You can also pull the rear seat bottom up (just yank hard on the front of it) and look on the list of option codes under it. Then look up the codes to see what came on the car from the factory. If it has heated seats there is a very good chance it has an lsd because lsd and heated seats were optioned together as part of a cold wx package. marshall -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jamie Howton Sent: Saturday, April 09, 2005 8:16 AM To: [EMAIL PROTECTED] Cc: bmwuucdigest@uucdigest.com Subject: Re: [UUC] 1993 e36 325 coupe On Apr 9, 2005 1:08 AM, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > Thanks again, > Just one other thing, how can you tell the difference between a > standard diff and an lsd?

Better to leave it in gear, or park, with the parking brake off. With an open, the other tire easily rotates in the opposite direction. With a LSD it will take 50 to 80 ft-lb to turn one wheel and the opposite will turn the opposite direction. The amount of torque to rotate the wheel is a measure of the condition of the LSD. This only works with clutch type units, Gerotor, Quaife and other types are tested differently.

The LSD will rotate both output shafts in the same direction when you turn one of them by hand (and hold the input shaft), the open diff will be in opposite direction. The BMW LSDs are typically stamped with an "S" on them inside a rectangle in white paint (the open diff isn't) and the LSD will have an "S" in the metal tag (the open diff won't).

It is literally not significantly different than any other RWD car such as a Mustang. $700 is a little steep for a clutch installation, most shops charge $350-$550. There are only really a few critical things to keep in mind during the installation: 1) Different-size bolts hold the transmission to the engine. I suggest that you remove them circumferentially, marking a starting point, and use a permanent marker to number the bolts. Having them in proper order for re-assembly will save a lot of time. 2) BMW torque values for transmission and crank bolts are critical - get a Haynes or Bentley manual. There normally is a very frightening special tool required for installing an E46 (and E39, Z4, E60) clutch. Welcome to the future - with new and improved ways being found to screw things up, BMW (and other European manufacturers) now use a Self-Adjusting Clutch (SAC) whose sole purpose is to keep the clutch pedal engagement point the same through the clutch duty cycle. A "non issue" problem for most people, in reality the SAC causes many problems; premature clutch failure from over/under engagement, a wooden clutch pedal feel, and generally less torque capacity than a similar-sized conventional clutch. We can also discuss the shattering drive straps which cut or crack the transmission bellhousing. The special tools that are required unlock the SAC mechanism, and reset it if required during installation. For those reasons, the E34 M5 hybrid conversion that UUC offers for the E46 was principally designed to eliminated the dreaded SAC mechanism. Very important clarification - it's not a direct M5 clutch, but rather a hybrid of an M5-style pressure plate (we build a "sport" version with even more clamping force) and a custom clutch disk that has the newer large spline size that the E46 M3 shares with the E39 M5 and E31 V12 models. This final design is a very robust and durable clutch, and we offer a variety of clutch materials depending on your intended use of the car. For most street-driven and light track use M3s, we recommend our basic organic facing to retain OE smoothness. - Rob Levinson UUC Motorwerks * 908-874-9092 * http://www.uucmotorwerks.com On Apr 9, 2005, at 3:09 PM, Craig Robson wrote: > My clutch is going out and I don't feel like paying someone $700 to > change > it for me.
