Unless there is a leak at the seals the deck gear box nor the tractor gear box should not require any scheduled lubrication. If the seals are leaking you need to replace seals. But if oil is needed the manual calls for SAE E.P (extreme pressure) 90W oil. Just my opinion but I would use what the manufacturer recommends, especially if unit is still under warranty.<p>Jim
After the first hundred hours I used Mobil 1 synthetic 90 like your friend does and It works great. Never had a problem in the 700+ hours I've been running it. All fluids in my Walker are Mobil 1 synthetic, Engine oil, Hydros, Gear box, trans axles. Runs cooler in that little oven. Good Luck.
Guess I need to check a little further, I did not know that Mobile 1 had a 90W oil. At least I have never seen it around my area. <p>I do use Mobil 1 in my engine an hydro transmissions. <p>After I got my Walker I wanted to change my oil in the hydros at 200 hrs. The manual called for SE 20W motor oil. I searched hi an low for it but no body around here stocked that weight oil. I called Walker and they recommened the Mobil 1. Been using it ever since. Going to check with Mobil distributer today for the 90W.<p>Jim
Where do you guys find mobile 90wt? <br> I just replaced my center gearbox due to bearing failure. A little tip for you do it yourself types, don't forget to time the blades when you replace a gearbox.I overlooked this and had to take it back apart and reassemble it right.<br> Took a little while but it still beats paying a shop mechanic 50.00hr to do it.<br> My hour meter twitched out back a while. This repair is at approx 2200 hrs.<p>----------<br>Yesteryear L/S<br>Hollywood Fla
