Is this a plate or viscous front LSD?

[razza]

Hi all,
I pulled this from a JDM Galant VR4 gearbox. I dont know whether it is plate or viscous. I had trouble getting the 3rd photo in focus however you can make the teeth out inside of the housing. Can someone please advise.

Cheers!!

Nope, thats a mechanical plate type LSD.

Do you want to sell it?

Looks like Viscous filler ball holes as seen in my broken LSD to me.

Cheers !

undo the phillips head screws and take the hat off ......then take another pic of inside. but I am thinking visc

My apologies, I read this from my phone, didnt see the first pic. It's more than likely viscous. Its odd though, as the viscous's I have, you couldnt see the gears, hence at first view it looked like it was in fact mechanical.

Just take a photo of the driveshaft splines, thats the easiest thing to check.

Yep, looks like a viscous front LSD to me too. I just look at the circles and squares on the side of those ones particular shaped LSD's because the viscous and mech LSD's in that shape look almost identical lol.
The viscous front LSD you have there is almost identical to a mech Ralliart front LSD, but the Ralliarts have the circles and squares right next to eachother in the same row. The viscous LSD's have the circle and square holes staggered, with the squares right next to the speedo drive gear. At first glance it would be easy to mistake it like Runuts did

looks the same as my Ralliart LSD...

Looks like a viscous LSD tp me. Check the top photo, and you can see the fill hole (plugged with a ball bearing) for the viscous fluid.
The teeth in the housing are the side and sun gears. I dont see any mechanical plates. Hope you have the "special" longer splined driveshaft that goes with it !!

Here's my Ralliart front plate type LSD. See how it looks very similar to your viscous unit, but the square holes in the side are in a different position. Thats just a quick check..
Also, from underneath looking at the ass end of the threaded crownwheel bolt holes, the viscous is chamfered in the centre where the Ralliart mech is a 90 degree angle.
OK kids, let's see what's inside the circle window today (1-way)

Just another pic for comparisons sake...
