Checking hydraulic oil on 8N

Ken in Arkansas · May 27, 2009

To accurately check hydraulic/gear oil level in an 8N should the lift arms be up or down?

Try it both ways. You will find it makes no difference.

The ram cylinder holds about a pint. The drive train holds about five gallons.

The 'pros' say "take the btm. bolt out of the dipstick cover and it's full when the stuff runs out"> Mark dipstick accordingly.

This is a timely subject. I just took my bottom cover-bolt out and gear oil ran out. But looking in there with a light proved the gear oil level was an inch BELOW the hole.... There's about a 1-inch stub or nipple that makes up that lower bolt and it holds oil that is "slung" up there by the gears. I added about 2 quarts before the fluid level was up where it should be. (Small drip at lower lift arms for the last two years. I know. I know. But some fool has brazed the lift-arm bolts to the case, probably to stop a leak he didn't understand.)

'G', just reporting what I have learned, it may be that you just got 'splash' leakin' outin'. Hope one of the 'pros' will fill in the blanks. Did you try filling with the bolt out ? I know the crankcase filling instruction on my 60 is "fill untill it comes out the oil check hole". HTH b

That's been my experience with 8Ns too. No dif. I figured that maybe the 9Ns and 2Ns were different though.

Yep. That's how I do/did it. With the lift DOWN. Not that it matters.

If it takes 2 years to lose 2 qts, I'm not likely to take it apart just to fix the lift-arm studs that drip a couple of drops when I put it up for the night.
Old corn-sacks soak it up pretty good and make good fire-starters when burning brush.

Well fellas, it is still not clear if I got the thing right. I would like to know what the answer is. Ken, thanks for the pics. Hey ! every day is a 'school day'. b
