hi just wanted to know has anyone ever flipt a diff in a sierra 3.62 lsd case. or is it possible ? so it would turn the other way cheers paul
No room to flip the diff in the case, but you could just turn the whole thing up-side-down and block the breather (perhaps adding another one). If
you're gonna run it in the reverse direction too, it might not like it (may just be noisy) but then again it might be fine!

Not designed to run in opposite direction.

Hello,
The dutch importer overhere is building the MK indy with a shaft driven bike engine but that runs the wrong direction.
He is flipping the sierra diff, bloks the breather, and making a breather tru the filler plug.......
He's not having any problems so far and he build a few already, one is good now for 5000 miles.....

. I'd suck it and see... The mesh on the gears is design to go in one, loaded direction only.
Its OK in reverse for a small while but I think it would be very rough and noisy upside down. Especially if its come from an ancient Sierra donor
Think MK installed this setup in the Indy...
It'll work, you have a crush tube between the two pinion bearings, and running it in reverse loads this crush tube from the thrust created by the
hypoid cut. You'll get away with it on a bike engine because it doesn't have huge torque which would destroy this after a few heavy clutch
drops. You may get issues from the pinion bearings being starved of oil form being above the oil level. But lets face it, we're not going to be
doing 30,000km per year in these cars
Does it make any difference that it's an LSD?
My Sierra diff didn't like working upside down.
so i take it the diff will run upside down ok chaps? well i hope .its got to it lives in the rear of my imp faceing backward and upside down mad yes
hope it goes to plan cheers paul
Should be ok as the CWP are running as designed.
