Hello to all.

I have been a silent reader of the this forum for several years now and

am thankful for the advice that I have read.

I recently bought a 1980 John Deere 314 that i am setting up to plow snow.

I hit a snag however. It doesn't appear that the sight glass tubing for the hydrostatic transmission is

complete. I have seen the parts chart and have a general idea how to route this. I understand

where the sight tube system begins, at the fluid reservoir. I guess that it ends at the axel housing.

I would like to put rebuilding the sight tube system on the back burner until next summer if possible.

1) Do I really need to rebuild this sight glass system?

2) Is there a way that I can measure the fluid level via the fill tube?

3) I know that the tractor uses 5 quarts of hydro fluid. How much fluid does the 54 inch plow need?

I will be buying a service manual when the funds allow but  not yet.sight tube.jpg SAM_1973.JPG SAM_1976.JPG

Here are pics of the extra transaxle I have. I can send you pieces if you are missing anything. The clear hose is readily available at an auto parts store. I would fix it before winter and not risk ruining the pump.

I have a question. If it is supposed to be a site glass, why is it buried inside the frame!

There is a notch out on the rear where the hose runs through so you can check on it. How ever im not sure where it should be in the tube but i know i can see it on mine. Its located on the left side if your looking at the gt mine was full of dirt grease an crud. after i cleaned it out i reliezed what it was.

Travis, perhaps you could answer one more question for me. After I removed the mower deck, my front PTO spins for

10-15 seconds after shutting the tractor off. Is this normal operation?

If there is no belt on the pulley free-wheels for a while after the engine is shut down - so yes, that's normal.

Glad the pics helped.  Keep me in mind if you have any other questions as I have a service manual that covers the 300/312/314/316 with the Kohler.  If you need info the serial number of your tractor is necessary to get the right info for you.

This is quite funny I found this post. I just brought home my childhood JD 314 and while unloading it off trailer I found some sort of an oil leak. Once in the garage I found it to be the sight tube. It had cracked and was dripping. I put some cardboard down and paper towels and headed in the house to check on the family. I came back out to my man cave and found a lake of tranny fluid on the floor. Finally got it cleaned up and under control and found the entire tube set up was shot. Not realizing I could have just bought new tube at a hardware store, I went to the dealership. I bought new filter,hose,clamps and fluid. Went home and put it all together and started to fill it. It only took 1 3/4 quarts and the entire tube was full and it was leaking out of the filter/breather.
My question is should I drive it a little bit to "burp it" or what? I did go out and buy an oil can to pump it in but I'm not going to play with it until I get this figured out.

Any info would be helpful

:wave: Welcome to the forum!

I don't think the tube should be completely full!

The fluid should be between the top and bottom of the loop that goes thru the frame.  Run it some but I expect you will need to drain some fluid out.

Drove it around the yard and it must have burped. I added another 3/4 of a quart and it's right where it should be. Prolly will have to add more as I drive it again.
