Been almost a week since I briught my new (old) Yannie home. Thought I had everything up to snuff and realized I had not checked the front axle fluid yet. Nothing in there! Desperately needed to use it today to collect firewood so filled it (with all the oil I had) to about 1/2" below the plug. Should it be filled to the top? And I can't figure where the old oil went. Used it in 4WD for a couple hours today up and down the mountain with loads of firewood and never saw a drop leak out. After being parked in the barn for 4 hours after being done couldn't spot any leaks. Just another thing that irks me about the dealer. As I said in an earlier post, They washed it and put a for sale sign on it. Any reputable dealer would at least check the fluids before selling. BUYER BEWARE! No regrets though, with a little TLC and regular maintenance this should be the last tractor I ever need. Very impressed with it so far.

Checking fluids BEFORE purchase is the buyers job. It can take several hours, (days), for the oil to bleed down into the knuckles, speeded up if you open the vent screws. Not crucial, but you should end up with oil just covering the axle. Hope it was not run enough without oil to cause damage.

What weight oil did you put in there? I believe that all the front wheel drive tractors take EP80-90 gear oil. Someone correct me if I am wrong. If you put lighter weight oil in, run it a few hours to flush all the axle assembly, then drain while hot to remove any impurities in the oil. Does you fill hole cap have a small dip stick on it? If so, it should be marked to where you can fill to the correct level. Let us know what's going on.

I used 90 weight gear oil, and no dipstick on the cap. It is just above the axle now. Couldn't check it at the dealers place cause I didn't bother bringing tools with me. Figured they would do the basics like fill all fluids.
Jared at Gorilla tractors told me some of the Yanmars that come from Nippon have grease packed into the knuckles because the farmers didn't want oil dripping into there rice fields. Jared buys used Yanmars as they arrive off the boat from Japan and that is where is has run into this before.

Some even here on the forum have recommended a "flow-able grease." I understand that it is quite good and does not escape as gear oil might. When I bought mine it had grease in the front asle, but even the grease was "leaking" out the top of the knuckle. On tear down I discovered that who ever reassembled mine in VN put the seals in backwards on the top of the knuckle. When I rebuilt the knuckles I put in gear oil. I have had some come out the vent for the axle, but that is all.
My FIL packs boxes with grease if they start leaking. He has several that have gone for years with grease in them. However, I recommend using the gear oil and just sealing the axle or boxes so that they hold the oil.

Interesting, I had not heard/read that before and always assumed the grease was added because of leaking seals. I doubt that grease can spread enough to do an adequate job of lubing, and if I had a FWD with leaking seals I would try Lucas Power Steering Sealant in it. It's about the consistancy of 90wt and I have been using it successfuly in my rotary cutter gearbox for about 5 years now because of a leaky output seal.

As long as it is said to take for 90wt to seep down into the lower knuckles, I doubt that anything much thicker would ever get there.

I do not know Norm, it was coming out the TOP of my knuckles. It seems to move and flow pretty well. I agree that it would be much better if the grease were put in there when it was torn down, but then it would not be necessary--however, in this case, there already is 90w in it so adding the flowable grease would just thicken the mixture and I am sure that it would flow to where it is needed.
