Today I decided to change out the Hydro oil on the 1450. I started out by checking the level in the differential. That was full, so let it go for now. The hydro has been working just fine, but I had no idea how long since a filter change, so off came the tires and seat pan. Fairly simple process, 3 bolts per tire & 7 bolts in the seat pan. Next i placed a pan under the tractor and pulled the 'drain' plug. Let it run out of there and proceeded to remove the 18 bolts holding the cover on. A little prying and the cover came loose, along with a lot more fluid. Drain plug is way to high to get it all out. The fluid was not that dirty, but had a yellow cast to it. Not looking like Type A fluid was all that was in there. Here's some pics:

This is the knob I fixed up for the Drive/No Drive:

I went to Ace hardware and found the knob with 3/8 threaded stub on it. The Shaft stub is 3/8" also. I just bored the threads out of one end of the coupling nut and tapped in an 8-32 bolt to fit into the hole there. Works pretty good.

A view with the seat pan removed:

The wrench is on the drain plug. Note how high it is!

Here is the cover. note the color of the fluid.

Here's the filters. Nice comparison shots.

I did not get a shot of the inside of the box. My bad!

Next is the Hydro tag. It reads Hydro Gear. Model 90-2029. Serial 01-KA    19764

Here is the differential tag. It reads 2409 & under that is 008610. Guessing model and serial.

Here's the seat pan, top & bottom.

And here I have it going back together. Be advised, putting the cover back on is a PITA! I had to find 2 short 1/4" allthreads to align things. For the filter and spring, I held that in place with a putty knife until I could press the cover down tight enough to hold it in place.

I refilled it with 2 quarts of Dextron III. This put the fluid about 3/4" below the fill hole. I understand it is supposed to be 1", but hope this will not be an issue. Got it all back together and drove it around for some time. It worked as it should, so I got it back together right!

 

EDIT: Filter is a New Holland # JAC545440

Up yours! You almost need three hands putting that cover back on. All thread can be your friend, I used one short one in the lower left hole as I left the left seat bracket on the rear end. In the upper right corner, one sticking out at least 1-1/2" will work. I did take the right hand bracket off. Have a big pan handy as oil will go all over the differential when you break that cover seal.

If you choose to change the differential oil, notice the angle of the fill plug. That will make filling with the 80-90W very creative. The drain for it is on the bottom.

Does anyone know if these filters are still available? If not, can that be cross referenced to a Stens?

If one is still available, you'll be lucky! Haven't found a cross for them as yet! Think I got one of the last ones when I did this. I kept the old filter so if you find someone that might make them we can check sizes.

   I read this post a couple times but it does not say which plug is the fill plug.On the pump side there is a large bolt a small bolt and a hex, allen on top.Also if I pop the rear cover off to drain is the gasket reusable or will I need to try to find a new one?,Any help would be greatly appreciated.New member here.

  Thanks

:wave: Welcome to the forum. In the first post, second pic, there is an air vent fitting in the upper right of the cover. That is what I used to fill it with. I was lucky with the gasket sticking to the housing when I pulled the cover. Just take it slow and easy when removing it. Be advised that the filter is no longer available. We have not found a source for them as yet.
