Hi 

managed to get myself a D7 that had been restored some time ago but had not been used. First shake down and 1 main issue is the speedo drive twisting with the wheel. On inspection not sure the spacers are right (want to upload pictures but haven’t figured out how!). The spacer between the drive and wheel bearing is just under 1/2 inch but had two washers either side? Also the spindle threads are a transition fit with the hole in the speedo drive. The drive turns freely and has grease (screw in place of grease point)

No manual, anyone show me what the correct nut/washer/spacer set-up should be please

Many thanks Stewart, managed to find more on the site, as you say I need to spend a little more time rummaging around on here and learn how to put photos on.

C5931DB8-F3D6-4BBF-8397-EE9136698A13.jpegOk reassembling rear wheel with spacers as per diagrams on here, if I tighten the nut on the speedo drive it locks up tight on the wheel hub hence why I guess the previous owner had added three extra washers. Any ideas?

Spacer measures 0.467" 3 extra washers combined 0.18"

The speedo drive body should be clamped tight (by the big nut) to the inner race of the wheel bearing by the spacer. The spacer is sized so that the two pegs on the rotating part of the speedo drive can enter the two notches on the hub BUT are not pressed in tight against the back of the notches.

I would check that the driveside bearing is fully seated in the hub and the retaining ring on the driveside is fully tightened. 

Cheers

If it helps mine has a shim inside, maybe 1mm thick or so, and a washer on the outside and the thin  nut (half nut). Also according to drawings, I believe. 

I agree something has to be inside to shim it out to stop it binding, if that's what it wants to do.
