hmmm...not sure that sort of thing is necessary.
One of the design "features" I dislike the most about the small-block rear drive. Any scratches need to be polished out before reassembly, or it'll be a leaker.
Again, I mean absolutely no offense.. but.. it is obvious that your experience level is not up to deciding what is and is not necessary. As Charlie saysIf the scratches can't be polished out, it will need a sleeve.
yes, just a thin paper/card gasket. with the bearing race not seated correctly i do wonder if someone has been in it before me. it never leaked previously. so what would you suggest in relation to thickness of spacer? what's the purpose of them and are they also card/paper or metal? cheers
Please inspect VERY carefully. This rear drive should require TWO paper gaskets and one, thin steel spacer. The paper gaskets usually stick to the casing or the cover or to the spacer. The stuck together pieces can often look like one. Like a very thin sandwich. The spacer is critical to maintaining a proper position of the crown gear and thus proper engagement of the helical pinion/crown interface. I can't imagine that the factory assembled it without any spacer. Time for some professional expertise to set this back correctly.Patrick HayesFremont CA
i will gently lift out and measure the spacer. thanks.
got it! the spacer looked like the casing material to me...but just looked and yes the spacer is present and the gasket underneath. i will gently lift out and measure the spacer. thanks.

i was going to use the word shim but have seen them described as spacers too. what i wasn't expecting was more than one of them but that's entirely feasible from what you have said. i shall just reassemble in the way they came off as i had no leaks or issues. thanks.
Good luck...if you change the bearings or the hub which the seal runs on the box will need re shimming.You just "might ' get away with a new seal on a refreshed hub but in my experience both the hub and seal have needed replacing. And that's on a couple of drives...caused a lot of frustration having to redo every thing several times over before the leaks would finally stop.Add to which they did not immediately leak again
I'm confused. How would two shims work? There are paper gaskets to seal between the cover and the shim and another gasket between the shim and the case body. With two shims you end up with a bare metal-to-metal interface and that wouldn't seem to seal for long. You could use three gaskets, but that really starts to impact the spacing measurements. Need more insight here.Whatever, don't be tempted to use adhesive sealant. You'll never get it apart again.Patrick HayesFremont CA
That's how my V50 III came from the factory: gasket/shim/gasket/shim/gasket. I use sealer (Permatex 300) and have no problem getting them back apart.
interesting how there are so many variations. so there should not be a metal shim directly on the casing? looks like i need to order another gasket in that case.
mine was gasket, shim, gasket, shim. i intend to assemble it all together and fill with oil to make sure there's no leaks before painting.
