Firstly, is it really a viscous LSD? They are pretty reliable. If so, the "Viscous Part" has a separate oil supply to the oil lubricating the crown wheel and pinion. It operates in a similar way to an auto's torque convertor or a viscous fan. Internal oil flow generated by differing rotation speeds is used to "lock up" the drive between the driving and driven components. If the viscous part isnt working, its probably leaked its (separate) oil supply.
Uncertain if this is exactly how to fix it, but I would remove the viscous centre from the crown wheel. Before dismantling the viscous centre, check how much of the correct oil it should have inside, (it wont be a lot) and after dismantling how much it actually has. If insufficient oil, your viscous centre problem is identified, except for why the oil leaked out. If you can answer that, refill with the correct amount of the correct oil sealed into the viscous centre and reinstall on the crown wheel. Keep us informed on what you find. ----- Original Message ----- From: "robert leavey" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, May 31, 2005 5:02 PM Subject: R200 Help > just a couple of qustions > > Can the viscous part of a viscous LSD be fixed after it has wore out? > Is doing a oil change going to help it any? > > > robert > --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [email protected] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
