Planetary hub oil seal

[Roger]

Tage,

Well I checked out my 7745 front hube for oil level this evening and I am glad to report I am only marginally below max level even though I have gone over 1500 hours since I bought the tractor without ever checking or topping up.
I now see the filler plug for the rear hubs but I do not see a smaller plug to act as a level indicator. Do you know how the proper level is indicated for the rear hubs.
I do see a smaller hex bolt but it is located below the filler lplug and is a little too near the bottom of the casting to act as the level indicator.
What do you think.

In the rear hub, the filler plug also are the levelplug. You fill up until the oil comes out from the the filler hole. It is the same for the front axle, you have the plug on the left side of the tractor, when you fill the front axle take it slowly, the oil have to go the whole way to the othen end of it and if it is cold it can take a little time.

Regards Tage W.

Thanks Tage. I thought that might be the system on the rear hubs.
On my front axel it is different than you describe. The filler plug is on the left side of the axel as you describe. It is a 27mm hex plug. The level indicator is right in the middle of the axel however. In the centre of the axel facing forward there is a round plate about 170mm to 190mm diameter kept in place by about 8 or 10 bolts. In the centre of that plate there is a 12mm hex plug which is the level indicator for the front axel. At least that is what I use to guide me.I checked it last night also and the oil level was ok. Last time I topped this up was 500 hours ago.

Thanks for your help . I really appreciate it. Thanks again.

Roger

Hey Roger,

Do you not have an operators/owners manual for your tractor?

Hi,

I do not have an operators manual but I did order one a few days ago from tractor-manuals .com. I hope to have it in a week or 10 days and hopefully it will cover the basic upkeep and servicing requirements.
I am hoping it goes into the braking system as I have what appears to me to be a problem with the cylinders mounted on the back end of the tractor which kick in when the brake pedals are pressed.
From looking around this site I am guessing that these are what people refer to as "slave cylinders". I looked up the Fragokov website last night and it seems to me that they call these units "Brake Control Cylinders"
In any case they look to be like I could replace them myself without getting in a mechanic. My main concern would be on how to bleed the system of air in the process. Maybe my manual will show how to do this.
I am also wondering if it would be good practice to drain and replace the brake fluid every once in a while. I believe that brake fluid absorbs water over time and can become less effective as a result. Do you know anything about this.
