I've never heard this. (I only have the two earlier T1 Bentleys.) Could you photo this note for the readership? I've only ever heard of the removal of the washer under the CV itself.
My 1979 edition of the Type 1 Bentley has the following caption for Figure 3-4 on page 6 of the Transmission and Rear Axle chapter:
Type 1 Bentley wrote:Driveshaft and constant velocity joint components. The hose clamps, pinch clamps, cap and lockwashers are no longer used (see text).
However, the text it refers to makes no mention of the lockwasher deletion. On the next page:
Type 1 Bentley wrote:NOTE - As of July 1972, the hose clamps, pinch-clamps, and separate cap and boot were discontinued. Instead, the driveshaft was given an additional ridge to secure the small end of the boot. The cap has been combined with the boot for a more effective seal. The new cap and boot combination can be installed on earlier models. The pinch clamp must be retained unless the new-type driveshafts are installed.
Nothing there abut tossing lockwashers in the trash.
I've also been mulling over these Schnorr washers. I don't think they were original equipment. Every CV lock washer i've ever seen was flat, not conical or dished like the Schnorrs. Unless the Schnorrs permanently flatten out when you torque them down? Is that the case? It doesn't seem likely.
So my question now is: if the original washers always were flat, and we are now replacing them with Schnorrs, should we be torquing the Schnorrs down more than the original washers in order to compensate for the extra resistance of the dish?
