite different” except for a more machined appearance, perhaps you can identify this as NPT or bolt head?
Thanks again for your help

That is #6 on the parts diagram it has a spring and detent ball on it. It is what is shown on your picture of the maintenance manual.

The 1010 I have I bought for parts (under carriage and 6 way blade) so I hadn’t ever changed the transmission oil. I went and looked it over this morning and on the bottom center of the transmission case about 4” from the back edge there is a 1/2” pipe plug. 3/8” Allen wrench to remove. Unfortunately for me about a 1/2 gallon of water came out before the oil. There is a hole in the belly pan to access the drain.
I can sent you pictures if needed. The drain plug is # 25 on the parts diagram. It just doesn’t really show you where it is.

Well now that’s interesting news. So it’s not located on the side of the transmission case, it’s located on the bottom of the case? That certainly makes a lot more sense in terms of draining fluid but is totally at odds with the ambiguous photo of the location in the owners manual, the shop manual, and the exploded parts diagram!

I too have an internally mounted 6 way blade and there’s a slid plate on the bottom, but the only hole through the skid plate on the back half fog the machine is for the hydraulic reverser drain. There is however a plug with a square fitting that is visible from the rear of the machine when looking through the slot where the drawbar is located. Here’s a photo of it (drawbar is on the right, square plug is visible just above the splash of yellow paint remaining on the drawbar—in the blacked part of the photo )

If this is it (and without a hole in the skidplate) I’m going to have a real mess. I appreciate your efforts on my behalf (oil and water!)

[newwood]

I forgot to say, it’s located exactly on the midline just forward of where the drawbar attaches. But that’s a lot more than 4” from the back plate of the transmission box
