Tranny leak

Well my tranny is leaking real bad out a
seep hole on bottom. I tried to find in
manual what seals and where they are so I
can replace them. I do realize I have to
pull engine to do so. Does anyone have a
pic and can tell me what ones would leak?
Was told there 3 possible ones 69 jd 450. I
believe ots the hdl tranny
 
John, more than likely it?s your engines rear main seal leaking. How bad is it? If it?s just a tiny drip here and there I?d leave it alone. I?ve got two old tractors that will drip some but not enough I?m constantly having to add oil so I?ve left them alone for several years now. But if you?re having to add oil on a regular basis it?s time to separate it and replace the seal. What part of the country are you from? I?m married to a Bates....
 
Its definitely hydraulic fluid from transmission.it comes out n a steady stream.i can fill 2 gallons up in about 10 minutes. There is a hole in bottom of tranny that suppose to have a cota pin inwas told. It's coming from that hole. Someone drilled it out bigger and added a line to it that ran to a gallon can. I guess they didnt wanna fix it. All I no is someone told me I had to pull engine and change 1 of three seals on tranny. But couldn't find it in the manual. My dad was from Oregon
 
Roger that, good luck with it....
My wife?s family is from Alabama, thought you may have been some of her distant kin, but not likely
 
Ya maybe 2000 years ago lol. Anyway the hole is in bottom of bell housing..not tranny. I assume there is a couple seals in there it's coming from. I dont wanna pull the engine grrrrr I just did steering clutches...might say hell with it and run it till it blows up. Only have a small piece of land I wanna fix
 
Yes it sounds like the transmission input shaft seal is leaking,,I would change the rear main seal too while the engine is out...
 
The info should be in the HLR (Hi-LO-Reverse) transmission section of your manual, but they don't spell out there is a seal here , here, and here, as line items. You need to read the repair procedures and see where they say to replace a seal , O-ring, or gasket as part of a component overhaul, like the clutch pump. I expect you are looking at a John Deere technical manual for a 450. I don't have one so can't tell you the pages in your manual, but from the manual I do have information is in the HLR section. You will be looking at seals, O-rings and gaskets in the transmission front cover area and the Clutch (or HLR) pump which is around the input shaft. You will need to study the parts book as well to find the parts you need.

Here is a link to the transmission area of your crawler. There are two transmissions here so be sure you look at pages for the HLR transmission.

I have one but like you said it doesnt
point them out. I'm sure I'll figure it
out..I bought a PDF file which is the whole
book. 566+ pages. I just didnt no if I had
to get into the tranny or if it can be down
after I pull engine. I sent you the file
and you can save it for your self if ever
needed lol
 

You can work on the front of the transmission in place, after you remove the engine and clutch housing. You may be able to see just where the oil is coming from when you get in there.

Thanks for offering you manual.
 
If you have an email I can sent you the
manual pdf file. Cant send it through here
cause it doesn't allow them I guess
