More 912H Questions - Transmission

[Guest]

I don't have my manual handy, nor perfect memory but on my 712H I believe you are supposed to push down the "release" that puts the transmission out of action (so you can push the tractor without tran / engine brake) before checking fluid level.

Hi, When the tractor runs the oil in the tranny warms and the air in the transmission case expands creating pressure. If you check it on the left side there is a street ell [pipe fittint] about half way up. Screwed into the ell onthe top side is a little fitting with a small hole in it, in this hole is what looks like the head of a small nail. On the inside is a spring. This is a pressure release. Before you check the transmission fluid you need to take your fingernail and pull this up. this releases the pressure in the case. If you don't and you take the fill cap off you get a skin softening bath. Hope this helps. Good luck, Al

So . . . I got the new battery in and the tractor started. I noticed a slight whine from the transmission which I attributed the cold (although I have noticed a bit of dripping from the rear end over the past few months). I drove the tractor about 3 minutes, into my shop, and then figured I would check the level of fluid in the transmission. When I removed the fill pipe cap (straight off the back of the tractor) hydraulic fluid came out. I quickly put the cap back on, and retreated to the house to look in the operator's manual to see what I had done (always look at the directions after you try to fix something). It appears that I located the correct filling location, but why did fluid come out? It was about 10 degrees last night, and I had not run the tractor for over a month. What should I do now? Do I need to drain the transmission and replace the fluid with a hy-trans fluid? Should I replace the filter while I am at it? Thanks in advance for your assistance.

Some one had told me once that at the factory they fill them higher but that could be wrong. Also where you on level ground.

I was on level ground - perhaps there was some residual pressure in the system - anybody have an idea?

And like Al says after lifting the spring loaded pressure relief cap the level should be 1" below the top of the open pipe extension.
