10 bolt Eaton cover upside down?
Okay, I hope this works...first check out this link and look at the picture of the 10 bolt Eaton and take notice of where the drain plug is
http://images.google.com/imgres?imgu...UTF-8%26sa%3DN Now take a look at MY 10 bolt Eaton, and notice that the drain plug is up higher http://cgi.ebay.com/ebaymotors/ws/eB...482137824&rd=1 Can it be that the pumpkin was leaking from the drain plug, so the guy put the cover on 180 rotated so that the drain plug was higher, in an attempt to stop the leak? It would make sense, since the drain plug is higher up,so if it's leaking, the pumpkin could only empty out to the point of the drain plug? Rick |

Not that it matters, but that is the "fill" plug. These do not have a drain plug. You could definitely get more lube in there with the fill plug up that high. I can't remember if you can put that cover on upside down. You would think I would have done that at least once if it was possible as many as I have torn down...lol

that would over fill the rear if he filled it to just where you can touch it through the hole and it would foam out and leak

Short answer is: Yes, it's upside down.
Does it matter? It's up to a professional to say. Yes, you don't want to over-fill your case. I believe gear sets need to (max) be 1/2 submerged at most, but that's just been a rule of thumb I've heard, but I would defer to someone who builds axles for a living.

Thanks
Thanks for the replies. Now the question is, was the cover put back purposely upside down to minimize a drip/leak situation, or was it done by accident?
I'll have to check it tonight more thoroughly to see exactly where it's dripping from. Rick |

I would think the higher you fill it the more it would leak.

I'll bet it was done on accident, to put it on upside down would be asking for more problems.

The cover is on backwards, mine is towards the bottom. I thought 1960-62's only had this rearend? Did they have this rearend all the way until '72?

GM built that 10 bolt for ages. Not sure when they discontinued it.
As far as the differential cove, filling it that full will cause problems. The oil will foam. Also when the oil gets hot it expands, and the vapor normally goes out the vent. But with that much oil in it, some will be forced out the axle and pinion seals because there won't be enough room. If the owner wasn't smart enough to put the cover back on right (it will go on either way) you have to wonder what else he did wrong on the truck. I can't see flipping the cover around because the plug leaked, it's cheaper to buy a plug seal than a cover gasket, and a whole bunch easier.

I think you are correct Jim, 47 to 72 for the H0 axles.
