I installed a new speedo drive on my 75 MK3 a few weeks ago... put it on with the spacer on the outside as per the exploded diagram in the manual. When I installed it the speedo worked briefly, then stop working completely. Just got around to looking at it and here's what I found:
The end cap is missing and the guts of the unit are gone. Is this something that could happen with incorrect installation or is this something only a defective unit would do??? I am pretty sure I installed the drive properly, although fitting the drive over the left axle was tough, the drive had to be lapped to slide on easily. That could have been due to paint decreasing the ID. I also got the ears of the drive in the slots, so I am at a loss... totaling about $140 if this is my fault!
I also noticed that the cable end that goes into the speedometer is too short and doesn't engage the internal gears:
The exposed end measures just under 7/16". I bought both the drive and cable at the same time from Old Brits... I guess I need to know if others have had drives disintegrate like this and if the cable end is too short. Thanks in advance.
