What is the recommended fluid in the Ruxstell rear axle, is it 600W ?
Is there any substitute ?

I ruined a ruxstell once using 600 weight and was told by others that it is not able to flow thru reduced oil holes. So thru other instructors I use 90/140. Seems to work.

I'll second that. There is 90/140 in mine, too.

That's a lot easier to find...I would like to change it, no major hemorrhage that I see. Knowing my dad, it was probably filled 40 years ago and that was the end of it. I now it has modern axle shaft bearings and a grease fitting on the U-joint. Shifting is an art, especially downshifting with a Ruxstell.

I use 85/140 in mine. Just make sure it is up to the bottom of the fill hole. If you let it get down a little bit it can be too low to get into the Ruckstell housing and give sufficient lubrication to the planetary gears in there. My level was too low and I toasted the Ruckstell, but the ring and pinion had plenty of oil and were fine, it was just too low to get into the planetaries.

Dave, downshifting is done under load or power. When going uphill, don't touch the throttle, pull back on the shifter and put the clutch in and out. It will shift right into the lower gear. If you are in high and coming to a stop, pull the stick back just before you come to a complete stop, just the last few feet of rolling as you put in the clutch, and it will click right in without any noise or grind.

Up shift like a modern car. Close the throttle as you put in the clutch, move the lever forward, let out the clutch, and apply throttle. Very smooth easy, quiet shift.

I avoid oil with 'EP' additive in my TT Ruckstell. Make sure you get "non-EP" oil as the EP thing/goo/stuff erodes any bronze components in your diff.

GL-4 is difficult to find on the store shelf but is still available. GL-5 has the potential to ruin brass/bronze but it would take extreme heat to have any effect. I don't know if a differential or transmission, in good condition, could get hot enough for it to be an issue but imagine it will remain hotly debated for decades to come :>)

I've been using straight Sta Lube 140 for years, with no problems. If you fill to the filler hole, you will have oil running out your axle shafts.

Jeff, I don't have much trouble shifting it, I've got it down pretty good. The hard part is downshifting if you need to stop kinda fast. I have 26 rear brakes and can pull the park brake if absolutely necessary. But normally stopping...it doesn't stop well in high gear with the foot brake.
Getting rpm and drivetrain speeds the same is the trick, kinda like a semi truck.

Thanks everyone for the info.

I thought 80/90wwas what was recommended, maybe 140 in a hot climate.

80/90 is hypoid and 85/140 is usually synthetic.
